Also known as nifty fifty, the Canon EF 50mm f/1.8 II lens  replaced the Canon EF 50 mm  f/1.8 in 1991. This particular lens is made with a plastic lens mount and it does not come with a distance scale. It also comes with an IR focusing label and a dedicated manual focusing ring so that you have more control with your camera’s focus with it.  The focusing ring is very thin and is found the front tip of the  lens. What makes the ring great is that you can also use the tip if you want to attach polarized filters to it so that you can control the glare in your subjects especially when you are out shooting under harsh direct sunlight.

On the other hand, similar to the Canon EF 50mm f/1.8 lens, this lens has an optical infrastructure that comes with six elements in 5 groups as well as a 5 blade diaphragm. What makes this lens great is that its focal pint matches the field of view of the human eye so you get great images all the time. The lens also comes with an APS-C sized sensor thus photographers need to apply a focal length multiplies which is also called as the crop factor if they want to get an effective 35mm field of view equivalent.

 Now what makes this lens great is that just like its predecessors, it is also relatively cheap which earned its name as the nifty fifty. It owes its cheap price to the six blade elements which is fewer compared with the other types of lenses with the same focal point. The lens has a very lightweight built and it feels more like a toy than a lens.  In fact, this type of lens is considered as the lightest and shortest lens Canon has created so far.  When it comes to image quality, this particular lens offers a shallow depth of field (DOF) which makes it very great if you want to isolate your subjects from the background. This is a great lens if you want to focus on both product and portrait photography.

 Due to its lightweight built and cheap price, this particular lens is a great option if you are looking for an inexpensive lens  that you can take anywhere.  Below are the specs of this lens:
