在2004年数码相机销售中，佳能保持着不错的势头，而且国内众多媒体在对此品牌的数码产品的测评中，赞许之辞可谓是让人眼花缭乱。不过老实说，还没有任何一款数码产品是十全十美没有任何遗憾存在的，而对于广大消费者来说，一款新的数码新型产品出现，最开始自然是惊喜，可在使用一段时间后，总是可以发现某类数码产品中经典出现的毛病，有时甚至是重大的失误，如果对它们作一个归纳，或许消费者会再次思考一下，当初花这么多钱（要知道日系数码产品的价格是所有洋品牌中最高的）买下这款数码产品，是不是值得？我们购买的，是服务，可问题出来后，这款产品所给予消费者的售后服务，是让消费者开心呢，还是让消费者堵心？
引导广大数码爱好者的消费，这无疑是我们的责任。而对于资深的数码FANS来讲，一些大品牌的毛病，他们自然比较清楚，但对于普通消费者来说，对这些响当当的数码产品，或许他们就一直认为值得购买吧，在掏腰包时，根本就不需要货比三家，特别是在对佳能这一品牌，更是如此。
实际情况是不是真的如此呢？我们就拿大家一直认为是日系产品中品质相当出色的佳能作一个解剖吧，看看它的数码相机是不是最具有性价比的物美价廉的数码产品吧。
下面剖析的这几款数码产品，是建立在众多消费者实际操作的基础上进行评述的，相信综合比对做得比较充分，希望消费者能够客观、公正的对佳能的数码产品有一个较全面的了解。
优势何在？让消费者心烦意乱的莫名怪胎：佳能A80
也许从某种程度上说，佳能A80满足了不少对数码相机一无所知可对名牌十分狂热的入门级爱好者们的期待欲望。比如它采用400万像素的1/1.8英寸CCD，最大光圈为F2.8－F4.9，镜头采用3倍光学变焦这点和A70相同，镜头采用2片非球面镜，配合大尺寸CCD感应器以及改良的成像处理器。而它的所谓优势，就是机器外观也比前几款漂亮合时尚了很多，同时机器内部元件有了革命性的改观，如镜头、LCD（与A60 70相比）、CCD、机身等等。
缺陷重重
如果你买了A80，最开始的印象或许就比较烦，因为A80的LCD巨小，也就1元硬币那么大，让不少消费者搞不懂为什么。
这款佳能A80让不少消费者是心烦意乱，譬如对时尚女孩来说，体积和重量方面比起同系列A70的101×64×31mm确实是大了一些。A80机身250克的重量再加上4颗AA电池，使的在轻巧性方面确实不具有竞争力。它的竞争对手富士F700的机身重量仅仅170克，而且还是使用重量较轻的一颗可充电锂离子电池。
千万小心A80的旋转LCD显示屏
最让消费者头痛的，当然首先是性价比。从价格上来看似乎A80很不错，可不要忘记了一份钱一份货，这款机型的LCD显示屏的分辨率只有6.7万像素，而在同档次机型中富士F700的LCD显示屏的规格为1.8英寸，13.4万像素的分辨率，另一款柯达DX6440的规格和F700是完全一样的，而且柯达和富士装备的还是室内/室外型显示屏，显示效果更好。
另外，如果不考虑有声的3分钟录像的话，奥淋巴斯的c5000似乎更加有可关注的理由，毕竟它是台500万象素的机器成像质量稍强。佳能A80使用的是4颗AA电池，使用成本是低了，在没有电力后，你可很方便地买到普通的碱性电池。可问题是，这4颗AA电池对机身体积和重量影响相当大，另外比较来说，可充电锂离子电池的使用时间比AA电池长很多，眼下可充电锂离子电池价格也便宜，这样比较，这一优势也没有了。
使用感受及点评：
最可笑的就是佳能A80使用的是USB1.1的传输方式。当然这些你或许可以说只是小事情了，不过用此数码相机久了，其它问题还是出来了。譬如，它的广角段存在着崎变得问题、如果在室内使用闪光灯，这款数码相机暗角现象比较明显；同时加了转接环后，闪光灯使用受限；这还是小事，旋转LCD看着比较单薄，似乎容易损坏，要知道如果坏了拿去修的话，恐怕就让你感觉相当累了，而且还可能有挨宰的经历哦。
让人恐惧的“E18” 错误代码：佳能A70
A70采用了DiGiC处理器，灵敏度范围也是ISO 50 - 400，也具有方位感应器，也具有3分钟动态有声短片拍摄功能，拥有300万像素CCD，还有采用的是铝合金前面板，机身顶部的转盘提供了类似EOS SLR专业机种的拍摄选项，总共有12种选项。
缺陷重重
从以上参数来看，感觉此款相机一定非常不错了，不过相信不少拥有此数码相机的网友有如此的恐惧经历：用它录了一段3分钟的视频，但是准备关机的时候却傻眼了，镜头缩不回去也出不来了，液晶纯黑的屏幕上显示3个字符“E18”当时心里就咯噔一下，一想完了。
这款A70是佳能公司出品的手动入门机型手机，上市价格在3000元左右，但它的错误代码“E18”（镜头单元/镜头挡板错误），让人相当头痛。错误代码“E18”表明出现了一个涉及镜头单元或镜头挡板的错误。或者如果您在操作相机时用力压迫镜头周边区域，也可能出现该错误代码。于是有相关人士教导人们一招解决方法：在操作相机时检查下列步骤以避免压迫镜头及其周边区域：握住相机，使您的手指在拍摄时不会触摸到镜头单元。确保在您将相机放回软套前，相机已经关闭。
A70的癌症―“E18”错误代码，据说有百分之四十五病发率
事实上在A70上市后不久就传出有一部分相机会产生此类错误，至少，不少消费者发现，在使用时，把镜头朝下然后关机会有此类问题，于是感到困惑，是不是马达动力不足造成的？虽然canon是全国联保，但是如果你没有随身带发票，肯定也给你异地维修造成不便。人家会说，确实可以维修，但是必须有发票和保修卡。如果你没要发票，只有保修卡，那就不好办了。无数的A70用户来到佳能指定维修点或维修站，佳能维修人员那不怀好意、装模做样的恶心表情，还要强装出一副为用户服务的态度，而冷冰冰的话语和举止却让大家满怀的激情上先泼一盆冷水，在听完这群佳能“维修工程师”的主观鉴定后，迅疾开出一张大面额的维修单。用户摸了摸口袋看了一眼维修单，无奈的说“那你说多少钱吧？”，心里却在暗悔：谁让自己买了佳能相机来着，只偶等着挨宰。
使用感受及点评：
佳能可是什么口都开得了的：“开机器300块，换件另算。”于是消费者终于明白了，原来佳能的售后“窗口”与它的某些产品一样，看来做的有点不人性化呀。或许E18应该属于canon产品的设计缺陷。其实在A75出现之前A70、A60机器E18错误出现的概率也相当高，可佳能的收费让人疑惑，不用开机器能解决的问题收费100元，内部问题，需要打开机器，收费250元，而换镜头组件需要600元以上，而你要检测是不是设计问题需要到canon公司修理处。没办法了，某些消费者只好解嘲了，DC这东西确实复杂，确实精密，300块钱修理绝对值得的。
笔者的一个朋友想找此相机的电路装配图，在GOOGLE上搜，中文页面好像没有，从一个德文站上找到的一个PDF文档，是维修操作指南，于是他按照上面的操作自己维修，却不小心将手指头击伤。
格外乏味、华而不实与性价比偏低的代名词：G5
在相当一段时间里，曾经有很多人看好G5，因为是佳能重点推出的机型。看好的它的理由不外是拥有F2.0的大光圈；四倍光学变焦镜头；内置ND中灰虑镜；相对较小的机身；可以旋转的LCD和电力强劲的BP-511锂电池，可以毫不夸张的说完全G5就是一部为时刻准备拍摄的人准备的。还有G5的模式转盘设计，配合中文菜单更好的让用户掌握等等。但是现在，大部分用户谈到G5都嗤之以鼻。
缺陷重重
一位年轻的消费者赞叹着说，G5拿到手上时，最初的那一阵确实给他们带来了一些意外的惊喜，可过后在实际拍摄中，困惑代替了惊喜，接着气愤代替了困惑。如取景器有时候会被镜头挡住，连拍也太慢，实际操作不爽。
更有许多中看不中用的东西，成为G5高价的噱头。比如G5所谓全新的9点眼控对焦，它要求摄影者把眼球资料录入到芯片上，这样在开启眼控对焦功能，眼睛对准焦点时，G5就会在该点聚焦。最开始时，这一功能确实给他们带来了不小的惊叹声，因为这明明是单反相机中的功能啊。但用户能够真用的上吗？一来对这些功能掌握不好，二来这些功能对成像效果影响并不明显，三是这些功能也只图个新鲜，新鲜劲过了，也就那么回事，毕竟数码市场新鲜玩意儿层出不穷多多多。
除了高像素高价格，G5还有其他靓点吗？
“老实说，我喜欢佳能，可现在G5实在是让人太失望了，几乎看不到什么新鲜玩意儿。造出这么一部什么G5。”一位年轻人如此强调着他看不起G5的理由，尽管语言让人受不了，作为一家之言还是由他说去吧。
“G4没有及时出现，其实是佳能对数码市场灵敏度丧失的表现。”既然是疑惑，那么总是需要人来解答的。有人便如此说出了他们的猜测。他们这样说，也是有他们的道理的。数码相机的竟然情况如此激烈，可佳能却迟迟不推出500万像素以上的高档机，仿佛置身世外。真能如此吗？可现在又推出G5，跳过G4，更证明了它迫不及待的心情。G5的推出，从佳能的角度看，也是在尼康、美能推出CP5000/5700以及D7i/D7Hi等重型机种后推出的，有点被形势推着走的意思。如此一看，佳能跳跃G4这个型号尽管让人疑惑，可也是无奈和势在必行之举。
使用感受及点评：
