Trying to decide which DSLR camera to buy? One of the considerations to ponder is whether to buy a crop sensor camera or a full frame camera. Or perhaps you're considering upgrading from a crop sensor camera to a full frame camera.
Sigma considers this lens as one of it's Flagship lens. Inspite if that here are the pros and cons of the 35mm F/1.4 Art lens
What are the pros and cons?
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?

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.
