		<description>Great article and yes, in this age of trends like &quot;toxic people&quot; and &quot;haters&quot; becoming standard for speaking your mind and calling a dud a dud, articles like this will probably become extinct. 

I don&#039;t have a Canon. My camera is a Nikon D40 and there are forums and sites like this full of discussion about obvious defects in the D40 as well as others, but the attitude seems to be, swallow and take it. Have it repaired and stop whining. 

I am more afraid of this generation of compromisers than the products being sold so blatantly with obvious defects. Indeed the term, -- laughing all the way to the bank fits, but the customers are crying all the way to the bank, shelling out time and money to repair or replace cameras that even the slowest of us could determine the defects were known.

Look, I have a floor model television. 27 years old with the original remote and instruction booklet. Bought it used a few years ago. Picture--fantastic. Sound? Makes me want to cry that I will never get built in speakers that amazing these days. It&#039;s been going on the blink the past few months so I finally bought a new one. You think it will be around working that well 20 years from now? No. It won&#039;t. Back in the day they seemed to have a better standard and pride in producing products. Today it&#039;s about the money and churning out products whether they work as they should or not. Marketing is all that matters.

If you make a living with your camera these defects are unacceptable and the attitude of the companies who design and sell them equally so. 

My camera has hot pixel problems. I am told it will cost 200 dollars to have it fixed and I will have to wait 3 or 4 weeks to get it back. 

I&#039;m appalled that the store where I bought it could say this so easily. The camera is at this point, only one and a half years old, bought brand new. I told him I would be in as soon as I rob somebody and get the money to have it repaired (smile).

Could it be that the positive reviews, the opportunities to make money by promoting and marketing these products (also the product freebies) is producing a &quot;gagged&quot; community of people who are willing to let others buy these products knowing they are defective?

When these camera work well they are simply amazing. This is not a put down of SLRs but seriously, craftsmen and professionals are supposed to be antsy about the tools they use to make a living. If a carpenter bought a defective drill he would expect the store or company to take it back pronto and replace it no cost to him. 

Photographers must not look at their cameras as tools and the core of their livelihood.

P.S. Brand names mean nothing. Treat them all the same. They will screw you. Nikon is getting as many complaints on workmanship of their products as Canon. This is massive disregard and an unacceptable trend of careless design and manufacturing.</description>

		<description>I continue to use the defective lens, and take multiple shots hoping that one might be acceptably in focus. I don&#039;t use it very often though because it is not reliable.</description>

		<description>I see you own this lens too ... with its defective design ..... how did you overcome it for use in your work? Calibration by Canon resolved your issue ? Or you just continued to use a defective lens?</description>

		<description>Harry, I&#039;ve not seen reports of lots of issues with Nikon products. You may want to look for such reports. But even since the D3 and D300 nikon has had some very solid product releases.</description>

		<description>It is really is surprising! because Canon used to be good! but like you said Canonâ€™s latest product releases have not been very good. I think I better wait at least 6 months if not more in this situation. Does Nikon has simmilar issue too on their products?

Many thanks.

		<description>Hi Harry,

If I were you I would wait at least 4 months after the 1D Mark 4&#039;s general availability before I buy one. I&#039;d wait for the reviews and for comments from other people who have used one. Canon&#039;s latest product releases have not been very good and if you read my 7D post you can see why:
http://blog.kareldonk.com/canon-eos-7d-review-noisier-than-40d/

You don&#039;t want to spend money to find out the product has issues later. And if  you do get one, make sure there&#039;s a return policy, so you can return it for a full refund if it doesn&#039;t work. And as soon as you get it, test it thoroughly to make sure it works well. If not, send it back.</description>

		<description>Hi Karel,

I am using 1Ds MK lll at present and have decided to up grade to MK lV, do you recon that is a wise step! or shall I stick to the MK lll for the moment? I have definitely canceled buying 50mm f/1.2L lens after reading your comment.</description>

Read what I have written about the 5D Mark II before you buy one:

We&#039;ll have to see if the 1D Mark 4 is going to be good.</description>

		<description>We have a wedding photography business in Edinburgh. We generally work very fast and in some tricky lighting situations.