说到使用感受，一位业内人士对笔者说：“以它这么高的价格，再看看它的图像质量，综合考虑一下，这款相机实在是不具竞争力。”这也难怪，人们对G5的期待实在是太高了，如果有丝毫的不满意，加上这么高低的价格，也别怪人家会带着有色眼镜去看这款新机器了啊。还有顾客拿出尼康的Coolpix 5400，说它的质量与G5相比如何如何好，也有人提及索尼的DSC-V1如何厉害。
这款相机和G3一样，用的依旧还是那块8英寸面积的CCD。如果一款数码相机已经在朴素上提高了很多，而CCD没有任何的改进，消费者自然有怨言了。如今的消费者，谁买数码产品不讲究个外形，可佳能的这款机器握在手里，确实让人产生一种难受的塑料感，这一点远远不及索尼。索尼717让消费者有一种手感扎实，造型时尚且功能足够强大的感觉，这一点佳能远远不及。可见，产品的外形设计上，G5更显得陈旧而老套，布局依旧是G系列传统布局样式，功能键过于密麻地堆在机背上。
在拍摄效果上，G5拥有F2.0大光圈镜头。据说该镜头在实际操作中成象相当细腻，然而不少消费者也感到这种有点过分渲染，甚至会产生一种让人受不了的湿答答的画面。这样的画面，已经没有细节可言了。一位经销商朋友在饭后的的话，似乎道出了消费者们对G5的疑惑及经销者们的困境：“这款机器总体特性确实没有人们想象的那样好，性能非常一般化。另外，它的价格也有点昂贵，性价比低。”
现在咱们似乎可以得出这样的结论：G5的运气实在是不太好，当初有点生不逢时，因为它出场时，刚好与索尼F717及索尼V1、尼康5000相伴，这与G3刚出场时消费者对它的疯狂完全是两回事了。
伪品质让你期盼落空：让我们对佳能品牌说“不”
随着数码领域竞争越来越激烈，随着佳能业务链产品越来越丰富，特别是随着该品牌的数码相机产品希望囊括全部消费群体的定位，与其他日系大品牌一样，它的数码产品也开始出现质量问题。如果没有任何负面的新闻那倒真正成了大新闻了，产品虽然不敢说怎么样，至少充分表明了他的公关做的还可以。
譬如在数码相机这一块，不少消费者认为佳能与索尼比较，似乎更加专业，可我们在佳能A80身上也看到了同样的缺点，而且也相当的明显，例如它就秉承佳能系列机型严重紫边的特点，而且仅仅支持CF I卡，体积相对比较大。
就算是在高端专业摄影师所爱戴的EOS单反数码相机领域吧，佳能做得也有很多遗憾、缺失，譬如佳能300D，佳能厂商方面一起宣称，它拥有所谓的丰富手动功能。本来对于数码单反相机来说，用户枷M?芄蛔杂傻厥褂酶飨罟δ芤约暗鹘诟飨钆纳悴问???涯?00D与此背道而驰。我们知道，许多数码相机即使是在自动曝光模式下仍然可以自由调节ISO等设置，而佳能300D却无法调节。
揭开300D的面纱――你是否真的了解300D？
另外，300D在程序自动、光圈优先以及快门优先模式下无法使用中央重点平均测光，在全手动曝光模式下无法使用评价测光。在上述四种模式下，局部测光（范围较大的点测光）需要按下AE-Lock键以后方可使用。还有，300D的自动对焦也是无法自由选择的，300D的连续自动对焦功能只能在运动模式下使用……这看上去无疑就是剥削了用户自由创作的权利了。
300D的“劣迹”还不止这些，我们知道对焦辅助灯是许多数码相机配备的功能。300D也具有这项功能，但是她是设计在闪光灯里面的，使用时必须打开内置闪光灯，倍感不便。另外，需要注意的是虽然300D设计一个黑白屏幕作显示参数使用，但是这个屏幕在一般状态下显示信息并不全面，例如ISO感光度等就无法显示，这往往会误导用户。当然，由于佳能的市场策略运作有方，300D还是受到追捧的，但这绝不是因为她在功能参数方面的优势。
对佳能这样的厂商，对它的宣传以及价格误导，我们确实要我长个心眼啊。就算在时尚全能的S系列以及小巧时尚的IXUS系列数码相机方面，尽管一些入门级年轻消费者钟爱它们，可奇高的价格，让真正的掏腰包者痛恨交加。而佳能的生产与经典者们却在宣称，你可以选购性价比非常突出的A系列入门级数码相机嘛，它们在国内佳能的人气旺盛，潜在消费群体庞大哦。其实这种宣传是在行进一种心理暗示：即佳能的产品是无懈可击的。消费者对佳能数码相机产生绝对的向往是肯定的。可你真的买回了所谓的入门级产品，用了一段时间后肯定会发现手中的机器存在着众多让人难于接受的缺点。
看来，对佳能这一品牌，咱们得天天对它进行3・15消费者日才成，一不小心，就吃亏被宰，这是有目共睹的。佳能的伪品质让咱们普通消费者的期盼经常落空，因此让我们对佳能品牌说“不”，让真正的品质说话吧！

