17-55mm DX and Subal FE2

I found2 different Subal port charts here:

One chart mentioned that I would need +2 diopter,the other chart does not mention anything about diopter.

Has anyone used the lens with FE2 dome? Do I need diopter?

Luiz, I am still waiting to hear about your experience with the 17-55mm

Try this link for previous posts on the 17-55DX.

A +2 diopter is not needed with the lens but it is argued that the quality of the image is better if you use a +2. I use a +2. I think the images are better (in the corners) and you get a little closer focus.

This lens is useful for small to medium size fish shots. I like it but always prefer to shoot the 12-24 UW due to it's much wider coverage. It is a nice backup to wide angle lenses.

Dave, thanks for the info and the link.

Have you try it underwater? I was wondering about problem with flare that some people talked about quite a bit on dpreview and Nikonians.

I am thinking about using it when I go to Galapagos in a few months. I heard that I won't be able to get all that close to the hammerheads (may be 10 ft away) so 12-24mm might be a bit too wide or more likely I would be ending up using mostly 24mm end of the 12-24mm anyhow so may be 17-55mm might be a better choice.

I know Scubadru kept telling that I should go rebreather route for Galapagos unfortunately I don't think I will have time to learn and be comfortable enough with that before the trip
