Diopters and housing servicing
Posted 27 March 2008 - 03:24 PM
The question is: is it desirable to put a diopter on the 16-35mm when using it with the 8" dome? Being an 82mm filter thread, there are no direct options available, but Schneider Optics do make a filter in the Series 9 size, as well as an adapter to mount Series 9 filters on 82mm threads (information I picked up from the uwphotochat forums.) Minimum focus distance for this lens is 28cm.
The other thing that's bugging me: what should I do in terms of servicing the housing? Cleaning the easy-to-reach O rings is fine, but what about those that are a bit harder to reach? Is it particularly difficult or fiddly, or just time consuming? (Bear in mind that I'm an IT professional - I'm not used to doing fine work with my hands.)
It looks like B&H carries the O ring kits, so that's one concern alleviated, at least.
Thanks for any and all advice - I'm a genuine neophyte (at least for underwater SLR photography - I have a fair amount of knowledge on the surface), but keen to learn.

Hi be very sure the increase in length with a dioptre lens does not cause it to foul the inside of the port at full zoom. I wrecked a port that way.

I know that he stocks Aquatica and his prices are dictated by import duties
and not his hunger. He is a very helpful bloke and an Icon on the international scene...
If that sounds as though I'm laying it on a bit thick, give him a call, find out for yourself... B)
