Finding high performance around 200mm has always been a bitch. My manual-focus primes off the shelf are either the huge CZ 200/2 C/Y or the dainty but middling Yashica 200/2 MLC. Modern zooms are amazing these days but fully automated and not small (I own the 70-200G and E). In the absence of tripping over the C/V 180, my best compromise with manual-focus and apo correction is the Canon nFD 80-200/4.
