The price of 35mm always goes up around this time of year for two reasons, students taking photography courses and people wanting extra cash for the holidays. I have seen some ridiculous prices on Craigslist, 350 for a 50mm 1.4 non-AI, 1500 dollars for a Canon F1 with a motor drive. Get the hell out of here.
Best time to shop 35mm is right after the holidays people are looking to unload after running up credit card bills and needing to pay them off quickly. Look for your OM then.