Call for E18 errors within the DCRP
--------------------------------------------------------------------------------
OK. I don't know about the rest of you, but I'm getting darn tired of the stupid E18 error rumormill. We have a lot of Canon owners on this forum, and I have yet to see any DCRP Canon owner report this error.
If you have had, or currently have, a documented E18 error on you camera give us the particulars. I don't mean hear-say on the web, but actual first hand experience.
I have many freinds and relatives that have purchased all maner of Canons, in the past 2 years, and none has had a problem with the lens sticking (E18 error) or any other fatal error that I know of.
I suspect that this is being perpetuated by someone unhappy with Canon and trying to keep a one-time problem out there as a worldwide and productline wide problem, when it is not.
Jeff if this survey is not to your liking then I won't feel bad about you killing it. But I think we need to put this to rest, as it has become a more common point of reference again, after disappearing for many months.
Or put your 2 cents worth in as well.

this is a quote of myself, from another thread:
i've worked in electronics/digital cameras retail (but not for long!) for the last 1 1/2 years and have never encountered the e18 problem. I'm not sure if this is relevant, but I know someone who fixes film cameras and there are actually many olympus stylus cams that have broken or stuck lenses, not canon. i'm really not sure why there is all this e18 talk in the air. i'll believe it when i see it.
this is not a quote:
i'd like to add that i've taken 8500+ photos with the A80 in conditions that include high wind, high wind + rain (got caught on a mountain-ish area in the rain without a cover, i took a few pictures and the camera got a little wet), on a boat with high wind, etc. and no problems. I keep mentioning high wind since i assume that is how something like a grain of sand would get in between the telescoping lens. again, no problems!