I am also seriously fed up with Canon&#039;s poor customer service and the need to constantly spend money recalibrating  lenses. I have the 1ds Mark 3 and the 50mm 1.2. 

I like to think we deliver sharp pictures and combined with the need to use relatively high shutter speeds (125 +) to avoid camera shake (too many pixels apparently). The need to shoot wide open is increased. I also don&#039;t like to shoot over ISO 400. It just isn&#039;t that good, especially for Â£5500 when compared to Nikons D3. 

So we are awaiting the release of the 1ds Mark 4... what will we have to put up with next?

Is the new 1D Mark 4 up to much? Or should I settle for the 5D mark 2 as the next purchase?</description>

		<description>WOW, you guys are harsh! I understand these issues can be very frustrating, but if you look around at reviews (both pro and amateur shooters) you can compile a problem list with every product made (regardless of brand) and I think that&#039;s what you&#039;ve done here. This is especially true of large aperture lenses where togs are shooting wide open on in a large aperture range they have little experience working with. Also, this particular lens is different than the 50mm f/1.4 in that it has shallower depth of field by design. 

Take a look at this shot: http://photosbyrene.com/files/img_1347.jpg A little blemish touch-up was done on her forehead using PhotoShop Elements, but other than that, the image is as captured. Look at it at 100% and you&#039;ll see the difference in focus on the left side of her face vs the right. Is that a back focus issue? NO, it&#039;s the lens design and it gives me a look not many, if any, other lenses can. 

I have this lens and haven&#039;t had any of the problems you outlined (perhaps I got lucky and got a god copy). That includes shooting in AI-servo (predictive focus) or &quot;one-shot&quot; using a focus lock technique. This lens has allowed me to capture shots I would not have otherwise been able to get with any other lens. Most of what I shoot is low-stage-lighting performance action and is extremely demanding on equipment. 

If you got a bad copy OK, go get a good one or pursue sending it into Canon for a tweak because this is a lens every serious Canon tog needs in their bag!!!</description>

		<description>Now I know I&#039;m not alone. My 50 f/1.2 back focuses heavily. It is a major disappointment. Thank you for pointing this out. Now I know there are many defective lenses floating around.</description>

		<description>It is important for a lot of reasons but I have just taken my 50L lens in because the autofocus IS accurate but when I manually override it which I do out of habit it back focus to hell and back which is totally unacceptable for a lens costing Â£1100! It has nothing to do with chromatic aberration it is as fundamental as not being able to justify your fee because your shot is not sharp where it should be! Oh and by the way it does suffer from pretty severe chromatic aberration as well but nothing that Lightroom can&#039;t fix. I used to shoot Leicas and transparencies in the old days too but standards are higher now and the resolving power of modern chips far outstrips even Velvia 50.</description>

		<description>I agree... I&#039;ve had a 50L... I knew something was up with it... Its a damn shame that you get the &quot;luxury&quot; lenses and worry about getting a sharp copy... Its all I see these days in forums... People worrying about the quality of their copy... Its just what happens when a company services more and more people... Unfortunately, its a business... There are losses and gains and pros and cons to both... The market is flooded with people who DON&#039;T know enough information on photography... There are more of these folks vs pros/experienced people... Quality is no longer something you get from large companies as a benefit to you... They call it quality, but its really just attributes that make them able to compete with others in the market for their OWN gain...</description>

		<description>What is this fuss all about?
Even some Leica M lenses have this type of spherical aberration. It&#039;s always been a property of many superspeed lenses. And photographers learned to work around the issue.

But I guess nowadays in the age of &quot;auto everything&quot;-SLRs, pushing one button must be enough.</description>

		<description>There&#039;s always the 50mm f1.0L instead. Floating element, many other nice things about it too. Too bad it&#039;s so expensive and hard to find.</description>

		<description>Thanks for compiling this valuable summary. I nearly went ahead and bought and this lens, but its issues and flaws are completely unacceptable -- especially at the price point Canon Aus. were asking [AUD 2799].

If they bring out a fully functional version, I&#039;ll definitely get one.</description>
