Some more IR photos with istD

Further to the test before, here's are more try-out of IR photos with istD. With the better IR sensitive, I am able to shot at a lower ISO level (ISO800 in this test), and I am satisfy with the results.

I am in the process to get the correct focus at close-up photos with my Vivitar Series 1 105mm f.2,5 macro lens. Hope I can get some interesting macro / close-up IR photos later.
