According to my experience photography is all about understanding the light, movement, and subject of what you photograph.
Photography is request a lot of time in practicing and learn about what you photograph
Gears are important as well because to capture the light and movement ( you should understand your camera, lens, and other accessories.
Depending on the purpose used For example: if you would like to capture birds in action you may have to use a high-speed shutter camera and a lens is important as well (this option is more professional photographers)
but if you would like to use a camera for identification you could stay with low budget Ex: Nikon p1000
Now I'm still using Nikon D700 with Sigma 150-600mm f/5-6.3 DG OS HSM for Photography identification, it is very helpful
