No offense, but as someone who sold 135/2 DC for 200/2 AiS I can guarantee the 200/2 AiS is superior in every way. Without AF the 135/2 wouldn't even be in the same league. But I agree on the weight part, that can be a disadvantage. I for one love how heavy the 200/2 AiS is
Of course they're both amazing and if someone switches let's say from 50/1.4, they'll be blown away by either of them.
The 200/2 VR II blows away the 135/2 DC. Also blows away the Zeiss 135/2 APO Sonnar to a lesser degree (but mostly because of the AF).
Weight? If you really love photography and you have a 200/2, you will work out and get stronger to handle it. Else you really don't love photography enough to own a 200/2, in my opinion.
