can anybody recommend a nice macro lens that's not too expensive for my cannon xti?

 

extension tubes would be the cheapest route.

if you want a dedicated macro lens, on a budget, Tamron 90mm

if you want to spend just a little more, Canon 100mm

granted, there are other ones but it depends what focal length you'd choose depending on what you plan on shooting.

 

May I suggest the Sigma 50mm f2.8 or any of Sigma's 1:1 macro lenses. I'm getting that 50mm next. Best of all, it's only $238.35 at Amazon. I like Amazon to B&H now, because you can send back stuff and Amazon will take care of the shipping if you have an issue, plus the prices are the cheapest around.

I have the canon 100mm f2.8 macro.

AWESOME lense.

The 100mm focal length is really comfortable for macro work. Gives you plenty of working distance.

 

i think i'm going to pick up the sigma.

thanks
