7D Mark II - Focus Discussions

Goodluck John, I shot with the Eagles for 2 days and I really like the results I have some blurry images but I know it is the operator error (me ) and not the camera. I am really happy with the sharpness this camera brings.

Hi Peter! Well I FINALLY got out to use my 7D2 today!
It's been quite a while but the rain finally cleared and the Unidentified Shining Object briefly appeared in the sky. Anyway here are a couple of rough and ready shots. They are straight from the camera (no editing/cropping etc) - unfortunately I didn't realise that the camera was still set to record JPEGs! Won't make that mistake again!
Anyway here they are and I would be happy to read any observations, but remember this is the first outing with this camera!

Wow. Awesome, I wish we have that kind of kingfisher here in Wa State. Those looks really good to me without any pp/cropping.

If you pixel peep they don't have the detail of the 1DX. However, being a 1.6 crop, you don't need to crop in so far and it's 1/4 the price! So I am pretty happy so far - no it's not a 1DX but it is very very good (fairly close) and exceptional for the price - so far.
I am hoping to have a go at some Short Eared Owls tomorrow so we can see how good the tracking is???????????????
Here is hoping!

2 tests to verify you have fully working camera-
1. put it in Servo mode, single point or spot point, shoot with high enough shutter speed and good light a hi-contrast detailed object. Is it sharp? If not, MFA, and repeat.

2. put it in Servo mode, single point or spot point, shoot with high enough shutter speed and good light a hi-contrast detailed MOVING object. If not, MFA, and repeat. If not, adjust First / Second SHutter to FOCUS Priority.

BOttom line, there have been some people with one of two issues that have needed repair a) inconsistent front / back focus or b) soft images, even at the plan of focus, during ai servo tracking of moving subject.

However, in all these pages, there are actually not many unique individuals that have needed repair for these and it is not a rampant problem of the sort.

This is what I've been doing. I've had some miss focus but I think I was just using to slow of a shutter speed. I did some tests of my kids running at faster speeds and they look good.

What I'm really impressed with is the ISO performance. It may be better than my 5d2 and I love the custom functions. I have 1 back button for single shot center and 1 for AI Servo.

All cameras will miss sometimes, it is often user error unfortunately! As per my previous posts I haven't tried the tracking on my 7D2 yet but it seems to latch on to static subjects quickly and accurately - so it is looking promising.
Please remember that any observations I make are relative to my 1DX so bear in mind that if I think it is half as good then that is high praise. After today's outing it looks like it may be 3/4 as good - high praise indeed in my books.
I have high hopes for tomorrow if the weather holds.

The 7d2 matches the 6d for low light AF acquisition in one shot.

Thanks for verifying this Lester!

Read this. Many like to use spot all of the time but it does have a specific purpose. I like the part about “Precise” is not the same as “accurate!”

There are though, several people, that have had several bad bodies in either exchange or repair. While the one side claims the problem is a verybsmall percentage, there is the other side that claims there is a high percentage of bad bodies. I think it falls somewhere in the middle. Like I said, several people have had multiple bad bodies.what are the chances? Im betting there are many that don't look at files close enough to even know there is a problem. Just test the camera thoroughly in your return window. Once it expires you'll have little luck with a resolution with canon after reading this thread. Even if it were .00009% affected, canon cannot seem to fix those. So test it out.

The return window can be amended to a degree.

....and if I read this right one would be able to upgrade to a full term (up to 3 years from date of purchase) CarePAK Plus plan.

I also like this http://www.learn.usa.c​anon.com …s7dmkii_zoneaf_​afpt.shtml

I like the part about a major difference between expanded and zone being expanded does not dance around the viewfinder to chase an erratically moving subject, whereas zone does.

Hey just a quick question for you, why would you have 1 back button for single shot center and 1 for al servo . I just use back button all the time and switch between
single and servo. Just asking to learn more about this camera and the different ways people set them up.

So you don't have to do any switching, just reach over to the next button and you have either mode at you disposal. You don't have to remove your face from the camera at all. You still have one shot and Ai servo option on the BBaf with Ai servo though.

For example, single shot is useful if you are wanting to use flash for focus assist

This guy explains it

Basically it just avoids having to take your eye off the viewfinder. For example if your shooting a bird on a branch I can use the center point single shot and if I see something moving I can simply use the other button to have AI servo without looking at the camera.

I also put ISO on the little lever so you can switch that too. Some really useful features on this camera.

Have you also tried the depth of field button to switch also, I find that works good also.
