Having been around at the birth, I can say that from the late 1950s into the mid-1960s, the whole grail sought by all the major manufacturers at the time was the best fast 50mm "standard" lens. The reference to beat was the Leitz Summicron 50mm 2.0. In 1961 (or so), Nikon replaced its doggy 58mm 1.4 from the original NIkon F with its new 50mm 1.4 and claimed best SLR lens of the day. However, those seeking to dethrone the Summicrom had to wait for the first Pentax (Takumar) 50mm 1.4, around 1964. It beat the Summicron, and it held first among equals status for many years thereafter, even though it went through a couple of slight modifications over time.

I feel myself also being on a time travel. When I will go into the older tessars with 2.8 and some of the 1.9/2.0 fifties. I am pretty excited how they will compete. The Summicron 3-cam is the next lens, I just started testing. So I will know the reference to beat. 😎

What is the best Takumar 50mm 1.4? There are so many that have similar names.

@randallstewart1224 Ай бұрын

@@cjewe1z The original dates from 1964. Thereafter over th yers, it lost an element, had its thorium doped "radioactive" element replaced with a newer form of high index glass, and acquired multi-coating. I doubt if anyone can tell an image made from one or another outside of an optical test lab. If I had to choose (I don't), I'd look for a later, muti-cooated version, as the quality of the coatings is likely to be more significant than any other factor.

I love my Pentax-M 50/1.4 on my analogue Pentax SLR bodies. A fantastic lens. Recently I also got the "Thorium" Pentax-K 50/1.4 but my copy also is pretty yellow. When shooting black&white, I don't need a yellow filter ... 😄 ... personally, I'm not overly worried about Thorium lenses but I do keep all these in a separate closet in my hallway, not in my living or office space.

With this 50mm series I started to really figure out how all these lenses behave and what „character“ seems to mean to people. So my favourite before was the canon, because I always only used canon. But the Pentax ist really good and also I find the cameras so beautiful. Especially the old M42 are so nice. No cocking lever is more stylish. 🤩

This is a lovely lens for those who want a vintage look when adapted to digital cameras. I had one myself for a while but in the end I swapped it for the Pentax-A 50mm f/1.7 because it seems to have better contrast across the f-stops and is already quite sharp wide open. Although obviously it doesn't take in quite as much light but I feel it's a small price to pay for a slightly more practical lens day to day. Very nice review.

@manugeee Жыл бұрын

Thank you very much. The 50mm 1.7 is also on my list to review, but will be covered another time. Then I will of course also compare it to the 1.4 -M version. 😁👍

Excellent review. I learned a lot (especially regarding the use of lens coatings). I have a Pentax 50mm f1.4 lens mounted on a Ricoh KR5.

Hi, I've just tested this lens from a reseller and found the focus ring had a little movement when moved left to right (not turned, but moved) like if it was a little loose, and also made a little click sound when doing this. I'd like to know if this is normal or I should avoid buying it. Thank you very much, wonderful review BTW.

@manugeee 6 ай бұрын

Hi Matteo, no, that is not normal. The focusring should not have play. That should be concidered in the price. But it should also be easily fixable. Usually there are a couple of screws, behind the front ring, that maybe have loosened. Thanks for the compliment. :D

Nice review! I just purchased the Super Multi Coated Takumar with Thorium Glass in M42 mount. There seems to be varying opinions regarding whether the level of radioactivity in the lens is harmful, so I'm wondering if you think it would be good to return it and the get the SMC version which is supposed to be non radioactive?

@manugeee Жыл бұрын

Gratulation for your new lens! Did you had a look at the video of @simonsutak? He made a very good one. Infringe what gehe says, the radiation should not be a problem. But I could also just make an „educated“ guess. And I decided for myself, that it’s not worth exposing myself to the radiation. No matter If the concern is dangerous or not. But that’s just my decision for myself. :-)

@randallstewart1224 Ай бұрын

If you are worrying about you radioactive lens, don't bother unlessyou plan to grind up the lens element and spread it on your next sandwich. You'd get more radioactive exposure hopping a round trip to London and back (from the US) than you'll ever get from one of these lenses. Practically all of the radioactive lens scare dates back to the 1960s, where everyione was living with, and afarid of, The Bomb. Back then, if someone said the lens was rdioactive, everyine would dive under their beds. Purely as a matter of public relations, Pentax replaced the thorium doped elements in their lenses (35mm and 6x7) in the early 1970s as new forms of high index optical glass became available. When the subject comes up, most folks think of Pentax, however, nearly every lens manufacturer used thorium doped lens elements in the 1960s. Other makers were just quiter about it.

i got one of this lens to use with my Pentax LX body. By comparison with my Nikkor 50mm 1.4 ais and my Canon 50mm f1.2 fnd, i found this lens a dog. It really never gets sharp. I liked the colour rendition but the lack of resolution makes it unusable imho.

@manugeee 4 ай бұрын

Hmm… maybe you had a bad copy? Once I had a EF canon 50mm 1.4 which was soft all the way. Even with manual focussing with a mirrorless camera there was no sharp spot. On the other hand the Nikkor is also really nice. The canon I don’t know (yet). 😈😈😈

@@manugeee Thank you for your response. Really appreciate your work and videos. I ve been collecting film cameras and lens for +20years. This pentax SMC 50mm F1.4 M is the lowest resolution lens I ve came across. Even against my old nikkor rangefinder lens from the 50s...I don't really know what a bad copy means. There might be some variation across lens but it shouldn't justify something in particular. Interestingly, I love the colours, contrast and overall rendition of this lens. I also like the feeling and build quality. Even more interestingly, I find the performance in low light at F2 quite good but the the lens never really gets sharp. I just created a flickr account and upload three test rolls for you to see, in case it interests you. Just random photos to try the lens one more time.

I could ask, why you have so many lenses, but I totally know. ;-) With APSC 35mm are really a better choice. It’s all about the angle of view. :-)
