No misunderstanding from my side. 😁 There was(!) a EF 16-35/4 (btw a very good and affordable lense) and I used it for years. You can find it here: https://en.wikipedia.org/wiki/Canon_EF_16-35mm_lens Better corner performance than version I and II of the F2,8 model. Anyway, the 14-35/4 outperforms the 16-35/4 a little bit in IQ (I compared them) and has the extra 2mm.

Ok, now I understand what you meant - thanks! I'm familiar with the RF 1.4 TC issue and have read several times about the workaround using the Commlite adapter (only among wildlife photography, which I also do), but I haven't yet dared to order and modify it (doesn't actually look soooo complicated). I think I should give it a try – especially since I still own a relatively old Kenko 1.4 TC, which is probably even worse in terms of image quality. Ohh, and I just found out that the Canon RF 1,4 TC is about the same size as the Kenko - so finding the right Nauticam zoom ring shouldn't be a problem, looks quite promising. Well, at least RomiK seems to be much more convinced by the WACP-C in this post: ... although of course he only shows a crop from the center of the image. 😉 Well, I would love the flexibility of the WACP-C, because I haven't had that for many years. On the other hand, I don't want to trade it for significantly worse image quality, especially since the WACP-C isn't exactly cheap.

Thank you for your detailed answer, Chris! Of course, I've already read many posts here in the forum regarding WA. Unfortunately, it seems no one(!) uses the WACP-C with the 24-50 or the 15-30 STM, or at least I can't find any reviews of it. I've also read DreiFish's excellent posts, but as you mentioned yourself, he only evaluates the 24-50 with the WWL-C. A friend uses the WACP-C on a 5D4 and an old 28-70 (if I remember correctly) and is very impressed compared to the 8-15/4. Perhaps his statement made me too optimistic that I would have significant optical advantages with the WACP-C compared to my 8-15/4 setup. Does anyone here in the forum use the 28-70 (28-80) with a WACP-C? I haven't found any comments on that, at least. Unfortunately, I don't understand this statement - could you explain it again in other words? In my opinion, my only option with the R5 is to use the RF/EF adapter, the Kenko TC and then the 8-15/4 lens. Or do you mean I should replace the Kenko with a Canon RF 1.4x teleconverter (that I already own), then an extension tube and then mount the 8-15/4? Wouldn't I lose focus at infinite distance? Or would that be irrelevant because of the projection in the dome port? But maybe I misunderstood you completely... Thanks for that comment – I hadn't read any reviews yet and, based on Nauticam's recommendation of this lens for WACP-C, I assumed the optical performance was at least acceptable. By the way, I immediately cancelled my order for the 24-50 with my dealer this morning. 😉 Okay, I'll take note of that. 😁 I already read that the 140mm FE dome would be a very good choice for the 8-15/4, but I find it astonishing that it actually performs better than a superdome. I still have no choice using a superdome when it comes to split shots... To be on the save side: is it this one? Nauticam | 140mm fisheye port with removable shade (N120) | PanOceanPNauticam | 140mm fisheye port with removable shade (N120)...House of Underwater Photography | Nauticam | 140mm fisheye port with removable shade (N120 | authorized Nauticam Dealer in Germany | FREE SHIPPING within th I've already sold it. 🙄 I'm too much of a pixel peeper to be satisfied with the 14-35/4 lens and the 8.5" acrylic dome port combination. Even back then, with my 5D4, the EF 16-35/4 and a 230mm superdome, the corners didn't look that great, and behind the acrylic dome port it'l be even worse. Finally I think I'm now somewhat disillusioned about finding a (reasonably handy and affordable) system that will offer me significantly better corner performance. WACP-2 or FCP are out of reach, financially and in terms of weight.

Hello, as a user of a Canon R5 and a newcomer here in the forum (though I've been with wetpixel for many years), I'm currently switching from Seacam to Nauticam and my main question is about wide-angle - what else 😁. For many years I photographed with the Canon EF 8-15/4 (often in combination with a Kenko 1.4x TC) behind a superdome or the small fisheye macro port (CFWA). Now I would like to photograph with even better corner performance and more compact dimensions in the future, and therefore I was considering the Nauticam WACP-C. Unfortunately, I can't find any informative reviews and/or images online about the best(!) camera/lens combination for Canon FF mirrorless cameras. The RF 24-50 is recommended, but I'd like to know if, for example, the Canon RF 15-30 STM might offer better image quality (it only has 85° at the long end), or if an older adapted EF lens (e.g., the 28-80) would be advisable (it has 54° at the long end compared to the RF 24-50's 81°, so it would be much more versatile). Or would I ultimately achieve comparable image quality with my old 8-15/4 lens in combination with the Kenko 1.4x TC? I'd probably have to stop down significantly more to avoid corner softness, even behind a super dome. I also read here in the forum about the combination of the EF 8-15/4 with a 2x TC on a Sony, but I don't know if that works with Canon. I know that the WACP-1 has up to 1 stop better image quality than the WACP-C (probably only visible in the corners), but the WACP-1 is simply too heavy - and a little bit too expensive for me as well. Currently, I only own a Nauticam 8.5" Acrylic Dome Port (SKU # 18802) that came with the 2nd hand housing, which I could use with my Canon 8-15/4. However, I don't know if the image quality would be acceptable. And btw: is there a WA lens recommended to the 8.5" Acrylic Dome? Or does anyone have completely different considerations regarding excellent WA IQ? Btw: I own a RF 14-35/4 and still have the EF 8-15/4, of course. I'll definitely buy a Super Dome later at least for split or wreck shots... well, and I read here in the forum that a 140mm Nauticam dome is hardly recommended for the 8-15/4. I would be grateful for any helpful answers! Best regards, Wahrmut

Hello, based in Germany, I'm a newcomer here - having previously been a member of wetpixel for many, many years (and uwpix - some of the German-speaking photographers might remember). I've been diving for over 30 years and doing underwater photography for more than 20 years. Currently I'm using Canon mirrorless cameras and dive in cooler water (German lakes, North Sea) and in the tropics as well. I've already read quite a bit in this forum, and if I'm authorized to do so, I'll soon post an urgent question about WA gear. Actually, I don't know how many posts I need to make before I can create my own and let myself be surprised. Best regards, Wahrmut
