sigma 150-500 knackered. result- well done sigma.

And, by comparison, they are they are a lot better (and cheaper!) than Johnsons are for Pentax repairs
BTW: in case you did not know, that lens is just plain slow to focus "out of the box" because it has a very long focusing rotation and the mechanism is heavy - whereas the 100-300 F4 is the complete opposite = short rotational movement and much quicker to respond (especially with the K-3 & K-3 II).

I posted a while ago that my sigma 150-500 hsm os wouldn't lock focus. well, I sent it off and they replaced an mr sensor, but they contacted me and said that the lens was still "very soft", and they wanted to send it off to japan for recalibration, all included in the repair price of £146.
Sigma have just rang, and said that the lens cannot be repaired/re-calibrated to acceptable levels. they have offered a brand new, straight from the factory, 50-500 hsm os with a 3 year warranty as a direct replacement....only the repair fee to pay.
very happy with that.....
well done sigma uk.
