Hello, You may have already had this question on the forum in the past so please forgive me for reposting the enquiry.

Is it possible to use an old manual lens on a K10D and obtain the correct exposure using a lens such as a Pentax-M or M42 mount lens. Which obviously don't have any electronic contacts.

If you can, then please let me know what I need to do to undertake such action.

Best Regards, Paul

Thanks for the suggestion of scrapping off the paint the image helped me easily understand what I needed to do. I have just done this and they work as I originally expected them to work. So thank you very much indeed.

Thank you for both of your responses, the extension rings have six contacts and are made by Jessops. As you suggest I will scrape some paint off both sides of each extension rings.

Is it possible to add these extension rings to a macro lens to get even closer? or should they only be used with standard fixed lenses?

Another question the set contain 3 extension rings (13, 21 & 31) is each one for a set lens or magnification?

Your help and advice would be very gratefully received.

Best Regards,

Paul

Hello all,

I have recently bought a set of PK-A extension rings to use on my Pentax K10D.

I have mounted the PK-A extension tubes on my camera then attached my PK-A lens to the front.

When I switch on the camera I get a message asking me to set the correct focal length. So I set it accordingly, then when I look at the LCD display on top of the camera the shutter speed / aperture settings flash. The camera does not allow me to manually set an aperture all I get is 'F___' and when I look through the view finder it is very dark (probably because I am unable to set the aperture).

Has anyone experienced these symptoms? and more importantly is there a cure so that I can use my Pentax FA-J and DA lenses with these extension rings on my Pentax K10D??

Best Regards,

Paul

Hello,

I hope you all had a good Christmas and Boxing day.

I am looking for a reasonably priced Flash Gun that is compatible with the K10D. I currently have the Pentax AF-360FGZ flash gun, but i am now looking for a flash gun with both bounce and Swivel action.

My budget is £200 MAX.

I have seen the following advertised on-line and wondered if members of this site could advise me or pro/cons of their experience with the following flash guns.

Sigma EF160
Metz 44
Metz 50

I don't use flash often, just once or twice a year, so getting an all singing all dancing flash would probably be a waste of time.

Wow that would have been a Christmas Cracker. Well I hope you enjoy using yours I'm not jealous well maybe a little. But I have put the money towards a secondhand Sigma Macro ring flash so I couldn't have afforded both.

I missed out on the Amazon offer (Doh), how much did they reduce the lens down to?

Thanks for your feedback, I think I will dispose of this particular lens, and will get back to using my Tamron 500mm Mirror lens for Wildlife photography.

Whenever I have used this 'affected' lens the focusing has never been spot on and all the images have been a little bit blurred (e.g. not sharp) now I know why.

I did keep this lens along with my other Sigma 70-210 manual focus lens in a plastic box, I got that lens for £10 so I think I will get rid of both lenses. see how i get on with the 500mm Mirror lens and then make a decision early next year.

Thanks again for your help, comments and advice.

Best regards,

Hello All,

DoctorJeff - I have done what you advised and can confirm the following.

The sizes of the dots are very minute (I say dot's in inverted comma's) because when I say dot's I mean hundreds if not thousands of the little blighter's.

When I look from the back of the lens and close the iris (aperture) the affected element is beyond the aperture mechanism and when I look through the front of the lens and rotate the focusing ring the affected element moves forward / backwards as and when I rotate the focusing ring. So the affected lens/element appears to be part of the focusing section of the lens.

Here is the best image I could take of the said fault, as I said previously I have never seen anything like this before!
