I've had my 18-55 since I bought my 20D ages ago, but I've always wanted something a bit better.
the two I'm looking at are the canon 18-55 IS and the Sigma 18-55 F2.8-4.5 DC OS HSM.
I've heard the Sigma is better, but quality varies quite a bit. the newer IS version of the same lens i have now is supposed to be much better.
Yes If I had the money I would go for the Tamron 17-50 or even better the Canon 15-85, but money is tight and these are the choices I have left.
I mostly shoot land and seascapes, so which would be the better choice?
