>>4362000Based. I am excited to see your pictures. Macro is a practice in patience, but so fun and can be very rewarding. :) If you don't have ttl metering on your camera you'll need to bump the exposure up a bit.
I found a 35mm zeiss luminar lens attached to a tophat sinar board that I scooped up from ebay. I have no idea how it will work, but I should be able to get stupid levels of magnification from it.
