Wider prime for Nikon DX?

[squerble]

Hey all.

I'm very new to photography (recently got a D3200 with 18-55mm, 35mm f/1.8 and a 55-300mm on the way) and I'm wondering why Nikon don't seem so offer a cheap 22/24mm prime like they do with the 35mm. The 35mm f/1.8 DX is getting a 52.5mm "equivalent" on a full-frame camera (1.5x crop) and I'd need a 22/24mm prime to get the 35mm "equivalent". I know I have the kit lens and can get that to 24mm but I'll be limited to a minimum of f/4 and while that isn't too bad, I guess it would be nice to be able to drop a couple of stops to f/2 or lower.

Does anyone know of such a prime for a DX Nikon?

Cheers. That Sigma definitely looks great but quite expensive. One for the future I think - my photography is absolutely pants at the moment and I think I've got a decent range of equipment to get plenty of practise with for now.

I just expected that Nikon would have a "cheap prime" for the wider end like they do with the 35mm f/1.8 given the crop factor.
