Backfocus...a real pain!

Back focus is when the focus point or the focal plane is behind of the focus point where you originally intended. I first noticed this issue with the Canon EF 50mm f/1.4, especially with the aperture wide open. Although taking close-up shots, it is not much of a problem but as the distance between the subject and the camera increases, the back focus problem worsens. Mucking around with the autofocus/microadjustment setting of my camera improves the situation slightly but the problem is never fully resolved. Hence, AF with the 50mm is unfortunately a hit or miss affair most of the time. With the Canon EF 70-200mm, it consistantly front-focus for some reason, luckily by adjusting the autofocus/microadjustment setting to +5, it fixed the issue all together...or as far as I can see anyway.

These shots were taken on Sunday in Perth during a lazy afternoon stroll. Despite the unpredictable weather and sporadic downpour, there were still plenty of shoppers around for the end of yet another financial year sale.
