Have Canon ever made such a lens? I don’t think coma has ever been any kind of priority for any Canon lens that I can think of.We do not yet have a RF prime for astrophotography and nightscapes. I hope that 24 f1.4 has sharp, low coma, corners.

I have to agree which is a little strange as Canon have their dedicated astro bodies.Have Canon ever made such a lens? I don’t think coma has ever been any kind of priority for any Canon lens that I can think of.
I think the 'A's have always been aimed at telescope users rather than very wide field shooters. Of course you can get excellent results with the big whites, but that is different again...I have to agree which is a little strange as Canon have their dedicated astro bodies.
Your next models will be quite different in Arkansas.Of course, these are just patents. I do wonder though, why not f/1.2 for the 24mm? I know, I know... not a big difference at all. Still, I wonder. I'm guessing a 24mm f/1.4L would dash any hopes of a 24mm f/1.2L. Would f/1.2 on a 24mm just be too huge?
I hope the RF 50mm f/1.4 is a great lens. My Tamron 45mm is pretty darn good for the money, but focus seems slow to me.
Moving to the Ozarks in Arkansas in a couple weeks (tiny town of about 3,000 residents), so I may have to switch to wildlife and landscape for my hobby. Can't wait to start fly fishing again. It's been years and years.
The patent says it will have 100mm in length. And the number of lenses at drawings suggests it isn't going to be lightweight either...As someone who learned photography with the EF 50 1.4 as my main lens, I can't wait for an RF version. I have the RF 50 f1.2, but its girth is enough to make me leave it at home sometimes. The 1.4 would never leave my bag.
I think he felt 'outed' but I could be wrong. He did put a lot of attention on himself with the 50 for a time however.I have not seen him here in quite awhile. Hope he and Don are ok.

The EF14mm f/2.8L II has coma but it's not at the disgusting level of EF24mm 1.4L II. It has been my favorite for Astro for years.Have Canon ever made such a lens? I don’t think coma has ever been any kind of priority for any Canon lens that I can think of.
The patent is not about a mount. It's "to suppress aberration variation during focusing".One thing I don't understand. The RF 50mm 1.4 usm is listed twice as long physical, as the old EF 50mm? Why did Canon make a new lens mount that requires so big lenses?

Why did Canon make a new lens mount that requires so big lenses? I don't get it... I would love to go back to Canon, but with these new big lenses - I will consider the Fuji GFX system instead.
Thanks, but that is too theoretical for me. I'm just a photographer. The old EF lenses were great, lighter and smaller. Still would love to have a mirrorless Canon with EF mount. But hey, I mainly do street and documentary photography. So I guess the R system is not necessary. Retrofocus lens design or notgoogle double gauss vs retrofocus lens design
It's a simple comparison. Smaller and lighter with lesser sharpness and aberration control or heavier and larger with better sharpness across the field plus better distortion control. however some retrofocus clenses an give a certain look a lot of shooters do not appreciate i.e. sigma 'sticker look'.Thanks, but that is too theoretical for me.

Yes, but Leica M lenses are not that big. They are known for sharpness and aberration control. And I wouldn't say that their small lenses are not sharp across the field. And distortion? I know they have the rear element much closer to the sensor. But the RF is not that far away, as I remember.It's a simple comparison.

Knowing a bit about lens design can make you a better photographer since it will assist in your future purchase decisions. This isn't akin to understanding sensor physics like some here salivate over. I too am a'just a photographer'.
I'm okay with it being bigger than the EF version. My point of reference is the RF 50 f1.2. It's just a little too big to lug around. At night, I will grab it because it is something magical in low light, but the extra stops isn't necessary during the day. The other point of reference is the RF 2.8 24-70 which feels less girthy and less front heavy than the RF 50 f1.2, which just happens to be what I'm comfortable with balancing on the R or R5. This RF 50 1.4 is assuredly smaller and lighter than that lens, which is enough for me.The patent says it will have 100mm in length. And the number of lenses at drawings suggests it isn't going to be lightweight either...
