Originally posted by GeneralBenson Are those all new lenses or are they older 645 glass?
All those are FA 645 lenses that has been release since the 645 went AF in 1997 with the N model. Some of them were released later.
The only released D-FA 645 lens is the 55/2.8. They already have the optical design of this lens as the original A55/2.8 with updates for AF via SDM and digital version of SMC.
In the Photo of 645D lenses each row, left to right:
Top: 33-55 45-85, 55-110, 80-160 all FA's
Middle: 35, 45, 75, 120, 150, 200, 300/5.6 all FA's
Bottom: FA150-300, FA300/4, FA400, A600.
All these lenses were from the 645n/II and along with the 645nII are still available new for purchase in Taiwan, Hong Kong and Japan.
This display probably meant the 75 and 135 LS lenses are no longer in production. No reason why they would not work in the 645D with the aperture stop down shutter triggering mechanism.
The is no question with Pentax's superb optical engineering in the wide and ultra wides that we would expect to see a lens or two in the 20's or maybe even a wider zoom range than the 33-55 very soon for the smaller sensor.
