i just started with photography. I have a 50D body on hand.(originally I want a 550d but i got a discount only for 50d for $800). And I am planning to get the prime lens 50mm to start with. and maybe a zoom lens too.
Can anyone give me some advices on what lens I should start with?
Sorry to ask dumb question, most ppl get their dslr with a clue what lens they shld get but i am too new to this field.
I think everyone has had some great suggestions, but I'll show you my choice and explain why I personally would pick it. I like the Tamron AF 28-75mm f/2.8 SP XR ZL Di LD Aspherical (IF) or Canon 24-70L. The Tamron is my everyday lens. It is a pretty fast lens, with image quality almost comparable to Canons similar L series lens, at a cost of $450 instead of $1200.
I have the 50mm prime lens mentioned here, but if its your only lens, I wouldn't pick a prime lens. I personally don't like the 18-55 because of the lack of closer zoom, and the fact it's pretty slow especially in the upper ranges of the lens. It has IS, which of course is nice, but that's not going to help you much on moving scenes. It is much cheaper though, at $150. The standard lens that comes with the 50D is nice, the 28-135 IS canon lens. It would be my second choice, and can be had pretty cheap on ebay, or on amazon for $350.
The other reason I choose this lens is for future expansion. A lot of the L series zoom lenses from canon start at 70MM, and the wide lenses go up to the 20's, so it works well as a compliment to future lenses.
If you can afford the $1200 for the Canon 24-70 go for it, if not, I'd go with the Tamron.
This is my very unprofessional opinion.
