I took my 24-70mm f2.8 lens and a 35mm f1.8 prime lens and did a side by side comparison. I set the camera up on a tripod and set a number of brightly colored objects with sharp designs up in my back yard. I set the 24-70 lens at 35mm and took a whole battery of pics in M, A and S modes using various shutter and aperture settings. I documented each picture setting with one lens, swapped out the lens and took all the pictures again. I set the camera in RAW mode and was shooting at ISO 100. In the end, most of the pictures with either lens looked really good. Half were nice and sharp and some were only so-so. I think that was probably the lighting as it was cloudy out. Some times the sun would break through the clouds and light everything up nice and bright. One thing I am a little perplexed about is something I see in the exif info for some of the pictures I shot with the 24-70mm lens. Out of the 26 test pics I took, 5 of them showed a Focus Mode of Manual. The rest showed Auto. Those pictures still looked pretty good, but I cant figure out why the focus mode is different. I wasnt moving the camera between shots. Most of the time I would change the setting on the camera, reach up and snap the picture, change the setting, take the picture. I am 99.99% sure I never touched the focus switch on the lens. Is it possible this is expected behavior when shooting at a fixed object from a tripod where there is no movement between camera or subject? </p></blockquote><p></p>
