Selection Dilemma: Pentax SMC FA 645 200mm f4 OR MC Carl Zeiss Jena Sonnar 180mm f2.8

I have no experience with the 645 series lenses but I have a Sonnar 180mm f2.8 which (as the reviews indicate) is quite sharp but probably no sharper than the FA 200mm f4. But the Sonnar at 1350g is twice the weight of the Pentax. This could be an issue if it is hand held. On the other hand, on my measurements, the Sonnar is actually about f2.5 at its widest.
