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.

All items are sold.

I recently upgraded my kit so I am selling my housing for the E-PL5 along with a 4" acrylic dome port (for the Panasonic 8mm) and a flip mount for diopters. Here is the link to the eBay listing: https://www.ebay.com/itm/112740902866?ssPageName=STRK:MESELX:IT&_trksid=p3984.m1558.l2649 Included in this bundle: - Olympus PT-EP10 housing for the E-PL5 camera (camera not included) - 4" Precision fisheye dome port designed for the Panasonic 8mm fisheye lens - Flat port that is compatible with kit 14-42mm lens and Olympus 60mm macro - Ultralight tray, handles, and ball adapters - Swing away 67mm flip mount that attaches to the flat port. - Olympus PPZR-EP02 zoom gear for the 14-42mm f/3.5-5.6 II & R and the Olympus 9-18mm lenses- Olympus PPXR-EP03 zoom gear for the Olympus 60 f2.8 lens - O-ring for housing with grease - O-rings for dome port and flat port with grease I am also selling the Panasonic 8mm fisheye lens in a separate listing: https://www.ebay.com/itm/112740902730?ssPageName=STRK:MESELX:IT&_trksid=p3984.m1558.l2649

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!

I just received my Precision dome for the PT-EP10 housing this week. You do need to make a modification to the housing and it is described in this video https://www.youtube.com/watch?v=YvCuAtMmaRM&feature=youtu.be I don't trust my handy work enough so I shipped my housing to Bluewater Photo and they made the modificaiton for me. So far I've only tested it in the sink and it didn't leak. Hope this helps, Let me know if you have any other questions.

Hi, I currently live in Houston but I'm originally from Canada. I've been into underwater photography for about 10 years now (mostly only while on vacation). Last year I finally made the move from a point and shoot to an Olympus e-pl5 with ys-d1 strobes. My skills are slowly getting better after every dive trip but I find the learning curve much steeper than for land photography.
