Why would you use a 50mm lens?
50mm lenses are fast lenses with a fast maximum aperture. In fact, a 50mm lens allows approximately five times the amount of light into the camera’s sensor than a consumer-grade zoom lens. This enables the use of lower ISOs and faster shutter speeds so you can freeze motion and eliminate camera shake.
Why is a 50mm lens considered to be so versatile?
The 50mm is an example of a “prime lens”, in that it only offers a single focal length with no zoom option. This means to adjust the framing and composition of a shot, you have to walk closer to or further from your subject. The payoff from this is that prime lenses tend to be faster and sharper than zooms.

What does the objective lenses on the microscope do?
The objective lens of a microscope is the one at the bottom near the sample . At its simplest, it is a very high-powered magnifying glass, with very short focal length. This is brought very close to the specimen being examined so that the light from the specimen comes to a focus inside the microscope tube.
