Can you return it? Or is there a warranty?

DA 55-300mm will not focus on K70 body with any settings
How about taking it back to the shop to try it on another body there? Even if it's out of warranty they might help you out. Or maybe you can find another Pentaxian close by who's willing to provide another camera to try it on?

DA 55-300mm will not focus on K70 body with any settings
If you haven't had it very long, haven't used it heavily and haven't dropped it or done anything else that might damage it internally, then I would go back to the shop with camera and lens and say 'look what's happening'. You don't say whether you are in the UK or not, but consumer law in the UK doe...

This may be of no use whatsoever, but I Googled your problem and came across this "This specific lens features a collapsible retraction mechanism to save space.Action: Ensure the lens barrel is fully locked into position at the 55mm mark. If the retraction button or locking mechanism fails, the ...

DA 55-300mm will not focus on K70 body with any settings
Was this returned to MPB? I see they have one as spares/repairs. I'd love to experiment on it. It's likely to be a ribbon failure that is causing glitches, so my thought would be to try and bridge the ribbon to get rid of the 'lens retracted' check.

Pentax HD DA 16-85mm F3.5-5.6 ED DC - Autofocus failing at most focal lengths
Hi, my 16-85 has suddenly developed autofocus issues. It has always focused really well but has suddenly started to completely fail to focus at most focal lengths both through viewfinder and live view. It seems to focus fine at 85mm and it will still focus occasionally at 16mm but will not focus mos...

Pentax HD DA 16-85mm F3.5-5.6 ED DC - Autofocus failing at most focal lengths
It won't be a motor issue in my experience. My bet is on the forked contacts being bent out of shape or perhaps a ribbon that has disconnected due to a slight bump. I had a 16-50 that would refuse to focus correctly recently, and a quick disassembly of the rear showed that one of the main ribbons...

Pentax HD DA 16-85mm F3.5-5.6 ED DC - Autofocus failing at most focal lengths
My 16-85mm did have occasional problems focusing at 16mm. It would appear to focus and then confirm with a beep but I could see in the viewfinder it was out of focus, but that doesn't sound like what the user is experiencing here.

Just an update on my lens for anyone who has a 16-85 and faces a similar issue in the future: I haven't heard anything back from 1stAid yet. Sent the lens to John Pye.

Ricoh GRii - RIP - HELP!
The build isn't really in the rugged and tough category so given the adventures it has been through i think it has served you pretty well - your photos speak for themselves (although as always a great deal of that is down to the photographer rather than the equipment) and I think you'll probably hav...

A problem that wasn't
Just in case anyone else comes upon my recent problem .... I changed the lens on my K1 and, as I often do, had a quick look through the viewfinder. It was out of focus so I half pressed to engage the AF. It was still out of focus. Oh Sh**! I checked everything and tried a different lens. Just the...

Clearly the deciding factor in your in depth investigation into the root cause was the Beer - you've changed my life, I will always fall back to your approach for any problems in future :wink:

A problem that wasn't
Most people will tell you not to touch the wheel after a drink but in this case they're wrong... I have had this happen to me. The wheel on my S5 is too easly moved so I long ago covered it with some black electrical tape, which is barely noticeable. I once had a similar problem on one of my ...

K-5 and Novoflex long lens.
I have an old Novoflex slide focus type lens. It had no objective lens when I got it so I made a lens cell with 80mm diameter 750(?) lens. A vistant object focuses good in the view finder of my K-5 but the picture is very poor. I know about vibration etc but I wonder what settings I should have ...

Pentax GPS Unit Review
I was disappointed to see it omitted from the K-3iii, it seemed sad that you had to give up both the built-in flash and the GPs unit for the K-3ii. That and the fixed rear screen prevented me from parting with my K-3 ii and K-70 in part exchange for the K-3 iii. Pentax seem to take two steps forwar...

Do you have a question for the Pentax team of experts?
As a loyal user of Pentax equipment I'd like to see some of the firmware functions found in current models appear in updates to more recent, but no longer current models. Focus peaking is one that springs to mind, I'm sure others can think of some more. I'm not talking about retrofitting new ...
