Moire Safe Lens Question

Hi,
I'm going to be filming an artist for a documentary I've been filming for the past year drawing in his studio next week and I'm looking to find a good prime lens or a zoom so I can get some nice overhead shots of the full drawing. I'm just worried about moire showing up so I was wondering if there are any tried and true lenses. I followed some forum advice before and got the sigma 20mm and the tokina 11-16 [which I'll be using for side shots and brush close ups]. The slight softness of those lenses has been great. No moire or aliasing at all. I was not so lucky with the sigma 18-35mm. I have a canon 18-135mm that I've used a few times , it had a bit of aliasing show up so it's sort of my backup plan. Are there any primes or zooms with a similar softness to the the sigma or tokina that are good at keeping moire at bay? Thanks!

Oh using the original EF camera

Have you tried being slightly out of focus with the Sigma? For a stationary object with lots of detail, I would give that a shot.

Oh no sigma works fine. My problem is I'm going to have to position the camera straight above the drawing so the camera will be fairly high up. I want to get the artist drawing and be able to get close up to sections of the drawing he'll be working on. I figured I'd need something higher than 20mm.

Sorry, I should have specified which Sigma I was talking about. I meant the 18-35. Wider than the 20 by ~4mm if you're accounting for crop factor. There's also a new Samyang 10mm f/2.8 that will be out any day now...

Ok I'll keep that possibility in mind. I've been looking at some vintage lenses like the Helios 77mm and 44m and an older Zeiss 50mm 2.8.

Have a look at Russian Mir 1B (37mm).

Awesome, I'll look into it.
