I am considering adding a tele to my stable, and own both a Hasselblad 2000FC/M and a Contax 645 AF, which I use with film and film+digital respectively.
The two obvious choices are the Contax 210mm f/4 and Hasselblad F/FE 250mm f/4. The AF of the Contax is not important, and neither is the stop-down aperture of the F/FE, when used on the Contax. I work slowly and manually by preference.
I am wondering if there are any advantages with respect to metering of the Contax?
Secondly, the Contax appears to be slightly sharper, according to MTF and other charts available from Zeiss.
The advantage of the F/FE is of course that I can use it on my Hassie, as well as the 20% extra reach. I don't use it as often as the Contax, but I do like it and will keep it until I upgrade to a 203FE or 205FCC one fine day.
Does anyone have experiences to share about these two lenses? How do they do with an extension tube for portrait duty? For wildlife? For landscape?
What are the going prices for each of these?
Thanks in advance for all tips.
