Pentax 18-135mm lens with K-01?

I'm looking at the 18-135mm F/3.5-5.6 lens and wondering if it works with the K-01, but the info I've found seems contradictory. On the lens review page it says, "Note: this lens uses the KAF3 mount. Autofocus will only work on SDM-enabled bodies: the Pentax K-5, K-r, K-7, K-x, K-m, K20D, K200D, K100D Super and K10D (w/ 1.30 firmware or higher)."

Hmm, no mention of the K-01 there. Does the K-01 have the KAF3 mount? I look up the K-01's page and it indicates a KAF2 mount. So, it would appear that the 18-135mm won't work with this camera, or at least not with autofocus? However... Next I go to the K-01 lens guide, and it says, "That's why we can recommend the Pentax 18-135mm as an all-in-one solution: you can't go wrong with its flexible zoom range and lightning-fast second generation autofocus motor."

Can somebody help me sort through this?

The DA 18-135 works with the K-01. Only old DSLR's, (*istD, K100D) have a problem with auto-focussing in-body lens motors.

Yes, K-01 can handle KAF3, KAF2 KAF, KA mount lenses (page 250 of the manual).

Ther's no reason you couldn't, but out of preference I just don't. If the K-01 was your only body, then that would be different. A K-5 is just a better choice for telephotos IMHO.
