In a moment of madness prompted by a thread about the Canon 35/1.8, I thought it might be a good idea to show people where new 40mm filters, hoods, etc. are available. The short answer: Japan. The longer one: set out with risible nerdishness on this sparkling new page. Ugh, it took hours to do and will soon suffer from link rot and general obsolescence. Moreover, I fear that I'm setting myself up for pleas via email: "Where can I get a 54.5mm red filter? I need it for my Zunow!" But before I chuck the relevant catalogues into the trash (as I very soon shall), I'll try to cater to related questions posted here.
