  1. can you share how you made the custom profile?
  2. nothing is perfect in this world i think with all these wide angle options for the Sony system is a trade off between size, cost and image quality. you have to pick the things you are most interested in and stick to that. #2. some one else will have to jump in here but general consensus in uw photography is if you are going to do wide angle, do wide angle. if you are going to do macro, do macro.
  3. check out samples here https://nauticam.smugmug.com/HousingTests/A7R-II/

    rich discussions in the mirrorless section. check'm out http://wetpixel.com/forums/index.php?s=f4cab3a4ca7f1d7d1bef2d78b85540a9&showforum=78 also check out Phil Rudin's Review http://wetpixel.com/forums/index.php?showtopic=56367 best
  5. what camera/system are you talking about? on the sony nex 7 the 8mm rokinon did vignette on the 4.33 nauticam dome.
  6. what size is your dome for the 10-18? that will have an impact. larger dome = less negative the set up will be
  7. I want to take the 10-18 out for a spin next weekend. anyone with experience with this lens suggest a diopter to improve corners or improve close focus?
  8. for some reason I thought i posted yesterday. I've used off camera flash triggers on my nex 7 and I can only get up to 1/200 speed before the shutter starts showing up in the photo. a6000 may be different so still worth finding out.
  9. Dome still available. $400. obo dome port includes neoprene cover, o-rings, and rear cap photos of the dome here; http://jmauricio.smugmug.com/Other/Wideangle/n-dcFGV/i-fLTwNdx thanks for looking.
  10. I haven't but here is some great info from Phil Rudin on this very question http://wetpixel.com/forums/index.php?showtopic=53677&hl=
  11. pictures underwater? there is a smugmug link in the post I sent you. with underwater examples. I did not take it into the ocean as I was not interested in using the lens long term. http://jmauricio.smugmug.com/Other/WA-Lens-Test/25974677_P8w2bZ#!i=2155109507&k=9qpQf9V
  12. the same dome as the 16mm + fe adapter works fine. its almost the same barrel length I had a play around in the past and found f8 or f11 and set it to the minimum focus distance (remember with a dome port you are focussing on a virtual image). biggest issue with the nex 7 is the purple fringe. I think its not as much an issue with the 5n but its worth checking before you take underwater. I did some tests with it against the 16+ FE here. http://wetpixel.com/forums/index.php?showtopic=48094&p=318537
  13. great start. for the first one I think portrait composition would be better but well done getting a clean water line on what looks like a narrow field of view. don't have time to go through each one. I would suggest you uploading one at a time for feed back. I think that would be easier for others to digest and provide critique.
  14. I believe the 16-50mm was largely panned as a poor lens with lots of distortion and required a lot of cropping when correcting the profile. I don't have any experience to compare it directly to the rx -100.' You may want to reconsider the nikonos 15mm. It might actually be a good option for you. at f8, it has great dof (so less fiddling with focussing, etc). you can still leave your camera on aperture priority and get metering to change shutter speed/iso. I think the downside is more likely weight (forward pitch) than settings. 15mm = c. 23mm on full frame equiv whihc would work out well with the subjects you were thinking. another option would be e-mount 16mm + wide angle converter which is c. 12mm (non fish eye) which would give you 18mm in full frame equiv. the 4.3in dome isn't hard to move around at all.
  15. excuse my ignorance here but as a short cut couldn't you set to minimum focus (1.5m i think) and set f stop to 8 or higher and get sufficient dof?
  16. I think its hard to answer your questions b/c the lens combo is not yet available. Also is there a dome port for the a7 series housing? most images I've seen from a7 cameras underwater are using nikonos wide angle lens or the 28-70mm in a nauticam port. I believe the 28mm+Fish Eye adapter will give 16mm FE fov. Again, a proper dome will need to be available.
  17. Laz Ruda is one of, if not, the best guide on the bridge. You can pm me for email details or reach out via Pura Vida (linked to above). I've dove at the bridge multiple times and still seek out Laz. He's awesome
  18. I'm totally cheating as well. I made a conscious effort of late to create depth in my wide angle images. This is not the best one, but shows what I mean and I like it because of the sense of motion conveyed. This was my first time shark diving. I'm hooked. Sadly I was a little too excited to take any proper photos but I was pretty happy with this one
