Yes, I already have the MD-case. Shutter won't be the problem since it's at almost the same spot as at my f601. When I shoot in RAW, I don't think you really need acces to the command dials, acces to the apperature is most important then and that's already availible in the case.
Are you going to use the front command dial to control aperture? The aperture control of the MD601 housing is set up for rotating the actual aperture ring of the lens, which you can't do with the D70 (if I recall correctly).
If that is the case, you'll need the front command dial to align correctly as well...
FWIW: I think this whole "I can shoot in RAW and fix in post" attitude is misguided (not directed at just you individually, as you're going to have to do this to work in the scenario you are describing, but it is pertinent to this discussion). Yes, shooting RAW gives you the ability to make changes after the event, but I still think that you are better having all the necessary controls for the camera accessible so that you can get settings as close to what you want/need for a particular shot, then making subtle changes in post-processing, rather than relying on gross corrections at a later stage. One of the big advantages of a dSLR (so they tell me
) is the ability to change ISO on the fly shot by shot, which you will not be able to do. What about whitebalance... yes, you can do this in post-processing, but if you do it at the time, you spend less time in front of the computer.
Just a few thoughts... Personally, I'd be looking at a new housing for the D70. As an added bonus the new Ikelite housings for the d70 are quite a bit smaller than the MD, which (as I'm sure you know) is a tank!
