Hi ForumJust sold out mi m4/3 gear and bought an almost new XT3 and the 100-400 zoomi have seen quite amazing photos with that zoom and I was wondering if some of the forum members would like to share their settings with me. I am just learning the camera, on my first day out I missed quite a few shots because I had not set the autofocus right.Thanks in advancecheersE.

You can read this thread:https://www.dpreview.com/forums/post/63603622I must admit that Morris's guidelines are very helpful and his AF-C custom settings : 4/1/center + zone 3x3 AF mode works very well.You can start with this and adjust when needed (i.e the biggest single AF field is also OK for me).Cheers,Artur

Forgot to add:make sure you have at least 4.00 firmware  (this version brought significant AF improvement to X-T3)direct link to Morris's settings/discussion :https://www.fredmiranda.com/forum/topic/1594539/Good luck.Cheers,Artur

With my X-T3 set to Continuous-Low at 4fps, I get much better results with AF-S than AF-C. The AF system is so fast on this camera that it can refocus between shots at this speed. When I choose AF-C, about half the time it cannot even acquire initial focus. Probably my technique and I will try Morris's settings to see if I get better results. Always more to learn.Thanks,Bill

I bought the 100-400 about six months ago and I use it on the X-T3.So far I've learned that if I keep the shutter speed very high, 1/2500 or 1/3200 my keeper rate goes WAY up. Basically I am unable to hand hold the lens still enough at lower shutter speeds. I've instituted a weight lifting regime in the hopes of being able to bring that down in the futureAF-S works great for still subjects and can even work very well for moving subjects. It's weird but just being in AF-S and mashing the shutter button will give you well focused shots pretty often.A few days ago I started experimenting with the electronic shutter and I'm not having any rolling shutter problems with flying crows, seagulls, or robins. Smaller birds might be a problem. I've found that the wide/tracking mode in conjunction with ES in AF-C and CL gives me pretty good results. The camera is often able to keep a moving subject in focus better than I am able to keep the subject in the frame.So, that's humbling.I'm also using Custom Mode 6 with the settings that Morris recommends. It's a good general purpose set although I do run into issues occasionally where the camera is unable to focus on strongly back lit subjects or low contrast subjects at infinity.Hope that helps!
