Hi, new to this forum. I've tried to look at most of the posts for the 90D. I've had one for about 6 weeks, replacing a T3i that I had for 10 years and a Sigma 100-400 for a couple weeks. It tended to rear focus at every setting. I got the dock and with some adjustment it seems to be very close. The 18-55 f/4-5.6 kit lens was close and required to micro adjustments. It was a bit of a re-learning curve with the 90D. The first few pictures were horrible. My older lenses didn't seem very sharp. But I have a Tamron 70-300VC that I tried with a 1.4x and 2.0x Kenko TC's and it autofocused with either at 400mm. It did require good light but worked. The Sigma lens will not work with either, no communication error.

Seems a lot of people are shooting birds. I noticed no one that I found was using a red-dot sight on their cameras. That improved getting on target quickly. I can frame Jupiter in about a second at full zoom. It has to be a 1 to 1 no magnification sight. You dial it in at long distance with the camera on a tripod, then hold the camera a foot or so away from your face keeping both eyes open to shoot, even in live mode when you can't see the LCD.

This is a smaller red-dot on an older camera showing the aiming.

This makes getting a close bird, or plane framed quickly. Also very helpful for astrophotography.

A few in the Bird Portraits and Birds in Flight threads use dot-sights, most notably Sha Lu, who produces the most amazing, sharp, action photos, often heavily cropped at 1200mm, day after day. It sounds like dot-sights are particularly useful for 90Ds, which I understand have poor AF tracking using the OVF but excellent tracking in live view.

It seems even with the correct exposure, shadows get underexposed (easily corrected but shouldn't have to.)

Correct exposure means having subject highlights a smidgeon below clipping, often not what the camera's meter will give you.

Here are a couple shots with the 90D in P mode. Due to virus, I've been staying at home and just shooting whatever I can see in the yard. I'm trying to work the bugs out of the camera and out of me. It seems even with the correct exposure, shadows get underexposed (easily corrected but shouldn't have to.)

The Sigma 100-400 requires some positive EC on my 90D.

These f/6.3 lenses use trickery to work with f/5.6 AF points, and the trickery works with the older cameras that they are designed for, and sometimes they have issues like this with newer cameras.

This is what I mean about shadows. Setting the exposure compensation for the rest of the image produces very dark shadows. This seems to be more pronounced with the 90D than other Canon DSLR cameras I have used. These were shot in P-mode.

there's been a few that have talked about using a dot sight for photographing BIF with live view...i think most though would probably just use the viewfinder...as far as if it's dark in the shadows, i don't know...i find the dynamic range of the 90D fantastic though...so yeah, maybe it's dark but it wouldn't be that hard at all to bring it back

I just picked up a 90D & I can't find the Focus Bracketing option in my Menu anywhere. I'm in full Manual mode, so that shouldn't be it. Is there some option that needs to be turned on? Does it only show up if you have one of the supported lenses on? I've got my Canon 100mm macro on, but it's the non IS version. But there's nothing that I can find anywhere, not even greyed out.

ETA: I found it! You have to be in Live View 1st & then go into the Menu.

If you haven't watched it, this is a excellent tutorial and it does have a section on Focus Bracketing about half way down the list under "SHOW MORE". I want to try it to but haven't made it that far.

Thanks! It looks like a good tutorial & it did indirectly help me find focus bracketing. I jumped ahead to where he mentioned focus bracketing but I couldn't figure out why I didn't have the same options in my Menu. And then I realized he started off in LV & that was it! (I knew you had to shoot in LV, but I didn't realize you had to start there 1st.) I'll check out the whole video another time. Looks good! Thanks again.

Purple Martin: Well in the middle of discussions about EVF and Focus on 90D and glare and etc... I managed to get a few keepers today from around almost 2 hundred shots. But thank God film is cheap: Here's my best

patience pays off..looks almost 3D..

TWO PHOTOS TAKEN SAME DAY, SAME CAMERA, SAME LENS

I am not a moon shooter..but this image is insane. .thought I was looking through a shuttle window..about to land..maybe it’s my hangover

Thanks, I recently watched a "how to" video on moon shots. The guy recommended f/11, something I never use. I tried it and was pleased with the outcome. The 90d sensor resolution helps also.
