135mm f/2 + 1.4 II vs 200mm f/2.8

[criza]

my experences with TCs are that they work pretty well when the subject is closer to the camera like the shot Dave took above, but the main reason I use Tcs is that when I can't get close enough to the subject.usually the results are not quite good when the subject is farther, softer and CA are the main prblem. I prefer to just move my legs to get closer instead of use TCs or zoom lens. but my 1.4TC II with 300mm2.8 and 500mm 4.0 are pretty good.

This is a good point. The 200mm + TC 1.4 combo is very sharp for close subjects, if the subject is farther (maybe 50 meters and plus) the IQ degrades and it's on the edge to be acceptable (for me). I will continue to use the combo and maybe post some pictures in the future. Unfortunately I just rented the 135mm I mentioned in my first post, so no more tests so far :-|
