I am looking to buy a used medium format camera. I am looking for recommendations as to make and model. I have shot on a Lubitel 166 and a Holga 120, so low end toy cameras for the type. I find the focusing of the waist level Lubitel tricky. I would prefer a compact medium format that is through the eye piece focusing. Image right way up with metering on board. For me I simply prefer this way of shooting. I am hoping to find a mid range as far as expense goes $500 -$800 for entire kit. I would love a Hassy but the price point is just too high once you add in all the needed accessories. The other piece is that is possible I would like to be able to change negative sizes, either through the use of masks or different backs. for example 6x6 or 6 x 4.5 . Does anyone has suggestions? Because I'll be buying used looking for a model that is easy to service/ repair and can still find lenses and what have you. Would consider a closed system that does not have interchangeable components.
