Frustrated by intermittent focusing.......
Over time my K10D focus drifted quite a bit, especially with the 50mm f1.4. In the lens it was almost unuseable with both that or the DA* 55mm f1.4. I downloaded the Russian firmware that allows you to alter the focus and that made such a difference it was untrue .. like having a new camera again. ...

Frustrated by intermittent focusing.......
I too now have a back focussing problem with my K20 and like the OP have a DS with no issues at all. The K20 is doing it with all lenses and the inbuilt calibration isn't sufficient to correct it. If I focus manually using a tripod and then switch to AF you can see the focussing ring move. I was ...

I found a downloadable file on the other Pentax forum which did the trick. A global adjustment of +240 and no individual lens adjustments has brought back happiness and bliss! :)

K Mount teleconverter on K-x?
Hi folks, can anyone advise me please? I know it is possible to use K mount lenses on the K-x, but I assume that means I will either have to manually focus or set the aperture (or both). But, I have my eye on a ridiculously cheap Vivitar K fit 2x Teleconverter, and I am wondering if that will wo...

K Mount teleconverter on K-x?
If your lenses have no saperture ring you won't have any control of aperture with a K fit TC. IIRC you'll be left with both lenses wide open with the TC. You'll probably find cropping the image a better solution for the moment (which needn't cost anything). KA type TCs allow the camera to adjust the...

my thoughts on the k5 and pentax compact digital cameras
I've been browsing lots of websites lately with lots of pentax users dumping on the k5 and compacts.I purchased the k5 and gave it a test drive and it did'nt take long to realize this is one of the best cameras I bought.Compared to my nikon d300 which was my favourite camera and canon 7d I give the ...

my thoughts on the k5 and pentax compact digital cameras
I was thinking about the focus issues. The stain thing is a manufacturing fault with some units, covered by the warranty in all cases, rather than a shortcoming of the k-5 compared to other makes of camera.

M42 adapter for the K5
Sounds like you need to take your K-5 back to the Dealer.

Sounds like you need to take your K-5 back to the Dealer. If there was a problem with the camera then lenses wouldn't fit either.

M42 adapter for the K5
How about using the 13mm form a set of macro tubes, I know it will shorten your focal length but it means you can use the lens. Extension tubes do not chnage the focal length, they allow you to focus closer :wink:

M42 adapter for the K5
Are you sure it's not just the tripod foot that's in the way? That should come off as (in Russian unfortunately) I think it will work with that removed, if not the extension tube should work, because you only use these lenses within 5M and losing infinity focus won't be a problem. That's ...

That lens does have a reputation for slow focus.

yes, i was very, very shocked! The 28-70 was quick sharp, so this is a bit of a step back in that respect, mind you, my Pentax K20 with 16-45 was more than three times as fast also!

Must be absolutely gutting to come back to something which is: "NOT a professionals camera" and "isnt really aimed at the pro market" and has such problems as: "the metering with pentax is WAY off" and which: "doesnt cope with low light or high light to well at all IMHO" and...

Who are you quoting there Robbie? I can't understand where you're coming from. You have to go back a while to when Feebs decided to change from Pentax to a Nikon D700

Who are you quoting there Robbie? I can't understand where you're coming from. All I will say is that they are all accurate quotes (in that they were made on this forum, not that their content is correct). and as said by feeb the only reason for the change back is the k5 has greatly improved over th...
