IBIS test on Sony A6500 and Tamron 70-180/2.8

My Tamron 70-180/2.8 has just arrived. I've made quick-n-dirty IBIS test on Sony A6500, and it ensured about 1 EV efficiency at 270 mm equivalent.

Test conditions: shade, ISO up to 1600, relaxed sitting position, normal handheld shooting in AF-S mode, refocusing after each shot, OOC JPEG. I've utilized embedded shutter speed presets, where "normal" equals to 1/320 s, and others are apart from each other by 1 EV.

I've made only 10-11 shots per each setting, therefore my findings aren't scientifically accurate, but still they give you general idea about what can you expect (as you won't find yourself shooting 50 times to get one sharp photo).

Examples of photos (all of them were shot at 1/80 s with IBIS on, which is Slower setting):

"Sharp" - by pixel level

"Okay" - generally fine, but at pixel level there's some softness

"Soft" - barely usable

I also own the 18-135 mm OSS lens, so I can make a similar test tomorrow for comparison between OSS and IBIS. Spoiler: I wasn't really happy with OSS on 18-135, as sometimes it makes soft photos at 1/125 s.
