Canon RF 24mm f/1.2L & RF 85mm f/1.2L in the works [CR1]

What are you talking about? I didn't say you weren't allowed to have an opinion. Don't be disingenuous. I said that if you're going to make groundless, sweeping generalizations with no support you should be called out on them and asked to provide backup, support, and evidence. Otherwise what's the purpose of your post? Anyone can throw out an opinion, but if this forum is going to be anything other than a bunch of farts lost in a breeze, people need to provide support and evidence. The threads here are a joke-- baseless assertions, wild opinions presented as fact, just a bunch of bloviating. I'm asking you to support your statements with evidence, logic, and reason, which you have been entirely unable and unwilling to do.



This is not a dSLR. It's a mirrorless. And since you don't appear to be an engineer, why exactly should we take your claims about this "only affecting wide angle lenses" seriously?

Here's a question I doubt you'll be able to answer: If your claim is accurate that the new mount doesn't have any real advantages at 50mm, why is the RF 50mm so sharp in the corners, whereas other ultrafast 50s struggle there? Don't you think if Canon could update the optical formula of the EF 50 1.2 to improve corner performance they would have? The point is, the RF mount appears to allow engineers to make fewer compromises. The Sigma 50 1.4 Art is noticeably less sharp than the RF 50. Considering the only 50-ish lens that competes performance-wise with the RF 50 1.2 is the Zeiss 55mm 1.4 Otus (see side-by-side here), I don't think your claim really stands up.




On what do you base this claim?
So you come here...like a newbie....throwing your weight around and yet you contribute nothing in the way of your photographs or portfolio. I am not answerable to you and my opinions are forged from my real world professional experience. I've been here a long time and my voice carries weight because I have been known here. The only joke here is you. You are the one pointing the finger, taking offence where none was intended and the only bloating seems to come from your own over worded and rather personally directed posts. If you feel that this forum isn't worthy of you...it' probably isn't and I for one won't miss your attitude or your unspectacular 44 post. Got any good recent photos that might sway my opinion of you?

:cry: BTW, where's neuro? Oh me oh my, what we have to tolerate, but it's nothing compared to when the 6D came out. If I'd been on CR then I might not have bought that most capable little camera - they came out of the woodwork faulting it because it HAD WiFi. Believe me it's true.:giggle:

Then there are the authorities that would have you believe that if you place an EF 2X III on a 300 2.8 II all your photos will be ... well, very poor. In fact, you should never place one of those gizmos on any respectable lens. OK. Glad I didn't know that.;)

I came to CR as a complete ignoramus posting incorrectly and asking "dumb" questions and I never once was attacked ... because ... I'm a sincere half decent person who tries to contribute in spite of not knowing much and try hard to stay away from personal attacks. And I've learned a lot being here.

Hmm, I think also of how we've had to endure DR, that dynamic without which it is not possible to take a decent photo if it's below 14. Everyone should know that, right. :)

Never the less, I'm glad CR isn't constantly being censored over opinions and I can always split from a thread when I've had enough. Long live CR!

The Sigma lens (on 5DIII and mk4 bodies) to be lot sharper optically. But a lot more inconsistent with it's AF accuracy. A very hit and miss lens. I don't have much faith in Sigma as a brand and my experiences with Sigma are well documented here in these forums.
They might gain a new lease of life on the EOS R though, because I found the focusing to be consistently good in live-view (on a 6D Mark II), I just don't like using the rear screen at all times.
Looking at images, I do prefer the look of the RF 50/1.2 over the Sigma EF 50/1.4, I'm just not sure it worth 4 times the price. I wonder if they are going to bother with converting the mount to RF (or Z-mount) like with E-mount but with three different EF-RF adapters, there is probably no need for it.

And where's ahsanford? They have both been conspicuous by their absence - I think ever since about the time the EOS R was announced?

Don't know about ahsanford, but neuro has been posting on some threads, such as the one on M cameras.

But I do get fed up with some of the idiots on here who pop up out of nowhere...post a few posts and then question every one they don't like and think that we are all required to justify everything we say or do...while offering no images or contribution in return.
Could't agree more. I believe I am a reasonable contributor as well and whilst I don't post images to the lens threads I have posted hundreds of illustrative images in regular threads to illustrate or demonstrate something.

As opposed to your bloviating, groundless, sweeping generalizations to which you offer dishonest support and call the poster who does supply illustrative images "stupid" and "idiotic"?

I supported my 'opinion' (which is basic photography 201) with actual images that destroyed your 'evidence', you replied with curtness and insults, just who is setting the tone here?

If they release a 70-130 f/2 so many portrait photographers will either buy it or sales vate over it (if they're not Canon shooters, or don't have the budget). That will be an amazing lens.
They will either complain about the size, weight, and cost just like the 28-70 F2 even though they secretly lust over it. People always find something to complain about it nowadays.
