SMC Pentax-M 1: 3.5 135mm Asahi Opt. Co., Japan is a very compact 135-era film camera for Pentax cameras. The lens uses manual focus, on original Pentax cameras automatic aperture control is possible (automatic setting at the time of shooting).

The 'M' prefix in the name of the SMC PENTAX-M lens denotes a new generation of lenses with the Pentax K mount. The lenses of the new (for those times) line differed from their predecessors in more compact dimensions.

History

There is a huge family of Takumar / Pentax class lenses 135/3.5:

  1. Takumar 135 / 3.5, 1953-1957, diagram 5/3, model in silver / metal case
  2. Takumar 135 / 3.5, 1957-1961, diagram 5/4, model 324 and 43240
  3. Auto-Takumar 135 / 3.5, 1959-1963, schematic 5/4, model 343
  4. Takumar 135 / 3.5, 1961-1966, diagram 5/4, model 353 and 43530
  5. Super-Takumar 135 / 3.5, 1963-1965, schematic 5/4, model 354 and 43540
  6. Super-Takumar 135 / 3.5, 1965-1971, scheme 4/4, model 43541
  7. Super-Multi-Coated-Takumar 135 / 3.5, 1971-1975, schematic 4/4, model 43542
  8. SMC Pentax 135 / 3.5, 1975-1977, schematic 4/4, model 23440
  9. SMC Pentax-M 135 / 3.5, 1977-1986, scheme 5/5, model 23460

Later the 135 / 3.5 line evolved into the Takumar / Pentax line 135/2.8:

  1. SMC Pentax-A 135 / 2.8, 1983-1989, schematic 4/4, model 23497
  2. Takumar Bayonet 135 / 2.8, 1984-1987, schematic 4/4, model 23437
  3. SMC Pentax-F 135 / 2.8 IF, 1987-1991, schematic 8/7, model 23417
  4. SMC Pentax-FA 135 / 2.8 IF, 1991-2000, schematic 8/7, model 23427

Takumar / Pentax lens line is located separately 135/2.5:

  1. Super-Takumar 135 / 2.5, 1965-1971, schematic 5/4, model 43801
  2. Super-Multi-Coated-Takumar 135 / 2.5, 1971-1972, schematic 5/4, model 43802
  3. Super-Multi-Coated-Takumar 135 / 2.5, 1972-1975, schematic 6/6, model 43812
  4. SMC Pentax 135 / 2.5, 1975-1985, schematic 6/6, model 23840 (two sub-versions with different spelling of the lens name)
  5. Takumar Bayonet 135 / 2.5, 1980-1988, schematic 4/4, model 23830

And there's another Pentax lens on the side. 135/1.8:

  1. SMC Pentax-A * 135 / 1.8, 1984-1989, schematic 7/6, model 23530

Lens hood telescopic, built-in, metal with a decorative ring for a comfortable grip. The hood is firmly fixed when unfolded.
Manufacturer country LENS MADE IN JAPAN
Period presumably from 1977 to 1986

The lens is perfectly assembled. The lens came to my review in a stylish wardrobe trunk with velor interior trim. The focus ring is rubberized and rotates 220 degrees. During focusing, the frame rim lengthens, but the front lens does not rotate. Focusing occurs by moving the entire lens block relative to the frame of the housing.

The lens is sharp enough on F / 3.5, but I have seen much sharper 135-tki. If you cover the aperture to F / 5.6, the lens becomes very sharp. SMC Pentax-M 1: 3.5 135mm well tolerates back and side light, has a simple bokeh, nice color reproduction and moderate contrast. A noticeable drawback is the excess of chromatic aberration. In general, as usual, from a small maximum aperture of F / 3.5 I would like a little better sharpness indicators.

I used the lens on the camera without any problems Sony a7 using the Pentax K (PK) to Sony E adapter. Source files can be downloaded at this link (35 photos in '.ARW' format, 792 Mb). Part of the photo was shot in APS-C mode (crop with Kf = 1.5x, for those who want to understand how the lens works on crop).

Oh yes, I think the SMC Pentax-M 1: 3.5 135mm Asahi Opt. Co., Japan and CANON LENS FD 135mm 1: 3.5 (from the previous review) technologically better than the Soviet MS Jupiter-37AM 3,5 / 135but I like Jupiter-37 drawing more.

