I've often felt that the pictures I've taken on my Canon 7D are not always as sharp as they could be. Its been noticeable in a number of situations and I've put it down to operator error or wrong settings.
Its been particlulary annoying when going out with others to do wildlife pictures. Ok perhaps I can't expect to compete with a Canon 5DS Mk II and a 300mm f2.8 L lens, with my 7D and Sigma 120 - 400mm lens but I'm sure I should be able to get sharp(er) shots more of the time. The Sigma lens is well regarded and I do get the odd sharp shot but not as often as I should. In some images I can see that the Auto Focus (AF) point is spot on an animals eye for example but the eye is "soft".
One of the things that was bugging me was that certain shots with the subject close to the ground, showed sharp focus in the foreground going soft on the main subject. After a bit of judicious Googling, I stumbled on a page from Northlight Images which exactly described my problem and how to fix it.
I'll not replicate here the work on the Northlight website, suffice to say that when I tested my camera/lens combination, the sharp point was indeed in front of the AF point. Using the 7D's "Micro Adjustment" feature I was able to correct this in the "test" scenario. I've had a quick go "in the field" and things did seem much much better though low light levels and high ISO's meant things were a little soft all the way through.
Hopefully I'll get out in good light in the next couple of days and see a great improvement.
Watch this space!
