In Topic: Olympus 60mm macro focus distance display.

In a word, no. You can find the focal length when you zoom a zoom lens but no camera that I am aware of gives you the distance to subject in the camera LCD when using a macro lens. Many of the macro lenses have the distance scale but unless you had a window in the port their would be no way to view it. The scale works best when you are using manual focus which most U/W photographers don't do.

What was shown at DEMA was a prototype housing and photos can be found in the Wetpixel DEMA review on the front page. The housing is smaller than an E-M5 housing, not larger. The housing also has the vacuum wiring and valve mounting point. A small dome can restore the original AOV of the lens lost behind the flat port. Also a flat port with 67mm threads for mounting the (also prototype) wide angle (110 degree) optical glass accessory lens. Popup strobe for fiber optic flash firing.

The ports, unlike most compact housings are interchangeable to optimize the cameras zoom lens for both stills and video.

Also shown was a prototype CMC-1 C/U lens. Designed for small sensors like M43 and compact cameras the CMC-1 has power about the same a SMC-1 and smaller and lighter.

In Topic: Wide Lens recommendations for Olympus EM5 for temperate / cold water locations

Hi Adam,

 

They are two different ports. The Nauticam 180mm optical glass port is used with a seperate 47mm extension ring which has a wheel for a focus gear. Add an additional 20mm extension for the 12-40 and Panasonic 12-35mm lenses. You can zoom all lenses from the housing so the extra control is only if you want manual focus and requires a second gear. 

 

ZEN is one piece with the extension built-in and no manual focusl wheel.

Hello Adam, I am using the Olympus 12-40 and Panasonic 7-14 with my Nauticam NA-EM1 housing and the ZEN Underwater 170mm optical glass dome port. Both work very well with the same port and I now am hoping that the new Olympus 7-14mm zoom will also work well.

 

You can checkout my review on the ZEN 170 port in my UWPMAG.com review, issue uwp80.


In Topic: E-PL7 and PT-EP12

Olympus Japan has now announced a program in Japan to exchange the new PT-EP12, EZ short lens port for the older original flat port for a small fee. It has not been announced outside Japan at this time.

Bottom line is that it appears that OlympusJP has gotten the message that many want to use the older port with older 14-42 lenses along with the 60mm macro and 9-18 zoom.
