Patent: EF 85mm f/1.2L III and Others
« on: March 31, 2014, 07:51:35 AM »

A patent showing new 85mm & 50mm designs has surfaced. Both an 85mm f/1.2 and an 85mm f/1.8 appear as well as a 50mm f/1.4 and a 100mm f/2.


An updated 85mm f/1.2L II has been mentioned as being under development for quite some time, and we’re all expecting a new 50mm lens, which is an oft rumored product.

I would be particularly interested to see what an updated EF 85mm f/1.2L would be like. The II is an awesome piece of glass yet a little clumsy and slow. Optically I love it!!!

Agreed, sharp as a razor wide open, just slow to focus.

Stick the AF speed of the 1.8 in the 1.2 BOOM!

The 85IIL is bitingly sharp wide open, although the AF is slow it's still very accurate. But I'm not sure I'd be selling my mkII for a mkIII. There's not much to update here, especially if my existing copy is so good. My copy is sharper than my 135L wide open. It's THAT good!

A new 50mm f1.2 II L, well there's not much more to say to that than "bring it on" and lets hope it's better than the last one. The Zeiss Otus and new Siggi are the new benchmarks, where as most of the 50mm lenses from Canon have been sub optimal in the last 20 years. It's been a game of which drawbacks is a photographer prepared to put up with as opposed to which features are most useful.

The other two lenses? Well, not really my bag.

Looks like 50mm 1.4 ... hope they add IS ... for video

At 89mm, the new 50/1.4 design is 16mm longer than the existing 50/1.4 design and 11mm shorter than the Sigma 50/1.4 Art lens. The Zeis Otus is 127mm long.

Whilst the Sigma and Zeis will have gained IQ with length, it seems reasonable to assume that the Canon 50/1.4 will grow length to accommodate IS rather than IQ.

I could go for the 50 1.4 and the 85 1.8 if they have IS.   The big issue is that they are probably 2 to 3 years out for me....

... first they have to get announced (months or years from now), many  months later they may be available at a very high premium, and then 12 to 18 months until the price becomes reasonable.

I love, love, love my 85II for all reasons stated above, but seriously, this lens has really bad LOCA that's difficult to fix in post.

If they found a way to reduce the green/magenta bokeh CA, I would upgrade in a heartbeat (assuming that's even possible on 1.2 lenses)

I'm waiting for the mythical Canon 50mm F1.4 IS. If it takes too long, I go for the Sigma.

Yeah, I know what you mean. I have been eyeing the current 85mm 1.8 for a while, but every time I consider ordering one I hesitate knowing in the back of my mind that an updated version with IS is coming. These patents keep popping up, but seriously how long does it take? The 50mm 1.4 replacement in particular has been rumored for a few years now.

I would love a new 85mm with IS, but $500 is about the most I can pay for it. The 24 28 and 35 IS all started pretty high but dropped to around $500, so that's what I'm hoping the new 50 85 and 100 IS will cost (if not from the start, then a few months to a year later).

I know the current 85mm 1.8 is still a nice lens, but I'd really rather not deal with buying and reselling, and if I wait for the new one to at least be announced and I can't afford it, the current 1.8 might go down in price since it will be the "old" model and more people will be selling to upgrade.

I would love to have the 85mm IS as long as the price is right.

If there's one prime 'bokeh beast' I'd love to have in my bag, it would be the 85mm f/1.2 mkiii!!!

A fellow club member who photographs for magazines has one and I think it's an incredible lens, aside from the lethargic AF.

Would I want a 50mm? I'm not sure anymore. It used to be a future endeavor for me but my 24-70 is pretty awesome at 50mm...

But yeah, I think it's time we see some of these rumours manifest in plastic, metal and glass!!!

It is correctable to some degree through use of APO lens designs.  As always, though, there are varying degrees of effectivity even among respective APO designs, and if we REALLY demand the goods...we're probably in Leica territory for price. 

The third party makers (Sigma!) often designate APO on lenses, but while the design may be APO, their particular realization of the design usually leaves much to be desired.  This can be due to any number of design constraints. 

Canon's L-series Flourite coatings are part of their APO equations where used.  However, to the best of my knowledge, the 85mm f/1.2L is not an APO design.  Maybe someone has more or better information than I have, though.

Leica made a 90mm APO lens that will show you what REAL APO can achieve in shorter lenses in the portrait range.  It sold for almost $4k, though.  How badly do you want rid of that LOCA on the Canon 85?  I'm pretty ok with mine! ;-)

It's just a patent. So, I will continue enjoying my EF85mm 1.2L II for the years to come  ;D
