MF Portrait Lens

Hi everybody,,

I want your opinions and recommendations for a portrait lens for my Nex5.

I have the kit lens, and a 50mm MF, but wanted something extra for portraits. I read a bit, and consider that something between 85 and 90 should be the best thing for APS.c sensor. I know there are no rules, but that is a common recommendation.

So what are your recommendations for portrait lenses? In my case I dont mind that it is too big. Also I would prefer it fast, but it is not necessary the priority. My priority is a good quality for not so much money.

Thanks,
Ti@go
