What are the pros and cons?
Why do professional photographers cost so much?
That's a valid question and probably one I would ask if I wasn't a photographer. It may seems like you're getting exploited when it cost $500.00 or more for a one or two hour photo session, especially if the session doesn't come with any prints. How can photographers get away with charging $200 to $500 (or more) per hour and why do they do it?

An ND, or Neutral Density filter, works like a sunglasses, only it's for your camera lens.

The EF 85mm F/1.8 prime lens from Canon is great for portrait work. While it's possible to shoot just about anything with it, bear in mind it is a telephoto lens as well as a prime.
Need an affordable sports or wildlife super telephoto lens? The Sigma 50-500 APO DG OS HSM Super-telephoto lens might just fit the bill. The lens is light enough to use hand held but powerful enough to fill the frame with wildlife at a safe distance. What's best is that this lens is effectively an 80-800mm lens on a crop sensor body.
What is a STOP?
In photography a stop is the exposure value plus the difference of twice the amount of light to increase the exposure value. ½ the amount of light decreases the exposure value a stop. Fortunately, we can use the camera's built in light meter to figure out a given exposure value.
