Canon, who any camera enthusiast will love, or at least respect (Nikon fans), make great lenses as well as cameras. The battle for market dominance among the entry level and mid range DSLR models is becoming heated, and the same applies for the lens market.
This 50mm lens, although a fantastic lens for image quality, and exceptional value, is a (mostly) plastic made lens, and as such, it lacks the durability of Canon’s higher end lenses. Obviously the price of the higher end lenses scare a lot of people away, myself included, but this, although cheaper lens, is still great value.
Unfortunately, some of the internal threads have given way in this particular example, causing the lens to stop functioning completely. Rather than a costly replacement, one of our engineers was able to get the lens back up and running, as good as new, within a day.
