Prime

Alex

Prime lens's, for those who not know, are a fixed focal length. Because of this uncomplication it enables better optimisation of the 'prime' focal element and allow a lot more light in therfore lower lighting photography can be done without additional use of flash etc.
I've borrowed a 50mm for a week, a crisp, sharp image they give, and I purposefully "miss" the focus to soften a portrait, they flatter more this way by the omission of any blemishes of the skin.
