A 50mm lens on a croppy is the equivalent of an 80mm lens. Can't see how that would be a good walkabout lens for anyone? :shrug:
It's the lens that is attached to my camera that I use every time I'm out, therefore it's my walkabout lens. I used the 50mm 1.8 before hand. I suppose it depends on the type of photos you take really, but that's the one that suits what I like.
I do have other lenses, but this suits me more. While I like my 12-24 sigma, I'd hardly call it a walk around lens, or use it as such. I don't own the 24-70 as currently it's outside of my price range until later this year, and as a II version is rumoured to be coming out, I think I'll wait.
When I move up to the new 5DmkIII when it's out (if it's any good!) I may buy a package including the camera, grip and that lens. Although I'd be tempted to buy the 85mm lens instead. I really love that focal length.
For what it's worth, I'm surprised that people are seemingly almost offended that I use a 50mm lens as a walkabout. Doesn't it occur to people that as a photographer (or in my case, a bloke that has a camera and a series of lenses
) can use whatever they want as a walkabout lens? I realise most are looking at it from the point of view that you've got more versatility with something like a 24-70, but not everyone wants to use that range. :shrug:
I should stress though, that in the area where I live, the lenses I own suit the area. I rarely take photos in a confined area that needs 24mm and the only shot I've take recently at 12mm was of a church and I could have done with being on FF for that too
Also pretty much everywhere around here has a lot of open space, so I'd more than likely be using a 24-70 at 50-70 anyway.
