Andy, The basic choices are going to be Pentax 28-70/2.8 or 28-70/4, Tokina 28-70/2.6-2.8 Pro II or Sigma (various choices). The general talk that has been on the list is that the Pentax 2.8 is optically great, but physically poorly built and very expensive. The Pentax 4.0 lens is optically quite good, physically mediocre and quite inexpensive. The Tokina is optically quite good, physically the best built and reasonable price. It's biggest weakness is flare control compared to the Pentax offerings. I haven't heard about any Sigma's worth considering in that focal range.
The usual two come down to the Tokina 28-70/2.6-2.8 Pro II or the Pentax 28-70/4.0. Some difference in price, speed and build quality. The Pentax wins on price and flare control, the Tokina wins on optical and build quality. In my quest to purchase the 67 glass, I have been selling all lenses that I could stand to part with. My Tokina 28-70 Pro II is still on the shelf here. I haven't decided whether to let it go or not. It can be so darn useful - especially at 2.8 speed. If there is any interest, let me know. I might consider selling it - mint condition. Bruce Dayton Thursday, April 11, 2002, 3:51:30 PM, you wrote: AV> Dear list, AV> I am looking for a zoom len 28-70 for my pz1-p. Any AV> recommendation??
