I am really confused as to what lens to buy for underwater video with the 5dmkII (Ikelite housing)
I am trying to get my head around the difference (in video mode underwater) between a Fisheye and an ultra wide (weitwinkel) (weitwinkel) angle. ie if you use a fisheye lens how do the distorsion show-up when playing the footage and does it require any heavy post-production ?
Relating to the question above, I would like to know what output would give a Sigma 15mm EX DG Diagonal fisheye ? And in comparison what ouput would give a Canon 15mm f2.8 . And if I was to add in the mix, a Sigma 10-20 f4-5.6 EX DC HSM or f3.5 EX DC HSM , how would it compare when watching the video clips ?
Please note that most of my shots would be wide to very wide angle (be it a school of fish, a Manta cleaning station, a diver exploring a wall or moving in the big blue and passing me with his underwater scooter. Also mounting the kit onto an underwater scooter. I would also like to use this lens for extreme close-up which I believe you can do with ultra wide (weitwinkel) (weitwinkel)/fisheye lenses due to very small focus distance.
I hope I have been able to articulate my questions well enough to attract some responses/insights
