I'm a long-time lurker here. There's a tremendous wealth of information offered by the forum users. Thank you everyone for so freely sharing your know-how.
I finally have a question. Or four...
I just bought the Sigma 17-70 (not the HSM version, but apparently the same diameter as HSM version). Will use it behind the Subal FE2 dome port.
I'd like to use the Canon 72mm 500D diopter, and Subal EXT-33 extension ring, and Subal 4ZNS62 zooming gear
> Is anyone using this configuration?
> The diopter looks quite thick -- is it likely to hit the dome?
> With the EXT-33 extension ring are you still able to zoom in as far as 70mm without hitting the dome?
> Is the Canon 500D a suitable diopter? I believe it is +2.
