prehistory

At first it was ... Sony. And then I sold it and switched to Canon :). Together with the camera, the glasses were gone, only Helios 44 was left. Since I like to indulge in a subject, the search began for glass that suits this business better than Helios. Preferably not very expensive. After some time, I bought Tamron Adaptall-2 35-70mm F3.5 CF Macro (17A) for 28 bucks + Tamron Adaptall-EOS adapter for 14 bucks.

History

Tamron Adaptall-2 35-70mm F3.5 CF Macro (17A) is a zoom lens for 35mm SLR cameras. Since Tamron does not make its own cameras, thanks to the Tamron Adaptall-2 interchangeable shank system, it is possible to install the lens wherever you want. Fortunately, the flange of 50.7 mm allows you to screw it even on Nikon. For systems from the 70s and 80s, it is possible to find original adapters, for newer systems there is a huge number of Chinese adapters. It is possible to use adapter bundles, for example Adaptall-M42 + M42-the desired system.

Our experimental graduated from 1982 to 1987. Interestingly, there were 3 different modifications and they were all labeled 17A. The first version has a smaller focus ring pattern and reverse focus, like Nikon's. In the second version, the focus direction was changed to normal. In the latest version, purely cosmetic, they only increased the size of the focus ring pattern.
I got the very first version.

The lens lies comfortably in the hand, assembled well, efficiently. Glass, metal and very little plastic. The zoom ring is rubberized, the diaphragm and zoom rings are plastic. The zoom ring consists of two arcs on the sides of the lens. When zooming, the lens lengthens. When focusing lengthens, the front lens rotates. The lens has a wide rubberized focus ring that rotates approximately 330 degrees. The focus ring rotates gently, smoothly, it is a pleasure to use it. Turning from infinity to 0.9 meters takes only about 80 degrees, the rest is close range.

The lens uses a special 'BBAR MC' multi-enlightenment - Broad-Band Anti-Reflection (broadband anti-reflective multi-layer enlightenment). The front lens is cast in blue, lilac, aquamarine, and the rear in lilac. The front lens is also very convex.

Now about the MDF. At 30 mm it is 0.9 m, at 40 mm - about 0.45 m, 50 mm - 0.3 m, 70 mm - 0.25 m. CF in the name of the lens stands for Close focusingthat is, when focusing 30 mm from infinity upon reaching the MDF of 0.9 meters, the focus ring does not stop, but continues to rotate, changing the focal length until it stops at 70 mm and 0.25 m. The lens is capable of capturing macro at a scale of 1: 2,8 to 70 mm.

Now about the problems that I encountered when using on my Canon 60d. First, infinity only focuses on a covered diaphragm. Since the working distance is as much as 50.7 mm, then I sin more likely on the Chinese adapter. A new one will come - I’ll check it. Secondly, the same Chinese adapter does not fully clamp the diaphragm pusher, as a result of which it does not close more than F / 8. The pusher is a small wheel that needs to be pressed into the lens. Again, I’ll think about blocking it with a new adapter. If someone suddenly had an unnecessary Adaptall-M42 adapter lying around - I’ll be happy to get it in my raking hands :)

Image quality and examples

Distortion is very well fixed. Data taken from www.adaptall-2.com: Distortion: 35mm: 2.18% (barrel), 70mm: less than 1% (pinclush.)

Since the lens was primarily bought for the subject and there is no infinity, then there will be no test shots on the street with grass and cats. There will be no portraits, since from infinity to 0.9 m we have only 80 degrees and focus is not very convenient to catch.

The color of the lens conveys wonderful, automatic white balance The camera also works without problems. All test shots were taken quickly at work, with one softbox and on the F / 8 aperture, from editing only exposure compensation in Lightroom during conversion. Also reduced size.

Сonclusion

A lens for 28 bucks for a subject? IMHO is very suitable, for the same money it is difficult to find something else. Even the problems mentioned above do not bother me at all.

  • Pavel Romanenko

    Is such a small flu for the subject a deliberate step?

    • Bogdan

      I wrote that due to problems with the adapter, the aperture only closes until F / 8.
      The adapter that is now, I spoiled a little trying to achieve infinity (in vain I did this, I don't need a lens for infinity). A new one will arrive - I will normally block the pusher and close the diaphragm more. Test shots were taken at 70mm and on MDF, the decorations are small, that's why there is such a small depth of field at F / 8.

  • Bogdan

    I forgot to mention in the review that the 17A is a parfocal lens.

  • Rodion

    As a rule, these zooms are taken full-time. And the topic would just be grass, birds and little people.
    In the photo, the nature of the glass is not disclosed.

    • Arkady Shapoval

      I agree. But Bogdan took many pictures of the lens itself, so I added a review of it.

    • Bogdan

      Using it as a staffer is not very convenient, distances up to 0.9 m occupy most of the focus ring stroke.
      Tonight I’ll try to take some more photos.

    Nah, nobody will surpass Vega 11)
    4 dollars))

  • Bogdan

    A small addition: with a normal adapter, there is infinity, and the aperture closes to the end.

    • Sergei

      Have you tried to shoot the video? How does he sharpen in the middle and far field?

      • Danko

        Sorry, but I sold it a long time ago. I did not need him. Therefore, I can’t say anything else.

  • Ivan

    Great photos on the subject! Pts interesting optical caliper. This is what the photo means when the hands are not from F and the head is in place. 67 lines in the center - very good!

  • Outcast

    Excellent macrush filming and a surveyor nothing. Well done, the author, using a living example, showed how a veteran for a penny essentially taps modern whale plastic one way.

  • Eugene

    I’ll just take a few photos taken on this lens with a Nikon D80 camera.

  • Eugene

    all photos are only developed in c1 and the size is reduced to 2560pcs.

    I noticed that you didn't say a word that this lens is not parfocal. It is very strange that you did not notice this ...
