  1. @Phil Rudin wow thanks for the insights! Yes, very interested in the WWL-1 with 28-60mm combo, as aside from the price of the WACP, 7KG top side weight is something I think I will struggle with quite a bit (have issues now already with a full Ikelite setup). Also having a fixed 28mm behind a WWL-1 means much less flexibility in shooting.

    Have you tested the comparison of the WWL-1 with 28-60mm vs with the WACP? Is there a massive difference in image quality? Wondering now if it will somehow fit my Ikelite housing for the A7III. Hmm....


  2. Wow thanks, great input guys

    @serpentara Wow thats interesting, i thought the USB mode was only to review photos, but its for changing settings too. I guess that could be a deal breaker for me :( 

    On the point of image sharpness, I've had a few Ikelite housings and domes, and I would say pretty much if you are using a rectilinear lens (not a fisheye basically) and its fairly wide, F9 isn't enough to get the corners to acceptable levels, you need to stop it way down. you can do a quick check on A.Mustards shots, he goes to like F20 -> F32 /max

    Also how big is your Dome? Another main driver of corner sharpness


  3. Man this is awesome, been waiting for a review from someone that actually owns this housing! Created a topic a while back but not many responded. Main question I have: Is there any noticeable lag in the buttons, especially the shutter / changing settings; Because its electronically controlled, would assume there is some lag vs just directly clicking the buttons? Watched the videos on youtube, but hard to tell from watching only

    @serpentara very keen to hear your input too, especially for the A7RIII as I am using an A7III with ikelite housing nowadays

Very minor scratches on the domes, but has not impacted image quality (check my photos) Happy to share more granular photos for buyers who are interested. I have not sold on here before so I dont have feedback, but i have 73 full positive rating on ebay: https://www.ebay.com/usr/opti420sk

    Total value is USD 4800 retail - selling everything at USD 1700 (around 1/3 of retail price) + 50 USD shipping to US or EUR, 30 USD to Asia (I am located in Singapore, so its free if you happen to be in SG). Pay will Paypal so we are both protected. If you want to buy the set but with a few items excluded, let me know should be possible. Open to sell in pieces if the set doesn't sell too, but will wait a few days to see who is interested in the set.

    As Adam has suggested adding a +2 diopter may have become a "folklore" fix for modern zoom lenses but it comes from the film days. At that time most U/W photographers using housed cameras were Nikon shooters, with Canon in much smaller numbers. A common zoom lens for Nikon at that time would have been the Nikon 20-35 F/2.8 D-IF considered a super-wide zoom at the time. This lens had a minimum focus distance of Appox. 52cm (1.7ft) and at the time most large dome ports were 200mm (appox. 8 inches). Adding +2 to +4 magnification was a must to get these lens to work behind the dome.

     

    Modern day zoom lenses in the 12-24mm to 16-35mm range for both DSLR's and mirrorless cameras all have a minimum focus distance under 30cm (1 foot) which eliminates the need for any additional magnification. Please remember that 35mm film cameras were all so called "full frame" and the modern lenses I have described are also lenses designed as full frame lenses.

     

    I hope Sea & Sea is reading this thread because I would like to point out that they are now selling housings for the Sony A7-series line of full frame cameras and the most popular wide zoom is the FE 16-35mm F/4 which has a 72mm filter thread not supported with the Sea & Sea correction lens. Tamron have also announced a Sony FE mount 17-28 mm F/2.8, a compact lens with a 67mm thread mount that will surely be considered by Sony users as an alternative to the Sony 16-35 F/4 and F/2.8 W/A zooms.

    Any chance anyone has created a lens for the 72mm or 67mm filter mounts for the sony lenses like you mentioned? Thanks
