Oooooooh stop you're getting me all excited now 8) You only have to look at the Pentax A 70-210 f/4 reputation, people are still raving about it now and it's been around 20+ years!!! Constant aperture, reasonable filter size (58-67 would be nice) and easily hand holdable and I think you've got a top seller. John
