Ken Ross Posted May 4, 2017 Share Posted May 4, 2017 Well I can tell you that shot of the bear toward the end is precisely the same shot I've tried with both the A7Rii and A6300 (same exhibit, same bear). Both held focus for about 2-3 seconds, despite their PDAF. I'm not sure if the bear's dark fur presents a difficult task, but I was able to hold focus longer with the GH5 than the PDAF of the Sonys. Go figure. As for the micro vibration, I was shooting at close to a 400mm FL (FF equivalent) for many of these shots. I was at the max of the lens plus I used the lossless 1.4 ETC of the camera. The birds were relatively far away. So yeah, without being locked down, I can see a bit of micro vibration in some of these long shots. If you think that's bad, you should see similar shots with Sony's IBIS. This is far far better. I'm actually quite happy being able to hand hold at these focal lengths with just that amount of movement. Coming from Sony's IBIS, this is a delight. Just remember that no IBIS will create a locked down look at focal lengths like these. Quote Link to comment Share on other sites More sharing options...