Comments: 48, on the topic: Overview of SMC PENTAX-M 1: 3.5 135mm ASAHI OPT. CO., JAPAN

  • Yuriy75

    The question of comparison with Jupiter 37A is open, the author carefully conceals his opinion. (Apparently Kiev flea markets Arkady pay extra for advertising antique optics :))

    • Yuriy75

      Overview as always on top, beautiful photos! Thanks from all readers!

      • anonym

        So it’s very interesting to me that you read the review or are kidding. Well, it’s not so, comrade.

    • Arkady Shapoval

      C'mon, in this review everything is indicated both on the Yu-37 and on the previous Kenon. Just read it carefully.

      • Yuriy75

        I'm sorry, I joked unsuccessfully.

      • Rodion

        Yes, Ernostars merge in front of the Sonnars according to the drawing.

    • Alexander

      Yuriy75 Are you all the time so not attentive !? And you blame the man for something.
      Not good and not beautiful.

  • Olegjan

    Very boring lens, no words.

  • Artem

    I would like to see a review and hear your opinion on the Nikon 70-200mm f / 2.8 VR II lens

    • Lynx

      send it to Arkady for review and he will gladly do it.

  • Alexander

    I liked the review!
    And in it I got an answer to my curiosity.))
    Keep it up!!!

  • Lynx

    dya ... not Jupe, not Jupe ...

  • Rustam

    Summer, heat - it's time 135-current

  • anonym

    Yu 37 A, especially the MC version, drives. It has one "drawback" - it's painfully cheap.)

  • Dmitriy

    I once had a Takumar 135 3.5, nice focusing, then I bought a CZ Sonnar 135 3,5 Mc to replace it, it was just fabulous, the bokeh, the back was excellent, for sunsets it was the same, then I bought a Canon 70-200 F4 and I was disappointed, it gives very ugly glare when shooting a sunset, the only thing is sharpness and constructiveness at a height. And of course my ideal 135-k is Sonnar 135 3.5 ms

    • Rodion

      Sonnar did not have the honor to use, but purely from the drawing - my favorites are Jupiters. And helios.

  • anonym

    And I am from Tahir-11 white trudge))

    “Oh yes, I think the SMC Pentax-M 1: 3.5 135mm Asahi Opt. Co., Japan and CANON LENS FD 135mm 1: 3.5 (from the previous review) are technologically better than the Soviet MC Jupiter-37AM 3,5 / 135, but I personally like the Jupiter-37 drawing better. ”

    This is the very phrase that you always want to see in a review, namely a comparison, because any thing can be described as you like, but everything is learned in comparison. Thanks to Arkady for giving a comparative analysis with analogs, so most "professionals" find it easier to navigate the models, of course, it is sometimes difficult to give an unambiguous assessment of the optics, for example, everyone likes bokeh differently, but the assessment of sharpness, contrast, resistance to direct and lateral light sources , the opportunity to catch hares can be given. And when this is also given in comparison, it is generally wonderful. Personally, I did not shoot with such a lens, but from the review it is clearly clear to me that it is more technologically advanced than the Yu-37, which I was shooting with, although I still did not understand about the sharpness on the open OH / Yu-37, which one would be sharper? it would be very cool if there were photos of the WORLD on different focal points, if the object is zoom, and on different “darks”, it would be possible to compare the raves of the WORLD, see the sharpness in the center and around the edges, see distortions and, say, compare with the raves of your lens, I think that would help many people when buying another lens.

    PS Thanks to the author for a good review.

    • Yuriy75

      I think it will be too much with the worlds, but the author’s opinion is more valuable to us. Sometimes self-hypnosis helps cooler than drugs. I think the main attitude in any business. Sorry if I offended anyone.

  • Oleg R

    By 135 kams I have an old love !!! Tair-11 is still intact. From Kiev-19 he moved to Nikon D7100. The quality is as always on top. Generally a convenient size…. Both a portrait portrait and a small one ... but already a telephoto camera ...

  • Dmitriy

    Good day!
    Thanks for the great review, Arkady!
    I read it with pleasure and agree with you about the Ju-37 - I also got used to it :)
    So I think, is it worth it to buy the MS version over time or not?
    And as a pentaxist, it would be interesting to compare them of course. Moreover, their price tags are similar.
    Looking forward to new reviews! Good luck to you!

