The Pentax lens is another name of compatibility
The other day, when I was surfing Net, I found that there are numerous companies who are manufacturing different types of camera lenses apt to be used for different purposes. Nikon, Canon, Sigma, Pentax are few such names. Among all, I found Pentax lenses quite reasonably priced. They are highly compatible also, as its manual film lenses can be used with new digital SLR camera bodies. The company has provided its compatibility chart also to help us to comprehend which Pentax Lens is compatible with Pentax camera body or lens mounts. Each of its lenses has a different level of compatibility. It is advised to go through their guide once, before you select any lens for your camera.
