Related to but not entirely on track with the original subject ... In my experience, the Pentax-A Rear Converter 2x-S does very well with the A50 Macro, A200, FA77 and FA135 lenses. It works particularly well with the A50 Macro to provide both a longer macro focal length and 1:1 imaging at a greater working distance. I've kept it specifically for this purpose. I found it exaggerated blooming (red fringing) with the DA70 and DA50-200 to an excessive degree, have not tried it with the DA*50-135 as yet.
