I've got a KX and so far my most used lens is an A 35-70 F4. I'm quite happy with that. I also have DA 16-45 and screwmount 55/1.8, but 70% or more of shots use the 35-70.
Looking at the reviews: http://www.pentaxforums.com/lensreviews/SMC-Pentax-FA-28-70-F4-Zoom-Lens.html It appears the 28-70 might be even better for me. Lighter, auto-focus, and a wider zoom range. What's not to like? KEH have one, ex+ for $119. It seems worth asking here before taking that plunge. Anyone used this lens on digital? Can anyone compare this at 42-105 equivalent to the old 35-105 that was many people's favorite lens on film? For that matter, has anyone got one to trade? The 16-45 is a fine lens, but I'd happily trade it for the 28-70 and something else. First choice, 100/4 or 3.5 macro, but anything that looks useful in a lightweight kit with KX and 28-70 might be of interest. 50/1,4, 20 or 135 mm lens, 45-125 zoom, ...? Contact me off-list if this is of interest. -- PDML Pentax-Discuss Mail List PDML@pdml.net http://pdml.net/mailman/listinfo/pdml_pdml.net to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions.
