By the way, for anyone not satisfied by the lower level Canon customer service for this 70D issue, PM me for the escalation number, which takes you to a much higher level service.

I have to say it's nice to see this thread being dedicated to discussing and potentially solving the problem rather than getting watered down with platitudes that don't really address anything.

Scoobert,

I heard back from Canon customer service about a hard reset. He said it doesn't really exist. You can do what was described above but it doesn't reboot the camera's computer: it just clears the language, date time, etc.... that's it.

So that's a dead end. I'm still having issues but mine are minor compared to what is described here. I'm slowing working my way to getting photographs as sharp as I did with my 60D but it's taking some effort.

Kim, could you do me a favor?

If you have a fast lens that's giving you problems, could you take a photo in the horizontal orientation and then one in vertical? I want to see if there is any difference in AF accuracy.
Actually a few consecutive photos would be even better in each orientation.

Gabe,

You take a look at these. The first three are better (more in focus, I think) than the previous two, but they all demonstrate the problem I'm having. Parts of our kitten's face are not in focus and this is with the 70-300L which only goes as wide as f/4. I'm using a monopod for all these kitten photos so I don't believe camera shake is to blame. I made sure I back beyond the minimum focusing distance on the first three as I'm not sure if that wasn't the problem on the early ones on the blanket.

I spend a couple hours with a focus chart and all my lenses... did MFA on all of them. I thought I'd be good but in actual practice, the photos were worse than I got on vacation with no adjustments so I put everything back to zero. I might have not been in the exactly parallel focal plane and I know that can throw off those tests.

Sorry for the book.......

I know you said you had no camera shake and are probably a better photog then me. But from what I have learned around here. Anytime people see a picture with a an effective 170mm focal length and a 1/25 shutter speed even with IS they are going to say camera shake...Even if its not :)

It might be you just need to get the MFA down on that lens. I seen your post in the 70D thread about just going one at a time as you shoot in the real world. If you want try this option.
I recommended this to toby and he he put up a video on it. It works to best with my 70D and you dont have to take a single picture to fine tune it.
All I can say about it though (and this may be the case for all fine tune methods) is that you test it under the conditions you are going to use it in. Because my MFA from outside to inside can be different.

I read somewhere too that there are batteries issues? Not lasting as long as it should? I will be coming from a 40D to 70D and the battery life on a 40D is fantastic.

I have seen a couple post about battery life being short. But mine does pretty good on batteries. UNLESS... You turn on the wifi, or use live view a lot. Mine is gripped but only because I have bigger hands and like the feel of a gripped camera better.

Yes all lenses, some worse then others. Strangely when it came back last time the tamron 28-75 2.8 had the best keeper rate. but the 50 1.4 and 35 f2 are about the worst.
I think it has to do with the tamron being a 2.8 max lens. I dont think it would do any better if I could stop it down to 1.8.

I wonder if the 70D sold in Australia has these issues or not.

The majority of the bad ones (that we know of) were sold in Germany. I think they are everywhere personally. Just not enough people know about the problem to test for it. Those that are getting out of focus pictures at wide apertures are passing it off as user error, just like I was. I thought no way was the brand new camera making bad pictures it had to be me. Until I started putting it on a tripos and testing it.

I'm looking forward to your update. I hope they have found a fix for it.

I am happy with the battery life also.

To me all the photos look great. Some I can see that the camera didn't focus on the eyes, but on the whiskers. Some I see the distance used affected the depth of field. Maybe step back further? Doesnt look like you had camera shake. But did you move your camera front/back? I have this same problem when taking close up/macro shots. This moves the focus area, like from the eyes to the whiskers.
Maybe try with a tripod, that way you can rule that out. Maybe increase iso to get higher shutter speed, or bounce a flash.
Also, I know some lenses dont like to be on a tripod with the IS enabled. Does this apply to monopod too?

As scoobert pointed out, 1/25 or 1/40 shutter speed indoors at f/4.0, is not going to deliver very sharp images, monopod, sofa arm rest or what ever.

You are really pushing the abilities of your 70D + 70-300L in that lighting scenario; not to mention you are at ISO 1600. I think the results you are getting seem to be what you should expect with what you have: you are expecting too much; a 5D III would not do much better.

A slow f/4.0 lens is not what you should be using indoors with bad lighting. It is not the 70-300L's fault nor the 70D.
