"Nikon D5100 basic question about lens"


US
          

Hi All,

I have question regarding buying D5100 with lens.
I am interested in 2 choices to buy along with Nikon D5100.
1) Nikon 55-300mm f/4.5-5.6G ED VR AF-S DX Nikkor Zoom Lens
2) Nikon 55-200mm f/4-5.6G ED IF AF-S DX VR Nikkor Zoom Lens

My question is why 55-300 have f/4.5 instead of f/4.0 ?. If I want to take pictures with Shallow of Depth does this matter ?. I just want to understand how the f/4.5 - 5.6 in 55-300 is different than f/4 - 5.6 in 55-200 lens.

Which lens is better and what is pros and cons of each ?

Thanks

The 55-300mm maximum aperture at 55mm is f/4.5, 1/3 stop less than f/4. That's just how it's made. Neither f/4 or f/4.5 is a particularly wide maximum aperture, so you're not going to be able to get as shallow DOF as you would say with an f/2.8 zoom. The DOF difference between f/4.5 and f/4 isn't going to be much.

At their maximum focal lengths both lens' maximum aperture is f/5.6. At 200mm, the 55-300 will have a slightly wider maximum aperture than will the 55-200mm at 200mm (probably about f/5 vs f/5.6),
