Definitely not. Super-wide to telephoto isn't a good idea, especially on the 50D. There's little point in buying a camera like a 50D if you're going to put very mediocre glass on it. There was a lot of moaning about the 50D being soft, when in actual fact for the most part it was simply highlighting any tiny faults a lens had.
I bought an 18-55 IS
for my 50D, but returned it because it was just too soft. On my mate's 1000D however it wasn't too bad. Goes to show.....
When you start using cameras with a high MP
count on a FOVCF sensor it's much like using FF
pro models such as the 5D II
; i.e. they will immediately show up a bad/mediocre lens.
You wouldn't believe the amount of hassle I've had with low end (and even some medium range) lenses. It's just not worth it. I wholeheartedly recommend the 28-105 f/3.5-4.5 USM II
- discontinued now but if you can get hold of one I reckon you won't be disappointed. That is of course if you can live without the extra 10mm at the wide end the others offer.
Honestly Alfie, don't beat about the bush with your gear - go for the best stuff you can afford because if you're serious you're only going to plump for it in the long run anyway. If your budget becomes restricted, remember it's always better to go for a cheaper body and good glass.
