Yes, I've seen some photos posting around the net with that lens...they're so beautiful!
I thought it might be a good lens to have since summer is here and I'll be on road trips around the states.
Could someone recommend an ''everyday'' lens for me?
It doesn't have to be extremely fancy.
I'm just starting out and the 40D and sigma 10-20mm will be my first purcahse.

I'm so excited!
Sounds like you're really adamant about getting the ultra wide angle. That's cool, but I hope you either buy a 50mm 1.8 or the EF-S 188-55 IS because with only the sigma, you won't be able to shoot anything but landscapes and buildings. Because of barrel distortion, people will look streched out and awkward. The 50mm could be had for $90~ and the 18-55 IS could be bought for $120~. Both prices are considering if you bought used.
If you're a canon user, I really recommend the following forum.
http://photography-on-the.net/forum/Huge community of Canon shooters including hobbists and professionals. They are very helpful and friendly. Just be warned... they encourage you to upgrade and you'll find yourself being egged on to buying things that you've wanted. haha It takes some self restraint!
On a personal note, I decided to forgo my aspirations for the Canon 85 1.2. I just simply love using the 70-200 on 5dii for indoor portraits and can easily do without the 85. I don't do this for a living or get paid heavily so the primes can wait. BUT instead, I'm seriously eyeing the Canon 100-400 to use on my 40d and eventually 60d upgrade later this year. I'm finding more and more that I wish the 70-200 on 40d can zoom more and the 100-400 would be 2x the answer in terms of focal range. Sweet~! The aperture loss on the 100-400 is unimportant (4.5-5.6 vs 2.8) because at these ranges most of my shooting is done in the day time in well lit situations.
aw~ sorry to hear they you won't be getting 'the keg'. I hear it's an awesome piece of glass. But it sounds like you've already lined up your next gear, so I really don't feel that bad for you. haha
If you don't mind me asking, what do you regularly shoot that you find yourself going past 200mm on a 1.6 crop?
Hey, i'm extremely new to this thread and dslrs
but i need a new high quality camera so i was wondering if anyone could fill me in on the Nikon D40 and some good lenses to go with it.
Haha, i'm aware theyre pretty expensive but my budget is $600 for now.
(Sorry, if this has already been reviewed
)
thank you~ ^^ The Nikon D40 has been officially discontinued after the anouncement and sale of the D5000 but you might be able to find it in some stores still or buy used or ebay online.
Google 'D40 review' and you'll get more information you want. I good review site is dpreview.com. It gets very technical, but I trust that the most.