I recently bought a Canon A400 with a fitted case. When the camera was in the case, it accidentally managed to turn itself on, and when I finally was able to slide the camera out, at the bottom of the LCD screen was the E18 error message. When I restarted the camera it functioned just as usual. This error was not a Canon flaw, but an operator mistake.

Unfortunatly I have found my way to this forum as a result of receiving an E18 error on my Canon IXUS 40 (bought in Europe, it's the same as the SD300 in the US). The camera is 2 weeks old and has been treated very carefully, it happened earlier today after taking 2 photos and whilst reviewing them the camera made beeping noises and the E18 message appeared on the screen. Subsequent attempts to restart the camera have yielded the error and the lens is stuck in the extended position.
I am actually extremely upset about this because I bought the IXUS 40 (SD300) after my previous Canon IXUS 400 (S400 in the US) developed this problem suddenly after a year of trouble free use. Since I was just about to go on holiday I figured I didn't have any choice and took the "opportunity" so to speak to upgrade my camera.
So now I'm on holiday in Australia with a camera that doesn't work, for the second time in several weeks.
Therefore I can confirm that this problem is real and if it's not as widespread as is suggested on some forums I read before finding this one then it seems I have been rather unlucky.
Some posters on other forums mentioned the problem fixing itself after leaving the camera for a while, but so far this doesn't seem to have helped with my camera.
I will call Canon tomorrow, but am not confident of a resolution that will have a functioning camera before my holiday is over. I have seen a site explaining how to pull the camera apart and repair it, but given this will void my warranty I'm certainly not going to be attempting this. But if anybody has any other suggestions I would love to hear them.
Regards

E18 Error Twice
--------------------------------------------------------------------------------
I also was unlucky enough to experience the E18 error code twice. My S400 Digital Elph died with this error last summer. We had it repaired at an authorized repair shop in Vancouver at a cost of CAD $160. Six months later the same error code reappeared. The repair shop has offered to fix it for $130 this time (their warranty is only 90 days). Haven't decided what to do yet.

e18 1st day out of the box
--------------------------------------------------------------------------------
I just purchased the A85 from blueswitchdigital.com. The price was good, I got extras and free shipping. The camera seems easy to use and I was phsyched to take it out of the box and begin shooting a few images around the house. After 10 shots e18 appeared and the lens wouldnt close properly. I thought it was the batteries. I charged up the batteries again and tried the next day again several pictures and the e18 , this time the lens closed. One more day and try again same result. Very, very annoyed so I googled e18 and discovered that the lens is prone to this... How many people have experienced it or what % I do not know, most people dont bother to write about it and I doubt that you could get an accurate measure from Canon. I called the dealer and I had to pay to return it where they will check it out. So there goes that bargain as it cost me $11 plus an hour to run to UPS and back. I am requesting a new A85. I am assuming that they will experience the error too if they give it a short workout. If they try and tell me there is nothing wrong with the camera or it needs to go for repairs I will scream bloody murder and post this BS treatment all over the net. I have read many good reviews about the camera and you do get alot of features for your money. I was thinking of saying fuggetaboutit and asking for a diferent brand but I will give it the benefit of the doubt for now and wait to see what they say.

I've got one...
--------------------------------------------------------------------------------
I've had my Digital IXUS IIs for just over a year. ( So the warrenty has just expired ! )
Last week it started to have problems focussing, and then got the E18 error.
The lens is out and won't retract.
Looks like I'll be getting my scredrivers out ( Repair Guide )
My local Canon dealer says he will send it back to Canon , but they charge GBP50 just to examine it, and, off-the-record, suggested that he has returned "a couple of dozen" in the last year and that Canon have only repaired a few of them. (This cold just be a ploy to get me to buy something new from him ! )
Cheers,
Tim.
引导广大数码爱好者的消费，这无疑是我们的责任。而对于资深的数码FANS来讲，一些大品牌的毛病，他们自然比较清楚，但对于普通消费者来说，对这些响当当的数码产品，或许他们就一直认为值得购买吧，在掏腰包时，根本就不需要货比三家，特别是在对佳能这一品牌，更是如此。

