Hi John,

I changed the battery half way through the meeting. I tried another fully charged battery and it's still the same.

Hi David,

It was around 700 shots over about 4 and a half hours. I have the camera in front of me right now and it's still not working.

Regards,

Chris.

Hi again,

Well it's happened again today ( at the same stock car track too ), camera locked and battery depleted message on the rear screen.

The strange thing is this....the first time it happened I had taken around 700 shots, today I had also taken around 700 shots too ( good job I took a spare camera with me today )

It's looking like I'm going to have to send it in for repair.

Regards,

Chris.

Thanks Stephen.

I wasn't using 'Live View' David.

Thanks John,

I'll give the contacts a good clean and see what happens. I'll take a spare body with me next time.

If it is the mirror motor does anyone know an approximate repair cost?

Thanks all for your replies,

Regards,

Chris.

Hi all,

I was at my local stock car track today doing infield photos when my K5 suddenly stopped working.

When pressing the shutter release button nothing happened, the top screen went blank and the rear screen said 'Battery Depleted'.

I tried both my fully charged spare batteries ( both genuine Pentax ) but it still didn't work.

When I got home I removed the lens ( 50-135 DA* ) to see if anything was amiss inside the camera body, on replacing the lens the camera started working again normally.

Has anyone else had this problem and if so is there a fix?

Regards,

Chris.

** UPDATE **

I have now received the lens back from Sigma.

The enclosed paperwork said that after initial testing no connection issue was found.

The work carried out was - repair zoom, check mount, reset, check & test.

I gave the lens a good testing today ( over 1000 shots taken ) and it worked without a problem all day.

Not sure what Sigma have actually done but it seems to have worked, for the time being at least.

Regards,

Chris.

I decided to give the Samsung GX10 a trip out at the weekend, I haven't used it for ages.

These were taken using the Sigma 18-250 OS HSM that I have just returned to Sigma for a warranty repair ( see Troubleshooter section )

They were taken when the lens was working correctly.

The 18-250 doesn't have an aperture ring.

It has now been posted back to Sigma.

Regards,

Chris.

I have phoned sigma just to confirm that the lens is still covered by the 3 year extended warranty and it is, until September.

They told me to package it up and return it to them for repair.

Thanks for the replies.

Regards,

Chris.

Hi all,

Lens - Sigma 18-250 OS HSM

The lens isn’t showing the F Stop information on the camera display, the display just shows F---- and the images come out very, very white.

If I press the lens release button and twist the lens a quarter of a turn then turn it back to lock it back onto the mount again the F stops work as they should and the images are as they should be, this lasts for a good number of shots before the fault shows up again.

I have cleaned the contacts on the lens but it's not helped any.

The fault seems to be intermittent but I have tried the lens on my Samsung GX10, K20d and my K5II and the results are all as above.

The lens is still covered ( just ) by Sigmas 3 year extended warranty.

Any ideas as to what the problem could be before I send it off to Sigma.

Below are 2 photos to show what they are coming out like ( these were taken using shutter priority @ 1/125 )

Regards,

Chris.

** Update **

Hi all,

The K5 was returned to me today from SRS after a warranty repair at jp service solutions.

The included paperwork says ~ replaced mirror box - clean, check & test.

All seem to be working fine again. I don't know if it's just me but the auto focus seems a lot faster.

Regards,

Chris.
