Hi
>2 of my friends and I own EOS 20D's (I also used to own a 10D) and none >of us are particularly happy with the sharpness of the images we are >getting. using jpg? > >We've adjusted the in-camera sharpness control (with some positive >results) and sharpened the images in Photoshop (with some more positive >results). However, the images still don't look really sharp. yep ... using jpg perhaps it might that the incamera JPG generation stuff is making sharpening effects that are not simmilar to those I get using Photoshop. I first observed this some time ago when changing from a Coolpix 950 to a 9950, where it at first seemed that the images were not as 'sharp' >experienced baseline for expectations. I've shot with both EOS film and >FD Canon's, one friend shot with a Canon A-1 for many years. He also >has some amazingly sharp sample prints from a Nikon CoolPix 5700. In >fact, he feels that he's never got as sharp a photo from the 20D as he >got from his 5700. it could be that he's just getting into more detail. I know that in my own learning curve that I've felt that about stuff, and gone back to compare scans taken from RDP-III 4x5 sheets and understood that there were sharpening artifacts at work in perception but my CPix 5000 might look on PS to be sharper than 1800dpi scans of RDP-111 with a Fujinon 90 f8 but the print at 300 dpi is just not as sharp as that from the CPix yet seems to be ok on the monitor. >I've heard, here, that Canon can "calibrate" the camera to produce >sharper results and I have questions... > > Does Canon need both camera body and lenses (I've got more than a >dozen, half of them are not Canon brand)? > yes, I've since sold my 20D and I'm waiting for my 10D to arrive. I tried testing the focus points with the various tests on the net, and found that it compounds things by focusing before the target. I also had some other issues with it, but lets not go into that here. > How long does it take? > > What does it cost for out-of-warranty cameras? > no > Does it actually work (does anyone have a before and after test shot)= >? > > How many of you have had it done? > > WHY CAN'T CANON GET THIS RIGHT IN THE MANUFACTURING PROCESS??? > well I guess that it's a dimishing returns issue. They could put more into the QA, but then that would knock off the competitive edge from the cameras price. I am confident that so many are problem free, that the issues experienced by some of us will not effect sales. besides, there were so many changes in shutter system from the 10D that there was bound to be problems. >Mr. Bill > >P.S. Does anyone have an opinion of the relative sharpness of the >images produced by the EOS 5D compared to the 20D? > > an image taken with a lens of mine sold to a fellow with a 5D showed sharpness of about the same as the 20D only over a greater coverage area. He shot a subject that I can't get to to shoot so I can't compare eggs with eggs try testing your camera for being in focus a sheet of paper inclined with lines on it is a good test, there are many on the web detailing how to do it. if its in focus, it might just be that its a preceptual thing. After all JPG do have perceptual techniques in their design. Lastly look at this page http://home.people.net.au/~cjeastwd/digital/jpgVSraw.html while I am not trying to discuss perceptual issues, you might see from the JPG's that I analise some 'sharpening' things which may change your views on sharpness and perception of sharpness. :-) * **** ******* *********************************************************** * For list instructions, including unsubscribe, see: * http://www.a1.nl/phomepag/markerink/eos_list.htm ***********************************************************
