So I did. I carefully squared up the projector and screen (better than I usually do). I tried each lens with both of the types of slides. My comments about the CF and FF lenses were correct - in the case of both the plastic and cardboard slides, the Supercolorplan FF was the best. The plastic mounted slides were quite close to being sharp accross the slide, the cardboard mount slides less so. The interesting thing is that here was more distortion with the the CF lens on the cardboard slides than there was with the FF. However, there was a much greater difference in the projected image quality between the colorplan and the supercolorplan than I had remembered. The supercolorplan was noticeably sharper, even in the center of the slide. Also I noticed that when I changed from the colorplan to the supercolorplan that the slide seemed much brighter, practically like 1/2 a stop. I tried this back and forth several times and saw it each time. It seemed to make the slide sparkle - I can't seem to find the word I want, oh well! Conclusion, my CF colorplan goes back up on the shelf (where it was anyway) and the Supercolorplan stays on the projector. Hope this helps, Dick
