Very impressive, Mark! I like the DOF. Did you do anything special for it? You didn't do focal-HDR, did you?
I tried to play with the same combination of lenses a few times, and my results were acceptable but not as good. My biggest struggle was the DOF, even with the aperture closed down. (I posted those attempts to PDML a while ago: http://science.komkon.org/~igor/PHOTOS/Raspberries/IMGP9527.jpg http://science.komkon.org/~igor/PHOTOS/Raspberries/IMGP9503.jpg ) The DOF became incredibly shallow (and the sharpness went down) when I stacked 2.0x with the 1.7x (and still with the same DFA-100/2.8 macro): http://science.komkon.org/~igor/PHOTOS/Raspberries/100-2_0x-1_7x/ Igor On Tue, Jun 14, 2011 at 7:52 AM, Mark Cassino <markcassino at ymail.com> wrote: > This weekend I tested out the D-FA 100mm macro combined with a Kiron > MC-7 2x > teleconverter and also combined with a Pentax 1.7x AF adapter as > alternatives to > a 200mm macro lens.
