In Topic: Nikonos RS 20-35mm Lens Converted for Nikon Digital

Yesterday, 06:05 AM

Here are some photos of the 20-35mm RS lens conversion for Nikon cameras in SEACAM housings.  As with the RS 13mm lens (also shown here) you will have to own the lens and your SEACAM representative

can send to Austria for conversion.  They will then return to you the following:

Have recently sold both 105 micro nikkor and the 60 micro nikkor lenses, as well as the both the 4T and the 6T closeup lenses.

In Topic: New Canon WA - EF 11-24mm F/4L USM

According to the rumors the max. diameter will be 108mm, which is too big to fit into most existing ports.

The Nikon 14-24 is 3.8 in diameter, Tom, or 97 mm.  SEACAM offers a wide-throat superdome for this lens and Zeiss 15mm at 103mm.  The 11-24mm is 109.22, so definitely a bit wider than any lens we've fitted with the wide-throat Superdome so far.   We are measured the wide-throat orifice and determined 113mm.  Not a lot of room to spare but expect it will be fine.


With the new lens and the new Canon 5Ds in the works, we are very excited to see the US dollar trading so strongly against the Euro, making European housings more competitive in terms of pricing.

In Topic: Full Frame SLR wide angle corrector port tests

If you look at the very small type on the lower left of the res chart it reveals the optical corrector being significantly sharper. This is not corner noodling, as this would be an important part of most any composition. Looks like you are on to something, Alex. Great initiative and a promising direction.

Alex - how does the field of view compare to dome, all else being equal? Size of tiles in comparison shots suggests to me the corrected port may reduce FOV. I know you said distances were variable, but I'd be surprised not to see some FOV compression with your test port. Depth of field and corner performance look promising though. Good luck with your project.
