Canon RF 50mm f/1.8 pancake?

https://www.canonwatch.com/upcoming-canon-rf-50mm-f-1-8-stm-lens-shows-up-at-certification-authority/

This is the lens I'm still waiting for. Based on the patent, it looks to be about 1.2" (vs the 40mm pancake that's 0.9"). I wonder if they're delaying it due to the loss in sales of the 50 1.2 that'll most definitely happen to some degree. I mean, I'd consider getting the 50 1.2 right now if there was no 1.8 pancake rumor.

The pancake for the EF system was 40mm, and the RF system flange distance dictates it must be wider focal length to keep the same pancake size. Any new RF 50 won't be a pancake like the EF 40 (but it will certainly be smaller than the RF 50 f/1.2).

You might be the only person where it's a coin toss as to whether they want a $2300 uber f1.2 prime or a cheap f1.8.

I don't see anything about a pancake. In theory, with the flange distance, it could be a little longer than 30mm in length, which is very small. But I'd expect it to be more like the RF 35mm in size or Sony's FE 50mm 1.8 in size.

(Actually just checked the link to the Patents and it describes a few configurations at around 60mm in length, so basically what I surmised above)

If you want a cheap 50mm today, the 50mm STM on the EF adapter is very light and compact and it's easy to find at $100.

I took a RF 50 1.2 patent and subtracted the length difference from the actual length to get the subtraction value. What is the actual subtraction from 58.55mm to get the length of the lens? Btw, I already have the nifty fifty. Works great at f2.8, but it's too noisy for family video work.

Re: Canon RF 50mm f/1.8 pancake?

I don't see a pancake lens at 50 - probably a little longer than the 50/1.8 STM, but still shorter than that lens with the adapter.

I do wonder if they'll do a 50/1.4 at some point.

I also wonder if they'll do a pancake lens at whatever focal length its practical (35 mm, maybe).

I'm fine with a 50 the size of the new 35/1.8.

My only requirement is that it has to be sharp as h#ll.

It's been a long time since I was in college, but I think the math equation you are looking for is 58.55=58.55

Would surely round out the kit nicely.

Although if I have 24 and 50, then I want a 135mm.   85mm is too close to 50.   So lets also ask for a compact 135mm f2.8 like the olden days.

24/50/135mm is a complete, travel the world setup.

Oh. You really don't know. You think it's the actual lens length.

I'm hoping the f/1.8 will be expensive and value for money.  I don't see why you should be forced to lug around heavy lenses if you want high quality.

I don't see anything about a pancake. In theory, with the flange distance, it could be a little longer than 30mm in length, which is very small. But I'd expect it to be more like the RF 35mm in size or Sony's FE 50mm 1.8 in size.

Sharp as h#ll, and no extreme vignetting please. Oh, and perfect round bokeh circles across the frame at f/2.0 or f/2.2 please without pronounced outer lining. I bit like the Samyang 85mm f/1.2 XP would be nice.   Oh, and no fringing of course.  3 stops of IS is enough. Canon can skip the other 5 if that will make a smaller design possible.   And i don't need a macro feature at 50mm too, so if skipping that too to make it more compact it's fine by me.

I think it should actually be a little bit bigger than the 35mm. Not too big of course, but it should be big enough to meet the other requirements, you know.....

+2 And for me it wouldn’t even need macro capabilities since it would be my low light group photo lens.

A sweet trio for travel indeed.  Myself, I’ve got travel covered by a nice compact M system.

And since I’m not going to be picking up the big boy 85 f/1.2, I’m adding the RF 85 f/2 for portraits, and probably would skip a 135 (unless I just get the excellent existing EF 135 f/2).  I have the little 35 already, so it’d be nice to fill out the quartet with 24, 35, 50, and 85 mid-level primes.  Which is where Canon needs to go to prep the way for their (anticipated) lower tiers of RF bodies (to replace the Rebels, xxD, RP and original R).

+1 Keep vignetting to a minimum since I’ll be using this as a general purpose lens and not just for portraits, plus this’ll help to keep the bokeh balls round!  

But reducing the fringing (c/a) with the inevitable aspherics is surely going to give us some onion ring bokeh, esp at this level of lens.

IS would be nice, but I’d get by with IBIS (R5).  However IS will be welcome for use on the lower tier bodies (at least for the time being).

Lastly, 1:2 macro would be very handy at this F/L (for me).

Oh boy, i want best of both worlds.    But if i have to choose: no onion rings please.

IS would be nice, but I’d get by with IBIS (R5). However IS will be welcome for use on the lower tier bodies (at least for the time being).

You have to wait for your R5, but i will have to wait about 2 years more to save up for it, so having a bit of IS in the mean time won't hurt.  I also think the quality of ILIS+IBIS might still be better than IBIS alone, while at 45Mp the bar is set high for your IS system.

Lastly, 1:2 macro would be very handy at this F/L (for me).

O.k.  Well, i wouldn't mind if it's there. But isn't it a bit redundant to have this in the 50mm if you have it already in both the 35mm and 85mm?  The 35mm to include a lot of background, the 85mm to exclude a lot of background?

Well for serious (targeted) macro I slap on the 100L and my lighting outfits. But with these other lenses the 1:2 will just be for (close-up) photos of opportunity. By including this capability I think Canon wants to make these lenses as appealing to enthusiasts as possible.

At 50mm somewhere around 0.20 to 0.25ish would be enough for me. But Canon will put 0.50 in that 50mm, that's for sure.

The magnification factor of the 105mm Art is a pain. 0.12 is not enough.

Re: Canon RF 50mm f/1.8 pancake?

Have had my R5 for a couple of days now and will mainly use it for my EF 500/4 IS II. Will keep my Sony A7III for use with adapted Leica-lenses and Zeiss 55/1.8 Sony FE 35/1.8 and the new Tamron 17-28/2.8 (a really great lens).

Will it ever be possible to buy compact, light, high IQ-lenses as above to the R5??

(and no IS please, will make it bigger-havier-expensier. The new R cameras = IBIS)
