DSLRs have an optical TTL (through the lens) viewfinder, which allows you to look through the lens and see precisely what the lens projects onto the sensor. Viewfinders can be either optical or electronic. Pentamirrors are generally found on entry-level DSLRs and are constructed of plastic (instead of glass) because it is cheaper to mass produce. Pentaprisms provide a brighter image in the viewfinder than pentamirrors.

Pentaprisms are a higher quality than pentamirrors, which redirect the light through a series of mirrors. A pentaprism, found on professional-grade DSLRs, uses a prism to redirect the light from the lens to the viewfinder. The two main types of viewfinders are pentaprisms and pentamirrors. Additionally, when using the viewfinder you will have the camera braced against your body with your arms tucked in (instead of outstretched), which adds up to taking sharper images.
Looking through the viewfinder helps you stabilize the camera better. What you frame up in the viewfinder is the image – and memory – that you will be taking home. But it’s your eye to the world and the origin of your creativity. While your DSLR will get an overhaul from model to model with new and improved specs, the little viewfinder stays the same. That’s right, the viewfinder – the little rectangle on top of your camera. One of the most overlooked and taken for granted items on your DSLR is the viewfinder.
