I recently bought Nikon D3200 with 18-105 lens. I want to purchase 55-300 lens to cover more range. I have come across three lenses which are
1. Nikkor AF-S 55-300mm VR f/4-5.6 DX-Nikon DX
2. Tamron SP 70-300mm f/4-5.6 VC Di USD Telephoto Lens
3. Nikkor AF-S 70-300mm VR f/4-5.6-Nikon FX &&&& DX
I am not sure which one to buy. Can somebody help in understanding the products. Between option 1 and 3, both looks similar to me except one is 55-300 and other is 70-300 mm. But 70-300mm is costlier than 55-300, I am not sure why. Please help in deciding me the lens.
From my research the 55-300 has a different focus motor (slower), less powerful VR and lesser optics. The reason for the price difference is the 70-300 being intended to service the FX market, hence the higher quality. The 55-300 is limited to DX applications.
