24-70 f2.8 or 24-120 f4 vr11
Can I use the 12-24 on a D700 and what would be the widest zoom that I can use with this lens.I would keep my D300 as a back up body.
The 12-24 is a DX lens. You'd be able to use it in DX mode with the D700, but with loss of resolution.
The 12-24 covers the D700 sensor from 18mm on up. However, corner softness may be an issue depending on your needs. dave
