The Sigma EX DG HSM (non-IF, penultimate version in PKAF mount) is the best AF full frame zoom I own, without doubts.
I have no complaints. I prefer to shoot primes, and if possible I shoot with manual focus lenses, but when the conditions call for AF, I know I can rely on this lens.
If there are fast moving subjects, especially at night, the keepers rate is already hampered by the objectionable performance of the AFC. Using MF lenses would seriously decrease the number of correctly focused images.
My K-1 does better than previous models, as far as tracking is concerned, but it still lags behind other AF cameras that have many more AF sensors and a much better AI (that makes the camera choose the subject in the foreground instead of those in the background!).
I went out to shoot the traditional parade on the last day of Loi Krathong festival, in Chiang Mai, Thailand.
I brought many objectives, AF and MF, but in the end I used only the Sigma.
Depending on the subject, I used either AFS or AFC, and I had no problems with the more static subjects.
With moving groups of people, and with plenty of spectators getting in the picture all the time, I had a number of badly focused shots. Even more so with fast moving subjects like sword dancers or other very dynamic subjects.
I should abandon my film era attitude and start to spray and pray, taking far more shots than I usually do.
Coming from large format photography, it's a totally new mindset. I should try to adapt... :)
Here are a few rather static pics, quickly post processed without selective corrections.
I used the lens correction profile available for Nikon full frame cameras with identical/similar Sony sensors. It seems to work fine.
The color cast on the subjects is due to very warm street lights. Unfortunately the background lights are way colder.
If I adjust for one, the other would be totally off.
I decided that it was preferable to leave the skin tones very warm. In hinsight I should have tried to compensate more.
