I am using my FD 50mm 1:1.4 lens (with silver ring) since thirty years now and I am happy with it. I will get a used 50mm 1:1.2 (no SSC) as a set with a F-1n I will buy next week. The 1:1.2 lens seems to be a newer one as it has no silver ring.
How do those two lenses compare? Is it worth keeping the 1:1.2 or should I sell it? How important is the "aspherical" with the 1:14 lens compared to the lens without?
What do you suggest?
Thx, Chris
If I'm not mistaken the 50mm f/1.2 "new FD" lens (which I think is what you're talking about) does not feature aspherical elements. There is a 55mm f/1.2 AL, and of course the 50mm f/1.2 L that both have an aspherical front element.

The "new FD" 50mm f/1.2 has an optical design very close to the standard 50mm f/1.4, but new glass types allowed it to have a larger aperture and still maintain good image quality wide open.

I dare saying that it's probably not worse than your 50/1.4 SSC, but also faster, lighter and less bulky. I'd probably not sell it. Don't worry about the lack of "SSC" marking on the lens, the "new FD" type lenses all have the "Super Spectra Coating".

I have both the 50mm f/1.4 S.S.C. and the 50mm f/1.2 FDn (non-'L' version). As far as I am concerned the newer style 50mm f/1.2 is over rated. Sure, the f/1.2 is faster than the f/1.4, but only by 1/3 stop. This is really not enough to make a noticeable difference for the average photographer. And the bokeh 'technically' would be greater with the f/1.2 when compared to the f/1.4. But again, probably not enough to be noticeable to the average photographer.

I like the feel of the f/1.4 better than the f/1.2. Actually I like the feel of most of the S.C. and S.S.C. lenses when compared to the new FDn style. I think they feel heavier and more solid..

But this is all my personal opinion. Make some test shots with both lenses and see which one you like better.

I have a 50mm FDn f1.4 and a 50mm FDn f1.2. I shot it side by side and you wont notice the difference at 1.4 or 1.2. I think the 1.2 is sharper at 1.4 compared to the 1.4 open at 1.4. Colors are identical.

Here are some shots from a 50mm FDn 1.2 non L on my nex 5

this is from a FDn 1.4 , sony nex

Would anyone be interested in a Canon FD 50 mm 1.2 L. I just happen to have my bag gathering dust due to the fact that I have a crop sensor t3i and to use the FD lens needed a converter with a 1.4 multiplication factor making it a telephoto and I'm.looking more into.wide angle at the moment. I'm.looking to buy a 5D classic with the money.

I'll take it if it's free? Because it's against Flickr's rules to sell stuff in groups. If they catch you then you risk getting your account deleted.

Hi, I joint the group justo today, sorry I can see the feed is a few year old already but since I just order two lenses from Japan seller, it will be my very first experience with canon FD, I have vivitar and some minolta beside some modern ones, but I even thinking on selling them and use only vintage! :)

The lenses are pretty similar and I was wondering if I should cancel one of them :S
50 mm 1.4 nFD and the 55 mm 1.2 SSC(bigger and older). I will use them on sony a6000 with speedbooster turbo II so both of them will even come more faster lenses and a real 50 mm on my crop sensor.

Hope to be posting some pictures from them very soon and maybe will decide if I will keep them both or keep just one.

Some of you with those two? did you keep them both or not?
Many thanks

I have used both before and over time I ended up getting the 55mm 1.2 SSC. I picked the 55mm mostly because I have a crazy for fast glass and I have a strange love with the breech lock mount. I don't think you'll find the image quality to be lacking on either of them. So i would say this if, size and weight is a big concern to you pass on the 55mm (plus the extra 1/3 stop of light isn't really much). I've never really heard anything bad about the 50m 1.4 and just about all the people I know that shoot FD lenses has one.

If you need examples I suggest going to the photo pool and use the search box to find images using each lenses so you can get a taste of their characteristics.

Thank you for your reply, I will check them once arrive, not only for their performance but size, weight etc. About the speed I actually have a speedbooster turbo II, so the 1.4 will come near 1?...

I'd personally take the Canon FDn 50/1.4 over the 55/1.2 SSC, mostly because of size and weight. The half stop between f/1.4 and f/1.2 in terms of both light gathering and DOF is minimal.

An f/1.2 wide open lens usually has a somewhat different look than a f/1.4 wide open - typically there's more SA, more vignetting, weaker borders, and stronger cats eye with the f/1.2 lens. These things can be good or bad, depends on what you're going for.

I don't have an FDn 50/1.4, though I'd love to get one at some point. I have a FD 50/1.4 SSC in excellent condition, but don't use it often. I wouldn't mind the lower weight and smaller size of the FDn. My FD 50/1.4 is the sharpest wide open of my the handful of 50/1.4 lenses I have and is corner to corner sharp by f/4. It's pretty impressive. It's sharper wide open than my Zeiss (C/Y) 50mm f/1.4 Planar. Even so, I don't use it that often.

Regarding the Speedbooster/Lens Turbo - yup, adding the focal reducer changes the lens to a 36mm f/1.0 APS-C lens. DOF and field of view will be similar to what you would get with a 50mm f/1.4 on FF.

FWIW, anything faster than f/1.2 doesn't get you any additional light on digital sensors. That doesn't matter if you're chasing shallow DOF rather than low light, though.

Ran into this review looking for weights, might be interesting:

Many thanks for your reply diogenic.
Just today I receive the 55/1.2 and expecting to get the 50/1.4, I want to try them both and I'll sell the other one, of course the 55 was much more expensive, let see, I really don't care so much the weight , the a 6000 is already really light and small.

I think with the 55 Im getting 59 mm aprox. Is something like this right? 55*1.5 / .72.
Also somebody not into photography gift me a rokkor 50/ 1.4, I will try that also when on my hand.

"FWIW, anything faster than f/1.2 doesn't get you any additional light on digital sensors."

I'm not saying you're wrong, just that you've exceeded what my college physics class taught me...
