16-50mm Da* Issues with KP body.

On my third one all from SrS in the UK.
All don't seem to wake up on first use, I have to focus n a near object then a far one a few times in order to make the lens focus. If I just oick it up and use it I get the flashing green square of blurryness, seems to be having trouble finding infinity off the bat so to speak. Similar to sleepy old SDM focus but all three have been bbrand new Ricoh UK stock. Anyone else having problems with this combo? My 50-135 Da* is unaffected.

But what does "brand new" mean. If you kept a track of the serial numbers and compared them with those in the lens databases it might give you an idea of age. They might not be new, as in recently manufactured, lenses. They might be a few years old.

Regards

Return. It only gets worse. I had the exact same issue when I bought it new at B&H Usa. I ignored it. Now this lens takes upto about a minute or 5 to wake up. It functions normally there after.

And my 50-135 is always hungover and sleepy and can take upto 10 minutes to wake up. Works after it wakes up. The wake up times vary seasonally. In summer or warmer seasons it is sooner. In winters it almost feels like the SDM is dead. But it magically wakes up at some point. But is sluggish.

They have some kind of Vitamin D deficiency may be.

It's on it's way back, I got SRS here in the UK to test their stock on the KP and they all do it!
So thats that then, so 16-85 or 20-40? All opinions are welcome.

I also have the 12-24 and the 50-135, so the Ltd would slot in nicely, however I've just picked up a bargain 21mm, which would immediately become superflous, so I'm leaning toward the 16-85 and picking up the cheaper green ring Ltd's as and when I can for a super lightweight and super quality kit for the mountain hikes,21mm F3.2/35mm or 40mm F2.8 (I don't macro!) and the 70mm F2.4,
these would pretty much replace the 16-50mm for lens speed...

Sounds like the SDM giving up, a normal occurrence with that otherwise lovely lens! My wife's did so, and never ever was as good as it used to be afterward!

Here in Sweden, the DA*55 WR has been withdrawn from sale after the importer had had heaps of those lenses with SDM problems.
