After using a cheap crop 35mm for a little time recently I liked the way it made me re-look at things. I did not like the cheap leans and size of the negative. I thought that since I have extra 6x6 cameras I would take one of the Kievs I have and build a mask for the film chamber and another for the viewfinder... ... Not that hard as I can see using thin plastic just like the 35mm cameras use. Any input here?
I have used 35mm in MF cameras and did not like the sprocket holes. I tried to crop that and I found that it just was not right. So using 2x2 to get a center crop where should I go
