ARSAT H 50mm f2.0 LENS NIKON MOUNT helios 81h Not Working in smaller Aperture
Jun 20, 2013

Hi All

Im Venket

I am new to Digital Photography, i have brought new Nikon D3100 now.

Earlier i had Kiev-19 with Arsat H 50mm f/2 lens.

As Arsat H 50mm f/2 has F- Mount i am able to use this lens on my D3100 in manual mode.

Now my problem is this lens seems working only on f2.8 and f2. When i am taking pictures of the same object in same lighting conditions on Aperture f2 and f16 the results are almost same (slightly different).

Upon observing i have found that though i am changing the f no the blades are not closing when f no is changed to 16, as if the f no is on 2 or 2.8.

To check whats happening i have unmounted the lens from camera and set the f no to 16 and then again mounted the lens, while mounding i have observed that in the process of mounting i have observed that the lens blades are opened.

Can you pls suggest on how can i use this lens with full range of Aperture or what is the problem with lens.

Thanks in Advance.

Venket Ramana.

Nikon D3100
