Excellent pointMore range, has VR and he'll never have to change lenses ever again.
You need to take a look at the 28-300.
I think that it is a much better choice for you since you normally shoot around f/8.
Better reach, better price, better value.
When you need something faster, you have your primes!
I forgot all about the VR...
A 4 f/stop value in one (or two) easy payment.
Joke apart, I honestly think that the 28-300 is far more interesting than the 24-120.
