Now your FF 70-200mm lens f/2.8. This is a classic in full frame land. Its a big, heavy, fast lens, with good IQ. But we already have a 70-200mm f/2.8 lens that has fantastic image quality, is fast, is weather resistant, is really of higher build quality than most 70-200mm lens on FF bodies. We have the DA*50-135mm. If you do the math that equals a 70-203mm or lets just say 70-200mm. Why do you think Pentax made that lens with a strange focal length of 50-135mm!

But the 50-135 is pretty slow focusing lens ad not suitable for fast action. And used to be susceptable to motor failure. I sold mine due to the motor failre. Other than that is was a excellent lens
