I wouldn't have hesitated, but then your experience is identical to mine with the original 7D.  Let's hope your replacement is much better.

Don't get me started on the original 7D. You can probably find my 4 year old posts in here somewhere, ranting about how awful my experience was.

It gives me palpitations just thinking about it.

Killer video - thanks for posting!

FYI, I'd not recommend focusing on the zero marker after assembling the linked chart, for the reason above (the camera doesn't know which of the horizontal lines under the AF point you mean). 

Thanks for the correction!

The camera is going back to B&H on Monday and Adorama is shipping me a new one over night on Monday and if UPS delivers on Tuesday (Veterans day) then I'll have it then and I have that day off as our baby sitter can't watch our daughter that day so hopefully I do get it then!

I'll keep you updated. I'll also mess with the MA this weekend just to learn and see if it really does help but I doubt that it will.

Also - shoot in different conditions... get out and shoot in the day, see what the 7D2 does. It seems like your samples are all shot in low-light which, again, is where AF notoriously struggles.

I agree but in the same setting with the 7DI it worked fine... I did take some photos last weekend outside and the same problem happened, 1 out of 3 were out of focus.

I know you don't want to hear it again, but I don't think you should be using the 7DI as your point of comparison. Cameras are different and vary from system to system - especially models that are removed by 5 years. That said, you may still have an issue with yours, and an exchange will demonstrate whether or not that is the case.

Moving forward, I do not think you should be afraid/concerned with MF adjustments. I've never had a camera body that worked consistently with 100% of my lenses until MFA was performed. It's a painstaking/tedious process, but necessary for those among us who want repeatable/tack-sharp photos. Here is a good cut-out target you can make... https://dl.dropboxusercontent.com/u/29571216/MicroFocus%20Adjustment.v2.pdf

You need an angled and labeled target so you can determine if your MFA is in front of, or behind, your base condition. It's worth playing with/learning, so you can get better at it in the future. FYI - aim for the zero marker!

I am not putting down the camera, just saying that it is not for me as the difference between FF and this is vast. And since it will always be like that I will continue using FF till I can afford to. I believe now that the only reason to go crop is budget.

IQ and budget are not the only reasons people consider this body; many pros employ a 5D3 and 7D (now 7D2). With the buffer and FPS on the 7D2, there is simply nothing comparable in the class/price range...

5D3: 6.1fps, buffer maxes out at 18 frames
6D: 4.5fps, buffer maxes out at 16 frames
7D2: 10 fps, buffer maxes out 31 RAW frames!!

In three seconds of shooting on a 5D3 you've taken 18 shots and maxed your buffer - you get almost twice the shots on a 7D2 in the same time frame (not to mention the extra reach of crop). It's pretty astounding when you think about it. 

If you're not trying to capture the shot of an eagle grabbing a fish from the river, or the hockey puck entering the net, the baseball player swinging past the ball at the plate, or the race car driver making that amazing pass on the track, then the 7D2 is probably not for you. It is simply a specific tool for a specific purpose; one where both the 6D and 5D cannot measure up.

However, I'm rather irritated about the vast differences in sharpness between the models, for example the 60d looks very blurry vs. 70d/7d2 and the 6d is a lot shaper than all. Is this because of lens properties, aa filter, or... ?

This is the nature of pixel density and FF vs. crop sensors. Crop sensors cram more pixels into a smaller area. Think about it, the 7D2 has the same MP as the 6D and 5D3, with a sensor that is almost half the size. Even the 1D series employed a 1.3x crop APS-H sensor for a number of versions. Hence, the photosites on these crop bodies are smaller resulting in noisier (or "blurrier," as you call it) images. Canon, and all camera manufacturers have worked diligently over the years to improve the quality of crop sensors, and they have made great strides. But physics is physics, and you can only do so much with so much light, in such a small area.

I hate to stoke the fire, but I think recommending a 6D or 5D3 to the OP, or telling him to photograph a "moving" subject instead, is a terrible idea. Trying to argue that the 7D2 can only photograph sports/action, and is not suited for still subjects, is just, well, silly. It's a camera. Granted, it's a camera with a certain design intent, but it's not like we're comparing a Chevy Nova to a track-ready F1 race car.

The 7D2 is a mid-level pro-sumer body, designed to handle a wide array of subject matter and shooting conditions. It should certainly be able to focus on a child in a kitchen in relatively medium/low lighting conditions. Now, that said, low-light conditions are certainly where AF systems struggle the most.

