I currently own a Canon 28-135mm f/4.5-5.6 IS lens - this is a good lens and I'm reasonably happy with it. It has good points (IS works well) and it has bad points (quite slow aperture, and I would prefer better image quality - in colours and contrast).
The lens represents the longest zoom in my camera bag - 135mm. I am thinking of buying a Canon L 70-200mm f/2.8 IS to get that little bit more range that I need. This seems like a good move as it means I retain IS, and I will also get the fast aperture and higher quality glass.
Can someone help me out and perhaps show a photo taken at 135mm and the same scene taken at 200mm? I don't mind if it's 'knocked' up in photoshop to show the field of view, but real photos would be ideal. Reason being that I am considering other lens that stretch to 300mm. However, as I rarely need much more than 135mm, I would probably be just fine with 200mm.
If I do go for a 70-200, I would probably look to sell the 28-135mm and replace with a higher quality zoom, (24-70?) to stop the overlap.
There's one thing I don't like especially about the 70-200 (and yet I like this at the same time) - it's not subtle. I hope 200mm is long enough to get good candids whilst waving about a 3lb huge lump of white lens in someones direction!
p.s. I would get a 1.4 teleconvertor at the same time as the 70-200mm.
