Egami (translated) spotted a new Canon lens patent describing a 50mm f/2.0 lens. Egami “speculates” that this may be a lens for a Full Frame mirrorless system. Yep, as far as I understand there is no evidence this lens may be designed for a mirrorless system. May Japanese readers can help me to understand why Egami is making such speculation. That said I believe it’s inevitable that sooner or later Canon, Nikon, Fuji and Sony will launch a FF mirrorless system.
By the way, Canon already launched a similar lens for the FD system! It is the [shoplink ’55mm 1.2′ ebay]55mm f/1.2 (here on eBay)[/shoplink].

As I read in canonrumors.com the 50mm lens that is possible for a mirrorless full-frame would be a 50mm 1:2.0. Besides this lens there is also a 50mm 1:1.2 L replacement for the one already on the market for SLR-Mount EF. All rumors.
And there was also a 50mm 1:1.2 for FD Mount.
proper FF mirrorless = SONY(definitely”with lame lens lineup”), fuji(might be), oly-pan(less likely),canikon ………………….(mehhh).
If you compare the distance between the first and the last element ore the elements at all to the distance to IP i think, there is enought space for a mirrorsystem. Why should this be, if it is a mirrorless lens?
Does anybody has a 5D and a 1,2/50mm to check it?
if you are familiar with optical calculation, You would realize that this strong symmetrical construction never could have a speed of 1,2 .. looks more like a 2.0/50 mm , evtlly optimized for near field/macro shootings..
Yeah, there’s a huge gap between the rear element and the imaging plane, not like on the Voigtlander 50/1.1 for e.g., so I think this is for a SLR.
Just for fun I used the specs from this patent to build my own version of this lens. then I built a mirrorless camera to go with it based on the sensor in the 1DX (with some tweaks).
I’ve been out shooting with it this morning. Unfortunately it suffers from massive amounts of purple fringing and the contrast AF is so slow that I smashed it to pieces in a rage….
the f1.2/50 patent is not for the new Canon FF mirrorless but but for current EOS line.
the f2/50 design also patented this time is actually for the new mirrorless FF from Canon.
Brilliant example of how the rumor network operates! Notice how lens patent spotted in the text becomes lens spotted in the headline.
I would wager people are just too quick off the text … lol … just read the whole article egami posted. There is in fact several illustration which depict the f/1.2 lens as well as the f/2.0 lens optical design together with some comparison from Zeiss and Leica. As they say its the fine print that tells. The 2.0 lens is quite clearly a image height of 21.64mm and Back Focal distance of 28.86mm – that means the image circle is something like 43mm+ ( aka 35mm film FF ) and that Back Focal distance is certainly not any SLR type , in fact it correspond to Leica Screw Mount quite well.
Now picture this, before the EOS, in fact before event the FD, Canon made loads of Rangefinder in Leica screw mount. So really should it surprise if Canon aim to revive their beginning in a digital form ( a mirrorless FF , well likely no more rangefinder , but that’s fine with me
A Canon Mirrorless styled after their old Leica Screw Mount RF body would be pretty retro and chic I would guess, and well an updated mirrorless mount ( I would not mind a electronic coupled version of the Leica M this time ) certainly would be there if it come to be
