Well! After having the 35mm prime lens for a little while, I can say that it's almost constantly on my camera. I had a small shock and feeling of doubt when a uk Nikon publication binned it as its worst on test. However they were looking at bokah.
In low light conditions, the f1.8 comes into its own and I find myself skulking around at night or early mornings in my home town. A nocturnal photographer this lens is creating.
As for what is known in the UK as being a tackle tart. I've stuck to and will for the foreseeable future stick to the 35mm and the two kit lenses. The only thing that I might (if money allows) is up grade the quality of the kit lenses. The telephoto is are a bit sloppy when extended and creeps more than I would like. As an engineer type person I like close fitting interfaces and understand that you get what you pay for.
