Re: Canon fixed the focus issues with the 70D!

Canon has had my EOS70D back three times, if it was a simple micro focus adjustment needed why haven't they just done that.

Re: When will canon fix the focus issues with the 70D?

@70Downer - This is probably the most practical advice for this problem. It hurts to sell the camera to a person knowing there is (or there may be) a problem. So I sold it to to the shop from where I bought it. When the problem was mentioned all over the internet and even when many people has written about sending to Canon and getting it back, when I had contacted Canon, the first response was - We have never heard of this problem!. 

 

For people thinking about buying this camera, I recommend staying away from this product. This is not a pro camera and most people buying this camera probably are only hobbyists and not making a living shooting pictures. They don't have so much time in testing all the lenses and correcting them for perfection. The thing is even with correction, you may not get the 100% satisfaction that you expect. When othere cameras in this segment can achieve this with so much ease, nobody should even bother to buy this or try this in the first place. 

 

And if you must buy this, please spend all the time during the return period in only testing it for this proble


I have been shooting canon since the AE-1. I tell everyboidy I know about how bad the 70D is. Telling them to not only stay away from the 70D but Canon all together. It would be different if you got a bad one and you sent it in and they replaced it with a known good one. Instead they keep sending you back the same camera  not fixed several times. After 3 trips and paying for shipping 3 times they finally got mine fixed. You should not have to do that with a new camera. Especially after its a known problem that MANY people are experiancing. Between that and the bouce flash bug that every 70D has and they refuse to even acknowelde you would think it would be a simple firmware update. but instead canon just burries their head in the sand and says "i dont see a bounce flash issue"

Did you send the lens into Canon along with the camera?

The complete camera kit which included the EF-S 18 - 135 lens.

You understand the actual 70D focus issue (reported in a few early cameras) would not affect the EF-S 18-135 lens?

Re: Canon fixed the focus issues with the 70D!

There are so many "experts" here that chime in in such condescending tones that it is pathetic.  I have come to my own conclusion that all of these people that keep coming back to tell everyone that it is a problem with the user, not the camera, are actually paid in some capacity to do so.

 

Here You specifically talk about the original problem that a “few” cameras had, and with a snarky tone exclude the 18-135 - I assume because it's smallest aperture is 3.5, but the 'original' problem with a “few” cameras effected 2.8 and faster lenses.

 

Well, you might like to think you’re an expert, with your condescending tone, but my 70D had a viewfinder center square  focus issues with ALL of my lenses at various apertures. The problem showed with all my canon lenses including the 24mm stm, 40mm stm, 50 mm 1.8, 18-135 stm, 70-300 and 24-105 L. It also had the problem with the sigma art series 18-35 and tokina 11-16.

 

I personally own all of these lenses, and tested them per exact directions from canon, using a tripod, outside, in good lighting. I took the exact same picture of three different objects spaced out at different distances, focusing on the middle object. I took the pictures with the view finder center focus square and also the same picture with live view, and did the same at different apertures and also at different zooms when applicable. I made a multipage chart cataloguing each picture setting, and sent it all to canon. The viewfinder center square focus was so far out with every lens ant every aperture that micro adjusting wasn’t even an option.

 

Canon told me to send the camera in, which I did. They would not tell me what they did, except to say they “reset settings, checked and verified firmware, cleaned sensor”.

 

The camera works much better now, and in fact I am now in the territory of needing to do the micro adjustments per lens that everyone keeps talking about.

 

I already know what your reaction is going to be – because it’s the same condescending snort I received earlier in this thread – you’re going to say that I obviously don’t understand what the original problem is or was, because it was only at 2.8 or faster, ect etc etc.

 

What I will tell you is that my camera – my 70D, had a problem with live view center focus, so save you breath and quit telling people here that it is all “dumb users that don’t know what they are doing”. Since getting my camera back, I have added the canon 100-400 L mk2, and have a kit that has cost near or over 8000. This experience was so disheartening that I just about sold everything and gave up my new hobby altogether.

 

To sit there and tell people the problem is with them – that they are buying a camera so sophisticated that users can’t use it properly without extensive training, which was release it as an upper end consumer model, please just stop and hear yourself. Canon, Nikon, and all the other camera makers including all the new mirrorless systems all make cameras that are much less expensive and much more expensive, all that focus properly, even for amateur, beginner photographers.

 

I seriously considered giving up the hobby altogether, and also considered selling all my canon gear at a loss and going for the Nikon, but I was just too far into it and can’t afford to absorb thousands of dollars in losses to migrate to another system. Had I known about this issue before hand, I would never have bought the 70D, and as such I do not encourage others to get it.

 

I use the 70D now, and do enjoy it. I am getting great pics now, and am belong to various “70D user community groups” online, and everyone seems happy with their 70D’s, and I see pictures form these groups every day that are amazing. That being said, it was extremely frustrating for me, and even more so for those who send the body back and it comes back unfixed.

 

And still, nobody has commented on the issue regarding the 2 different firmware versions which were both named 1.1.1,. How can canon have two different firmware with the same 1.1.1 classification? I realize since you are just a “user” and not a paid representative (?) you won’t know about this, but the makers of magic lantern were having difficulty engineering their software for the 70D until they discovered that the different programmers, using different 70d camera body’s, were encountering 2 different firmware versions, even though both were called 1.1.1,. My personal theory is that this is somehow related to the issue, but since canon denies there ever was a problem, we will never know.

Which is an entirely diferent issue to the one the thread started with.

 

Again (and sometimes condescension it the only appropriate tone - deal with it): nobody - absolutely nobody - is denying that there are faulty 70Ds. You had a faulty 70D. No dispute there, OK?

 

What we're saying boils down to two simple observations:

 

1) There is NO single, pervasive, systemic issue with the 70D's AF - not wide open, not at any other aperture; and 

 

2) By an order of magnitude, more "issues" are down to the user than down to the camera.

 

Is that clear enough?

I didn't tell him the problem was with him.

 

I told him the problem with his camera that he described could be corrected by micro focus adjusitng his lenses.

 

He doesn't want to even try micro focus adjusting his lenses. If he doesn't even want to do that, but, instead insists that there is a problem that all 70D's have how do you expect me to reply?.

 

You stated that Canon did fix your issue when you sent it in.

 

Do you believe that Canon is continuing to ship known deffective 70D's despite being able to fix yours?

 

Do you think that after the previous poster sent his camera in to Canon 3 times, that maybe, just maybe the problem is with the user and not with the camera?

 

There is no systemic problem with the 70D's AF, in other words not all 70D's have an AF issue.

 

Again it is perfectly normal to have to micro focus adjust (MFA) your lenses.

 

At no point did I say that no 70D's had an issue, instead I have post a way to test and see if you do have an issue. Here it is again, if you think you might have a center AF point issue. This can be tested by micro focus adjusting the center AF point and all of the surounding AF points using the DotTune method and comparing your results. If the MFA setting for your surounding AF points varies by more than 8 from your center AF point you have an issue.

 

And as I previously stated if you think you have a problem with your camera send it into Canon for repair. But, after 3 trips to Canon it's time to consider that the issue isn't with the camera..

Re: Canon fixed the focus issues with the 70D!

 After all of my failed repairs with Canon, I have just returned my EOS 70D to the store and demanded a replacement.

What do you know? Canon did not fix the fault with this camera, I did! The replacement (so far!) seems to be working fine.

Again if you Google for "This lens is soft and other myths by Roger Cicala" it will explain why.

 

But, I'm glad you got a camera you are happy with.
