Hi, Just a thought, have you tried using one of the Helios viewfinders that you can get for the Russian Rangefinders, I have just tried one on my Zeiss Ikonta 6x6 and it is definitely better than the pokey little viewfinder on that, it has the lines for 35, 85 and 135 lenses marked but you can ignore those, and with a bit of practise you should be able to get a decent idea of what will appear on the film. I got my two viewfinders from a camera shop in England, £6 each a couple of years ago and I have seen the same ones on Ebay varying in price from £8 to £20, give them a try. Regards Rob.
