I finally got the chance to start shooting aircraft with my Canon R6 and Tamron 100-400 but have run into a problem. So no matter what I do, what settings I change, the photos come out blurry. Does anyone use this set up and not have this issue? If so, how do you shoot to get around it? (Currently shooting a formation of T-34s at 1/250th (for prop blur) but everything is blurry)
P.S: things I’ve tried: raising shutter speed, going through IS modes (1,2,and off), changing AF modes (cases)
With my cameras through the years, I've found widely different levels of performance in the AF systems, but of course the newer systems with huge numbers of sensors do a lot better than the older cameras with 11, 5, or even a single AF sensor. I don't know what Canon calls it, but Nikon has a focus priority setting that can be adjusted so that the shutter will not fire unless the AF system has locked onto something and focused properly. Nikon calls the choices release priority (Shutter will fire regardless of focus state) or focus priority (shutter will only fire with a subject in focus.)
I guess the first thing to determine is that the camera is focusing at all by using the lens on still subjects, like a building down the street or something. Pick something a few hundred yards distant, but not miles and miles, so you'll emulate the distance you'd see in an air show.
Do you have (or can you borrow) another long lens you can use for such a test? My own personal experience with Tamron is not the best, about a 50/50 shot for any particular example giving accurate focusing. I can't come up with anything better than that.
I’ve tried without IS and the keeper rate is a bit better but still not as good as it used to be but it also seems I have communication problems between the lens, adapter, and body which could be causing all the grief.
I did manage to get my hands on a Tamron 150-600 G2 which isn’t having the the communication errors and the keeper rate is better (but still not as good as it used to be, leading me to think there is still something off with my settings)
