Pentax 50mm 1.4 lens...opinions

What do u guys think about the Pentax 50mm f1.4 ??? i have a friend that is not using his lens and he is selling me that lens at $200 ... perfect condition.. i have seen that one for around the $400 new... .... actually yesterday i saw some reviews compared with the Sigma 30mm f1.4 and most of the people said that the Pentax gets a better image...

There are LOTS of different versions of "the" Pentax 50mm f/1.4. Do you mean the SMC Pentax-FA 50mm f/1.4?

Both, the late FA 50/1.4 (AF) and the much older A 50/1.4 (MF) are great lenses. The contrast goes down a bit wide open, but overall the image quality leaves nothing to be desired. You just need to accept the inherent limitations such a fast lens obviously has. I find these lenses indispensible, even on a current DSLR. But ofcourse opinions differ on this.

200 bones is a reasonable price for the FA version in good condition. Its a fun lens too. IMO 50mm shoots a bit long for candids around the house though... in the club setting I imagine it could be tough to get a clear shot of more than a couple people together. I'm on the hunt for a reasonable 28 up to 35mm prime...
For example, I didn't crop the following, and my back was against the wall.. I couldn't get any further away due to the space limitations, a 30 would have been perfect. Looks soft because I had it wide open trying to capture the stage light. Big apertures takes some getting used to.

ISO: 800
Exposure: 1/80 sec
Aperture: 1.4
Focal Length: 50mm



If you have room to move around, and you can stop it down, the FA50 is very good..

ISO: 100
Exposure: 1/2000 sec
Aperture: 2.5
Focal Length: 50mm

I had FA-50mm f1.4 and sold it off as I didn't use it a lot. I found that 50mm wasn't really good for me to take indoor shots with 2 year old daughter. I found myself using 16-50mm more than 50mm f1.4.

I'm actually thinking/debating about DA 35mm macro or DA35mm f2.4. Maybe end of this year or next year, as I bought K-5 couple of weeks ago (without the boss's approval hehehe).

I use the Voigtlander Nokton 58mm f1.4, and I can recommend it very strongly. Very ice IQ. Extremely sturdy lens. Highly recommended to anyone who is not afraid of MF.

Voigtlander stopped to manufacture its lenses with K-mount and this lens will become a classic...

well .. yes the one that im talking about is the FA 50/1.4 (AF ) .. basically i found a Vivitar 28mm f2.8 to shoot people indoors.. so i think im ok with that... and i was looking for a f1.4 lens to shoot some little club videos and catch some good light...

I saw a video that somebody did in a club with the 50mm 1.4 and looks pretty good to me.. but i also read about the Sigma 30mm 1.4.. that compare with the $200 ( price im getting ) Pentax is more expensive... mmm

At that price, buy the FA50/1.4 and see if you like it. You can probably sell it for $100 more and get the Sigma.

I find myself in a very similar position. Trying to take indoor shots of a toddler with the FA 50 1.4 is not easy.

On the other hand, it performs marvelously with a 3-month old (they don't move around so much).

Has anyone compared the sharpness of the new DA 35 to the 50 1.4? Ideally I would sell off the 50 for a better focal length, but not if I have to sacrifice IQ. Not sure I can justify the cost of going to the 31 limited, which would probably be the best solution.

As always, there are dozens of existing opinions and sample images from all of the aforementioned lenses all ready for you to read in the Lens Review section of this site.

I'm REALLY curious about this as well. I have some work coming up that would fund the DA35 and I really do like the look and idea of getting a "true" 50mm focal length, but I had a great experience with the FA 501.4.

I rented the 50 for a wedding I did (as a favor) in March. I really fell in love with primes with that lens. I found myself backing up (often into the wall) quite a bit for shots like these:

f1.4 1/60 ISO100

(No PP on this shot, just a combo of bokeh, flash, and warm WB)

I have heard that the 50/1.4 is a bit soft wide open but I kept it stopped down to at least f2 most of the time. Here are a couple at F2:
1/400, ISO 400

1/160, ISO 160


While I loved the 50 1.4, I would love to hear how the DA35 stands up. I have heard that it's optically identical (or extremely similar) to the FA35 f/2, which currently fetches about double the price.

From what I've heard, though, if you're going 50mm, the 1.7 is a sharper lens. I don't know what pricing for the 1.7 is like though.

first lens i bought was 50 f1.4 and 50mm isnt the best length for walk around, always need more distance etc and at f1.4 to get focus at exactly what you want is a killer, but about to return my tamron 17-50 2.8 and what i can say, its a different league, 50mm is faster sharper, and small and light, when you learn how to use it, its a brilliant lens.

50mm isa good lens, takes some skill to get the best results. MUST use a good or you won't really experience the IQ of this lens (will look low-contrast).

Best bang for the buck lens in Pentax land at 300 dollars. For 200 dollars you should jump on it.

Pretty flexible, portraits / snapshots / low light / landscapes. It's not going to do everything, but it does what it does well.
