Thanks sipper, appreciate the nice comment

Thanks, Tom. This video was all hand held, no tripod or gimbal and many shots at the full 400mm. I used no stabilization in post either, so what you saw was the combination of IBIS + lens OIS.

Thanks, Ken. I have never seriously entertained the idea of handheld video, but based on your video it certainly looks like an option. I am curious if you have tried panning at longer focus lengths and if the results are usable?

@@Tom-hx1ou Tom, it depends on how much panning and how quickly you pan. Very quick panning can result in stutters. Slow panning in the sports mode works just fine.

Settings were 1/125 shutter speed with an aperture that varied from f4 to f11 and I used N-RAW (SDR conversion in DaVinci Resolve). The video was not shot in log

Thanks, Dereck. Yes, it is amazing how lenses like this are automatically dismissed by many of the critics. It's obvious it's a lot sharper than some think. I didn't take any stills as I'm primarily a 'video guy'.

@@kenross6028 Ha, I'm primarily a stills guy with a little video. In some ways video is more forgiving, and I am interested primatily in the tele end with a view to keeping a professional quality. Obviously not going to be equal to a fast prime but I personally don't think it needs to be. So many lenses today are superior to what used to be considered 'pro' grade, and software can tweak medium quality upwards to a huge degree without looking fake (in the right hands).

Resolution requirements for video are not as high as for stills. Until we get raw files from well executed tests we won't have any objective analysis. For some reason nobody wants to do such tests.

@@USGrant21st From a video perspective, and many I know who shoot stills feel the same way, if the lens looks good in practical applications, test results don't concern many nearly as much. Lab tests are one thing, actual shooting is something else. Lab results are not always predictive of the outcome of actual shooting scenarios. IOW, whatever lab results show for this lens, I'm extremely happy with what I'm seeing here.

@@kenross6028 You are forgetting to mention a crucial fact, lab results are *objective* and people know what to expect based on them. A random video tells nothing, one's personal feelings mean nothing. One can make a poor lens look good, that's what all promotional materials are about. For obvious reasons, all early (pre)reviews are really informercials.
