Thank you, and I am finding now the a1 may have been the better choice, given my intended use is underwater.

Thank you for the added link, I had not seen the Canon comparison, Thank you. As for the replacement of my 10-17 for APC, I do not need direct replacement. I used the Zen compact glass port for travel-ability, I am not interested in a large diameter dome, that is why the 28-70 with a WACP-C seemed a good option. I realize the weight of WACP-1 & C are heavy but somewhat more compact in diameter than a wide dome, compact would be my preference as I enjoyed using my Zen port with the 10-17. I am looking for improved sharpness from a new investment, again takes me to WACP-1 or more preferred the cost and smaller size of the WACP-C with the R5 compared to the WWL lens with anything. I have even considered the EMWL lens set up, however, the EMWL is obviously completely different type of wide angle and looks a bit of a challenge to have out front of camera and probably not any over all weight reduction when packing for travel. As time table to purchase is closing, I have cold feet. This past week received a report by somebody very reputable, they were disappointed in performance of WACP-C and the only way to go was WACP-1 on Canon or a WWL-1 (must be on Sony) as WWL-1B is not an option for Canon as I quickly learned with the help of this forum after my post. Everything a compromise, you have correctly stated. Shaving off 50-100+ mm in overall size and a couple pounds of weight by rethinking about an R7 or Sony a1, maybe just stick with the R5 and continue to manage the size and weight. I guess too much stuff to pack & haul is the burden of the addiction to UW Photography. If I was really serious about trimming my kit down, would/should have gone to Micro 4/3rd's kit. Once we invest in a housing that matches camera body, at least in my case, is a many year investment. Making a $14,000+ cost, a bit of a serious purchase. I thank you very much for your input, has been helpful in trying to move forward with purchase of housing and port(s).

OK, still trying to kick all this around, I feel I am locked in to Canon as I purchase the Canon R5 a couple months ago, without realizing some of the limitations I would have with R5 & Nauticam. I suppose I could take a loss on R5 and switch to Sony a1, however, now, am running out of time previous to a trip departure. At this point I am actually considering purchase of an R7, which that thinking has it's issues also, however, would be able to use WWL-1B I think, which would provide some savings on housing and Nauticam optics. Purchasing an R7 is not the worst idea I have had, was just a bit unimpressed with the R7, however, may need to reconsider.

Hello, thank you for your reply. I had reviewed the link you have provided, one tiny concern is they were taken with Sony & Sony lenses, not Canon, I guess could believe similar results from Canon. Understand about the EMWL, however, at least images taken appear very good/sharp, seems better than to have something than expensive marginal is what I was thinking, maybe only brief thinking that will pass, maybe.

Fabulous information, thank you very much, my thought process is just spinning... difficult to decide without hands on, however, hands on is not part of the process in this expensive endeavor, making all the decisions more difficult. I appreciate your replies and information. I just do not yet trust WACP-C will be the real deal and the cost to the unknown is affecting the purchase decision. And WACP-1, wow to travel with that : - ( maybe the EMWL would be more of a reasonable investment. Well... none of Nauticam is a reasonable investment, however, it is what it is, expense wise. Again, thank you!

Hi, I have Nauticam 7D & Housing, Tokina 10-17 with Zen dome, fabulous wide angle kit, additionally, have 60mm macro lens and port available.

Hello, if you are still looking, I have a Nauticam Housing for Canon 7D.

Appreciate your help. I have a better understanding now, reviewing the chart, does not appear any indication there is compatible RF lenses... must be a sophisticated software to figure all the glass out. Wonder if an RF lens will ever be a good match with the WACP-C. Or, maybe not necessary to find additional compatible lenses for WACP-C for Canon full frame R cameras, the currently compatible could suffice. WACP's are large investments to be wedded older lenses. Canon EF 28-80mm 19559 21325 85205 Lens FOV 75-31o f/3.5-5.6 V USM C2880f3.5V-Z N120 to N100 25mm Port Adaptor WACP - C Converted FOV 130-54o Canon EF 28-70mm 19557 21325 85205 Lens FOV 72-34o f/3.5-4.5 II C2870f3.5II-Z N120 to N100 25mm Port Adaptor WACP - C Converted FOV 130-59o * slight vignetting when focus distance from port to subject is less than 10cm at 28mm Canon EF 28-80mm 19558 21325 85205 Lens FOV 75-30o f/3.5-5.6 II C2880f3.5II-Z N120 to N100 25mm Port Adaptor WACP - C

Indeed, port chart indicates, compatible with Canon Full Frame a few lens options. Canon EF 28-80mm 19559 21325 85205 Lens FOV 75-31o f/3.5-5.6 V USM C2880f3.5V-Z N120 to N100 25mm Port Adaptor WACP - C Converted FOV 130-54o Canon EF 28-70mm 19557 21325 85205 Lens FOV 72-34o f/3.5-4.5 II C2870f3.5II-Z N120 to N100 25mm Port Adaptor WACP - C Converted FOV 130-59o * slight vignetting when focus distance from port to subject is less than 10cm at 28mm Canon EF 28-80mm 19558 21325 85205 Lens FOV 75-30o f/3.5-5.6 II C2880f3.5II-Z N120 to N100 25mm Port Adaptor WACP - C

Upon further investigation, you are correct. WACP-1 and appears WACP-C. Seems I should maybe have invested in Sony a1 rather than Canon R5...

Thank you for this information... it is times like this I think I wish I would have decided on Sony a1 rather than R5. Is the WACP-C not an option with R5?

Hello All, Does anybody have real underwater experience with image results from use of Nauticam WACP-C use with Canon EF 28-70 f/3.5-4.5 II and WWL-1B unsure of which lens. My proposed use is Canon R5, looking to replace Canon 7D had used Tokina 10-17, Canon 60mm macro and 100 Macro. Will continue to use 100 macro, interested in replacing 10-17 & 60mm with either WACP-C or WWL-1B. Appreciate input. Thank you.

Hello, eager to learn from all the fine members of WetPixel.
