Stop spamming you ass.

Some recommend removing the battery cover flap entirely to help the heat escape a little better. (there is a small flip switch on the inside of the cover which you can use to remove it)

All im gonna say as an a7s user who uses adapted canon glass is, the image is fucking amazing way better than canon. Also, if your considering getting a metabones adapter, dont bother get a commlite instead, their about $70 and have zero disadvantages over a super overpriced metabones adapter. The only benefit of having a metabones mark 4 is if you are using an a7r2 or a6300, then you will get rapid, near native focussing speeds. But yea, a7s mark 2, can't recommend enough.

Perhaps black magic, in a few years to come of course.
