The 50mm Lens Club

There is a lot of discussion on the Forums about 50mm primes, and there is a lot of variety out there in this focal length. It would be helpful to be able to compare and contrast these lenses in order to discover which lenses have the qualities we value. I thought for sure there would be a lens club already for this focal length, but I couldn't find one. So here it is.

Please share photos taken with 50mm primes. Include as many details as you can about the lens and the photo you're posting. Both of my 50mm lenses are fully manual, so I might forget an f-stop, myself.

Here are a few from the well-known SMC-Pentax M 50 f1.4. This lens seems to me to be the greatest quality-for-dollar deal out there. For $50-$70, you get excellent image quality, speed, and sharpness with minimal CA.


Outside on a cloudy early evening. K-7, ISO 500, 1/40s. Around f2.0. I added a bit of softness in Photoshop.




This one is f/1.4, with nothing but one light in another corner of the room. ISO 200, 1/13s, hand held.




And, my other 50: The 50 f/4 Macro:

This one was with a K-x, ISO 200, .6 second, tripod:




The lens is incredibly sharp. You can see the full size original of the following photo at the Flickr page. ISO 200, 1/10s, not sure what aperture. I doubt it was closed down very far, considering the ISO and exposure time.




Which 50s do you have?

There are a number of lens clubs already that overlap with the fast fifties, which already show what these lenses can do, such as this one in your case: The M Club! - PentaxForums.com

Indeed, the M 50 is a fine, classic fast fifty.

Ash, you're right. There are photos taken with 50s scattered throughout the forums. For example, the M club covers only Pentax-M lenses, and it's not specific to this focal length. There are quite a few other 50s out there, and it would be great for comparison to see photos taken with these lenses grouped in one thread.

So, if you have any 50mm lenses, why not post some photos?

I've had a few in my time, but now moved to other alternatives.
The FA 50/1.4 was my fastest and helped me appreciate thin DoF and low-light photography, particularly in the pre-K-5 era...

hi,
do you also consider the 55mm's here? most of the time they go together, just maybe we can consider for the sake of comparison.
thanks

I would say yes. I was thinking about adding that to the top post.

I have two 50mm's - a Sears 50mm 1.7 and a standard Pentax-M 2.0 that came with a K1000 I won in an auction. My 2.0 is kind of... quirky. I've really neglected spending time with it to really understand its inner workings. The Sears lens though is pure awesomeness.

Posted most/all of these elsewhere, but here are some of what I pulled from that $16 lens.

Wow - that cheap Sears is pretty nice.

I'm really enjoying all of the different 50s. boriscleto, what differences do you notice between the 7-element and the 8-element Super Takumars?

Did I mention every one of those shots was taken wide open at 1.7? I love he sharpness of that lens if I can manage to nail it properly. I'm debating getting a better viewfinder just so I can manually focus more easily.

You know, that's one of the reasons I upgraded to a K-7. The pentaprism viewfinder makes a big difference for manual focus. Then, of course, I upgraded to a K-5 because I missed my K-x's dynamic range & low-light capabilities. I considered a magnifying viewfinder, but never tried it. One of these days, I'd like to get a Katz Eye focusing screen.

I have a cheap Auto Sears MC 50 f/1.7 made by Chinon. I paid all of $10 shipped, and I like it better than the M50/1.7.

As far as the 7 & 8 element, I really haven't compared them head to head. The 8 element isn't Thoriated so it doesn't yellow and it might be slightly sharper wide open. I haven't used the 7 element since getting the 8 element.

This was taken with my Vivitar 50mm f1.7 fully manual lens. Not sure my f-stop here unfortunately.
