Hi everyone im after a bit of lens and camera advice 
i've just some back from an amazing holiday in Uganda. I saw gorillas, chips, monkeys, lions, elephant and more in the wild. i've also come back with massive camera envy as the photos from my brother 350D are so much better than my little sony, 4mp, x3 zoom, so, having wanted to for a while i've decided to make the jump to dSLR.
The general advice seems to be stick with the nikon or canon, and the canon 400D and nikon 40D are good enough (and cheap enough) for what i need. I use the 40D at work and find it a little small and plasticy and the bottom left corner of the 400D a little pointy but out of the 2 the 400D seems better, so i'll go with that. Also brother has canon.
The camera will be used for a range of things from travel/backpack/holiday photos to general days out to some design/product shorts for uni, so animals, monuments, landscapes, people and products. In terms of lenses im looking for an all rounder to get me going, mainly cause in most of those situations im not going to want to change lens. So something starting at either 18 or 28 and going up to 200 or 300.
(i'm thinking i will pick up an wide angle, BIG aperture lens, for low light shots at a later date)
tell me if, and when im wrong but something to do with the camera having a x1.6 correction means you really need 18mm over 28 as a starter?
And seeing as there are little (or none?) 18 - 300 its going to be an 18-200.
seeing as canon dont make 18-200 that leaves me with sigma or tamron. (man in the shop said tamron was better)
So there is;
Sigman 18-200mm f/3.5-6.3 DC
Sigman 18-200mm f/3.5-6.3 DC OS
Tamron AF18-200mm F/3.5-6.3 XR Di II LD Aspherical (IF)
Tamron AF18-250mm F/3.5-6.3 Di II LD Aspherical (IF)
or any other people could suggest
im i right about needing to go down to 18mm?
is an F3.5 low enough for an all round lens?
which is better tamron or sigman?
which of those lenses would you recommend?
does the 400D seem like the right choice?
Thanks, and i look forward to posting some pics soon!
