Its not often that I get excited about lenses as such, but I have been busy shooting portraits shot with this lens and I have to say I am seriously impressed now that I am producing darkroom prints. Sharpness is fantastic and the general look is just perfect for portraits. Most were shot at F2 - F3.5 but those shot at wider apertures are wonderful too. One frame shot at 1.2 or 1.4 (can't remember) has a particularly special look to it, which is not all about shallow DOF, but rather a slight glow. Its hard to describe but presumably due to some sort of aberation or other (spherical?). its very subtle, but there. I did not expect to be excited about the character if this lens when shooting portraits at anything other than 1.2, but I am amazed by the superb contrast, sharpness and impecable OOF handling of this lens no matter what distance, magnification, aperture, lighting etc. After trying a few 1.8 EF lenses that had problems straight out the box, I bought this as I needed it urgently. All I can say is I won't be trading down when this project is done. This is one hell of a lens... (if only it was half the weight! That said, my favourite portrait of the lot was shot right on the shutter speed threshold in very poor light at 1.2 or 1.4 (can't remember which) so I would not have this particularly special image were it not for the speed. So far the somewhat average close focus has not been an issue either.
