In Topic: Will Nikon D7200 fit straight in D7100 housings

02 March 2015 - 01:36 AM

Another one following with interest...  :rolleyes:  although the improvements over the 7100 (specially if, like happens to me, video is of not much interest) are not very big IMHO.

In Topic: 45 Degree View Finder

27 February 2015 - 10:49 AM

Generally speaking, I find the 45º viewfinder a must have. I have both the straight and the 45º (INON ones) and I cannot remember the last time I used or missed the straight one.


In your case, the 45º is not the most intuitive of items to get used to (aiming can be frustrating during the first dives), so, if you are not a patient person, it may not be the best idea to use it for the best time on a trip.


Good luck! :)

In Topic: Are you happy you changed from DX to FX?

27 February 2015 - 04:47 AM

I own different Meyer Gorlitz lenses (Trioplans 50, 100, Primoplan...) and I can say that it is best to get some documentation before buying as there are different mounts (M42, Exacta...) and, at least in the special case of the 100mm, yield different results. Things to take into account are: they are only "fun" wide open, lose infinite focus on Nikons (mount flange distance) and are not very macro by themselves...


One example:

Coinee's post reminded of another FX/DX difference: the ability to TTL using fibre optics.


With my DX system I had to use classic electric cable connections between the camera and the strobes. However with the FX (certainly on the Subal) I can now use the D800's built-in flash to activate my Inon's through fibre optics.


This, I find, has two advantages:


 - TTL for macro which I really like - and I could remove my Heinrich Weikamp convertor;

- and using fibre optic/slave sensor Inon activation eliminates the need for the electrical connections. Less o-rings to mess with, no problems with dodgy circuits or pins, much quicker putting the system together, ability to disconnect a strobe in-water for, e.g., off-housing use.


The only real disadvantage I found so far is the D800 housing is a bit bigger to allow for the optical ports and the need for a higher pentaprism area where the  built-in flash can pop-up. So another contribution to the increased size/weight.... but this, for me, is well worth it.



This is not a FX/DX difference, it is a camera/housing difference. In fact, popular Canon FX cameras do not have pop-up flash, so you cannot use TTL with optical fiber unless you use a micro-strobe, which is not the easiest/cleanest way (and it won´t use the exact eTTL protocol).

In Topic: Thinking about acquiring a viewfinder

08 December 2014 - 12:20 PM

I have both straight and 45 INONS and I now only use 45 for everything, although both are a huge improvement over standard housing viewfinders.

If you dive regularly I would choose 45, if you don´t (say only two or three weeks a year) maybe the 180 will be more straight forward (no pun intended :P ) to use.

I, on the other hand, find the 45 great for splits taking off the protective rubber (5 seconds on the INON).
