Re: E-5 vs K-5 ii

So basically they agrees with my findings. The 60-250 is about as fast as 50-200 mk 1, but the 50-200mk II is way faster.

I haven't tried both, but Photozone has:


Just like its Canon and Nikon counterparts the Pentax' "Supersonic Dynamic" (SDM) takes advantage of ultrasonic waves to drive AF operations. The AF speed is relatively high although not substantially faster than a conventional screw-driven AF lens. If you listen hard you may notice a high frequency noise during operations but this is really not relevant in real world situations. Full time manual focusing, Pentax calls it "Quick Shift", is available in one-shot AF mode.


As mentioned the Zuiko relies on Olympus' new SWD AF for focusing. Typical for such ultrasonic-driven motors the AF operations are virtually silent. Usually (although not always) there's also a AF speed advantage compared to conventional AF motors - this is certainly true compared to its predecessor. In absolute terms the AF is very good but not quite as fast as on the Zuiko 12-60mm and about comparable to competing products. Full time manual focusing in single AF mode is possible.
