When I was on a summer vacation in Finland, Åland islands I had a chance to enjoy a cover band from Thailand playing rock and metal tunes. There was a time when they played in that town far more often and two years ago they split up. Recently they reformed with the new line up and started playing live again. During one of the nights I decided to do some photo shooting to improve my skills and to provide the guys with some pictures for promotional use etc. , after all I know them for a long time and I was more then glad to help them out.
The shooting conditions were challenging : dark club, barely any light even on stage, the stage was low and small. First I tried shooting in Av mode, but the camera always chose shutter speeds that were too low. I ended up switching to fully manual operation. Shutter speed was set to 1/100, the aperture on Sigma was set to 1.8. At first I used ISO 25600, because that's what the camera suggested initially. Later on I switched to 12800. At ISO 6400 certain shots ended up being too dark, so I switched back to 12800. Most of the shots were done using contrast detect autofocus in live view. I prefer to use live view, because of the electronic level, for me it is also easier to frame the shots using the display. Besides, in that club the viewfinder was rather useless, as it was too dark.
I really liked the behaviour of the lens in these conditios. F1.8 and ability to change focal length were clear advantages. But at the same time F1.8 made the things far more complicated in a certain way. Depth of field. Considering how close I was to the band, the depth of field was extremely shallow even at 18 mm. When shooting action, it is really hard to constantly keep that in mind and it also seems that the central focusing point is bigger than you might expect it to be. On the other hand it was the only lens in this system appropriate for the job. I can't imagine shooting the show with a fix lens, or with a slower zoom like DA* 16-50. The sharpness of Sigma wide open was a huge advantage : the loss of details due to high ISO was partially compensated by their over-abundance (in a good way).
The shots were processed in DxO 9 using Prime noise reduction engine. 35 photos took an hour and a half to process even taking into account that I am running a 6 core Intel I7. I did some cropping and in certain cases I fiddled with Shadows, Highlights, Exposure and Smart Lighting. High resolution of K-3 was very useful when I did cropping and resizing. The images were resized to 1440 (hight of my monitor).
To sum the experience up, I would say, that K-3 is a very capable camera, for just about any imaginable task (if coupled with a proper lens, like this Sigma).
Here are some shots.
