I was trying out my lens at 70mm earlier on and here're 2 100% crops of the same image, one taken in Manual focus & the other in Autofocus. Much as my MF skills are subpar, I've been trying and somehow the MF results are always alot less sharp than the AF shots.
Can someone tell me what I'm doing wrong? I generally turn the focus ring till the image looks sharp on the viewfinder then take the shot, which has often worked pretty well for me in film SLR on my old Nikon. Using the Canon EOS 350D, I cannot seem to master the MF mode at all without looking like the focus was just the wee bit off.
Can someone advise me please?
Thanks in advance
Autofocus at 70mm
Manual focus at 70mm
Note how the MF mode seems to produce slightly blurrer results even at identical settings for both the aperture, ISO and shutter speed?
In case it helps, the lens I was using was the Sigma 17-70mm, at 70mm, f/4.5, 1/5 second mounted on a tripod and ISO 100. Cam was a Canon EOS 350D
Would appreciate any pointers from the pros on how to improve my manual focus technique. Presently, it's turning the focus ring till the image is sharp in the viewfinder, then turn a little more then turn back to where the whole image was sharp again, especially the area where I wish to focus on.
Many thanks in advance.
