Canon EF-S 18-55mm f/3.5-5.6 IS6 out of 10 points and recommendedsolid baseunsellable
This one is "el cheapissimos sweet sister". The IS version of the most common kit lens ever. If you are lucky, you can find this one instead of the much worse non-IS in a kit for only very few extra money. It's a good base to start with an DSLR - good image quality and (as having IS) easy to handle. If you try to sell it once after you got a better one, forget it: eBay is full of people, who had the same idea.reviewed March 12th, 2010
Sigma 55-200mm f/4.5-5.6 DC4 out of 10 points and not recommendedcheapimage quality
You get what you pay - and that's not much. I first thought, I'm to stupid to get really sharp pictures, but the lens just can't do more than about 6 MPix. Also the minimum focus distance is very long (1.1m!).reviewed March 12th, 2010 (purchased for $180)
Looks like the Tamron with same spec and comparable price seams to be by far the better choice.
Canon EF 50mm f/1.8 II7 out of 10 points and recommendedpriceAF
The cheapest way to make portraits and to get used with a fixed focal lens. Quality is great, as long as you don't dare to go below f/2.0 (which is only very slightly darker than 1.8, so no real loss).reviewed March 12th, 2010 (purchased for $140)
The AF should be renamed to "AntiFocus" - if light is bad, you might guess better by hand. Things seam to get better around and above f/4.
