Compare Pen 18-270mm with Sig 18-250mm.

Thanks, Ron.

I'd only switch from my sweet Pentax to this new lens if I knew that that was so. The relative lightness and compactness ARE attractive. My Pentax has quite marked aberrations, naturally, but these smooth out just fine in DxO with any newish Pentax body.
