Originally posted by hinman I test the my 2nd copy of Pentax F-1.7x AF TC but this time on a Pentax A 50 f/1.7, I essentially get a Pentax FA 85mm f/2.8 with partial AF. I tested it at night with wide open apertures in f/2.8. The combo with A 50 f/1.7 is very sharp and bokeh is quite good even after the TC that extends it to 85mm with 1.5 stop loss. But the magical TC turns my A 50 f/1.7 into AF at night. All test shots are done in f/2.8 in ISO 400 with K10D in JPG.
Some really good shots, hinman, they turn me hungry!
