KAF3 - now the official name for SDM support?
Hi all, is KAF3 the official name now? Is there any change, other than adding support for SDM (Supersonic Drive Motor) support? http://kmp.bdimitrov.de/technology/summary/index.html ends at crippled KAF2 for 1997. It does name the latest models up to the K20D, but does not name the K-m (K2000D) yet. It does not differ between KAF3 and KAF2. Same for e.g. dpreview.com: they did not update the specs for K10D (after firmware update), K100D super and upwards.

Mess. K2000 names the KAF3 lens mount (for the body itself!) - and names compatibility for KAF2. Scroll down that page and you'll see the camera mount is stated to be KAF2. I doubt that KAF3 would be KAF2 without mechanical AF drive, but it's hard to say as long als Pentax messes up those things themselves. I fully agree.

Just look at the endless mess they did by not distinguishing the "crippled KAF2" from the "true KAF2" and you'll have no more doubts about the ability of Pentax to mess up things. All that mess produced in Pentax instruction manuals and public knowledge - just because a marketing genious didn't want to give different names to different bayonets - will never cease. At least this time they introduced the KAF3 name...

Re: KAF3 - now the official name for SDM support?
Martin, I agree it doesn't make much sense on the camera side of things except to state the range of compatibility. On the lens side of things, KAF3 means that it won't AF with a KAF2 camera. When a camera is described as compatible with both 2 and 3, I assume it supports lenses with either shaft-driven and the SDM AF. I wouldn't expect PowerZoom functionality, though, which is what the SDM contacts were used for in KAF2. Still with the reservation of having got this right myself... :-) If you look at the joint press release for the 55mm and 60-250, for example, the prime is KAF3 and the zoom KAF2, but both have SDM.

Re: KAF3 - now the official name for SDM support?
Martin, I think the official thing about KAF3 is lack of support for camera-driven AF, leaving the lens or camera with SDM as the only means of AF.

Re: KAF3 - now the official name for SDM support?
KAF3 is SDM-only interface (see the DA 17-70mm). Currently, it's only been implemented on lens side, but there's nothing preventing it to show up on cameras too. Nikon has done something like that with the D40 series.

Upper or lower case, with or without dashes, maybe it's all the same for a company which is used to Japanese text. -- Pt! Schon vom neuen GMX MultiMessenger gehört?

Martin Trautmann wrote: side note: pentax.de names SDM as Super Dynamic Motor (google: 18 instead of 88 hits) Pentax De has a weakness for changing names. They dubbed as "Limited Edition" those lenses released by the parent company as just "Limited", and then they interpret SDM as "Super Dynamic Motor" instead of "Supersonic Drive Motor" or just "Sonic Drive Motor" (as stated at the press conference in Dubai) last January. I'm afraid that Pentax never ever will learn how to use matching names for their products. Upper or lower case, with or without dashes, maybe it's all the same for a company which is used to Japanese text. Yes, I believe that the Japanese people of Pentax don't care so much about latin-spelled names for their product. That will explain how can they even allow name changes by the funny volks at their subsidiary in Hamburg.

I stand corrected: the KAF2 down there refers to the DA L 18-55 lens. In any case, the K2000 is KAF2, not KAF3.

But the prime has NO drive-shaft. Live with it, KAF lenses are LESS capable than KAF2 ones are.

Exactly. > Live with it, KAF lenses are LESS capable than KAF2 ones are. > (allthough they could be faster at what to can do, SDM) :-) I'm not whining. SDM is worth it. I look very much forward to testing SDM performance in the cold. As in -10 °C and lower. I expect this system to be vastly superior to the shaft-driven AF with manual touch-up. In fact, that's my main gripe with the trusty old DA 16-45/4 zoom; the AF could hardly move in the cold. The reason was that the friction in the system became too strong when the materials cooled. Warm batteries didn't help one bit either.
