I said I would report back on some tests I was doing with the Pentax 200mm F2.5 and the Tokina ATX macro convertor ( the one that comes with the 90F2.5 macro.) The tests are in and the results are excellent. Not extensive tests by any stretch of the imagination but enough to convince me that I don't need to invest in an expensive 200 mm macro. All I have to do is use what I already have to its fullest extent. The photographs — tight shots of an iris — were incredibly sharp. The speed of the lens allowed me to soften the background -Great bokeh. I will continue to experiment with various lenses using the macro adapter and report back when I have results.