    • Rodion

      The MS version does not say much better than non-MS. You need to watch with tests of specific samples.
      As for the takumars and pentaxes, these are all Ernostars, they give a more “triplet-like” picture, and the old non-MC Ernostars may have poor contrast. Ernostar has more than 8 glass-air surfaces, while the zonnar has no more than six. That is why old white Jupiter-9 can have quite good contrast in the absence of normal enlightenment.

  • anonym

    This Nex gives a disgusting picture, doesn’t anyone see it, everything in the photo with children is very colorful, my 20d canon gives much more pleasant colors and the picture is neutral like a bw film

    • Arkady Shapoval

      You are probably paid extra so that in every review with sony a7 (ILCE-7, they removed the name NEX from this camera) there is a comment about the godly color. Calm down and continue shooting at 20d in b / w mode)

      • Rodion

        To be fair - in the review of the old shoe 135, the colors were completely unnatural. I hope this was just an annoying mistake. Here the colors are beautiful and natural.

        • Oleg

          Not really Arkady in the previous review, the colors were more saturated, in this they are more natural. Is this a property of the previous lens or camera settings?

          • Arkady Shapoval

            In the previous review, the camera jeep is in 'DEEP' mode in this review with the 'Portraint' setting.

            • Oleg

              Got it

  • Anonymous from anonymous

    I suggest a friend throw in a new monitor so that he can perceive colors normally, otherwise he can only view the photo in b / w))

    • Yuriy75

      Maybe it's just that the "game" mode is turned on in the engine settings, which increases the brightness and saturation of colors, it is probably worth switching to the "standard" or "text" mode. :)

      • Yuriy75

        monitor

  • lite

    Tell me, if I install such a lens through an adapter on a Kenon crop, will the jumper interfere with the mirror?

    • Ivan

      It’s funny.

    • Passed by .......

      Yes, yes, yes, it will throw up a little when walking. The way out is just a tripod and no mirrors. Especially after midnight !!! I recommend covering everything that is with rags and burning candles without turning around. And yes, the most important thing - more onions!

  • anonym

    I have such a question, tell me why there is a white-yellow convex mark on the lens body, where the hyperfocal distance scale is, a little further to the side, above the number 32 (you can see it clearly in the upper picture)
    it is available on all old lenses, but somehow I didn’t notice on new ones

    • Arkady Shapoval

      This is a common bayonet mount label. You need to match this mark and the mark on the camera mount, then rotate the lens until it clicks.

  • anonym

    I have two "old" manual lenses, yeah, everything is as usual, you combine two red dots, where the camera and lens mount itself is, and this convex mark ... it does not coincide at all with the red currents, this is ... I am not catching up) ... for what? if there is one red dot on the lens, and the other (reciprocal) on the camera mount ... I can't understand why, you can certainly not bother, but it's still interesting ... I've just rotated the lens again, no ... it doesn't match ...

    • Arkady Shapoval

      I wrote to you for yellow, I can’t understand what it is about

  • anonym

    Well, yellow, spherical, so voluminous, in the upper photo it is clearly visible, where there is a scale with hyperfocal marking
    this yellow drop-dot does not match the red mount marks

  • anonym

    maybe you need it to install (remove) the lens in order to rest your finger on it? something has never used it ... yes, probably for this ... if so, then it is located on the uncomfortable side

    • Arkady Shapoval

      This is a sticky lens for mounting the lens. It can be found by touch in the dark, usually it is white or yellow or green (depending on the lens series, A, M, L) so that it can be clearly seen in poor lighting. Also to the touch of the old film cameras (not new), the button for fixing the bayonet was searched. It was necessary to combine this white point with the position of the latch. Later, this protruding point was removed, since the main mark (usually red) is usually enough for everyone.

  • anonym

    Thank you)) and I think, well, they won’t just do it
    as Krylov said - and the chest just opened))

  • Anna

    Good day! Thanks for the review! Tell me, please, what kind of adapter is needed for this lens on a Canon 600d camera. I read about the chip (focusing on infinity), I want to order on Ali, but I do not know the correct name of the adapter. Thanks)

    • Rodion

      Any PK-EOS.

  • Alex

    A very decent lens for the money, it’s a shame to complain too much :)

    Quite sharp when open, I'm not being picky)
