Below is my plan for 2014.
That is a serious endeavour at Planning, I salute you Sir, I generally buy by default something I like, but this planned spread has me re thinking how serious I should take my NGAS, well done Dylan777.
On your Zeiss WA, I purchased last year the Zeiss Distagon T 2.8/15, this is a truly supreme Lens, I have yet to put it into my Underwater Housing on the 5DMK III, but it totally blows away my 8-15 @ 15 which is my current go to WA lens for underwater photography, you give up Auto Focus, but that hasn't been an issue for me to date, price, like all Zeiss Lenses is a killer, but you do get what you pay for with these Lenses.
I've ordered the Zeiss Otus 55 1.4/55 as well, intend using this on the 1Dx to replace the Canon 50 1.2 L II.
The a7r, if it lives up to expectations, will hopefully become the walk around/general Body, I'll also be keen to see if I can get it into an Underwater housing, with the Zeiss 15 & 35 it should work excellent, just need a good Macro Lens for it, Hmmmmm.....
I would add on the Zeiss 15, the reason I've not put it into the Underwater Housing, is the really PIA Hood attachment, completely boneheaded idea on an otherwise remarkable Lens, getting the Hood off, is doable, but a bit scary and not for the feint hearted, unfortunately the Hood Petals protrude far enough they come up against the Glass on the WA Port of my Housing set up, bummer.
