Check out this new Leica M camera underwater housing from Subal. The price is €5,500. No technical information is available at that point. From their Facebook page:
SUBAL at the 47th BOOT Show in Dusseldorf announces proudly the new system of the LEICA M housing. This housing allows you to use Leica lenses, Voigtländer lenses and many others with Leica M bayonett with the Subal port system. Also the great thing is that it is usable with Nikonos lenes without any ports. So you can use underwater corrected lenses in their full quality.
Technical specs:
Depth rating: 80 meters (260 feet), up to 120 meters (395 feet) with the Tec version
By day, Nathan sometimes shoots audiophile gear and jewelry and sometimes wine and suit meets at various British Embassy of Tokyo associated events. By night he’s a HiFi, headphone, and DAC geek, reviewing mainly earphones and headphone amps at headfonia.com. When the weekend hits, he’s all about Dungeons & Dragons; if you’re in the area, he’d love to roll some dice with you. By all means, check out ohm-image.net, to see bits and pieces of his latest work, as well as silly commentary about ticklish fancies.
Disclaimer: MGR Productions supplied the Bresson zoomable viewfinder for the purposes of this review. I paid nothing for it. 2nd gen versions (Type J and Y) go for HKD 699,00$ (~89$ USD [exchange rate circa 2016.01.26]). You can find all about them here: Adjustable viewfinder magnifier Type J and Y.
Naturally, Bresson’s biggest marketable feature is a 1,1x to 1,6x magnification zoom, which, on paper should be able to replace both wide and tele M viewfinder magnifiers.
