I discussed the flexibility of a 70-200 zoom versus a 135 prime with an old photographer buddy of mine and he joked .. "You too lazy to take a step?"
Fill the frame with a scene at 200mm, then reset your zoom to 135 and move three feet forward .. and voila you have filled the frame with the same scene. Same thing from 70 to 135mm.
Works different at different distances but at many people shooting distances it's usually only a few feet back or forth.
yeah. the difference from 70 to 135 is almost doubling your distance to your subject. so indoors, if you are shooting at 10 feet at 70mm, you have to go back to 19 feet about to shoot at 135. in addition, the 70-200 is an awesome landscape lens. tell me how you would take a few steps back and forth to recompose for landscape. and your old photographer buddy I am sure is aware on how distance to your subject changes perspective right?
I concurrently owned the 135 and 70-200 2.8 IS (first version) and sold the 135 within 2 weeks. there are 3 main advantages/uses/occasions the 135 may have over the 70-200 2.8 II.
1. Cost
2. Weight, size less obtrusive
3. shooting low light sports/action, where shutter speed is far more useful than IS.
shooting people, esp on the newer higher MP cameras, as long as they are not Moving much, I always find IS worth more than a stop of light on the long end. on a crop high density sensor you need at least 1/250-1/300 ss for consistently sharp images, and on a full frame around 1/150-1/250. where as somewhere between 1/60th to 1/100 second is fast enough for portrait of stationary people to be consistently sharp, which the IS would allow you to do even at 200mm on a crop.
