There are some complaints about the occasional 24/2.8 not being sharp, but it seems to be an infrequent but genuine problem. Looks like QC problems at Canon with this one. | The 1.8/USM is generally not so good, trusting the MTF figures at | photodo.com. Wide open and at 2.8 the figures are really bad. | At f8 and f4, even the "consumer" zoom 28-135 USM does better. | So not really what you'd expect from a fixed lens of that price. Don't rely much on photodo MTF charts. They only test ONE single lens, and that at infinity. If they'd tested 10-20 samples then the numbers would make sense. | It seems to be really difficult finding a good 28/24mm for EOS. | I'm wondering about the newer 3rd party lenses. | Does anybody have realiable figures for them? I've been using a Canon 24/2.8 and I must say the quality is excellent. I've made 12x16" and 16x20" B&W prints and I'm truly impressed with the corner to corner sharpness and contrast. The enlarging lens and printing paper matters a lot. For these tests, I use a Rodenstock rodagon 50/2.8 and print on Agfa classic glossy. * **** ******* *********************************************************** * For list instructions, including unsubscribe, see: * http://www.a1.nl/phomepag/markerink/eos_list.htm ***********************************************************
