Cheapest Nikon Lense?

I want to know the cheapest macro and wide lens for Nikon D7000

The Nikkor 40 mm macro lens is the least expensive.

Here is a link to all the Nikkor lenses and what they cost.

I'm surprised you did not check the Nikon website first.

Cheapest macro - Sigma 50mm f2.8 macro.

Cheapest wide angle - Sigma 10-20mm.

I have both which I use on a D300. They both perform excellently. The 50mm macro also makes a great portrait lens.
