After searching a lot, I find this online store lists the lowest price of Canon EF 50mm f/1.8 II Camera Lens all time.
If you want to buy a lens with great quality and low price, the Canon EF 50mm f/1.8 II camera lens would be your best choice. The 50mm lens is the standard camera lens. The Canon EF 50mm lens is very sharp when stopped down. It shows minimal chromatic aberration with relatively low disortion. If you are a APS-C user, you could benefit from low vignetting of this lens. You can even use this lens like a toy. It use plastic construction so that it is only 4.6 ounces weight. It is the lightest and smallest lens of Canon currently. A micro motor works for autofocus so the focus speed is fine in bright light with common subjects. The only disadvantage of Canon EF 50mm f/1.8 II camera lens is that it is a little noisy when focusing. I don’t think it could bother you because the time of focusing is very short. This lens is very sharp at f/2.8 and beyond. It is even sharper than EF 24-70mm f/2.8L usm lens. I’m sure its a fast lens which has an f/1.8 maximum aperture. if you are taking pictures of people, this lens is unyielding in its sharpness and may well surprise you and your subjects whose every blemish is captured. The Canon EF 50mm f/1.8 II Lens takes the optional ES-62 Lens Hood that includes the Hood Adapter 62. The hood adapter threads onto the lens – the hood then attaches to the adapter by pinching two latches. If you mount this lens on a small DSLR, you will get a camera lens with smallest, lightest but at lowest price. I’ve now had this lens and used it fairly regularly (although not as the primary lens) for about 8 years and it is still in great condition.
