Big Objektives

[kel_j_j]

Hi, I am new to photography and new to this website so Hi!! I have been photographing horse shows (mostly outdoors) and am slowly feeling like I am starting to get better. I am wondering if anyone can tell me a little about the massive big Lenses that the sports photogrphers have? I feel like a real rookie with my little nikon 70-300mm next to them and am wondering what the advantages are??

Help anyone?? I have a nikon d300 and my 70-300mm1:4-5.6D

Thanks in advance!!

The ability to zoom in and not lose any quality is a big one!

A constant f/4 or even f/2.8 and maybe even IS (or VR in your case).

The really big lenses are all primes.

Getting f/2.8 out of a 400 takes big elements, it's all physics.

Correct, but that big lens will reach further than a smaller lens and maintain quality

I dont really understand all the numbers and stuff. Like I said, I am really only new to photography so was just trying to work out what they do that is so good. Obviously they are good as all the photographers have them.

I saw one image taken with these big lenses and was amazed how much lighter the image was than what I had taken.

Thanks for your help! It is a little hard as I am in Germany and find it neally impossible to understand all the technical data in german. So being able to ask qns in english is a big plus!!

Thanks!!
