However, the lenses of the same zoom range of different distances?
Why is that a lens like the Nikkor 70-200mm f/2.8 VR has the capacity zoom beyond saying that the Sigma 70-200, f / 2.8 EX range of 70-200 is the same … however, the nikkor you closer to what this is? I do not know … is difficult for me to explain just seems, with some of the paintball photography i do, and I see other people with the same rank (as I said 70-200) can get things through the field, while it seems that I can only get good shots to about midfield ..
As previous posters said, should not no difference between the two. I will insist that there will be a difference if someone is shooting a full frame camera and the other is not. The full frame camera-no will have a multiplier of 1.6 x lens actually goes to 320 mm. Another possibility is that the other person is using an extender. Tubes and can be ad-ons that will extend focal length (usually twice).
