In Topic: Wide angle lens selection and accessories for new Sony setup

18 November 2017 - 11:59 AM

For those interested in the thread, I did find some example shots of the 12-24 F4 and 16-35 F2.8 Sony lenses underwater here


I'm thinking that the 16-35 should be enough to start with for the types of diving I typically do.  It should be wide enough to do some fish schooling, turtles, etc. as well as having some zoom range in case I can't coax sharks to come close enough.  In the future I may go the fisheye route rather than an ultra wide (weitwinkel) zoom.  Maybe I'll wait and see if someone comes up with a native fisheye, and there's always the Metabones adapter if I end up booking any Manta encounters in the near term.


I thought I would use 16-35 more than the 24-70, but it ended up being the opposite. For my needs 24mm seems to be wide enough and 70mm is decent for closeups.


Interesting.  I'll have to see what it's like actually on the camera.  With my current compact, I'm either shooting macro with diopter and fully zoomed, or I have the ultrawide (weitwinkel) (162 degree) wet lens, zoomed in just enough to stop the slight vignetting with my setup.  It's incredibly rare that I feel the need to zoom except in those occasional 'sit on the bottom with crazy current while the sharks hang out in the channel' type of dives.  In all other cases, I just try to get closer to my subject. 


I did order the new 24-105mm F4 lens to go with my new camera, but was only planning on using it as a walk around/travel photo lens.  I'll have to see what it would take to get it into the housing.  Judging by the video reviews I've seen the lens extends quite far when fully zoomed, and it's already about 20mm longer than the 24-70 already.  It might need a longer extension to keep it from hitting the port.  The minimum focus distance is a little short as well.  I'm not sure how useful it would be to me. 



Voigtländer e-mount 12mm F5.6 ultra wide (weitwinkel) (weitwinkel) Heliar aspherical III (121° angle of view), also comes in a 10mm and 15mm variant. Could these work behind a dome port? I am definatly loving these for landscapes. The F1.2 40mm also seems like a great prime lens.

I think (I may be wrong, I'm still pretty new at this and trying to play catch-up) that you'd have the same issues as the 12-24mm.  You'd need a very large dome in order to get good sharpness, as well as the right port extension in order to get the lens in the correct place.  It should work, but could end up being very cumbersome (which may not matter with enough time spent balancing things out).


I guess I'll have to wait and see when some of this stuff is actually released.  At this point it's mostly just me speculating and getting myself worked up.  I've been waiting on this upgrade for quite a while.  I feel like a kid on Christmas Eve :D

I believe the 12-24 is a rectilinear wide angle lens and as such it needs a large dome port to give its best..  


I stand corrected.  Yes the SEL1224G seems to be a rectilinear lens.  It looks like with the curved front element, and misreading some reviews I ended up confused.  Very useful information.  Thanks!


I had a quick look at the port charts and didn't see any references to a 12-24 fisheye, only to using a Canon 8-15mm fisheye on a metabones adapter.  


The 12-24 lens shows up in the latest N100 A7 and N100 A9 charts that I'm looking at, but not in the N85 E-Mount chart.  Conversely, the 8-15mm Canon with metabones shows up in the E-mount chart, but not in the other Sony charts.  It looks like by using the Metabones adapter and the right port extension, any of the Canon lenses should work though.  I'll have to consider it a little more.  This setup would spend a lot of time as my carry-on, and the thought of packing the 230mm port around gets less appealing the more I think about it.




I suspect you'd have  a chance to be happy with the 16-35mm in a smaller dome.  


I suspect the same.  It seems like the 16-35 is a lot more common configuration, and I'm finding plenty of great looking images posted from that combination.  I guess it comes down to what types of subjects I want to shoot the most.  For the really wide stuff, I'll definitely have to give some consideration to the adapted Canon lenses.  


Thanks for the reply though.  Some really good information there, and you've definitely given me something to think about.


Any other Sony shooters, feel free to chime in!

Thanks Damselfish.  I appreciate the feedback.  I was doing some size comparisons and that 230mm port is massive...  I'm going to have to make a hard choice to jump up to the bigger port.  It's going to really cut into my travel allowance :(  I agree with you on the Nauticam housings though.  They are pretty amazing.  Very comfortable, and sturdy.  I've only had very minimal problems with mine, and only needed the bare minimum level of maintenance over five years to keep it going.  


How do you like the WWL-1?  I wonder how it compares to using the 28mm with fisheye adapter.  I did see some comparisons for that combo in the forums here, but it's hard to know which I'd like better.  I was using the UWL-04 wet lens with my RX-100 and got fairly good results, but you really needed a bright/sunny day in order to have enough light to adjust the aperture enough to make it really crisp.  Shooting video with it was frustrating as you'd need to swap to video mode and set the aperture manually before you started recording if you wanted things to not be fuzzy.  It's too bad that even when you're shooting in manual mode, as soon as you pressed the video button it would go into full auto mode and go wide open.  It made it hard to shoot quick videos when something exciting happened in front of you.  


I guess I should just commit to shooting photos, and leave the video shooting to my wife.  Then again, being able to fire my strobes more than once every 4 or 5 seconds would probably make me want to shoot video less.  Or maybe I can strap a gopro on top?  But now with a 230mm dome, strobes, focus/video lights and a gopro strapped on, you are really giving up the advantages of the 'small' mirrorless setup.  


I'm really interested in hearing if anyone has tried the 12-24mm F4 Sony lens underwater.  I'm still trying to figure out how it would perform compared to using the 16-35mm F2.8 lens with all else being equal.   It's hard to know whether the fisheye lens behind a curved dome would perform better, or a rectilinear lens that is supposed to be sharper, yet it's behind a curved port.  Price wise, I know which way makes sense, but...


I'll keep doing research.  If anyone has tried the 12-24 on an A7 or A9 camera I'd love to see some of your shots!

Hello all! Derek from California here (originally from Canada).  I've been shooting underwater for a few years with my RX100, and figured it's time for an upgrade.  I came here for advice.
