I have found myself in a total rut lately so I have decided to embark on a themed project. Some of the shots will be portraits hence the questions today. I would love to spend a small fortune on lighting but will attempt some of the DIY options first. I currently have the 18-55 mm kit lens along with the AF-S DX Micro-NIKKOR 85mm f/3.5G (1:1 max reproduction). I'm looking to pick up a new lens for my endeavor and have narrowed it to the four options listed below. Shooting in low light is an important consideration but not necessarily my first priority. I have the Nikon D5000 which is a DX body.
AF-S FX NIKKOR 50mm f/1.4G $485 US
Fastest but most expensive. Great reviews.
AF-S DX Micro-NIKKOR 40mm f/2.8G (1:1 max reproduction) $280 US
Not as good in low light but having another Micro lens would be nice.
Could it serve a nice dual purpose for Macro shots and portraits?
AF-S FX NIKKOR 50mm f/1.8G $219 US
This new introduction from Nikon has received great reviews for portraits.
AF-S DX NIKKOR 35mm f/1.8G $200 US
Again great reviews. 35mm DX v. 50mm FX???
Any Nikoneers have experience with these lenses for portraiture?
No need to get into scientific discussion on crop factor or FOV with an FX lens vs. a DX lens on a DX body per se, but your general thoughts on the matter are most welcomed.
