Hi guys

I'm new to LFF. I recently bought a complete Cambo SC2 in box + 3 filmholders+le ns plate (for 150mm?) for what I though was a bargain (250 euro (say $230). So I decide to try it out and see if I like it and if it is really that good compare d to my 80's Leica R. Now I need a lens for it, do you have any recommendations on what to buy/start w ith?

Also someone suggested to me to use a polaroid back because it will provide both a possitive and negative. Is that correct? Ofcourse I will use some other metho de to make a final print. Might be Palladium or maybe digital (can I scan a 4x5 neg on a flatbed scanner (any tips)).

thanks Reinier
