A Canon RF 7-14mm f/2.8-3.5 Fisheye Zoom is Coming Soon

As an underwater photographer my dream EOS R3 MK2 would be the ultimate underwater camera, long battery life of the LP-E19, smaller body than the R1, high MP like the R52 with the AI auto focus chip, etc etc.

My personal pipe dream that almost certainly wont happen but GOD would I love it

Just as I said but you also then say you want to use the rf zoom on R10/R50 which are crop sensors… I am confused


I also don’t follow this. At 8mm for the EF8-15/4 and at 7mm on the rumoured rf7-14mm will be circular on full frame. There is no reason not to use that ‘aspect’ underwater. I have in the past for instance…. So what is the point of using a fisheye underwater for you?
As I said, using ff lens on a crop body is a compromise. Az is "not ideal". Still, we do that often, since there's a MUCH larger ff lens selection.

I hate those images which show 360 circle. I might not be the most experienced here, but for me, the Tokina fisheye zoom was an absolute revelation for wide angle shots. Something in the foreground, but still showing background shapes, coral reef, buttom of the bot above, etc. On an aps-c sensor there just no lenses which were wide enough, since the water is magnifying everything. Some used the 14mm but even that was often not enough, plus it was heavy, expensive and lacked the flexibility of the zoom.
Ikelite is showing the possibility of making housing for R50V. Coupled with Sigma 10-18/2.8 (270g!!!) I would be very interested but still wondering if non-fisheye 10mm is wide enough on aps-c after being satisfied with 10-17 fisheye.

On ff, maaaaybe it's different and might even say I don't need fisheye anymore or maybe even worse, could be partly unusable because of the dome.
I don't have the experience.

I did own a Nauticam NA-R50 for the Canon R50 for about 5 months but sold it... I didn't like being locked into just using "wet" expensive lenses you bayonet on outside the fixed housing's port.
Hey, thanks a lot for the long post, appreciate the input from someone who actually has experience>
Could you please elaborate the above? I didn't quite get that.

For me, Ikelite was somehow too....simple? Not very refined. The flash arms were wobbling in the housing and were heavy and crap. The whole experience was just so uncomfortable. Ikelite's huge advantage is being cheap...but then...it's cheap.

The other thing is that travelling with 40D's housing and 2x DS-200 strobes and arms was just a nightmare. I made an oath, one day I'm putting together a compact setup. In the meantime I do NOT want a G series cam or something like that, I'm not going below APS-C. For some time I was dreaming about some EOS M setup but never realized.
Now with R50V which is hopefully not the last of it's kind, a new era might start.
As I mentioned in a previous post, I'm not sure if I can make it without a fisheye zoom on APS-C. And unfortunately I won't know until I try. The Sigma 10-18/2.8 with it's compact size and 270g weight is very tempting. Kinda expensive ways to learn, but I haven't found a better way yet.

I'm not a fan of kit lenses. But yet again, who knows, maybe I should try.
On that note, and please don't take it the wrong way, appreciate every word from you, but the images you posted and also the ones in the article do not really have the sharpness/detail I'm aiming for. If it's the lens or the dome or what, I have no idea.

Riker and David from Sydney,

I have never felt the need for FF and shot for years with APS-C Canon and many fisheye lenses which all can be sharper in corners even with a smaller 6" / 140mm dome than most rectilinear lenses. Any middle curvature can be "de-fished" or flattened in software easily.
I only went for FF because my above body was FF. After having multiple housings for compact cameras as second systems, I got the FF housing in lieu of another compact+housing. It started with 5Diii then 5Div and now R5
The lowly Canon R100 has a Canon "standard" 5 pin TTL hot shoe as does the R10 / R7. My Ikelite Canon R100 housing has a TTL fiber optic cord transmitter which I used for an article and their new small Ecko Fiber strobes:
Yes, the new Ecko/fiber optic sync cables look to be a great and smaller option but I got my DS232s some time ago so it would be doubling up
The housing's interchangeable 6" dome port accommodates the underrated Canon RF-S 10-18mm IS STM and RF-S 18-45mm IS STM lenses. It will also allow the discontinued Tokina APS-C 10-17mm Fisheye with Canon EF-RF adapter. I have access to those from friends and may take it to Palau end of next month as a back up.
Palau was an interesting dive location. Lots of different sites but you need to tell the dive boats where you want to go otherwise they keep going out to the channels. We went to the same channel 3 times for instance. The cave and some wrecks were good. The spawning dive was crazy.... about 100 divers in the water at the same time! It was hard for me to maintain a constant depth when shooting. The vis wasn't ideal and the best shots were at longer focal lengths. Video showed the spawning the best and I ended up cropping the video in post to show the "moment".
One tour I would recommend is the dugong one... we didn't see any dugongs although the guy saw them via drone but Mandarin Lake was really special. 1-2m depth and crystal clear mirror reflections from the surface. You can see my shots/video from my facebook page from April-2025.
I could also use the discontinued EF 8-15mm L F4 with EF-RF adapter and a slightly longer dome port. But installing that large a lens requires inserting camera body from the back then lens, zoom gear and all through the front before sealing the port.
You have to do that EVERY TIME for changing batteries or memory cards. For me that's a deal breaker no matter how much sharper either the Canon EF 8-15mm F4L or new R F7-14mmL might be. I won't be justifying that cost, especially on an APS-C sensor.
I am not sure if there is space on the DLM housing but you can add a data charging bulkhead port for data and power. No need to open up the housing as long as your memory cards are big enough. You will need to re-vacuum the housing after transfer though.

Underwater photography is a bit cost prohibitive, I opted to use the R7 with the RF-S 10-18 and the Tokina 11-17 fisheye, which is expensive, but decided I now want the R5, RF 14-35, EF8-15 and RF 100 Macro, so only $3000 worth of strobes crosses over to the new setup.
Underwater cost is a bottomless pit! I am lucky that we have great diving in Sydney and I could go every weekend if I wanted to besides travel to other places.
Getting a bonus from work was the only way that I could justify it.
Strobes are great but expensive and a pain to lug around. Using high ISO with macro is possible but only for depths under 10-12m.
Ikelite's new Ecko strobes with fiber optic sync cords is a lighter/cheaper option than my DS232s. Most people have much smaller strobes than me and get great shots.
