'L' for 'Legendary'? Canon 50mm f/1.0 'L' USM (1989-2002) lens review with samples

A review I've been waiting to make for years. Manufactured between 1989 and 2002, this legendary 'L' lens still commands legendary prices wherever it can be found. It still holds the crown as the brightest aperture autofocus lens ever made, and the brightest aperture SLR lens ever made - yet, it's always had very mixed reviews (most saying that it's rather soft - and those were reviews from the film era). Well, let's see what this copy of the lens can do, at least.
A huge thank you to Park Cameras here in the UK, for their help in loaning me a copy of this lens for a couple of weeks for testing. Check them out:
Web: www.parkcamera...
KZbin: / parkcameras
By the way - I do acknowledge that there's a chance this is not a a great copy of the lens, optically - however, it's very difficult to tell, with so few of them around.
All pictures taken by me on a Canon EOS R camera (and adaptor). By the way, I did do a little sharpness test on my old Canon 6D to make sure that Canon's EF - RF mount adaptor wasn't causing problems with image quality, and the results were what you would expect, so, nothing wrong with the adaptor.

I don't think it's so much viable, both because of price and of limitations of the EF mount itself (look at how large the back element is, it even has a cut for the contacts!) It could work out better if they had done just like Nikon with their Z mount, which allowed for the Noct S f0.95 due to being closer to the sensor and with a slighty larger mount

The image quality reminds me of the Nikon 50mm f/1.2 AIS manual focus lens - soft wide open but great at f/2 and smaller but lots of character. Perhaps this Canon EF f/1.0 is more for collectors than photographers though.

[@S3l3ct1ve]

it does look that there is something wrong with this lens copy. 6:24 it does look that overall loss of quality across the whole image is uneven the right part of the whole image does look more blown out and has less contrast, looks like some haze effect there, particularly the upper corner. 6:46 interesting ghosting effect on those black stripes, actually does look like interference of a vignette effect. The center of the image looks like its not completely in focus. It could be due to short flange distance and adapters used, its 1,0f the depth of field is razor thin at this aperture the sharpest point is probably less than 2-3mm wide. Ken Rockwell has a review of this lens on his website and he states that this lens is the sharpest "fast" 50 lens ever made, his sample images does look pretty good, although those images were taken on ~20mpx camera. This lens renders highlights in an interesting shape. And of course the price tag of this beast is spectacular too... I wonder how well it would compare to a canons dream lens 0,95f both of them are in the same collectible/dream like league, although dream lens does not have AF system.

[@caldera878]

I would like to see you test out Canon FD L lenses before Canon went to EF mount. The 85 f1.2 L, 50 f1.2 L, 24 f1.4 L...etc are still commanding steep prices and I like to see how they stack up in your testing methods.

[@NicholasAndre1]

I have one of these. Got a little dust in the periphery inside but overall pretty clean. To my eye it looks quite sharp in the very limited focus plane. It’s often difficult to distinguish the difference between things being slightly out of focus versus the lens being “not sharp.” It requires quite an accurate focus (which the EOS R helps with) and placement is key. Although to be honest, the lens has such a cool and distinctive look to it that the extra stuff doesn’t matter. You’re never going to get an entire face in focus anyways at f/1. Not to mention I can use it to shoot on Cinestill 800t in all but full darkness 😛 For any real world shooting (like low light portraiture) the falloff is quite pleasing and the look is quite unique. People really seem to like the images it produces (even without being clued in to the backstory with a long Nick monologue 😂).

[@princeharbinger]

Neat lens. Adapting I think would be a nightmare. Since that AF chip is attached to the rear element. IMO you could buy the Kamlan F/1.1 MII and a few Sigma lenses like the 56mm F/1.4 for example. Both of which blow that lens out of the water.😉

Huh, I was not expecting the image quality to be that bad. It's basically unusable for anything without serious improvement on 1.4 or 1.8 where you have two lenses for fraction of the price but with way better image quality. I guess they just made it to show that they can. Obviously 1.2 50mm L is better if someone still wants that 1.2, but in most cases that's an overkill anyway.

[@TWX1138]

Nice review, I hadn't heard of this particular lens before. I have a request on future zoom lens reviews, if you're testing if a lens is parfocal please tell us. I'd been struggling a bit with lenses for DSLR video and finally learned what parfocal versus varifocal mean. It would be convenient to know if a particular lens maintains or nearly maintains its focus as one zooms, versus losing focus on the subject and having to wait for autofocus to catch up. In the case of my own lenses, I can see why the Tokina lenses, even with their chromatic abberation problems, are popular with filmmakers. My 12-24mm f/4 appears to be parfocal, I don't seem to lose focus even on manual focus when zooming. In contrast, the Canon 18-135mm Nano-USM is varifocal, but using the zoom controller on its slow speed, the camera seems generally able to maintain autofocus on a subject even as the zoom changes. Likewise my worn Canon 17-55mm f/2.8 isn't parfocal but is nearly so, it does not struggle with maintaining focus during zooms so long as one isn't going from extreme to extreme.

[@Twobarpsi]

What a great lens!

[@pkoeniger]

Hi Christopher, thank you very much for another great review. Although knowing beforehand that I will never purchase this lens, I loved watching your video. I own the 85 mm 1.2 L and love it. In fact, it is (next to the Sigma 135 mm 1.4) my favourite lens that I use all the time. Do you have any idea why the 85 mm is so sharp while its smaller brother does not live up to this level?

[@christopherfrost]

Telephoto lenses are far simpler to design than wide angle ones (but more expensive to manufacture)

[@JimBailey]

Thank you Mr Frost.

[@panio84]

2:39 your calculations are right but the light measurement is different to every lens. This is why some lenses like Canon EF 50mm f/1.2L USM has the same amount of light coming to the sensor as Carl Zeiss Distagon T* Otus 1.4/55 ZE Canon. :)

[@sirpetesompra755]

My other question is, with technologies advancing lens will eventually get to f1.0 easily. Will this lens still hold value over time?

All the more why its a collector lens than a useful one. Optical designs today are much better, so better to get something like the RF 50mm f1.2 than this - a half stop less light, but vastly better sharpness.

But I don't see haze. Fungus a bit but no haze. With some image processing I can make it almost match the 1.2 but I wonder, was the copy you tested like this? Do you have raws of the images you took with it posted anywhere? Thanks for all your hard work!

I think the 50mm f/1.2L is a more sensible balance between character, image quality, size, weight and not least, price. In fact, I use mine more often than my Sigma ART, which clearly beats it in the sharpness department. Cool review though!

[@JamesClark1991]

It's great. But it's actually T/1.8 if I remember correctly ☹️

Sure you’re 100% right about the balance... But this lens is not about balance at all, it’s about supremacy. Canon wanted to obliterate Nikon releasing this monster alongside with their new series, while Nikon had nothing even close. As an engineer I revere their feat, especially because there’s still NO ONE can reproduce it’s stats (i mean the AF SLR lens faster than 1:1.2)
