Which website I can find the MTF charts for this lens and older Canon lenses?
canon.jp's website - i've used it so much i don't even have to translate, and i don't even know japanese.

Correct - if you shoot mostly stills or nearly fixed people. If you want to use such lenses in the street or join a party, you need servo AF to get reliably in-focus shots with such lenses wide open. Given the lots of light such glass can suck in, even with my old 5D3 that was officially only sensitive to -2 EV in the center AF field (if I remember correctly), I could use AF in surprsingly dark settings. Of course, there were limits, but last but not least photography is based on light, not on the total absence of lightIf you’re shooting in extremely low light, One Shot AF is the way to go, as Servo AF isn’t as sensitive.
I'm interested in knowing if that still true for R5 MK2 like camera. Because all the videos I saw about configuring the camera said to use Servo AF.That’s not his point. All camera bodies can only achieve the maximum sensitivity for autofocus when using One Shot AF.
Many cameras in the past were rated at EV-3 using f/2.8 — that was achieved using only the central AF point in One Shot AF.
Current cameras are rated at EV-6,5 using f/1.2 — that is achieved using single point AF and One Shot AF as well, but now you can move the point around.
If you’re shooting in extremely low light, One Shot AF is the way to go, as Servo AF isn’t as sensitive.
It really depends on the setting. Disco lights, for instance, can make servo AF very unreliable, because the colors are always changing. Plus, it's not that hard finding venues dark enough that servo AF doesn't work, specially off-centre, where lenses have the most significant vignettes wide open.If you want to use such lenses in the street or join a party, you need servo AF to get reliably in-focus shots with such lenses wide open.
I don't mean to sound rude, but I'm confused: you disposed of your time watching videos on how to setup the camera, but didn't bother reading its specifications on the manufacturer's website?I'm interested in knowing if that still true for R5 MK2 like camera.

Not yet, only got it a week ago and didn't had time to read the full manual.It really depends on the setting.

Yes, the asterisks are still there, they'll probably always be.
Heh Heh ICWYDT.Not yet, only got it a week ago and didn't had time to read the full manual.
The aperture dependent focus shift of EF50L is from the undercorrected SA which also gave the lens its character in oof rendition. Which is less of a problem on mirrorless as focusing can work stepped down. But this new 45mm, from what I can see in the sample images actually feels more like overcorrected SA thus having a more vintage look than the EF 50L dreamy look for the bokeh. Which is also part of the reason why I'm disappointed that it is not the patent previously released.I had several copies of the EF 50mm f1.2 L and I found it to be a frustrating lens to use. It was built like a tank and handled lfare really well. It had great colours and a lot of charector. BUT in low light (exactly when you want to use a f1.2 lens) it's AF was ponderous, hessitant and often would not lock on. I'm talking single point One shot mode. I would have to use one of the the verticle centre points on my 5DIII to have any hope. And yet my EF 24-70 L would nail AF effortlessly at 50mm and that was a lens far less bright in terms of light transmission. Which goes to show that wide open contrast was more importaint to the AF system than brightness or light level.
The other issue with the EF 50mm f1.2 L was the well documented aperture dependent focus shift. At close focus distances, if you stopped down to f2.8 (where this lens actually became quite sharp) the point of focus was fine in the view finder, but in the final shot, it would jump significantly.
I've not tried the EF 50mm f1.2 L on a modern mirroless camera body. but under the older DSLR AF system...it was too erratic and unreliable for my professional needs at the time.
First of all the weather sealing would be worse (In this case can be fixed by adding a UV filter as the filter thread seem to be on the fixed barrel).What is wrong with all groups moving? Sure its more mass so the autofocus *could* be faster if it was true internally focused, but in my reading its generally easier to maintain sharpness and corrections when you move all the groups.
I like what Nikon are doing with their midrange primes.I'm ok with the softness but certainly not expected this much CA. Looks like a 50 year old manual focus lens. The Nikon Z 50mm f1.8 S is exactly the same price in UK and there is no question which one is the better lens.
*lol* What a w** dream. Especially with the "L" in it.The new 45mm lens should have been RF 50mm 1.8L USM. Instant buy for under $1k.
I dont shoot video so I dont really like the VCM line and how they prioritize pointless video features over photography. Terrible value for 1599€ or over 2k for the 85mm.*lol* What a w** dream. Especially with the "L" in it.
But I can help: just add about $500 and in return you'll recieve f/1.4:
Go and buy an RF 50mm f/1.4 L VCM
Actually, the 50 VCM is the best optically corrected VCM lens of them all. It vignettes and distorts less than the RF 50mm f/1.2. It's a terrific lens.I dont shoot video so I dont really like the VCM line and how they prioritize pointless video features over photography. Terrible value for 1599€ or over 2k for the 85mm.
What pointless video features would that entail? All I see is a good photo lens that can also be used in video.I dont shoot video so I dont really like the VCM line and how they prioritize pointless video features over photography. Terrible value for 1599€ or over 2k for the 85mm.
For a start, an aperture ring which is usable for photography only if you have the two latest (until 3 days ago) and more expensive bodies, while all the other bodies make no use of it. But I admit I didn't really went deep on VCM's features as their price is unreachable for me, so I didn't even bother reading anything specific.What pointless video features would that entail?
It’s not reserved to the R5 II and R1, it’s “cameras released in June 2024 and onwards”Or it's still reserved for R5 II and R1?
