I own the Viv S1 105/2.5 and been having a tough time getting good pictures with it. Admittedly I have used it quite less and that too not for its primary purpose (macro). My understanding is that macro lens are very good for portraits too (albeit sharper). Can anyone tell me if i am doing something wrong here. I have mostly tried shooting at f4/f5.6 and the main problem has been getting the focus spot on (and subsequently sharpness). I use a pentax k-r and try to use catch focus to get the focus spot on

This is a manual focus lens and not sure why you are having focus issues. I often set to manual setting or aperture priority and focus manually. You may want to set to Av in camera and set the aperture to f2.5 manually, allowing the camera to choose a shutter speed but focus manually, turning the lens barrel before triggering the shutter. You should be having a sharp subject and nice out of focus background

Do you have any samples of the pictures?

I used it at an event (night) under tungsten lighting condition, during which i found the issue. I am wondering if the tungsten FF issue in AF (I have a K-r) also manifests when focus is set manually in such conditions (beeping when the camera thinks its in focus (catch in focus), since thats what i rely on) . I later tried shooting some pictures in daylight (macro and portraits) and they came out just fine.


Will post some samples shortly

To answer your question [a few months late], yes - when using CIF, it uses the cameras AF sensors to obtain a focus confirmation and trip the shutter.

Hi all!

I was on flee market this sunday and stumbled across a pentax super me with lens in good condition with manual and sturdy box.

The lens is Kiron 105mm f/2.8 number: 60703010. The women that sold it said it belonged to their father/husband who got it from a dentist company here in Sweden.

I asked for the price for this kit (even an old macro flash was included) and they told me 25 dollar - i took it!

Havent done any hardcore macro yet but tried it out a bit and really enjoyed this lens so far.

A few in camera pp jpegs with K-5

Cat: Got to much light in the camera, just took some brightness down and kind of like this look
The fluffy toy thing is also a self-portrait
The buddah from my garden often get my lenses attention.
