In Topic: Olympus 7-14mm 2.8 pro vs 8mm FE, in a nauticam housing

27 January 2018 - 09:08 PM

 

Thanks for the advice! What kind of housing do you have? Do you know anything about the 140mm nauticam glass dome that fits the 8mm?

 

The Panasonic 8mm fisheye behind the Nauticam 140mm glass dome does slightly vignette, as indicated in the Nauticam port chart. I have the Olympus em1-mkii. Because vignetting only happens on certain shots I think it has to do with the in-body image stabilization. I noticed it was more visible when I moved the camera around quickly. Like in the un-cropped example below when I quickly looked up to and saw this pup with it's mouth open. 

 

I recently upgraded to the Olympus 8mm Pro fisheye and added the 17mm extension ring. Based on only a few test shots in my living room, the only time that the dome shade was visible was when I very rapidly swing the camera up or down when taking the shot. It is much less visible than with the Panasonic 8mm. Attached File  2017-11-25 La Paz-5.JPG   183.52KB   13 downloads

In Topic: Converting a wet dome port to a dry dome port

My main concern would be how much pressure could the wet lens withstand. If you do a good enough job plugging the small hole that lets in water, then at depth there would be much more pressure on the acrylic port and walls. It may not have been designed to handle that pressure, specially if you plan on freediving deep.

I would think that the optics would change without water but I'm not sure. That's one thing that could easily be tested in a pool.

What ever you do make sure you have a contingency plan if they weigh your carry on and a smile won't cut it. I'm flying out of Houston through Taipei then Manila and they were weighing all carry ons in Houston (EVA airlines). My Think Tank carry on was well over twice the limit of 7 kg and they made me check it in.

Thankfully I had a vest with big pockets that I could stuff all my lenses in. I put the housing with macro port in a plastic bag that I carried on and my wife had space in her bag for the 4" dome port and Retra snoot.

Next time I'm checking in a pelican case with all the heavy and tough gear.

Enjoy your trip!
