So to round off the 'collection'. Comes in a very decent carry bag/belt pouch But at 520 gms, it isn't exactly a lightweight lens. Vs the 18-300 - Parting shot - After reading about the Sigma 10-20, the price point and the performance makes it for a sweet deal vs the Nikkor 10-24. The Nikkor lens is more than double the price, and offers comparable performance. Now for some test shots when I get a chance.
