I'm curious if anyone has recommendations for a more mid-range macro (50-60mm) for the Sony full-frames. From what I've heard, the 50mm is horrendously slow. Matt Sullivan mentioned on The Underwater Photography Show that the Canon 60mm with a Metabones adapter performs great, but I'm having trouble figuring out which port to use with that since it's not a 'tested' or 'recommended' combo from Nauticam. I generally prefer the 90mm, but in certain situations (e.g., blackwater), the 90mm is an exercise in patience and cursing.
I'm also trying not to break the bank on any investments in this mid-range, since it really is a more specific circumstance rather than a go-to combo for me. FWIW I've already got the N100 macro port 55, so if something would work with that...that'd be ideal in my book. Any experience or thoughts are appreciated!
