Equestrian Photography - Buy the Best Body and Lens You Can Afford
Unfortunately an expensive camera does not take a good picture alone. However, you can’t make a good picture without a decent camera, so you should always try and buy the best you can afford. Make sure you do your research to ensure the camera you choose is able to do everything you need it to.
Arguably almost more important than the body is the lens that you use. Ask any major equine photographer and they will tell you a 70-200mm f2.8 is the lens they use 80-90% of the time, it is a real work horse (excuse the pun!). The reason being is that the lens has both the zoom you need for shooting horses and the settings to shoot indoor arenas and other low light situations without having to use artificial lighting.
Of course, none of these will work unless you do your homework - I love this quote by Henri Cartier-Bresson
“Your first 10,000 photographs are your worst.”
So guys, practice, practice and practice again :-)