更有许多中看不中用的东西，成为G5高价的噱头。比如G5所谓全新的9点眼控对焦，它要求摄影者把眼球资料录入到芯片上，这样在开启眼控对焦功能，眼睛对准焦点时，G5就会在该点聚焦。最开始时，这一功能确实给他们带来了不小的惊叹声，因为这明明是单反相机中的功能啊。但用户能够真用的上吗？一来对这些功能掌握不好，二来这些功能对成像效果影响并不明显，三是这些功能也只图个新鲜，新鲜劲过了，也就那么回事，毕竟数码市场新鲜玩意儿层出不穷多多多。
除了高像素高价格，G5还有其他靓点吗？
“老实说，我喜欢佳能，可现在G5实在是让人太失望了，几乎看不到什么新鲜玩意儿。造出这么一部什么G5。”一位年轻人如此强调着他看不起G5的理由，尽管语言让人受不了，作为一家之言还是由他说去吧。
“G4没有及时出现，其实是佳能对数码市场灵敏度丧失的表现。”既然是疑惑，那么总是需要人来解答的。有人便如此说出了他们的猜测。他们这样说，也是有他们的道理的。数码相机的竟然情况如此激烈，可佳能却迟迟不推出500万像素以上的高档机，仿佛置身世外。真能如此吗？可现在又推出G5，跳过G4，更证明了它迫不及待的心情。G5的推出，从佳能的角度看，也是在尼康、美能推出CP5000/5700以及D7i/D7Hi等重型机种后推出的，有点被形势推着走的意思。如此一看，佳能跳跃G4这个型号尽管让人疑惑，可也是无奈和势在必行之举。
使用感受及点评：
说到使用感受，一位业内人士对笔者说：“以它这么高的价格，再看看它的图像质量，综合考虑一下，这款相机实在是不具竞争力。”这也难怪，人们对G5的期待实在是太高了，如果有丝毫的不满意，加上这么高低的价格，也别怪人家会带着有色眼镜去看这款新机器了啊。还有顾客拿出尼康的Coolpix 5400，说它的质量与G5相比如何如何好，也有人提及索尼的DSC-V1如何厉害。
这款相机和G3一样，用的依旧还是那块8英寸面积的CCD。如果一款数码相机已经在朴素上提高了很多，而CCD没有任何的改进，消费者自然有怨言了。如今的消费者，谁买数码产品不讲究个外形，可佳能的这款机器握在手里，确实让人产生一种难受的塑料感，这一点远远不及索尼。索尼717让消费者有一种手感扎实，造型时尚且功能足够强大的感觉，这一点佳能远远不及。可见，产品的外形设计上，G5更显得陈旧而老套，布局依旧是G系列传统布局样式，功能键过于密麻地堆在机背上。
在拍摄效果上，G5拥有F2.0大光圈镜头。据说该镜头在实际操作中成象相当细腻，然而不少消费者也感到这种有点过分渲染，甚至会产生一种让人受不了的湿答答的画面。这样的画面，已经没有细节可言了。一位经销商朋友在饭后的的话，似乎道出了消费者们对G5的疑惑及经销者们的困境：“这款机器总体特性确实没有人们想象的那样好，性能非常一般化。另外，它的价格也有点昂贵，性价比低。”
现在咱们似乎可以得出这样的结论：G5的运气实在是不太好，当初有点生不逢时，因为它出场时，刚好与索尼F717及索尼V1、尼康5000相伴，这与G3刚出场时消费者对它的疯狂完全是两回事了。
伪品质让你期盼落空：让我们对佳能品牌说“不”
随着数码领域竞争越来越激烈，随着佳能业务链产品越来越丰富，特别是随着该品牌的数码相机产品希望囊括全部消费群体的定位，与其他日系大品牌一样，它的数码产品也开始出现质量问题。如果没有任何负面的新闻那倒真正成了大新闻了，产品虽然不敢说怎么样，至少充分表明了他的公关做的还可以。
譬如在数码相机这一块，不少消费者认为佳能与索尼比较，似乎更加专业，可我们在佳能A80身上也看到了同样的缺点，而且也相当的明显，例如它就秉承佳能系列机型严重紫边的特点，而且仅仅支持CF I卡，体积相对比较大。
就算是在高端专业摄影师所爱戴的EOS单反数码相机领域吧，佳能做得也有很多遗憾、缺失，譬如佳能300D，佳能厂商方面一起宣称，它拥有所谓的丰富手动功能。本来对于数码单反相机来说，用户枷M?芄蛔杂傻厥褂酶飨罟δ芤约暗鹘诟飨钆纳悴问???涯?00D与此背道而驰。我们知道，许多数码相机即使是在自动曝光模式下仍然可以自由调节ISO等设置，而佳能300D却无法调节。
揭开300D的面纱――你是否真的了解300D？
另外，300D在程序自动、光圈优先以及快门优先模式下无法使用中央重点平均测光，在全手动曝光模式下无法使用评价测光。在上述四种模式下，局部测光（范围较大的点测光）需要按下AE-Lock键以后方可使用。还有，300D的自动对焦也是无法自由选择的，300D的连续自动对焦功能只能在运动模式下使用……这看上去无疑就是剥削了用户自由创作的权利了。
300D的“劣迹”还不止这些，我们知道对焦辅助灯是许多数码相机配备的功能。300D也具有这项功能，但是她是设计在闪光灯里面的，使用时必须打开内置闪光灯，倍感不便。另外，需要注意的是虽然300D设计一个黑白屏幕作显示参数使用，但是这个屏幕在一般状态下显示信息并不全面，例如ISO感光度等就无法显示，这往往会误导用户。当然，由于佳能的市场策略运作有方，300D还是受到追捧的，但这绝不是因为她在功能参数方面的优势。
对佳能这样的厂商，对它的宣传以及价格误导，我们确实要我长个心眼啊。就算在时尚全能的S系列以及小巧时尚的IXUS系列数码相机方面，尽管一些入门级年轻消费者钟爱它们，可奇高的价格，让真正的掏腰包者痛恨交加。而佳能的生产与经典者们却在宣称，你可以选购性价比非常突出的A系列入门级数码相机嘛，它们在国内佳能的人气旺盛，潜在消费群体庞大哦。其实这种宣传是在行进一种心理暗示：即佳能的产品是无懈可击的。消费者对佳能数码相机产生绝对的向往是肯定的。可你真的买回了所谓的入门级产品，用了一段时间后肯定会发现手中的机器存在着众多让人难于接受的缺点。
看来，对佳能这一品牌，咱们得天天对它进行3・15消费者日才成，一不小心，就吃亏被宰，这是有目共睹的。佳能的伪品质让咱们普通消费者的期盼经常落空，因此让我们对佳能品牌说“不”，让真正的品质说话吧！

