I like to read up on photography blogs, tutorials and anything to do with other people's experiences of photography. The stock lens that came with my camera is excellent. It is the 18-105mm VR kit lens. A great utility lens, let down only by the fact that it has a plastic mount rather than metal.
In any event, it seems that there is a universal suggestion as to what lens an aspiring photographer would move onto next. These are known as prime lenses and in simple terms they are lenses with a fixed focal length as opposed to being zooms. There are varying options available, but it seemed to me that the cheapest and most sensible step would be the Nikkor AF-S 50mm 1.8. This model can be had for around the £100 mark and they are praised worldwide.
It seems that the prime lens is something of a purist lens. The luxury of a zoom is gone and to compose your photos the way you want involves you physically having to move around the environment to get the right shot. On the D90 the 50mm works beautifully in low light without a flash, has a very quick focus and the shallow depth (Bokeh) looks amazing. In fact you need to try hard to stop every photo looking like you were trying to achieve some kind of artistic masterpiece.
I found the you gained a great deal more control close up as to what area you wanted to achieve focus.
Below were the first attempts when messing around with the new 50mm lens:
(You will notice that there is a distinct lack of sharpness to the pictures. This is not the fault of the lens and will be covered in another post)
So this is a good example. The three very small figures are stood in close proximity and yet the lens has no difficulty in focusing on the middle figure and giving a pleasant blur to the other two. Of course when trying to be too clever with manual focus this can go wrong as you can see with the next attempt:
This was an attempt to focus on the queen of the lego people. Sadly I actually ended up focusing on the backside of the two nearest genuflecting characters. Nevertheless it does demonstrate just how finely the focus can be used.
Ok the final test shot shows the fun you could have with a lens like this. Please ignore the softness of the picture:
