DA 40mm - optics and possible FF coverage

Hi,

I have the opportunity to bid on a mint used DA40mm and am very tempted. I've read that the DA40 covers FF (something I'd prefer in order to 'future proof' my lens collection). The author checked whether it vignetted on a Pentax film camera. This is very easily checked, but many lenses cover wider image circles than the format they're designed for. This doesn't mean that they deliver quality resolution out to the corners. Does anyone know if the lens does actually resolve well out to the corners of FF? Any film users tried it? Is the optical formulation the same as the earlier film 40mm pancake?

Thanks, Rod