Call for E18 errors within the DCRP
--------------------------------------------------------------------------------
OK. I don't know about the rest of you, but I'm getting darn tired of the stupid E18 error rumormill. We have a lot of Canon owners on this forum, and I have yet to see any DCRP Canon owner report this error.
If you have had, or currently have, a documented E18 error on you camera give us the particulars. I don't mean hear-say on the web, but actual first hand experience.
I have many freinds and relatives that have purchased all maner of Canons, in the past 2 years, and none has had a problem with the lens sticking (E18 error) or any other fatal error that I know of.
I suspect that this is being perpetuated by someone unhappy with Canon and trying to keep a one-time problem out there as a worldwide and productline wide problem, when it is not.
Jeff if this survey is not to your liking then I won't feel bad about you killing it. But I think we need to put this to rest, as it has become a more common point of reference again, after disappearing for many months.
Or put your 2 cents worth in as well.

this is a quote of myself, from another thread:
i've worked in electronics/digital cameras retail (but not for long!) for the last 1 1/2 years and have never encountered the e18 problem. I'm not sure if this is relevant, but I know someone who fixes film cameras and there are actually many olympus stylus cams that have broken or stuck lenses, not canon. i'm really not sure why there is all this e18 talk in the air. i'll believe it when i see it.
this is not a quote:
i'd like to add that i've taken 8500+ photos with the A80 in conditions that include high wind, high wind + rain (got caught on a mountain-ish area in the rain without a cover, i took a few pictures and the camera got a little wet), on a boat with high wind, etc. and no problems. I keep mentioning high wind since i assume that is how something like a grain of sand would get in between the telescoping lens. again, no problems!

