Yes! Thank you! Where both are standing at the same spot, and the 30D and 5D take the same image, the 1.6x factor make you (effectively) 60% closer. In order to achieve the same framing with the 5D, you need to crop 1/2 of your 12.7MP to get a 23 x 15mm frame. The result is that you are reduced to 6.4 MP using a 5D where as the 30D has 8.2 MP and the XTi 10.2 MP. So there are more pixels when using those cameras, that would cover the bird. And I will leave it alone at this point. Thank you for your help. Apologies to the group for not being as clear as it was here.
BTW, anyone using the 135mm F2.8 soft focus lens these days with digital? Do you find you need to go to Soft position #2 to get a soft image with the 30D because of the greater DOF? Just wondering.

I haven't really followed this closely so what I write might be wrong. In any case, it seems to me you talk about different things. Austin is assuming you take two pictures. One is taken with a camera that has a small sensor (1.6x) and one with a camera that has a FF sensor. Both images show exactly the same content using the FULL(!) sensor area. In other words, if you take a picture of a face then on the first camera the face will fill the full APS frame and on the second camera the full FF. In that case whichever camera has more pixels has a higher pixel density. It seems to me (not sure), Peter is saying you take a picture with the two different cameras from the same position and with the same lens (setting). Now assume the camera with the 1.6 factor shows again the full face. Now the camera with the FF shows the full face and some more. In the next step you take out the part from the FF that is shown in the 1.6 frame. If now you compare the pixel density then the 1.6 camera has a higher density although it has fewer pixels. ____________________________________________________________________________________ Fussy?
