When and where did you purchase it? It might have a two year guarantee and the camera wasn't released until 2015 so many must still be in warranty.
You could ask SRS about repair but I'd expect then to send it to the official Pentax repairers who are Johnsons Photopia Ltd, Hempstalls Lane, Newcastle under Lyme, Staffordshire ST5 0SW Tel: +44 (0) 1782 753350
Email: [email protected]">[email protected] so maybe better to deal directly.

Alan Marlow of Shepperton might deal with it too: http://www.cam-rep.co.uk/ at a more favourable cost.

Given how common this problem is, it's clearly an inherent fault that shows up in several Pentax models including the K-30, K-50, K-70, K-S1, K-S2 so Ricoh ought to do the responsible thing and sort the problem out for affected owners FOC.

There are home remedies in various forum threads such as this:

The camera should be expected to last for a reasonable period of time. If it really worries you you have six years to take a claim to the small claims court for faulty goods in England, Wales and Northern Ireland, and five years in Scotland. For help with this see https://www.citizensadvice.org.uk/law-and-courts/legal-system/taking-legal-actio...

Someone here got it fixed by Pentax outside the warranty period. See https://www.pentaxuser.com/forum/topic/the-dreaded-k30-aperture-motor-failure-st...#comm589524

I suppose it could be the aperture motor problem, same as experienced by some with their K-30s. If you have any warranty left on the camera, get it sent back for repair before the guarantee runs out.

I'd have trouble recomposing the photo in the frame to take another one repeatedly in under half second intervals.
Surely a seconds worth of photos at 7fps means they must be almost all the same so does it matter how many it takes? If it's to capture a specific instance in an explosion or something video or dedicated hi-speed camera is the way to go.

Beware of snipers wielding one of those. You may get mistaken for a terrorist!
Far as I know it's only 500mm at maximum zoom.

The one that got away!

... and camera posted!

Not at all bad for a couple of hours work yesterday Alan. Super shots.

PM sent.

Hi,
I've got two original Pentax Q's and a Q7. I'm happy to let one of the original Q's go but I don't think I have a spare lens for it (I'll check in the morning.) If I remember correctly, one came with the standard prime and the other the standard zoom and I still wish to retain both lenses. The spare Q is mint and boxed in virtually brand new condition having been kept as... a spare! I have a DA 16-85 so wouldn't wish to swap!
Would you be using the Q with a normal DA lens + adapter to capture your kingfisher?

That's a Claas act!
