Numbers are complete guesses but I'm trying to be realistic... Lens name: SMC Pentax-FA* 400mm f/4.0 ED IF Length: 300mm (not including hood) Diameter: 120mm (not including hood) Weight: 2500g Filter Thread: 49mm (rear) Other: Focus limit switch, AF/MF clutch, bayonet-mounting hood, minimum focus distance 2 metres, f/4.0~f/45, rotating tripod collar. Basically a faster FA*400mm f/5.6 with a focus limiter added. Lens name: SMC Pentax-67 65mm f/2.8 Length: 75mm Diameter: 90mm Weight: 550g Filter Thread: 77mm Other: Built-in tulip hood, f/2.8~f/22. I'm glad you didn't specify 35mm format only :) This focal length would fit nicely in a kit with the 90mm f/2.8 (the 75mm f/2.8 is a little close for my liking). Lens name: SMC Pentax-M 1:1.4 35mm Length: 62mm Diameter: 65mm Weight: 420g Filter Thread: 58mm Other: M-series My third choice is this prototype. Runner-up for third is a 35mm f/4 rectilinear for 6x7. Now that would be expensive. --- Cheers, - Dave http://www.digistar.com/~dmann/
