Still a mystery I think, because have just reeled off another 36 shots - battery ok but not doing my shutter count much good

Hi Guys. No not in continuous mode, buffer not full,had some ev compensation on and a non pentax grip - but with no battery in it
Just tried to emulate conditions but everything seems to work ok. (Mind you not standing outside - too wet).

No problem focussing, in fact I had it on centre spot and the runners were coming towards me. It snapped into focus all the time - nice lense the 55 -300. Anyway that would not account for the LCD staying on after turn off.

Hi John, what I don't understand is that, on both occaisions, everything was working perfectly in the previous few seconds. so yes, battery etc were all ok.

Yesterday I was out taking pics (used K5 and 55-300), of friends running a half marathon. Found a good spot and took about 15 test pics to get lighting and angles right before my lot rumbled into view.

Got them in frame, pressed the shutter and nothing happened. Quickly turned off and on again and still nothing fired. Friends rumbled past.

Turned K5 off again but the top LCD stayed lit complete with data showing. Eventually had to take battery out to clear the display

Thought it must be a one-off so drove to another part of the course. Repeated test shots all ok. Friends rumbled into view and the bl**dy thing locked again. Again had to remove battery to clear it.

Has anyone else had this? It was a bit chilly but can’t think cold enough to cause the malfunction, specially when Gwyn nearly froze to death using her K5 in the Arctic.

Anybody got experience of this old manual lense (performance / weight etc)? Also would it go auto attached to a x1.7.

PM sent

I have a Tamron 500 c/w adaptor and hood that I am thinking of selling if anyone is interested

Thanks to all - obviously I will have to PP, but seems strange there is not an auto option. I am sure I have seen that on some cameras.
Thanks again

Some help please

I have searched the dreaded instruction book for the K5 and cannot find the answer to taking black & white (mono). In the digital filter set up you can choose some filters in set up but not mono. The set up for in camera post shot PP, does have mono, but does that mean you have to go back every time and use the digital filter?

Surely there must be something somewhere that you can switch to mono and just keep shooting – or do you have to use Raw and convert afterwards.

Any guidance would be much appreciated.

Thanks
