Can I remove dust from my Iskra 2 lens?

When I cleaned my Iskra 2-lens I found out that it has some dust inside it. Did anyone here open up theirs? Should I give it a try or stay away? I am of course a bit afraid to disturb the shutter.

If the dusts are not so many, pls let they be. They will not affect the quality of image.

If the lens construction is is the same as the 75mm/3.5 Solinar on the Agfa Super Isolette, the answer is yes.

The front elements unscrew from inner helical. The rear element, unscrews from the rear of the helical. I use an old fashioned drafting compass with two metal tips to remove the front cells and a lens spanner for rear element.

If I remove the dust I will be able to compare before and after-shots. Then I will know if I need to do it 😉

Thanks! This sounds quite like the big Bessa 6x9 that I cleaned. And that was easy!

Yep, in this case this is a unit focusing assembly, so you will not need to recollimate the lens.

The main thing to cleaning really is to remove any haze that may have settled on the lens.
