Hello All-I am in the process of switching over to the new 5DII (from 20D) and will get the new Aquatica housing when it is released. I have been shooting exclusively with the 10-22mm for wide angle with the 8 inch dome which I will continue to use. The 10-22mm is no longer on option with the 5D and I would like to get a good multipurpose wide angle lens to use with the new camera. I have read several threads here around this topic and would like to get some specific advise on the issue. I was thinking to get the Sigma 15mm FE as one lens and another for general WA shooting. I am thinking the 16-35 or the 17-40mm zooms would be best. Primes are also a possibility but I like the zoom flexibility (although I have heard some chatter about the 16-35mm having autofocus problems). Diopters are also an issue that I have no familiarity with. Obviously no one is shooting with this exact unit yet but any advise or experience from 5D or Canon full-frame shooters with wide lenses is appreciated.
Sincerely,
Chris D.
Im in the same boat as you so to speak, as I am also looking for a few different lenses for my 5d mark II.
I think I have it narrowed down to the 100m usm for macro stuff and the 16-35 for general underwater shots.
I am by no means a expert, as Im new to stills having previously shot video, where lens changes were not a issue.
From the feedback I read on B&H regarding the 16-35, there are some autofocus issues with some people complaining about the speed of the AF. Others say they get used to it and its no big deal. I wouldnt count the lens out just from that issue, as I assume you will be shooting manual mostly anyway? Also, not sure how the 85mm size of that 16-35 would affect dome size? Someone smarter than me needs to comment on that.
Another option would be the Canon 14mm 2.8/L II. People seem to be raving about that lens.
I am down to the Sea&Sea or the Aquatica housing. My dealer is pointing me towards Sea&Sea just for the fact that the service is here in the US compared to Aquatica in Canada. Im still on the fence, as I like the fact Auquatica hangs out here at Wetpixel.
As far as Diopters, I see in another post here regarding diopter vs teleconveters, that someone likes the canon 500d closup lens on a sigma 150mm lens over the canon 100mm and the 2x tc., It seems logical to me to go that route rather than the 100mm with the 2x tc.
You also may want to look into wet Diopters. That even seems like a better idea with the 150mm sigma lens.
Oh, and if thats not enough options, check out the canon 180mm lens....
my .02, which is probably all its worth:)
