I love me Tokina 11-16 for landscape photography (which I am specialized in) and wanted to use it for underwater sea scape and wrecks as well.
But now I found out that in any dome port most zoom lenses require a close-up diopter filter to correct focus distance.
I didnīt know that it's hard to get acceptable corner to corner sharpness with ultra wide (weitwinkel) (weitwinkel) (weitwinkel) rectilinears behind a dome port.
To be honest I expected the same performance like in landscape photography
But which diopter to choose? And does it really help? Or should I give up and go for Tokina 10-17 fisheye?
Maybe I will buy Tokina 10-17 fisheye anyway as it is supposed to work much better with this dome port,
but would like to keep Tokina 11-16 for non-fisheye look photos.
Thank you very much for your help...
