How many pix along the horizontal?

Not sure I understand, Cropping the image has nothing to do with it being out of focus. I cropped to showcase the sequence easier.

Edit: Now you could easily say it front focused and I should micro adjust my lens but it also back focused several times. My point is it struggled to focus even though I was right on his face in perfectly good light. I moved my focusing point around slightly after viewing each image to try and see if it would grab focus anywhere else. My only guess is maybe the harsh sunlight on his face confused the AF.

Edit 2: Going through my images and the bigger the magnifcation I have on a subject the easier it is to grab focus however if your subject is smaller, The Auto Focus can have a harder time grabbing focus. This is a quote I read over at Canonrumors forums recently. I think this applies to my situation.

I re-read the manual. I'm not sure it corrects for angled movement. Mode 1 is moving up, down and sideways continually. Mode 2 corrects vertical when panning horizontal and horizontal when panning vertical. Is that your interpretation? I has been a while since I have thought about it.

Alan,
Welcome back.
Mode two correct in the perpendicular direction to the pan movement, any angle. It uses the X-y sensor to detect the vector and then only corrects perpendicularly. Just as you would want.

I agree with you earlier post, I had looking through the VC and seeing all the shake when IS is off.

Yeah, I did the firmware update a couple of weeks ago. There was nothing wrong with how the 7D2 was behaving, and I'm not planning on getting the Wifi card in the near future, but as another poster said, there could be other bug fixes in the update that Canon might be too embarrassed to mention. So I'm up to date.

Arch,
Curious whether they addressed any of the power hungry side effects? Does it still lose 1-2 percent of battery per day just sitting on the shelf if the battery is in?

Well you have to treat it like AI Servo and trust the process I think.

It is relevant to know how big of a crop it is, because that helps to determine how big the AF points were. The most unambiguous way to specify cropping is in pixels. You said 5x7 a couple of times but that was not helpful.

Posting the uncropped pic with AF points is even better than talking about crop sizes, thanks.

Most if not all your samples have portions of the image that are sharp. It looks like the AF was grabbing parts that you were not interested in. The actual size of an AF point is about double the square indicated in the viewfinder or in DPP. Taking into account that there might have been some wandering of the AF point due to camera motion, it looks like the AF system just found stuff to focus on that was not the animal's head. In some of the shots, the head was not even clearly visible.

I too have found that getting accurate and reliable AF is hard when the subject is small in the viewfinder.

Starting to noticing this camera struggle more and more everyday. Today is a good example. Single point and would NOT focus on this iguana for the life of me.

f3.2 - ISO 100 - 1/800th. Cropped to 5x7 just to show the full sequence. Also this was not a burst, Took 10 images in about a minute before he jumped off the bridge and not one of them is correctly in focus. I was pointing my AF point on his head and had no luck. I don't understand this considering they have tons of detail and contrast on their face.

Full Size:

DJ,
I now see you posted the overlay, and also noted that from and back focus occurred, and in spot focus, the actual af point is about the same size as the overlay square, whereas sing point is 2x height and 2x width. With this in mind, I don't believe the size iPod af point is causing the miss grabbing.

You are in servo, right? The only thin I can think of, especially since this wasn't a burst is the following. You indicated having trouble getting to catch focus, was it possible that you kept the bbf depressed and moved the camera around a little bit (say equivalent of 3-4 af points ? If so, you could catch focus and then move af point back over head but the af point might not have reacquire X and held due to too low of a TS setting. Since observing this focus acquisition issue that you have been posting about for so,e time now, have you at least tried TS = +1 or +2 so it actually is in focus where the af point show during the capture?

I would try shooting a flat object and see if you get consistent af.o

If we can't explain in it, I would say it really is time to send it to cannon.

Sorry, I don't know. Battery life is not an issue for me. That's because I never run out of juice. I was in Florida shooting every day a couple of weeks ago, had two spare batteries with me, but never used the spares. Charging every night kept me in power all the next day. I have to admit I was not shooting as many shots as some folks do, maybe only a couple to few hundred max per day. On the other hand, I was constantly on the Servo AF, and chimping too. But never a problem with my best battery, which is not its best any more actually, 2 years old now.

Do you think you could do a test? Look at the menus to get the current battery charge percent and leave it in camera for a day or two. If you go out to shoot, use a different battery and put the one you left at home back in when you get home. Write down the battery percent after each 24 hours and do this for a could of days. My battery loses at least 10% per week.

Doesn't matter as long as sleeping. But might as well try off but don't worry if you forget.

Most batteries steadily lose charge over time, specially if they are connected to a device even if the device is turned off. These days cameras sit in a standby/idle mode when "off" - 10% a week isn't bad, if you really want to save battery power take them out. I should try a similar test on 5DC and 6D.

Noting your edits.

The iguana target is not a good one for testing the focusing capabilities of the camera. The subject has a complex shape with parts at different distances, it is too small, and there are too many distracting elements that could catch the AF system. There is no way of knowing if the 7D2 is misbehaving or not from these shots.

Find a flat high-contrast well-lit object like a sign and do some tests on it. You should be square to the flat surface. Then shoot away and see what you get. Refocus each time. If the flat subject shots are good, then the camera is doing fine, and it is time to look at problems with the subject or your technique.

Yeah, I am not surprised at some percent loss per week.

I just checked my two spares, which were charged to 100% about 4 weeks ago and never put into the camera.

- Four-year-old Canon battery: 83%.
- New 3rd party Fosmon battery: 100%.

Wow, surprised to see 100% retention of the Fosmon. It drains fast when in the camera.
