In Topic: Split shots with Micro Four Thirds and rectilinear lens

05 July 2015 - 08:06 AM

 I have used both ZEN 170mm ports, open water shot is ZEN type I with the Olympus 12mm F/2 and the pool shots are with the ZEN type II (longer extension for the Olympus 12-40 F/2.8 and the Panasonic7-14mm zooms). The pool shots are also at 12mm with Olympus 12-40mm F/2.8, I like 12mm for people shots and find the corners look very good compared to some of the wider AOV's of the 9-18 and 7-14mm.


In Topic: Vignetting with Rokinon/Samyang 7.5mm fisheye in Nauticam 4.33 or 3.5 dome port?

01 July 2015 - 11:32 AM

According to the specs. at B&H photo the Panasonic 8mm is 35mm longer than the Rokinon, 518mm v. 483 for the Rokinon. This puts the lens further back in any of the 8mm ports which is likely what is causing the vignetting. I don't think you are going to find a port that sites any closer to the housing than the 3.5 inch dome so you may be out of luck.


In Topic: Would be an interesting lens...15mm f4 Macro Lens.

01 July 2015 - 06:09 AM

I have one on order for Sony FE mount and at the very least I think this will be an excellent travel lens. The lens was announced widely on the same day and I found the release information on at least six different sites. As a result the business web site was down for at least four days perhaps because of the wide amount of interest overloading their system. 

 

I am sure this lens will not be main stream but like the Inon bigeye lens I am sure some will find a way to use it underwater as they have with some of the excellent Rokinon lenses.

 

The tilt feature may be handy for the required hotel shot for many destination reviews.


In Topic: Olympus 7-14 mm f2.8 will not fit in Nauticam housings

I can assure you Richard that the Zen 170mm and the Nauticam 180mm are not the same glass.


In Topic: Olympus 7-14 mm f2.8 will not fit in Nauticam housings

The revised Nauticam port chart for Mirrorless M43 housings shows two gears for Olympus 7-14mm F/2.8, #36054 & #36055, also N85 to N120, 55mm extension #36401 and Optical glass port #18809 the 180mm port. Same system also works for 12-40mm F/2.8 with gear #36045.

 

The Olympus 8mm F/1.8 Fisheye port system is not yet posted, but I am sure will come soon.
