85mm used to be my favorite portrait FL on Canon FF, so my hunt for the best 50mm on K5 begins. Currently I have only the A 50f1.4, so I shall start with this.

A 50f1.4 wide open on K5 shot in raw converted in Lightroom 3.3 and resized in Adobe photoshop.



Same lens at f2.8.



There are many 50mms so I will appreciate if you can post some portrait shots of your favorite as it will greatly help me. You can also include 55 and 58mm. Thank you all.

Hi Anthony, perhaps you could define what your criteria for "best" is, so the Pentaxians here can help you out. For me, best has to do with size, reasonable sharpness at F/2.8 (F/1.4 has too narrow DOF for my uses). I don't really care about bokeh and all that.

Perhaps I'll leave it to Fengwei and some of the rest to show you the 50mm f/1.2 - think it's MF though.

Some of my shots with the 50mm FA F/1.4 for your use, it is my cat lens... And occasional I use it to shoot my loved ones. These days it's mixed with the 35mm f/2.4 - so cheap, yet quite a good performance, and way lighter. The 50mm f/1.4 still has a place in my bag though, that's for sure. It's sharper from f/2.0 onwards.

Just a few of my fiancee... Please don't quote, I'll remove these after a while, just a personal policy regarding such photographs on CS.

(removed - TS can contact me if he wishes to view them)

Thanks for kind understanding in advance. Perhaps TS could acknowledge the perusal of these so I can remove as and when appropriate.

Thanks JK, I saw the thread but I would like to concentrate on the 50-58 mm FLs. I have the FA31 and 77 fixed. I want to look at these first.
Are you talking about Canon 50-58mm FLs ? I think they do not fit the pentax... unless they are modded. I am holding on to a Canon 58mm FL... but cannot test.

Thanks and appreciate your contribution. I am only interested in the 50-58mm FL range, Pentax and M42 mount only.

FA50 f1.4. I read somewhere it's among the best of the 50 f1.4 lens which every brand has..

My example here.

Hi, I don't understand what you mean, 50-58mm focal length range, Pentax and M42 mount - doesn't the 50mm f/1.4 FA fit this????
he is only interested with Pentax 50-58mm FL range lens? i am just guessing

Yes FA 50f1.4 is within the 50-58mm range. Meaning, I want to see only Pentax or M42 mount lenses such as the 50f1.7, 50f1.4, 50f1.2, 55f1.4, 58f1.4. There may also be some odd 55f1.2 which I will like to look at also. For other focal lengths I am fixed with FA 31f1.8, FA 77f1.8 and K 135f2.5. Thanks for your help, and I appreciate your FA 50f1.4 images.

http://www.flickriver.com/lenses/pentax/ --> May be useful, show photos by lenses.

Here's another of mine:


Just looked through my portrait gallery again (http://lepetitphotographe.smugmug.com/Portraits/People/7747675_h9TWQ#1191557033_a6NCH), and am surprised there're hardly any FA50mm shots. Most are taken by the DA70, with quite a few by the FA43, DA35 Ltd, and even DA21. I didn't realise how diverse they can get..

I don't know which lens is the best. Each lens has its own characteristic IMO :bsmilie:

Super Takumar 50mm f1.4 (8 element)


K 50mm f1.2


Revuenon 55mm f1.2


K 55mm f1.8


All shot wide open with K-x in jpeg mode.

I always missing my M50 f1.7 after used for about 2 months and sold it away, if there is a chance I'm sure I will get it back, probably the F50 f1.7. Below are some of the photos taken with the M50 f1.7:

I think so as well. :)


But this lens has character

Revuenon 55/1.2


The most ordinary things become something special for this lens.
