<p>thank you everybody for these valuable responses<br>

as i understand, i landed myself accidentally with a manual aperture lens<br>

i wonder if the 44-4 is better in any other way other than that...</p>

<p>I see.<br>

What is the rule with manual selection of aperture then?<br>

Is it just according to the available light or...<br>

how do the automatic apertures determine?</p>

<p>Does anybody know the difference between Helios 44-4 and Helios 44-2 lenses?<br>

Ive just bought a Zenit 11 at a flea market but changed the lens in the process of purchase from the first to the second because the 44-4 didnt seem to display aperture movement inside.<br>

Did I screw up?<br>

Does zenit 11 and 44-2 work together?<br>

Cheers</p>
