I would select a Canon P- combined VF/RF, parallax corrected framelines, and stainless steel shutter curtains. The modern LTM mount Voigtlander 50/1.5 Nokton ASPH works beautifully with it. The camera and lens would be under $500. A Canon 50/1.8 chrome mount is a safe bet, goes for under $150- so camera and lens would be under $300. For a wide-angle, the modern 35/1.7 Ultron Asph in LTM, or the vintage Canon 35/2.8- same formula as the Summaron. For a short telephoto- a coated Elmar 9cm F4 in LTM is under $100, the Canon 100/3.5- under $150 or so. The Canon has framelines for the 35/50/100 built in.
