I hate to belabor the point, but here's what I'm talking about: same position, same bird, consecutive shots from a 10fps burst. The two previous were in focus, the next three out:

I know about MFA, I have solid shooting fundamentals. It just happened. I'm too early in my 90D ownership to determine if this is a common occurrence, or if something else in my environment caused the focus to drift. I'll keep shooting and see.

I've had this happen on my 80d. So, I just gave up kind of. I'll still shoot in servo, but only fire off 2-3 shot bursts unless it's a flight shot.

I don't know if this is at all likely, but we might want to remember that the 5Ds and 7D2 sensors have the same pixel density, so maybe there will be a FF version of the 90D's sensor.

//runs do do the math..

That would be the same 80+ MP sensor that the rumors have been bandying about for some time.

Very likely per one of the posts on CanonRumors

For sports photographers interested in 90D, I ran into this blog review of the camera with lots of football action shots:

i'm not sure about keeping up with the speedy 4-0 niners squad...but gotta admit, the 90D was pretty good with my 6-year old nephews soccer team...i think only 3 shots in total were out of focus...

A couple more quick shots from the weekend. Being so large and out in the open, these have to be some of the easiest birds to take pictures of. I can only imagine trying to get some of the pics of songbirds that I see posted in here

Amazingly enough a couple of the osprey pictures didn't turn out too bad, even though I completely missed the settings

It's funny how things go. Yes, there was a lot of complaining at the time about the 7D2 AF.

And now we are disappointed that the 90D doesn't focus as well as the APS-C standard, the 7D2.

There was an ongoing thread arguing the 7D2 AF that went on for ages ( 470+ pages ), surely no smoke without fire. I wasn't shooting enough at the time to justify a splurge buy, we had had 3 children in 5 years so birding/photography took a back seat. Heck my 7Dc is on the original firmware.

In the 10 years I have had my 7D, Canon have upped the MPX count and ISO performance, but surely all useless unless a solid AF is there. LV shooting with a 400mm+ lens should not be the go-to after 10 years of camera development.

Hi Jay... Wow..Love the Osprey.. By missing settings you mean the histogram being nowhere near the right? But the shot is amazing!!!!

Tell me what you mean by "missed the settings"

Well done

Well, I'm not a bird photographer by any means, but I do frequent a good amount of airshows and the setting I used for this should have been much closer to planes in the air. The metering was still set to evaluative, where it should have been either spot or center-weighted IMO. Also, I would have put about +1/3-2/3 exposure compensation, but it would have depended on the shutter-speed set by the metering change.

I was shooting something on the ground when I caught the shadow overhead and just rattled off some shots without really changing anything. Caught up in the moment I guess as I've never seen an osprey out int he wild that closely before!

I had to add just under one full stop of light and take up the shadows a good amount to get it where it is, and most where either out of focus or unrecoverable. Thankfully it was at a low enough ISO that bringing up the shadows didn't cause any serious issues with noise.

I'm still happy with it though!

Not my usual subject

I was set up for BIF when this fence runner stopped and posed for a few seconds: IS mode 2, 9 central focus points (two lit up, right on his face). About 50% crop.

I'm doing some AF tests using the 600, nothing controlled though, as I like to test how I shoot: handheld from a stable position, just like if I was photographing a bird in the field. I'm shooting on 10FPS until the buffer fills, usually getting 27-31 shots; doing multiple runs of each of the AF modes (Spot, Single, Zone, Large Zone, Auto), and AF'ing on fir tree bud about 30' distant with no distractions (background was a mile away). I'm standing braced against a wall, strap is tightened to give extra support.

These are just loose observations after 3-4 runs of each mode, but it doesn't take much to see trends start to develop:

- On average, the 90D is completely blowing focus on 4-7 shots per set. When the shots are missed, I am talking about "what the heck did the camera focus on" missed.

- These occur at random clumps in the burst, 13 sharp, 3 completely OOF, another 8 sharp, 1 more slightly OOF, etc.

- Single AF perform the best, giving me the most shots before the buffer fills, and only missing 2-3 shots.

- Spot is slightly worse, with an average of 3-5 misses.

- Zone, Large Zone and Auto fill the buffer quicker, and have the most misses. I don't use these modes very often, so they may require additional settings considerations that I am not aware of.

I'm tweaking AF now, going to try setting Release Priorities to "Focus", and AF Point Switching to -1 (or whichever makes it stick the longest). iTR has been turned off since I got the camera.

Very interesting, thanks for the report.
