Re: Avoiding EF-S Lenses... Smart or Dumb?

Just go out and buy a 5D, you know you want to.

I think that line of thinking is a real issue when considering EF-S lenses. A 10-22mm EF-S lens would suit my current yearning quite nicely, but they're expensive - £500 here in the UK. Since I have a 17mm lens, I could get a very similar wide angle by not buying the EF-S lens, but by replacing my 20D with a 5D.

A 5D is £1,750, so there's still a big difference in the cost of the new camera as opposed to buying a new lens. If I needed that wide angle right now the EF-S lens would be the cost effiective way to get it. The thing is, the 5D has come down from about £2,500 when launched, about a year ago, while the EF-S 10-22mm has gone from about £600 to £500 in 2 full years. Given the way camera prices come down very quickly, and lens prices tend to stay static, in another year or so trading in the 20D for the FF option of the day will make an awful lot of sense.

So, since I don't need that ultra wide angle right now, I'm sitting tight until I do. At that point I decide whether a FF camera of an EF-S lens is the answer. I very much doubt if the EF-S lens will make much sense. I'll almost certainly do exactly as you say - go get a 5D.
