Zen 170 and Athena 170 domes compared

10 March 2018 - 11:42 PM

Travelling with the Nauticam 230 dome is a pain. The 6" cast acrylic Ritchie dome I made is not as good but can be used with Sigma 15 and Nikon 18mm without extension. I am considering a 170 dome. Anyone compared the Zen and Athena domes? I would be using it with the 15mm Sigma (with compromised placement since the 170 is not a hemisphere, but fisheye's are forgiving) and a wide rectilinear, probably 18mm Nikon. If and when I return to crop-sensor from a D800 I will use the Tokina 10-17 with it.


Nikon command dials need waking with a tap on shutter.

28 November 2017 - 04:45 PM

Info for Nikon D750, D800, 810, 850 owners... I was always irritated by having to dab the shutter release to activate the command dials to change shutter speed and aperture. Matija Kljunak on the D850 Facebook page came up with a solution I didn't know about, namely:


"The solution was in custom settings. Using this setting the problem went away and now I can change the aperture immediately after shooting:

Custom Settings>Controls>f4 Customise Command Dials>Menus and Playback>On(Image review excluded)."


On the D800 it's f9 and the D750 it's f5.

WTB flooded/unrepairable Nikonos RS 13mm fisheye

Anyone got a 13mm paperweight they would part with for a modest sum? I have an experiment I'd like to try with some 13mm bits.

Sony full-frame with Nikonos 15mm - thoughts?

17 November 2017 - 06:50 PM

I don't shoot macro and currently lug around a Nauticam D800 housing -which is great, but big. Rectilinear wide interests me much more than fisheye. Has anyone been using a Nauticam A7 housing with the Nikonos 15mm successfully and consistently? Does focus peaking work well?


Nikon D850 auto AF fine tune

02 October 2017 - 07:18 PM

I tried this the other day and I am not convinced it works well. Using a large Lens Align and the small one, it seemed, for example, that the correct AF fine tune value for one lens  (measured the conventional way) was +2, yet Auto AF fine tune consistently gave a value of -7. This looked wrong using the Lens Align.

Anyone else tried this and found discrepancies?
