Canon 50mm 1.2 LTM First Impressions – Wading Through The Fog

By Christopher Gio Sarsono

Early this year I had the chance to buy a Canon P for cheap. I had been searching for a fully mechanical rangefinder for a while and this camera popped up during a trip to Japan. I bought it without much thought since it was quite a bargain. But the problem was I didn’t have a lens for it. So the camera just sat at my office for a couple of months. That was until a friend of mine tipped me on a lens for sale, a canon 50mm 1.2 LTM.

It had a couple of dents, and was pretty worn. But he offered me the lens for under 150 USD. The catch? The rear element was badly fogged. But other than that, it was completely fine. The focus was smooth, the aperture clicked nicely and the front element wasn’t as badly scratched as a lot of other 50mm 1.2s i saw.

Now this lens is quite a bit underrated. If you look at the list of canon LTM lenses, the 50mm f/1.2 LTM occupies an odd place in Canon’s lens lineup. The 50mm f/1.8 is the reliable budget option—sharp, compact, predictable. The 50mm f/1.4 earned its “Japanese Summilux” nickname with good reason. And finally there’s the holy grail, the Canon 50mm 0.95 LTM. A cult lens with infamous rendering and a second hand market that commands Leica prices.

And so we arrive at the 50mm 1.2 LTM. As far as my short google searches, it is known to have issues. Especially the rear element that easily fogs up thanks to the oil used in the lenses helicoid. If you’re lucky, it’ll only be a case of a simple clean up. But if it’s been fogged up for a while, there is a high probable chance of it being etched into the glass and coatings.

Sadly that was the case of this particular sample of 50mm 1.2 LTM. But in the end I did proceed to buy it, out of curiosity and an urge to use my poor camera that hasn’t been used. Thinking that I can just sell the lens later on when a better lens pops up.

Fast forward three rolls later, I have developed a love for this banged up, fogged up lens. By any clinical standards, most other lenses I own will blow this lens out of the water. In terms of contrast and sharpness in all equivalent apertures it just can’t match up. But after using the lens, I fell for the ironically imperfect, damaged lens. It’s soft, it’s dreamy, it glows throughout the highlights. There’s a romantic attachment to the lens and how it renders portraits and scenes.

Now this lens would not be my first pick for a landscape or travel lens. But for portraits, contemporary style photoshoots. I’d be more than happy to feed a roll or two through the lens.

It’s not for everybody, and it is certainly a unique look. But my point is that we don’t always need to be clinical photographers, shoot with the best, most sharpest, most pristine and perfect lens. And there are times that the most perfect lens for the job is the most imperfect lens that we own.

I was lucky enough to buy a pristine and clear, 50mm f1.2 a couple years ago for about the same price as you. I couldn't afford the f0.95, the f1.2 was a viable alternative and it rocks! I'm a huge proponent of vintage glass and use older lenses almost exclusively for everything outside of family functions where spontaneity is vital. It acts as a short telephoto on my Leica CL Mirrorless and normal lens on my LTM's and M-mounts, (w/ adapter of course). Great review!

Totally, i love the character from old lenses. Even the sharp ones can make the image glow. It's pretty much gone in new lenses these days. Thank you for stopping by and leaving a comment! Really appreciate it!

Great first article. My copy is currently nice and clean but fogs up remarkably quickly. It only takes about nine months and it needs disassembly. I think I’ll invest in getting it properly cleaned by a professional because the results are good enough to make it worth the expense.

Ah man i hope you can get it permanently cleaned! Even with my unit you can still see how sharp the lens actually renders! Thanks for leaving a reply!

Great article. I have the Canon 50mm f/1.4. It’s especially great for B&W, imo. These old lenses are great fun.

One of my first Leica lenses was a 50mm Summicron with haze and a chipped front element. I thought I needed a perfect one so I traded it off. That was a mistake as I can right now remember a favorite shot I made with that imperfect lens over twenty years ago!

An interesting review of a fast but flawed lens. It reflects well upon the soundness of the design that allows it to perform as well as it does despite fog on the rear element. I have a 50 mm f 1.4 on my Canon 7 and it performs very well. Happy shooting with your interesting lens.

Great article! I have a good copy of this lens and it is indeed sharp wide open. However I recently bought an old Soligor 35-80mm F2.5 zoom lens which has a similarly fogged rear lens element. It only cost $30 and so far I am impressed at how well it works. Love how in some of your shots a very clear sharp area magically appears to cut through the fog and pull in my attention. And that's the fun of using these old "beater" lenses. They do unexpected things which can be perfectly imperfect.

My local shop (Blue Moon) currently lists 48 LTM lenses. They don't have either the Canon f0.95 or the f1.2 but it might be someplace to browse. They are located in the St. Johns area of Portland, OR. https://bluemooncamera.com/shop/category/43/Leica-M39-Lenses/?filters=248&page=2

Looking forward to your next article!

I bought a Soviet era Fed-3 (Leica copy) camera on eBay for $150 including shipping from Ukraine. I didn't want to plunk out the big bucks for a real Leica and I read some good reviews on the Fed-3. The body was in excellent condition, but the lens was not sharp. It wasn't fogged, or scratched, but it wouldn't deliver a crisp image. That put me into search mode for a LTM lens. Ugh! Every one was expensive! Note: There's a ton of Leica bodies out there with no lenses. Lots of Canons too. LTM lenses are at a premium. I decided to take a risk and purchase another Soviet era 50mm lens, in the hopes that it would be sharper. I chose a 52mm f/2.8 lens for $39 plus $15 shipping from a different seller in Ukraine. BINGO!!!! The lens barrel looks rough compared to my first one, but this replacement is SHARP! Not Leica sharp, or as sharp as my Zeiss Contessa cameras (really sharp!) but quite acceptable. These purchases weren't my first venture into vintage Soviet era cameras, as I have a few Mockva 120 folders with great glass and I owned a Zorki that I never should have sold. My guess is that some lenses from that era were made on a Monday by a guy with a hangover and never checked before shipping. A lemon is a lemon, no matter the origin. The lesson: If you need another LTM lens, try Russian roulette.

Nice article, Christopher, and welcome to 35mmc! I too have one of these lenses, and wrote about cleaning it last year [ at https://www.35mmc.com/11/06/2024/cleaning-a-classic-canon-f-1-2-ltm-lens/ ]. I cleaned as thoroughly as I could without completely disassembling and re-greasing it, checked it now after reading your article, and found it totally fogged again. May have to go deeper! Your photos are lovely though, and I will see what mine does on a Fuji X-Pro1. (At least that's a safe experiment, since the lens haze isn't fungus.) Thanks again!! --Cheers, Dave

Sorry... I should've omitted the words "and re-greasing" above. I'd never grease aperture blades! --Dave
