Great shots with good detail. Do you prefer the APO against using a lens. I have recently tried the XT-1 with a 27mm f 2.8 lens & the results have been quite good up to 15-20M distance. (The combined f No is 8.4 when using the 25X magnification.) I prefer this lens because you get no vignetting & the lens movement for focusing is very small. I do have problems with getting the right exposure depending on the amount of contrast. Interesting camera & scope combination.
