I had big plans for today, but work caught up with me and I spent most of the day indoors. But I am so eager to find out if the AF system of this lens works, so I have had to run around a bit to test that. I have done low light (1/50s, f1.4, ISO8000) shots and some outdoor shots.
I have only done f1.4 shots in Av, with single point focus, and AF set to One Shot. ISO has been set to 100 as much as possible. In some cases I hit the roof at 1/8000s, so the f-stop increased a bit. But the most interesting are of course the low light indoor shots.
And so far I am VERY pleased.
I am very close to a 100% keeper rate (if you ignore the fact that 99% of the images are rubbish). The only one I had problems with was a fairly slim glass candlestick, where it consistently focused on the plane behind it. Color, bokeh, CA and all the rest is not something I have spent much time on yet, but I have seen nothing I can´t live with. Quite the contrary.
I could have posted pages of images to confirm this, but considering the rubbish motives, I´ll limit my self to one of the Local Lion. The reason for shooting images of the cat (yes, I know all the jokes of door nobs, cats and cutlery...) the detail you can find in his fur has lots of information and it is very easy to see if you nailed it or not. The focus point is on his left eye (to your right).
