All at sixes fives and sevens - part 2 of 1 2 3 4 5

by Jon Ashton Published 01/12/2012

In use Jon did not detect much difference between acquisition of the target and focus lock-on although he did get the impression that the 5D was better able to stay locked on during flight tracking. Other reports confirm that the focus of the 5D Mk III is superior to the 5D Mk II.

Given that cropping is likely to be essential, the residual noise of the chip becomes important. In this department the 5D Mk III is superior, an expected result with the pixel sites being larger. The opening image of this piece is made without scaling the resolution from the camera. At 300ppi, the native image size is 48.8 x 32.5cm (19x13 inches nominal) which is more than enough to cover a double-page spread in Professional Imagemaker and the image has been placed over to the left and to the bottom - effectively a 2-inch crop to the side.
