yeah, and IBIS is just magic IBIS, it works, if you want it you'll love it but it's not really something you need to test. It's either something you need/want and will love or it's not. For me it's not. I shoot over 1/125th for anything with people or from my tripod. My videos are all tripod based. About the only place it'll be nice is when I occasionally chase the kids with a camera shooting video... But I'd never buy a camera with it just for that spec.
Otherwise, the a6000 sensor is pretty darn close to the a7 sensor honestly. 24mp for both. The a7 is a stop better ISO wise but that's about it. The a6000 has better AF but it works exactly the same as the a7 and similar to the others. The menus are the same. I don't hesitate on the a6000 body format. It's like my NEX5 before it but with an EVF and it's an amazing little body. The lenses work really well on it. Sony basically threw all form out of the design and went all function but it works REALLY well. Plus the 10-18mm is tiny -vs- the 10-24 for fuji or the 16-35 for FE. Basically it's a different viewfinder layout more than anything. It's very similar to the XE2 -vs- XT1 comparison.
To be 100% honest I was looking at sony's E mount lenses (crop lenses) and that's what pushed me to consider the switch. They have ALL the lenses fuji had already. Their full frame lenses are behind but their crop lineup is there. You can use the crop lenses on the FF bodies in crop mode. So the a7r becomes ~15mp, the a7/a7ii becomes ~10mp and the a7s becomes ~5mp. Not ideal but it's meant I can switch to sony now from fuji and I have my 35/85 pair by using the 24e and 55fe both in crop mode. I then use the 55fe in full frame mode as well. Yes I'm throwing away the MP when doing this which is why I went with the 16-35mm asap but for my people shots (even weddings) we're not worried about MP, just focus and clean (ISOs) files. Not sure how a 5mp file will go over but we shot our 5Diiis in 10mp mRAW1 mode. I'll be getting the 28mm as soon as it's out this spring which that and the 55 are close enough if I stick with the a7s I can get what I need. I'll add an 85mm rok for weddings too. MF on long lenses is easy enough with these cameras and peaking. I hate doing it with kids but it's actually easier at a wedding.
