slimbert, thank you very much... i did indeed miss your offer, it somehow got buried with all the images! :bonk:
nick, absolutely awesome images and wonderful bokeh there.
i am a bit far out for norwich (more king's lynn way) - i'm 99.9% mind made up on it now, it's just a few things seem contradictory:
on the digital picture the crops seem to indicate that at 70mm f2.8 is sharper than 200mm f2.8, yet adam's crops seem to be the opposite of this - so really is this a consistent experience amongst users of the lens?

the mtf charts also seem to indicate that 70mm has lower contrast and sharpness than at 200mm (at f8 and f2.8), but as you can see the digital picture's test chart results seem to show the exact opposite (corner performance seems to improve at 200mm, but the centre is still softer). so are these flawed? the review says several samples of the lens were tested and performed similarly.
in any case, question is, is this difference in contrast at both ends of the focal length truly visible in a (un)processed real world image?
when i look at the mtf chart for the 135 f2 i realise just how spoilt optically i've been... high contrast and sharpness across the frame almost as good wide open than at f8. it's also surprising that primes like the 35 1.4 have quite mediocre mtf scores, yet are capable of truly awesome images.
