I'm relatively new to the forum and have what could be a silly question.
Although I've had my Pentax K-x for a while now, I'm only now looking to take advantage of all its benefits. So in the spirit of learning I picked up a 2.5/135mm Takumar Bayonet prime lens on the weekend to have a go at a fully manual lens. Prior to purchasing the lens I knew to expect that due to the APS-C crop factor the 135mm Takumar would give an equivalent focal length somewhere jsut above 200mm.
In toying around with the lens I was looking to compare the image quality with my Pentax 50-200mm kit lens and found the 135mm Takumar to take photos with an equivalent field of view to the Pentax 50-200mm when the latter was set to 135mm of zoom.
Am I missing something? Was I wrong to expect the Takumar to have a smaller field (greater focal length) of view than the pentax set at 135mm?
