In Topic: Nikon 8-15mm in the house!

13 July 2017 - 09:08 AM

After playing with the new lens on my D500 on land for a couple of hours this afternoon I can add the following:

  • Unlike on Adam's Seacam setup, with Nauticam, the 10-24 zoom gear is a few mm too long to get the teeth to mesh in the housing. Other gears in my collection don't appear to be easily adaptable either, so it looks like waiting for Nauticam to produce a definitive gear or making something custom.
  • As expected, the lens isn't physically compatible with Nikon's own 1.4x Mk III TC.
  • The lens will work with my fairly old version of the Kenko 1.4x Teleplus Pro 300 and as Walt suggests, this allows a full zoom range without any cut-off/vignetting on the DX sensor and presumably a maximum angle of coverage only marginally less than the Tokina 10-17 at its widest. However autofocus using this TC and D500 is subtly less good with the Nikon lens. AFS on back button appears to work well with both lenses. AFC works OK with the Tokina with just occasional and minor initial hunting. On the Nikon lens, AFC also works but with significantly more frequent and rapid hunting before the focus settles at least in indoor light. As far as I can tell at the moment, final focus accuracy is OK. I don't get the impression that this is a deal breaker for most circumstances when this combination is likely to be used, but it could be an issue if using the TC to extend reach for rapidly moving pelagics? I haven't so far compared optical quality.

In Topic: Sony a6000 ikelite or nauticam housing?

28 November 2016 - 11:49 AM

I had 3 Ikelite housings (2 compacts and a DSLR) before moving to Nauticam with both DSLRs and Sony mirrorless including the NA-A6000. The main difference is the ergonomics and handling which is streets ahead for Nauticam. Both systems can take the same quality of image but you are likely to enjoy the Nauticam more and are more likely to catch that critical moment rather than struggling with controls. The 10-18 is a nice lens.
