My DA*60-250 zoom ring rotates from 60-250, but the lens does not extend much from 200-250 - about 3/16". The exif agrees with the zoom ring. But testing against a 55-300 lens it does not appear that it is extending much past 200. I purchased used. Does this sound like a case for Pentax service? . Or is there anything I could try myself without a good chance of munging up the lens?
I tested by placing the end of each lens at the same spot, focusing on the same object, and taking a series of pics with the increasing focal lengths. When comparing it appears that the DA*60-250 begins to fall behind the 55-300 at around 150mm and pretty much stopping at around 200. (I am assuming the 55-300 is correct - it at least extends at the same rate thru out when turning the ring).
Any ideas before I ship to service? (depending on cost, I could have purchased a new one
)
Thx
