Thank you all for the comments.

For me, the good news is that the DA15 is also a good performer at IR shots. Most of my lenses would need an AF adjustment when used in IR photography, except FA31 and DA15.

Interesting. Which don't work out well. is AF the only issue? Is there different IQ performance? This is on a converted camera? How is manual focusing?

It is an IR converted camera, it would not be possible to get such short shutter times otherwise.

These shots have been taken with AF.

The AF is not the only issue in regards of IQ in IR-photography. The lens coating is calculated to avoid lens flare in visible light, in IR however, lens flare can easily occur, even with lenses which would hardly show flare in normal light.

They're simply magical. I'm really drawn to the first one. So much to look at!

Thank you for the comments.

cupic: the IR-filter on the sensor is equivalent to the Hoya R72 (so 720nm filter)
