Input:
I bought my 28mm F2.8 lens second hand for about 120 dollars and it came looking brand new with a filter! I used it on my (second hand) D700.

When my daughter was born, I was allowed to take my camera in the delivery room and I had to take one lens with me. I chose the 28mm f2.8, that says it all!

My other lenses were the 50mm f1.4G, 20mm f2.8 and 24mm f2.8.

So why the 28mm?

1) Autofocus is extremely fast and precise and I didn't want to miss the shot of the birth (unlike the 50mm f1.4G that chases around the focus point a lot).
2) The lens is super sharp wide open at 2.8. If you check on dxomark.com you will see that the 20mm for instance is sharpest at f4.0, while the 28mm is sharp already at f2.8.

Other strong points, less relevant are:
3) cheap
4) small and light

Overall, this lens was a big positive surprise for me, because I had read so many negative reviews about it.

I would only use this on FX, on DX go for the 35mm f1.8G.
