do i really have to pay lifepixel $95 dollars to have them send me a sensor sized filter to replace the IR cut one already on the camera? or is there somewhere else to buy them? i suppose $50 sounds more fair, but $30 for a 52mm one sounds pretty nice if i can cut it to size... has anybody figured any methods besides paying all the money to block visible light for converting a d70... also... if i DO cut it, what would be the best way? and does anybody know the exact dimensions (of the filter (i'm assuming the sensor is a tiny bit smaller)) -drew i have a d70 that cost me almost nothing, and besides a very dirty viewfinder, seems to be working great. i'm not ever against tearing something apart as a little project. so IR here i come!
