Roland Vink I use my 200 micro and No. 3T and 4T closeup lenses quite extensively . I have noticed very little image dropoff in quality . I have not tested edge sharpness though , most closeup lenses loose sharpness here compared to extention tubes . Most of my higher magnification shots with this combination has been of small flowers and insects and edge sharpness is less important than other subjects Peter Smith Peter Smith Photography Thunder Bay , Canada
