Hi
I've just started in the world of photography and bought an EOS 450D with 18-55mm lens....
I am now looking forwards to my next lens
thinking: expensive hobby) and just want a bit of advice really....
What I want to picture is, well anything really.... I am an overenthusiastic holiday snapper by nature, so I like doing landscapes and tourist sights and that kinda stuff, but I'd also like to be able to take quality portrait pictures and the like....
my current thoughts are:
-existing lens doesnt give me the zoom capability I'd like - so I need a zoom lens
- the max aperture of the existing lens is 3.5 and doesnt do enough to throw background out of focus for portraits...
SO I am looking to get one new lens initially, probably a zoom one, and have looked at a few ranging from 18-200, 28-200, 55-250 and 75-300....
my thought being if i bought an 18-200 then it replaces my current lens, which is good in terms of not having to change lenses over, but am i paying fo the same thing twice for example?, so should i go for a 55-250 and pick up from where my existing lens left off - giving me a good range from wide to zoom lenses.....
I am also unsure about the Canon vs 3rd party lenses, though I was given strong advice by my friend to stick to canon....
any thoughts, opinions or guides appreciated at this stage

We're by and large a friendly bunch and TPs claim that it's the friendliest 'tography forum there is is largely accurate. Been hiccups of late but they seem to have been ironed out 

- given the range of uses I want to put it to I have concluded myself that the 55-250 with its IS will be more flexible to me, preventing the reliance on using a tripod for zoom shots!?? - i've also read that the push/pull on the 70-210mm is a bit of a pain when pointing up or down?
