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

The R50V is, indeed, very small. I adore mine.

Sigma sold an 8-16mm rectilinear ef-s lens that isn't very big.

Whatever you get, you probably want ef-s or 3rd party instead of Canon RF glass. It's *way* more optimal to get an aps-c lens if you're going ultrawide, especially if weight matters, as that extra image circle takes a ton of extra glass.
Well I don't think there's much of a 3rd party selection of lenses for underwater, but looking around now, I'd be really happy to try R50V+Sigma 10-18/2.8.
Problem is, neither Nauticam nor Ikelite have case for R50V.

It's been 10y+ and I'm still waiting for a great compact underwater setup.
I'll just keep on dreaming about an RF-S fisheye zoom or an R8V+the rumored RF fisheye zoom....and case...almost none of the components of my dream exist today ;)
(and then we didn't even go macro where the reality is worse)

Honestly, you should look outside of Canon, heh.

A Lumix S9, for instance, has underwater kits. It's light, cheap, full frame, with tons of bright 3rd party ultrawides. Sony's Z series may have some kits too, and actually supports stuff like gyroflow stabilization in post.


The only reason I got an R50V instead is for Canon's better budget telephotos and some legacy lenses. And even then, the cripple hammer is making me look around quite a bit...

Uh no way. Canon I can use as a second/backup body, or just carry around for street photo, family photo, whatever, with huge lens selection I already own.
Btw the Lumix S9 is not the best idea, as again, no Nauticam or Ikelite housing is available.
The only brand I'd ever consider other than Canon is Sony anyway.

Exactly my point.
6mm lens, no thanks.
15/2.8 crappy lens.
Using an adaptor in an underwater system which I'm trying to make smaller, no thanks.
There's no real good solution.

Maaaybe with this RF fisheye zoom and an R50 V.

I had a 40D with the Tokina 10-17, it's waaaay to big. Btw I'm also trying to avoid Ikelite next time.
You want full frame and want small but fisheye needs a big dome
Didn't you say that you wanted full frame but now R50V? The new fisheye is for full frame so you won't get a circular shot with crop sensor.

Using the FCON-T02 wet lens on the TG7 will be the smallest option for what you want but it seems that you want quality as well!
TG7 is also quite good for macro given its size. Being that small allows you get much closer than my bigger rig.

Why not Ikelite? Ikelite don't have a current housing for it but I have sent them an email to confirm.

Nauticam look to only support the R50 with one lens RF-S 18-45mm F4.5-6.3 IS STM with a flat port (not dome as I guess it isn't wide-enough angle).

Sea Frogs seem to have a compatible housing for the R50 and support 6-7" domes but don't mention any fisheye support. I haven't heard of this manufacturer before.

My wife would love for me to have a smaller rig for travel but there is nothing that handles the R5 and macro/wide angle that is much smaller/lighter.
