I suppose this wasn't a very fair comparison after giving is some more thought. They were shot with different cameras, different ISO's, different shutter speeds and slightly different PPing. So.... Jeez, how on earth could I expect them to be "the same" or even close to it? I guess what I was trying to demonstrate was the remarkable sharpness (at least to my old, tired eyes) of the old $12.00 Vivitar lens as compared to the more expensive, highly thought of Pentax lens. Not that I'm putting down the Pentax lens by any means. I like it a lot, but, as the phrase-de jur goes, "just sayin'....."

M50 1.7 and an electric fan with not quite enough power to blow my hair the way I wanted it to.

Let's throw a M200/4 image into the mix. Something appropriate for Valentines Day.

A great old lens. I must get mine out and use it more! Love those old Pentax manual lenses. Such quality build! Sturdy, built to last for ages!

I have owned a M50, f:1.4 for almost 50 years.... first a M42 version for my Spotmatic, then switched over to a bayonet mount in the 70's Still have it and it STILL kicks butt! But, I must say, I'm growing more fond of my new DA 50, f:1.8 every day.


Nice photo of your brother.

Dewman, how nice is to hear that you've owned two versions of the M50/1.4. I guess you first had the Takumar 50/1.4 and then the K or M copy ... I am pretty happy with my M50/1.4 ... You know, not all of us had the chance to win the DA50/1.8 , ja ja ja .... You must show us some of your pictures !!!

Yes, my first was indeed the Takumar and my current one is the M version. The DA 50 has taken the place of my f:1.4. I didn't think I'd ever say that, but the sharpness and color saturation of the DA is out of this world! Here's a sample of what I'm talking about.

That picture is very, very nice and very, very sharp ... It really proves the strenght of the DA ... But you know, I have the DA 35/2.4 and the Takumar 35/2 and I prefer the last ... And my M35/2 is on the road to me ... We'll see. Anyway, your picture is stunning ...

By the way, this is a picture of my daughter taken with M50/1.4

Your daughter is a gorgeous young lady, sir. The image quality produced by your lens is amazing, but then again, it IS a Pentax-M 50mm, f:1.4! It's legendary for a reason, eh? Very nice bokeh and color saturation. How long have you owned it? Have you ever tried using a reversing ring with it? It's capable of producing some amazing macro images, at least 1:1 if not more. Here's a shot I took last summer with mine.

You should be showing us your marvelous pictures more often !! And all the tricks involved in !! I've heard about this reversing but I never had view such a detailled macro photography with the M50/1.4. I will definitely looking for this reversing ring ... and tried to get such a good pictures as yours ..., even if I am quite new in photography. I really started one year and a half, and I owned my M50/1.4 less than a year ... So I don't want to easily replace it even if there are better options like your DA50/1.8 ... And thanks for the compliments to my daughter ...

By the way, a flower shooted with backlight with the legendary, as you said, M50/1.4 (I didn't need to do PP):

Beautiful shot, Jorgario. Amazing color and sharpness. For a guy who's only been into photography for a year and a half, you're producing some wonderful imagery. Very nice bokeh and your DOF is perfect. Nice composition and lighting, too. Bravo.


Reversing rings can be found on eBay for less than $5.00 and they're quite easy to use. Like all different facets of photography, it will take a little experimentation, but it's pretty simple, actually. I would suggest that you try it on a bright, sunny day. Good luck and please, show us your photos.

Reversing rings are the best. As a rule of thumb, the magnification (which is fixed - the focusing system does nothing) at the registration distance (mount to sensor) is in inverse proportion to the focal length of the lens.

A 28 mm on full frame (film) example was when a co worker had a dispute with a jeweler who had resized a ring and basically trashed it. She asked if I could help. I mounted the M 28/3.5 reversed on a 49-52 step up with a 52mm reversing ring on my KX (film, guys). Measurements give this rig about 2.1X measured on the slide or print without magnification, a bit more than technically correct because of the extra thickness of the step up ring. We printed an 8x10 showing the gouges he had done. In small debts court she held up the print and the jeweller caved.

The formula works out pretty closely to the ratio of the lens to 55mm. Adding a bit of extension will increase it.

When using reversing rings, you run out of depth of field right away. There isn't any to speak of. This is a rig that needs stands, lights and tripod. To get enough depth of field to show the file marks in the gouges the lens was stopped down to f/22 while using portrait lights at 45░ from either side with the ring held in a vise.

Thanks to both of you, and coming down to earth, I just want to post a recently developped picture shooted with M50/1.4:
