    Who here has the Canon D20?

    Because I'm having real problems focusing ours. The Nikon D100 is too good, but the D20 is crap and I can't see why.

    Got a Canon pro lens on the D20 and the Nikon has a Tokina which is a cheaper lens.

      Paul,
      Describe the lighting conditions when you're having these focusing problems. As you already know, the cameras will sometimes have difficulty in low-contrast scenarios, and low light can contribute to this.

      The 20D does not have any inherently flawed focus problems that I'm aware of. I've used it professionally and my opinion is that the camera rocks. I've not had any complaints. I just ordered myself an XT which has the same focusing system, because I've been equally impressed with the performance of these cameras.

          I do. But I'm pretty novice (20D's are known to have a higher number of lemons whose sensor/chip whatever doesn't focus properly)

              I haven't heard of that issue. And I spend probably too much time in the photography forums.

                      maybe the viewfinder?

                          I'm shooting exactly the same thing with the D20 and the D100 and getting different results, very different.

                          Going to lunch and will work on it when I get back. But there is something wrong.

                              Yeah, that's a really good suggestion. Paul, are you sure it's the actual photos that are blurry and not just the viewfinder focus?

                                  I got the 20D and love it! No problems at all with it!

                                      what's the "Pro Lens" I highly doubt it's the 20d, I bet it's the actual lens itself.

                                              No there is something wrong with the camera, here are two pics, some shot, lighting and position. Both cropped to actual size and compressed 88%





                                              The Nikon is sharper.

                                                      are the white balance settings identical ? was it taken with a tripod or just hand held ?

                                                          Two different makes of camera so balancing the whites balance would be tough. Hand held but firing with strobes so not a problem.

                                                              Paul, some copies of these cameras like the earlier 10D can have back & front focusing issues, and some lens can as well. Here is a link to a test for front & back focusing testing. I've had to deal with sub par copies and am happy I exchanged them.

You get what you pay for and here is just more proof that I will continue to only use Nikon. BTW, why the hell would you use anything but Nikon glass? Seems unthinkable for someone to use a knockoff like Tokina when spending that kinda of money on a Nikon body.

                                                                          Apparently, its cuased from the lens and the body's connections, having grease or dirt on them.... remedy.... a rubber eraser to clean off the connections. Works most of them time.

                                                                          and I had to send the rebel in once becuase the shutter locked up.

                                                                          We use them alot, so maybe its just normal wear and tear, but weve had alot of problems with them.

                                                                                      is focal length magnifier the same for both bodies, if it is not but cameras are in same position on tripod this will change DOF even if f/stop is the same.

                                                                                      are both lenses screwed in to the bayonet stops?

                                                                                      many variables could cause this.

Here is a link to a test for front & back focusing testing. I've had to deal with sub par copies and am happy I exchanged them.

                                                                                          I have the 20D and my pics focus much better. I have an EF S series lens

                                                                                          Shooting_Maniac1 The Canon D20 is a lot more money than the Nikon D100, so that's not the issue. On the nikon we tested the Nikon lens and the Tokina, identical results. I wonder where Tokina and Nikon get there glass from?

You get what you pay for and here is just more proof that I will continue to only use Nikon. BTW, why the hell would you use anything but Nikon glass? Seems unthinkable for someone to use a knockoff like Tokina when spending that kinda of money on a Nikon body.

Manual always gave us a better picture, the Jpeg files seem to soft, a D60 will do on average a better job for 1/3 the money. We have switched over to Nikon, d100,d1x,d2x, after the problems we had with this camera, "" note we kept 1ds great camera "

                                                                                                                              Buy some pro cam like D1 - its giving a great results and you can see the difference just looking at pic.

If you're shooting in JPEG then try fiddling with the sharpness settings on the camera. I believe the Canon has a more aggressive moire/IR filter which does lose some sharpness.

                                                                                                                                      It may also help if you actually tell us which Canon lens you're using... you seem to keep avoiding the question.

                                                                                                                                      Finally, taking a test shot of a small object isn't really indicative of real world shots, unless you want to fill the screen with a model's nose.

                                                                                                                                              Seems we're not the only ones.

                                                                                                                                                      Apparently, its cuased from the lens and the body's connections, having grease or dirt on them.... remedy.... a rubber eraser to clean off the connections. Works most of them time.

                                                                                                                                                      and I had to send the rebel in once becuase the shutter locked up.
