A further addition to the Zenit story. I thought I needed a couple of extra lenses so having browsed the internet for good value second hand M42 lenses I discovered Ronald White at hhtp://www.ronaldwhite.co.uk . You have to phone him. So I bought a Bell and Howell zoom 80-205mm and a x3 Helios Automatic Teleconverter. I haven’t tried the latter yet but the zoom seems to work well. I agree with people’s comments that the Zenit really makes you learn photography. I have clearly been spoon fed by digital cameras.
The point of all this is that I do recommend Ronald White’s service, prompt, good value, what more can I say.
