comment:I have tested this, and the lenses listed, using the Koren, 2003, (5mm) test charts to determine the resolution based on the MTF-50 criterion. Two of the sine-wave, test, strips; one horizontal near the center of the frame, and the other, diagonal, very close to the corner of the frame. The tests were made with a KM5D, hand held, image stabilization “on”, ISO 100, in bright sunlight so that the shutter speed was quick enough to satisfy the reciprocal of the focal length criterion. Results: (focal length/f-stop/lines per inch on an 8” x 12” print at center/ditto-at corner). (300/8/128/63), (300/5.6/97/38), (75/8/119/65), (75/4.5/108/61). My understanding of photo resolution quality is: >150 lpi=excellent, >110 lpi=very good, >80 lpi=good. I have some very nice 8” x 12” prints from this lens at 300 mm as well as macros of flowers. While not up to the Beer Can, or the Sigma, it produces very good results at f/8. I wonder if this lens, the 75-300 (New), and the 75-300II are all the same optically. The physical specs suggest they are. More details on this and other lenses can be found at: http://www.geocities.com/royanddee/lens_test_results_mtf50.htm
