Canon EOS R6 Mark III & RF 45 F1.2 STM November 6

Correction (I read the communication incorrectly). Optical quality on par with the EF 50 f/1.2L USM.
Wow!
So maybe I could buy this cheap 45mm and buy the 85mm 1.4 VCM using the money I thought I would use for the RF 50mm 1.2...

But I need to check the optical quality first: I never liked the cheap RF 50mm STM and I'm currently happy with an adapted Sigma 50mm 1.4 Art.

why to spent money on a RF 45mm 1.2 STM lens with similar optical performance but weaker built quality
Ditching the adapter, IMHO of course, is worth enough for spending the money; also, I don't know the used price of the EF 1.2 L but I guess is on pair or more expensive then the new RF 45 1.2 so there's also some possible saving. If the thing is good enough, I'll gladly ditch my 40 Art and hopefully get 50/100€ extra in return (but same price swap would be ok, too), without the hassle of the adapter.

Then, build quality in 2025 is good enough even on cheapo chinese lenses, let alone a first party f1.2 lens, which is also going to be serviced for the next decade or two, while if the EF L is not going to be serviced for that long (if even still serviced today), and could end up becoming a fancy paperweight.

That's why I immediately swapped the EF 24-70 L II with the RF 28-70 STM as soon as I saw that quality was same or better; new lens, two years guarantee, no service problems for at least a decade, no adapter, shorter, lighter, stabilised. The new RF 45 would likely be the same, if quality is what we all hope and expect.

Canon’s RF/EF Lens Production Exceeds 170 Million Units

Kind of between 2009 and 2014 they produced 50 millions lenses (10 millions average) and between 2014 and now 70 millions (6,36 millions average). So they are definitely slowing down, we don't have more precise data's in the article. RF could have had a noticeable impact on this average per year.
2009-2012 was the peak of digital camera sales when everyone was buying DSLR's.

A lens with that character for sub $600 is still awesome. That's about the same what I paid for the EF used. Not everybody's hunting for a tack sharp lens that is stripped of all optical imperfections.

Even if it's the same optically, the AF might be much more reliable.
On Canon RF bodies the AF reliability of the EF 50mm 1.2 L (and all Canon EF lenses) is much much better than it was on Canon DSLR bodies. Even the RF 50mm 1.2 L lens is hardly any better at autofocus. So why to spent money on a RF 45mm 1.2 STM lens with similar optical performance but weaker built quality. Ok, some less weight.
I would replace my EF 50mm 1.2 L with a RF 50mm 1.4 L VCM, in the future.

@padam I've always read the original R6 had a 19ms readout for photo, and the Mark II had 14ms.
Anyway, the C50 seems to be in the same ballpark.


That's assuming you're doing any of that in-camera, which most don't. Plus, only Canon DPP can open the grouped photographs, on the computer.
Yes, I'm doing it in-camera- because that is SO MUCH EASIER.

USB C Cable for R5II

I don't know if it fits your budget, but Cobra Tether cables are excellent and should work with Camera Connect.
Thanks,

They do look good. Unfortunately I’ve since discovered that remote shooting on the R5II using Camera Connect only works via Bluetooth or Wifi.

I had been hoping to use the USB-C cable to eliminate the lag you get using Camera Connect for remote shooting.

Might need to look to see what other apps allow for remote shooting of the R5II via USB-C.

Oh, so my initial suspicions were right. That makes a lot of sense, considering the double gauss design we saw on that patent.

If the double gauss design is confirmed, this could be a successor to the EF50mm f/1.2 L, this time aimed at enthusiasts. A very interesting proposition.
This may be a lens with a lot of character.
