Hi guys! New here I'm buying my first SLR, the Nikon D7000 kit with the DX 18-105 VR lens. With it I have the option to take another lens with some serious discount. These are my options: Nikon AF-S DX 18-55 3.5-5.6GII, Nikon AF 50 mm 1,8 D and Tamron AF 70-300 F/4-5,6 LD Makro 1:2. Which one, if any of these would you recommend? The point being, I guess, something that would compliment the bundled 18-105.