I will finish this post off by saying this to the OP: After thinking about your posts/story more, the more I think your 7DI (which, based on your accounts, focused more accurately and repeatedly in all lighting conditions) is the likely outlier here than your 7D2. I use a 6D and 5D3 in my event work, and I constantly find myself in demanding situations where there is very little available light. I usually start events at ISO 3,200 and often push to 8,000 as required. Missed focus comes with the territory, and getting those tack sharp results in such conditions is a real chore. So, the fact that you think your 7DI is spot on, time after time in every single scenario, tells me you may have gotten incredibly lucky with that body. All photographers struggle with adapting/modifying their AF techniques as lighting conditions change. To expect repeatable/consistent AF in low-light is simply not realistic, and is not what you should expect with current technology. It's a sensor; it can only do so much.

This isn't the only lens this happens with. I'm going to end up having B&H send me another one in exchange for this one.

Please keep us updated.

The problem is that I can take these same shots with NO problem on the 7D, same lens, etc. I'm not going to shoot @ f/8 when I have a 2.8 lens and want that shallow depth of field.

Here's the thing, and I'm not going to tell you you're wrong, because I know the toils of being unhappy with AF. When it comes down to it, only you can decide if you're unhappy with your purchase. If, after doing a bunch of tests the AF just isn't what you had hoped for, and the experience is even worse than your 7DI, then I think you have more than justified to yourself that an exchange is warranted.

Lemons happen. Try a new body and see if any improvement is gained.

PS: Just keep in mind, this is a COMPLETELY new AF system with no relation whatsoever to the 7DI. Expecting similar results may not be fair. If you want to stick with the 7D2 you may find that you will need to tailor your shooting style to the new AF system, for better or worse.

I'm having the same problem, I even reset the camera back to factory defaults. These examples are with the flash. I'll try some without the flash and with my other 600.


First off, that second shot looks DANG sharp! no? And look where the AF point is, on an area with good contrast! That catch light probably gave the AF something to hone in on.

Now, here's the general advice: always try focusing on a point of contrast. AF has a difficult time focusing in low-light when everything in the sensor area looks the same. Granted, you have a dark nostril in the AF point, but in that shot it's primarily bland skin tone. Focus on the eye, or center the line between the iris/white of her eye in the middle of the AF point.

Help the AF out as much as you can in low-light; this can be done by centering AF points on areas of sharp contrast. It's worth a try.

When all points are selected, it's going to try to focus on the closest object - the fork in her right hand.

I noticed that too; you can see the cluster of points at the bottom of the DPP pane. It's focusing, just not on what he wants. Let's hope manual AF point control solves it.

I was using the Canon EF-S 17-55 2.8 and was roughly 3 feet away, sitting. I was using the focus assist on the flash. Using the latest DPP (4x) that was downloaded today.... it looks soft on the camera screen as well.

Let's start simple; use single, center-point focus, and see what it does. Take the flash off. Remove external factors, and let's focus on the camera/lens combo before adding in other differentials to the mix.

I've been down this road before, and patience is key. Don't throw in the towel yet, let's see what we can figure out first before jumping to get a replacement.

Post up your results.

And FWIW, and not to sound condescending, but don't always trust the camera LCD - a JPG preview is not the same as a RAW file.

FWIW, I just slapped on my 85mm and snapped a JPG of my dog from across the couch to check everything out. This is the first time I've ever used the 7D2, so it's stock out of the box. I turned off the auto-lighting optimizer, but all other in-camera settings are default. My living room is incredibly dark (it's well past sunset here in Colorado), but it did a great job with center focus. Single AF point (center), aimed at the catch-light in her left eye (photo-right eye), focused, and recomposed.

Canon 85mm lens, f/1.8, 1/80s, ISO 3200

Here's the JPG out of Lightroom - some contrast/WB edits, and no output sharpening...

Update: Added a 2nd version of the same photo with a smidge of sharpening on export; I think it passed the focus test.

I suggest you start simple; use single, center-point focus, and see what it does. Post up your results.

For this series I had been using all points but it doesn't matter if I was using a single point or a group. I pressed half way down, it looked good in the eye piece so I took the shot and repeated for the next shot.

Are you using the focus-assist beam on the 600RX; or relying on the lens/sensor alone? Also, what version of DPP are you running?

Here are two photos, hand held while sitting.

Manual Mode, F/2.8 @ 1/125, Canon 600RX-RT mounted to camera. Two consecutive shots. I can set it up on a tripod but I barely ever use one and may just ask B&H for an exchange, I don't have time to mess around with tests or micro adjustments, etc.

What's odd is, the fork is incredibly sharp and clearly in focus. Are you using focus/recompose? Local points? Sorry to be a pest, but I've been down this road before with my 7D1 and just want to try and pinpoint any other possible scenarios that may be causing this.