I recently bought a Canon A400 with a fitted case. When the camera was in the case, it accidentally managed to turn itself on, and when I finally was able to slide the camera out, at the bottom of the LCD screen was the E18 error message. When I restarted the camera it functioned just as usual. This error was not a Canon flaw, but an operator mistake.

Unfortunatly I have found my way to this forum as a result of receiving an E18 error on my Canon IXUS 40 (bought in Europe, it's the same as the SD300 in the US). The camera is 2 weeks old and has been treated very carefully, it happened earlier today after taking 2 photos and whilst reviewing them the camera made beeping noises and the E18 message appeared on the screen. Subsequent attempts to restart the camera have yielded the error and the lens is stuck in the extended position.
I am actually extremely upset about this because I bought the IXUS 40 (SD300) after my previous Canon IXUS 400 (S400 in the US) developed this problem suddenly after a year of trouble free use. Since I was just about to go on holiday I figured I didn't have any choice and took the "opportunity" so to speak to upgrade my camera.
So now I'm on holiday in Australia with a camera that doesn't work, for the second time in several weeks.
Therefore I can confirm that this problem is real and if it's not as widespread as is suggested on some forums I read before finding this one then it seems I have been rather unlucky.
Some posters on other forums mentioned the problem fixing itself after leaving the camera for a while, but so far this doesn't seem to have helped with my camera.
I will call Canon tomorrow, but am not confident of a resolution that will have a functioning camera before my holiday is over. I have seen a site explaining how to pull the camera apart and repair it, but given this will void my warranty I'm certainly not going to be attempting this. But if anybody has any other suggestions I would love to hear them.
Regards
Cam

E18 Error Twice
--------------------------------------------------------------------------------
I also was unlucky enough to experience the E18 error code twice. My S400 Digital Elph died with this error last summer. We had it repaired at an authorized repair shop in Vancouver at a cost of CAD $160. Six months later the same error code reappeared. The repair shop has offered to fix it for $130 this time (their warranty is only 90 days). Haven't decided what to do yet.

e18 1st day out of the box
--------------------------------------------------------------------------------
I just purchased the A85 from blueswitchdigital.com. The price was good, I got extras and free shipping. The camera seems easy to use and I was phsyched to take it out of the box and begin shooting a few images around the house. After 10 shots e18 appeared and the lens wouldnt close properly. I thought it was the batteries. I charged up the batteries again and tried the next day again several pictures and the e18 , this time the lens closed. One more day and try again same result. Very, very annoyed so I googled e18 and discovered that the lens is prone to this... How many people have experienced it or what % I do not know, most people dont bother to write about it and I doubt that you could get an accurate measure from Canon. I called the dealer and I had to pay to return it where they will check it out. So there goes that bargain as it cost me $11 plus an hour to run to UPS and back. I am requesting a new A85. I am assuming that they will experience the error too if they give it a short workout. If they try and tell me there is nothing wrong with the camera or it needs to go for repairs I will scream bloody murder and post this BS treatment all over the net. I have read many good reviews about the camera and you do get alot of features for your money. I was thinking of saying fuggetaboutit and asking for a diferent brand but I will give it the benefit of the doubt for now and wait to see what they say.

I've got one...
--------------------------------------------------------------------------------
I've had my Digital IXUS IIs for just over a year. ( So the warrenty has just expired ! )
Last week it started to have problems focussing, and then got the E18 error.
The lens is out and won't retract.
Looks like I'll be getting my scredrivers out ( Repair Guide )
My local Canon dealer says he will send it back to Canon , but they charge GBP50 just to examine it, and, off-the-record, suggested that he has returned "a couple of dozen" in the last year and that Canon have only repaired a few of them. (This cold just be a ploy to get me to buy something new from him ! )
Cheers,
Tim.
