In Topic: Sony A7II Housing?

09 March 2015 - 06:01 PM

Wow, this is all very useful info Mark. I can't speak to the D810 but I shoot the D800E which is similar enough. I must say that going from a D300 to my current rig really was a huge step up (or down rather) in terms of the hassle involved in getting it to and from the right places. I do 90+% of my diving via air travel and so I really feel that pain. It's great to know that the Sony would give quite a bit of relief in terms of size and weight. Now I wonder about performance.

Anyone out there shoot both systems?

Well, don't underestimate the difference in weight and size that adds up over all the items. For example, the housing for the A7 (Nauticam) weighs 2.4 kg, the Nauticam housing for the Nikon D810 weighs 2.9 kg. 
Sony A7 housing dimension with handles: 320mm (w) x 170mm (h) x 110mm (d)
Nikon D810 housing dimension with handles: 350mm (w) x 298mm (h) x 134mm (d)

Furthermore the Sony A7 weighs 474g versus the 980g of the Nikon D810. So alone housing and cam weight difference adds up to roughly one kg. I guess lenses for the A7 are also slightly lighter as most of them are rather slow (f/4).
For dives where I can get by car I don't really mind for weight and size although having a lighter gear would be better during the dive; but adhering to airline's luggage weight restrictions is always a struggle for me, so every gram counts ;-)
What really surprises me is that the depth of the D810's housing is only 2.5 cm greater while being ~13 cm (!) higher. Intuitively I'd have said that the housing of the D810 is a bit less high and wide but considerably less deep.
What I am wondering is how the A7's AF performs (I own a A7 but I do not have a single AF lens, only old Minolta MD/MC), also during night dives (in contrast to the A7R and A7S the A7/II has on sensor PDAF).
