I'm getting started with wedding photography, and was looking for a fast telephoto zoom to compliment my Tamron 17-50 f/2.8 (on a Canon 500D/T1i).
After extensive online research, the 70-200 f/2.8 came out as the clear winner.

Why do we talk about focal-length when frame sizes are different?
I keep seeing people talking about focal-length of lenses without saying how large the frame is. Is there a more sensible way to talk about how much a lens “zooms”?
(I have seen so many adverts etc that just have the focal-length(s) of a camera so…

Does lens speed still increase meaningfully when the physical aperture is larger than the sensor size?
This question came to me this morning, thinking about 50mm lenses. I have the Pentax 50mm f/1.7 (manual) and it's a very nice lens, but would be considered (relatively) slow on 35mm film, and many recommendations would be for a 50mm f/1.4.

Is a macro lens suitable for distant subjects - wildlife, sports, portraiture?
Some macro lenses have a really nice focal length that would make them a nice prime-telephoto lens, but are there any downsides of using a macro lens when shooting distant subjects (besides the lack of zooming)?

Does every frame of video (or live view) on a DSLR count as a shutter actuation?
From time to time I see questions about shutter actuations on this site and this got me thinking — does every frame of video count as an actuation?
Does this means a 10 minute video is "worth" 18000 actuations (10minutes*30fps)? And then what about…
