I, too, recall the earlier one. I have to be honest, and say that I prefer that one to the new one. I like the colour rendition and sharpness. The Pentax seems more "contrasty" than the Vemar. OTOH, given the fact that there's ice in the latest one, maybe it's not fair to compare in the way I did. OTOH, you asked, so I guess we can throw fair out the window, eh? <g> cheers, frank -- "Sharpness is a bourgeois concept." -Henri Cartier-Bresson
