Cost of the modification is $190 plus $20 return shipping, UPS ground insured. Orders accepted within continental United States only. I can provide a Baader DSLR UV/IR replacement filter for an additional $90.
Cameras are fully tested before and after modification and include flat field and focus test images along with a pre- and post-mod checklist that is provided to camera owner.
On occasion I also sell new modified Canon 450D (XSi) and 1000D (XS) DSLR cameras with the Baader DSLR UV/IR replacement filter. Check website for details and availability.
