I got this lens to replace 55-300 PLM which performed less then stellar for my uses. The result is kinda mixed, as image quality shot through the roof compared to 55-300, but AF speed sunk down Mariana Trench. But as I wanted more of IQ improvement I am more happy then not.
Build quality of this lens is superb. It looks, feels and handles like a premium lens despite being aged construction. Only cons about it's build is that it design looks old when compared with modern lenses. Not a drawback by any means, it is is that times changes and lens fashion too :)
Image quality - nothing to complain about. IQ-wise it is best Pentax DA lens I ever used. It is sharp, OOF areas render nice and smoothily, there is no deterioration when shooting at long distances (something that was a big issue for me with 55-300 PLM). Used on modern camera it performs as expected when it comes to DA* lens and it is pretty future proof I think.
Autofocus - now that sucks. Other then being silent there is really no difference in speed when I compare it with screwdriven Tamron. None. I cannot get why Pentax decided to mount SDM on this lens, but well. It is there. If you search for fast zoom to get most out of K-3 Mk III new AF module - look somewhere else.
Focus breathing - in my case I think at short distances this lens peaks at 150, maybe 180mm. Only beyond ~20 meters (more or less, never really measured) it is reaching up to 250mm focal length. Not an issue for me, I bought it for airshow and airpl... |
