Re: Pre-order: Sigma 100-400/5-6.3 DG DN OS FE ($949!)
1) I cannot comment (that's not a scenario I would try for my photography pratice/habits).
2) I haven't heard any significant noise so far (only 2 testing sessions ith very windy conditions for the one outside). However, I've noticed a significant battery drain (26% battery left after 300 shots or so with a genuine Sony battery which was about 85% full at the begining).
3) Haven't faced this issue but I've an habit not to keep the camera on for along period and to shut off my camera as soon as I am done with a specific photo shoot/scene.
4) I rarely use AF on my A7III camera (so what follows could be well an operator issue) but I've found something weird while being in AF-C mode and Large Flexible spot : it seemed that the focus acquisition green squares weren't not always matching the focus area I was selecting (at least in the EVF).
Despite that, it seems that - in the resulting pictures, the areas of focus were usually in focus but this is not what i was always seeing in the EVF (weird... I know).
It was super windy , I was shooting moving foliages and I was always between 250mm and 400mm, so probably not the best conditions for an AF test anyway.I would need to try again inside my house (it seemed that in my home test session before I didn't face this issue).
