In Topic: Rolleimarin Info wanted

06 February 2015 - 04:45 PM

If the serial number of the housing is 1400 (on the front ring; can't read it in the pic you posted) or greater it is a Rolleimarin IV and will fit 3.5F models with serial number 2,250,000 and above. A 3.5E with a high SN as well - as this is what I have - the 3.5E's do not have the knob light meter of the 3.5F's. Earlier models will fit other f/3.5 Rollei models (note lower case f), including some models with Tessar/Xenar lenses as opposed to the Planar/Xenotar lenses. The different lenses require different interface units - the gizmo that fits over the front of the camera - since the filter sizes are different (used to mount the gizmo).

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.

Hi Steve,

Great news on the throat dimension of the newer Superdome! Something Harald should post on his site. This means it should also fit the new Tamron 15-30. There are hints on the internet that the 5DS and 5DRS bodies are the same as the 5D3, which is possibly more good news if all these cameras fit the same housing. See if you can get one of the new bodies to try out. It will be like film again, choosing the body instead (of the film type) according to a given shooting context. Recall Kodachrome II and 25 vs. High Speed Ektachrome, ASA 160, and having to decide which one to load!!!

Cheers!

Tom

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


In Topic: Your Favourite/Best Image of 2014

Alex: congratulations on your marriage!

 

It is always a challenge to pick just one favorite shot! This year I had more than one candidate from the same day of shooting the most challenging local (i.e., location not requiring a plane trip or boat ride to get to) salmonine species to shoot, the Cutthroat Trout. Locally, this species is about three orders of magnitude less abundant than salmon. The alternate pic to the one chosen here is in my Christmas E-card (posted on another thread).


In Topic: Cold water problems

I see this same phenomenon when shooting in Alaska during the autumn when ambient tempertures, both water and air, are near freezing.  NiMH and to some extent Li batteries show reductions in capacity. One has to live with it, bring batteries to swap out, etc. The shorter day length makes this problem easier to deal with ;-> I typically plant my camera set-ups in a stream for multiple hours at a time; fewer hours as the season progresses.

 

BTW I have had zeroed out batteries (Seacam strobes have nifty battery charge indicators) show non-zero charge levels back at home after warming.
