50mm Prime lens is also known as natural lenses as they let you see the world as-is in a full-frame sensor DSLR.
A prime lens is a lens with a fixed focal length and used to be the norm before the digital camera world was flooded with the zoom lens.
Zoom and telephoto lens offer the best convenience but it is hardly the best lens for a Digital SLR enthusiast trying to learn the ropes in photography.
Yesterday, I found the Canon’s nifty-fifty 50mm f/1.8 prime lens at an incredible price and that’s what prompted me to write this post.
Here are 10 reasons why every first time Digital SLR camera owner or a Digital SLR enthusiast photographer should buy a 50mm prime lens.
- Prime lens offer the best possible image quality at a focal length as there is less glass and hence low loss of image quality. They are known for sharp image quality and the bokeh effect.
- Cheapest prime lens like Canon f/1.8 50mm prime lens comes as such a fast lens – helps you shoot in low light because of the wide f/1.8 aperture letting in a lot of light!

- Wide angle lenses could be expensive but you can use your prime lens like a wide angle to get sharp pictures of landscapes by moving farther and using a high f stop.
- Street Photography – With the prime lens offering closer to what human eyes sees at 50mm or 35mm focal length (full vs cropped sensor), most people prefer prime lens for street photography.
- Bokeh or Shallow depth of field effect – you can use the wide apertures offered by the prime lenses to get great shallow depth of field as well as with lights in the background create interesting bokeh effects.

- Just get up close to your subject and shoot with your aperture wide open – you can get the same effect as a telephoto lens with your subject up close in the picture and the background totally blurred!
- Portait pictures often come out the best with prime lens as they give you the nice blurred background when shooting with your aperture wide open like at f/1.8.image credit: floodkoff

- Macro on the budget – just get a reversal ring and use your prime lens as a macro lens on a budget.
I hope these reasons were convincing enough to make you consider adding a prime lens to your digital SLR arsenal.
