So what you're saying is you have some expensive lenses then? what are they?
as for the pics, none of them were taken with a 30D but I will tell you what I think:
can't see 1st one
2nd one is a sunset through some trees
3rd one is of some lillies in a pond
4th one is of some Wildebeest looking at you
5th one is of a Lion looking pissed because someone is shining a fuck off spotlight at him
6th one is of a waterfall
