Yello !

I'm a newbie and taking my first baby step into photography: buying my first gear.
I've read a lot of review but I think the first problem is lack of actual experience.

I've researched and decided Canon EOS 550D is the way to go (Sorry Nikon enthusiast) because I am interested with astrophotography and Canon gear can integrate easier - unless i'm mistaken

OK.

Now the real question.
I have the option to get the kit lens 18-55 f3.5-5.6 IS lens or squeez more a little more blood and get Tamron AF 17-50mm f2.8 XR Di-II LD


So should I just squeeze it or get the kit lens?
