Desirable 50

I have several ‘A’ 2.0 50mm and a few ‘M’ 2.0 50mm all are ‘clean’ and want to scale down my accumulation. I am wondering if there is some that achieved ‘cult’ status?
Thank you

M 50mm 1.4 is pretty good, so maybe you can trade some for that

I do have a couple each 1.4 and 1.7. Great lenses and yes I have duplicate lenses collecting dust and need to make room for other lenses.

M f/1.7 much nicer than then M f/2 (some of which are downright bad, but there are millions out there). 1.4 is good but not good enough to use at 1.4 for my taste -- 1.7 is best bang for your buck and you can get one for less than $50. There are some very nice Rikenon 50s you can get for practically nothing as well...

Chasing bigger aperture used to be a major passion for me (for many others too).

As a matter of fact, I owned 50mm to 58mm of various aperture and brands. In the end, it is not the aperture size that matters but the "quality" of the images that make the difference. A lot of f1.2 or f1.0 do not produce pleasant bokeh quality at all (individual preference). I just dug out some old photos out and I felt most 50mm behaved the same: same flaws. But 50mm "perspective" is easiest for binocular mammals.

Da* 55mm











What is really good about 50mm is the focal length itself. Then the rest is preference issue: Some like desaturated look or some love the way shadow textures are rendered etc.

Pentax Fa 50mm f1.4 has long standing chromatic aberration issue against highlights in the earlier days. Its bokeh flaws is across the line up of pentax 50mm in general. Well, I would try out the latest version I guess since it is rather a bargain

I don't believe the M or A 50 mm f/2 lenses are particularly sought-after, whether because there were so many of them manufactured, or because they weren't that great, or both. As previous posters have said, the f/1.4 and f/1.7 are different stories.

If it's cult status you're looking for, then Super Takumar 50mm f/1.4, first version (8 elements), SMC Pentax (A) 50mm f/1.2 or DA* 55mm f/1.4. However, as others pointed out, other lenses may serve you equally well if it's optical quality you're looking for. Namely the f/1.7 was better than the f/1.4 in terms of sharpness and spherical aberration during the M and A series, so was the 55mm f/1.8 in relation to the 50mm Takumar/K series. I never had a Pentax 50mm f/2, so I can't speak of its qualities, but they seem built to a different (lower) standard, but that's not because 50mm f/2 is a very common focal length and aperture combination. Leica charges a lot for their Summicron. The Helios/Biotar 58mm f/2 also has a relatively small aperture, but great optical qualities.

I have both an A 1.7 and an M 1.4. As far as I can tell, the IQ is equally outstanding on both. Both are razor-sharp. I use the 1.4 more, though. I like the build quality & it's a tad faster on the rare occasion I need it.

Honestly, if you don't need the extra stop in speed, I've found the 50mm f/2 quite decent.

Some older M50/2s are made in Japan and are built better than newer versions. No one really will pay extra for that. Optically the f2 lenses are all similar. I don't think any have a cult status.

The Pentax-F 50mm f1.4 has some kind of cult status, and is also somewhat rare. The Pentax-FA 50mm f1.7 sometimes sells for a premium over the F version, possibly also due to fewer lenses around. I'd like one for its wider focus ring.

I call it the 50mm trap - somehow accumulating multiple versions, then agonizing over which to keep.

Didn't think about Made in Japan I'll take that in consideration when I sort them out. I'm not sure how I accumulated so many extra 50's, they just appeared on the self.

I was hoping that I had something that was worth more than the average 2.0 50mm.

I have a couple of other brands, Chinon 1:1.9 and Rikenon1:2.0.

With the extra lenses maybe a 'shoot out' is in the future.
If I sell the excess I could purchase a blue-ribbon lens the f1.2 50mm

The M 50/2s are generally worth about $20 -- they were the kit lens for millions of K1000s. An 'A' version probably twice that, although I don't even know if those exist.
