Canon Says it’s up to Sigma to Make Full-Frame RF Lenses

Personally, I helped develop a breakthrough cancer therapy that has benefited millions of patients so far.
I'd be curious how you define "helped". By being the janitor? It's a critical job to society in general but I think it might be a bit of a stretch to equate it to helping with a cancer treatment.

I wonder what @mimbu has done to benefit society? Evidently he doesn't realize that by being an insulting buffoon on an Internet forum, he benefits no one...least of all himself.
I volunteer at animal shelters and donate as much as I can. Honestly dealing with people like you makes me much more inclined to help mistreated animals than much of the human population.

Canon Shows off Interesting RF 55mm & RF 85mm F1.8 Designs

Finally these just might be stuff I have been praying for, especially the 55/1.8.
The 50/1.8 is is cheap crap, and although I bought the 45/1.2 which is much better quality, it's size and weight is more than what would be ideal in scenarios when it matters.
I'd be happy with a 55/1.8 around 250g.

Also, a 85/1.8 with better AF but not more weight would be a welcomed upgrade to the 85/2.
I'd pre-order both.

Many of us have figured out that you’re asinine and irrelevant.
Yet, you cannot resist replying. You're like some sort of bot. Push buttons, get reply. It's very entertaining, I must say.

Repeating myself, but you perceive statements of fact as 'defending Canon'
Your delusions of grandeur have become so strong that you think your opinions are somehow fact. Interesting.

I've agreed that Canon is blocking 3rd parties from making FF AF lenses for RF.
That's about all there is to say on the matter then.

Report: New Canon Super Telephoto Lenses Coming in May

omg, how heavy was this lens? According to google AI, it was 16,8 kg. Instead of a tripod one should have probably used a golf cart :ROFLMAO: Useful for a safari, for sure. But for which sport would one use a lens like this?

Those five FDn lenses were all converted to EF mount (with the TC removed).

You might feel differently if you owned one or more of these...

That's higher end, I think he meant the old gold rings, and the best modern silver rings, like the EF 35mm f/2 IS USM, and EF 24 and 28mm f/2.8 IS USM.
IIRC, only the EF 50mm f/1.4 USM was on the lower side of things, with external focusing.

In my experience, for now, the only lens that is comparable is the RF 45mm. The RF 85mm f/2 could be another one, if it didn't focus externally.

I somewhat agree, these RF STM primes are the only lenses I've consistently been wishing to replace.
I ditched the RF 24 1.8, 35 1.8, the next possibly will be the 50 1.8 (I'm considering keeping it for the size, but it's unlikely), and the two other lenses I always look forward to replace are the RF 28 and RF 16, even though I consider these two to be a little more pleasant to use.

I don't need red rings on all my gear, but I would have paid an 100 or 200 extra bucks for the same lenses with a more refined experience.
Internal (front or rear, whatever, I don't care), quiet and smooth autofocus, dedicated lens hoods threads, and dedicated clicked control rings for consistency.

I don't think that's a lot to ask.

Not two TC, but Nikkor Z 600mm f/4 TC VR S is something Canon should have made long ago.
Yes, and it only took Nikon 9 years to innovate that switchable 1.4x TC, after Canon launched the EF 200-400mm with that feature in 2013. Or if you prefer, you can start counting from 1984 when Canon released a handful of FDn 1200mm f/5.6L + 1.4x lenses for the LA Olympics.

Essentially nearly none of the RF lenses in the "normal" focal length range make me proud to own, hold, touch, and operate them. they all seem like cheap lenses on their outsides with optics that are sharp yet make lots of distortion, with many of them with cheap feeling and looking extending barrels (and yes i get the physics/optical compromises/packaging considerations etc)

Loved the big front elements of yesteryear too.
Oh, they're still around.

Front Elements.jpg

And even though the front element of my RF 85/1.2L DS is a bit smaller than that of my RF 28-70/2, the RF prime's front element is larger than that of the EF 85/1.2L II that I owned years ago.

A 600mm with a built in 1.4 and 2.0 would be a "hold my beer" moment and probably break the internet :) Is there any lens around with such a design feature? I couldn't find one with my quick google search.

I dream of owning a big white some day. Which one depends on which sport my kid(s?!) will be doing.

Hopeful. I always thought the RF 50 STM and 85 F2 IS were awkward and out of place -- not in line with other manufacturers offerings that are quiet, silent, and modern/non extending. The RF 50 was just lazy and i always hated that it was merely a reshuffled EF 50 STM which itself was just a re-dressed design going back decades. I'm sure the 50 STM will still sell along side any more higher priced sibling, but there should be a quiet internally focusing higher quality lens in the 50 1.8 arena than what is currently being offered. In terms of the 85 macro.. really i could do without the macro feature. the decades old EF 85 1.8 seems way more polished in operation and materials.

Give me back the look, feel, and operation of the old EF lenses that look and feel good to the touch, focus internally quickly and quietly. Loved the big front elements of yesteryear too.

Spring 2026

Well, it's April and technically it's spring now. I thought we were done with snow in Boston, as did the tiger lilies that are pushing up through the mulch in my front yard. Only ~1 cm, and it will be gone by afternoon. I moved here after the April Fool's Day blizzard in 1997, but people still talk about that here.

"Spring?"

You have reached a new low. Cancer kills millions of people each year.
Personally, I helped develop a breakthrough cancer therapy that has benefited millions of patients so far. I wonder what @mimbu has done to benefit society? Evidently he doesn't realize that by being an insulting buffoon on an Internet forum, he benefits no one...least of all himself.

Yeah, I thought about changing that, but figured that even you would manage to figure it out. I guess maybe not?
Obviously, you thought about changing it after I pointed out how asinine and irrelevant your statements were.

Many of us have figured out that you’re asinine and irrelevant.

Or you just prefer to be a dick?
Name calling, really? You’ve already clearly demonstrated that you’re puerile. Maybe you need to look the word up. It seems you feel compelled to keep confirming that. The (situationally modified) adage you should take to heart is, better keep silent and be thought a fool than put fingers to keyboard and remove all doubt.

Meanwhile, Canon will continue to indefinitely block the sale of 3rd party FF AF glass, to the detriment of their customers.
So detrimental that customers keep buying Canon cameras in numbers that enable them to continue strongly leading the market.

You are free to continue not buying their gear in protest, and you are free to continue complaining about it on the Internet. You are also free to piss into the wind, which has about the same level of effectiveness.

And I will continue to be amused by the likes of you trying to defend Canon's behavior.

I recommend you stop with the corporate bootlicking before the boot polish gives you cancer.
Repeating myself, but you perceive statements of fact as 'defending Canon' because you're on the offense against them, as ineffectual as that is. I've agreed that Canon is blocking 3rd parties from making FF AF lenses for RF. They make the cameras, they own the IP, they get to choose. It's business. I understand that, but to you it's personal. Attack and defense. It’s sad for you that reality interferes with your pathetic little world view, the one where your opinion matters at all.
