You are not the first to have the mirror box replaced. Another member here had that done in about Jan of 2015. Glad it worked out for you.
Funny. I've been reading about this for nearly a year now. I got my 7D MII in April of last year. I exchanged it quickly with B&H because it wasn't focusing. I gave it a month or so of trial and error and couldn't get it to focus. I sent it in, got it back saying there were calibrations done.
It's not months later, I'm a little over a month away from the warranty being up and I still don't feel confident. I don't do any BIF photography really. Honestly I wanted the options and a good solid weathered body along with a good crop sensor. I've had several Rebel bodies before this and NONE gave me any issues close to this or at all. I have a hand full of lenses, ranging from Canon, Sigma and Tokina. Even a Tamron, but we won't go there. In fact, the Tamron lens hardly gets used because it's an 18-270 walk around. What I consider to be my lowest quality lens, so I can only imagine how bad the images would be. Otherwise I have a Sigma 50-150 APO 2.8, Sigman 17-55 2.8, Canon 50 1.8, Canon 85 1.8, Sigma 30 1.4, Tokina 11-22 2.8 and a Canon EF-S 18-135 (kit lens). None of these have given me a sharp image at all from this body.
So I wrote them yesterday and immediately they started to tell me my 3rd party lenses weren't compatible. Wait, what? I replied back with a rather angry email (kept it PG-13) and informed them that the Canon lenses were doing the exact same things. At all shutter speeds, apertures, ISO settings (Don't get me started about how dirty it gets above ISO 800). I also was told because I had them in DNG format in Lightroom, they couldn't verify the settings and I'd have to send them CR2 files. Ok so how are you going to compare the shots from my T4i to my 7D MKii? I don't store DNG AND CR2! SO I took some new shots. Blurry as all get out. Took more. Still blurry. I did them inside, outside, even shot at f/8 1/125 (I can keep a steady hand down to 1/60) and shot at 1/1000 shutter speed. Not one thing in the picture is clear. So it's not just focus, but clarity over all is nuts. I was shooting at trees with foliage around them so SOMETHING should have been in focus.
Long story short, I uploaded about 300MB of images to my dropbox, sent about 3 emails pointing to example shots and I'm waiting to hear their reply. As a courtesy though he said he sent me a pre-paid label to ship the body back and assured me I would have it back within a week or so. This is because I have a wedding to shoot towards the end of April.
After reading your post though, I'm wondering if the mirror box is my issue as well. It makes logical sense because the blurry images look like "shake" but at a ridiculously high rate. It's not motion blur, but like something is vibrating while the sensor captures. And I'm sorry but at 1/1000 shutter speed standing still on a calm day, tree bark should NOT seem blurry at all.
So thanks. Sorry for the long winded reply. First post on this forum. I don't really like joining Photo forums because some of us can be snobs lol. I consider myself to be more modest, even though I've got 15+ years and now 5 DSLR bodies under my belt.
