Pentax 100mm macro lens stopped responding

nezih · 02-06-2011, 01:29 AM

My non-waterproof pentax 100 mm 2.8 lens suddenly stopped responding without any reason. F keeps on blinking when I adjust the lens on my K20D.
Need help.

If your lens has an aperture ring, is it set to "A"?

My money is also on needing to set it to "A" on the aperture ring

Hello,

Without seeing it, it's hard to say. I would contact Pentax directly to see about getting it serviced.

Or just set it to the "A" setting on the lens as I would bet 99.9% of the time that's the reason you'll see the "F" blinking on your LCD.

Thank you so much folks for the concern and advice, I thought I'd set it to A, but it did not work because I forgot to push the black button. Sily me!
Now I feel like I bought it anew!
Thank you all!
