Almost everyone sells something online from time to time. Digital presentation can be a determining factor for success in those cases. How do you present your products the best? Every detail in the photo tells something about the product that you're showing to your customers. Product photography is a profession in its own right.
There are no specific requirements for your camera and lens in product photography. However, a good product photographer knows that the product must be captured as detailed as possible. They often make use of the aperture, because the blurry background will make the product stand out that much more. Don't make it too hard on yourself, because for product photography, the motto is "less is more".
