Well, I've never agreed with the just as good and indeed we've had figures from tests provided in the past. Very few batteries deliver their specification, but the Pentax ones did. The Inov8 I seems to recall were relatively disappointing. Not bad, but not exceptional.

I've not worn out a Pentax Lithium battery pack yet, but I don't shoot the vast number of images that some of us do. I do rotate the batteries in use though and this seems to be enough to keep them in good fettle.

Moved to Classified Ads.

And the image, shot on the Q with 5-15mm lens:

Here's a picture, shot on the Q with the 5-15mm lens:

They aren't picking on you in particular, they just don't really understand....

All the batteries have a finite life and will only take a certain number of recharge cycles. I would try each one separately in the camera without the grip and see how they last then. The faulty one may be determined and then replaced.

Boxed and mint, used very little, some re-arrangement of our cameras leaves this currently unused. Everything is in the box, plus the bonus of an extra Pentax-branded battery.

Price is £55.00 and postage rates are as follows:

UK SD: £7.00
EU Airsure: £13
Rest of the World Airsure: £18

I'll try and post a picture later, but for now, one beautiful condition MkI version of Tokina's 80-400mm lens, complete with original front and back caps, original lens hood and original case.

We have two of these and it's turning out that we don't really need to use two at the same time. Something has to give to pay for that Q!

Price: £350.00 fully insured to anywhere in the world.

I understood there were strict rules about photographic evidence, in terms of focal length, an indication of scale, direction shot, etc. The document I read (which may or may not be what happens currently) was very specific about the requirements.
