SMC Pentax-FA 645 55-110mm F5.6

Hi,

Has anyone here ever used this lens? I am curious of people's impressions.

It sounds like an ideal crop sensor normal to short tele for the 645D (many assumption there, I know). Assuming the D-FA 55mm they display the 645D with is a normal lens (55 is the new 75), this would be like a slightly slower (f/4.5 vs. f/5.6) FA 80-160mm - but much lighter.

So the FA 33-55mm on the 645D (assuming crop sensor) will equate to the FA 45-85mm on the 645/645N/645NII.

This is one of the two 645 FA zoom that I do not have. The focal length looks great for normal to mid-tele. The cost of the weight saving is the f5.6.

I'm tempted by this lens, too, but the f/5.6 has scared me off in the past. It has a great rep but I think its uses are somewhat limited... would be pretty dim in the viewfinder, too.

One thing I have considered is that it would be GREAT to use alongside the 35mm and a 200mm. Perfect for travel, really.

I have this lens. Extremely sharp and contrasty. Lightweight (relatively) and compact, too. After I bought this lens, I sold off my 45-90 and 80-160. It is sharper than both, imo, and the range is perfect. My field outfit is now the 35mm 3.5, 55-110, 120 macro, and 150-300.

I shoot landscapes so the f5.6 speed is not a problem.

So for Pentax Medium Format:
45-85 and 80-160 for full frame and the equivalent 33-55 and 55-110 for "cropped" sensor?
