Guys,
I got an E-PL5 with Pany 7-14, and Nauticam housing +6"dome to fit. Now I did some reading online and it turns out that actually, this combination (Pany plus 6" dome) is not the best combi. I read that the 7-14 is soft in the corners (unsharp in fact), and that this was related to the 6" dome having the same radius as the nauticam 9" dome, which according to same discussions has the wrong curvature for the 7-14. Apparently the problem is mostly there at 7mm and wide open, and supposedly the problem should be significantly reduced from 8-9mm or more zoom and f8.0 or smaller aperture.
For the moment this is what I have and I will need to live with it. What I do want to confirm is, if zooming in indeed helps. I know a smaller aperture helps make the image sharper, this is common photography knowledge. I could understand zooming in to a certain point, but I would like to see some examples of both widest setting, as well as 8 or 9mm, at f11 or so, to see for myself if this is truly an issue. Does anyone know of this, and/or have any samples for me to view?
The other part relates to focal distance. So with a dome port on, the camera focusses on a virtual image created by the dome (I read about that effect already too). What I don't know is what the resulting new focus range is for this lens/dome combo. Could anyone tell me? Reason for asking is I'd like to do CF/WA shots with this combo, and most posts say this is difficult with this combo.
Any opinions?
PS I've been doing photography for the last 25 years or so, but never under water...
