Please help! I need to know if this is normal.

Please help! I need to know if this normal.


I just received a new Tokina AT-X 242 (24-200mm). With this new lens attached, every time I turn on the K10D, the first thing that comes up on LCD is the Shake Reduction menu. I thought that was odd since the Tokina AT-X 242 is new enough of a lens model that should pass the focal length information to K10D. Interestingly, if I try to choose a focal length by using the scroll ring, the screen disappears. Also, if I try to get back into the Shake Reduction menu, it is grayed out.

Grayed out SR menu indicates that the lens sent the focal length info to K10D. So, why is the SR menu coming up on LCD every time I turn the K10D on? Is this normal? I need to know so that I can return this lens if this is defective.

Thank you so much!

On your tokina lens, I think you have an aperture ring that ranges from 3.5 to 22. Does it have an A option that you can dial in? If you do (my feeling is no), then leave it there and you can use it like your kit lens.

When you turn on your camera, use the left and right buttons on the multidirectional pad to choose the focal length that matches the lens, in your case, 200mm.

There's other threads here that are similar to your situation. I'll see if I can re-edit my post and put the links up later on. But you can search here for manual focus lenses as a start.

Hope this helps in the meantime.

Hi Alvin,

Thanks for the reply. Yes the Tokina AT-X 242 has A on the aperature and I made sure it is set to A. Also, this lens is a zoom (24-200) with autofocus.

The SR menu only comes up when I first turn on the camera. And I can't even change the focal length on the SR menu when it comes up as if I tried to move with multidirectional pad, the menu disappears. When I try go back to the SR menu, it is grayed out (as if it did get the focal length info from the lens).

The issue I have is why is this menu coming up on LCD when I turn the camera on? And why is the menu grayed out after it mysteriously disappears.

hmmm. Seems to me that you might have dirty contacts on your lens or the camera. If you take of your lens and look at the back element, red dot up, you should see the contacts from the 5 to 6 o'clock positions. Just make sure that they are clean. On the camera, you should see them at the 6 to 7 o'clock positions. If you see dust, carefully blow it off with a rocket blower.

You can give them a very light rub with a soft clean rubber eraser too, just make sure not to rub so hard that you see the "crumbs".

Hope that helps.

It works fine with the 18-55 kit camera. So you are saying this SR Menu at startup is not normal behavior with 3rd party autofocus zoom lens. Correct?

Just to help you out a little. I have just tried all my 3rd party (Auto Focus) lenses and the SR menu never came up. The SR function is grayed out. I have Sigma and Tamron, but no Tokina.

I have also tried several Manual Focus Pentax-A and 3rd party lenses (also "A")and the SR menu popped up every time after startup.

I have not been able to replicate your problem, so I am guessing that it is not normal, but maybe someone else has a definitive answer to this question.

(I posted the same answer to your question at the other forum).

Forgot to add:

It makes no difference if the aperture ring is set to "A" with the Auto focus lenses. The camera still identifies it without a problem and the SP menu will not come up.

Thank you Alvin and HogRider. I guess I will have to send it back to Tokina.

HogRider, I appreciate you helping me out on both forums!
