Update 02 august 2016 : I have been fortunate to find a few good Tair 3S 300mm lenses, they will come for sale soon, but this time I will keep one for myself 🙂
Look at this test shot I took a few weeks ago, no tripod only handshot, and at full open aperture ! – look closely at the sharpness of the strawberry !
The above picture was taken from the same place as with the Osawa 80/205mm in another album : https://flic.kr/s/aHskePMqnk
Only it was 22:00 in the evening – Shot was taken with a Pentax K5 @ 1600 iso – F 4,5 1/200 straight out of hand.

It was just a shot for testing purposes, but look at the edges on the picture – no distortion.
This is a mighty lens !
A while ago I was photographing seabirds with my Pentax K3 and Sigma 150-500mm F5-6.3 DG APO at Oesterdam.
Today ( 24/06/2015 ) I went again, but this time I took with me my Pentax K5 and the manual focus lens Tair S3 300mm f 4.5.
I just wanted to take some pictures with this lens on a digital camera and putting the lens up for sale afterwards.
I had set the Pentax to 6.3 MP and Jpg, because I probably wouldn’t use them for myself, but just as a selling point.
When I came at home and copied the pictures to my computer, I was stunned to see what this lens was capable of.
I had fired a few dead sharp pictures of flying sea birds.
Not only that, but the Pentax with the Sigma missed so many shots ( flying birds ) with its AF that I had a score of maybe 2/3 out of 10 sharp.
The Tair 300mm had fired at least 7 out of 10 dead sharp.
I am starting to wonder if I should sell this lens or keep it ?
Most of the pictures I took where at F 4.5 and iso 200, all out of hand, and I have to say they are fine.
Focusing is done by a metal wheel in front, this works very fast and accurate. It is possible to modify the gunstock to use it with modern digital cameras, search Google. Here is one : http://www.mig-welding.co.uk/forum/threads/photosniper-modifications.52110/
Originally the lens is mounted on a gunstock and it uses a modified Zenit 12S.
The camera itselves is in working state but misses the iso setting scale plate.
But this can easily be overcome.
The Photosniper set is impressive when you look at it, but the lens is even more impressive in its image quality.
