K-5 Focus Questions
Once you get into these hidden menus and start making alterations, you are on your own. I suspect that warranty would be out the window as well. It would be interesting to know how many cameras are returned that have been hacked, for want of a better word. I'm not surprised if Pentax have made it...

K-5 Focus Questions
When I run PK_Tether for the first time, I get a message 'Configuration file not found. Default configuration will be used.' When the program opens, everything is greyed out. Anyone have any ideas what settings need to be saved in the configuration file to get it to work with the K-5? BTW I'm ru...

Sorted it now - the camera needed a memory card installed for PK_Tether to recognise it! Thanks to everyone for the helpful suggestions, particularly Algi. Regards David

[quote:3496ace15f="Algernon"]If they are all on the + side you could enter Debug Mode Hi Algi, thanks for this suggestion, very helpful. I know how to enter Debug Mode on the K-x, but how is it done on the K-5? Is the same modset file that is used for all cameras? Regards David Ricehigh should...

All sorted now, thanks to Algi!! An adjustment of +100 in the Debug Mode, via PK_Tether and all is well! Most of my lenses now need little or no fine AF Adjustment and all are easily adjusted within the -10 to +10 AF Fine Adjustment option in the Menu. I suspect that my K-5 has been 'off' since I...

K-5 Focus Questions
Was the Sigma 150-500 out by much David? My DA*300 is +7 on the K30. Is there a thread on the best way to go about it. I used the line of AA batteries at 45 deg but wasn't certain if I should use the widest aperture during the test. Dave

Hi Dave, the 150-500 was out by as much as the rest; +10 on the old K-5. After the adjustment in debug mode (+100) it now focusses accurately without any fine adjustment in the normal K-5 menu. I used F8; this seems fine to carry out the tests. No need for any thread to give any detailed instru...

Thanks David. I have PK Tether already but what about the actual test, what did you focus on to do the check accurately? Last time I used a line of AA batteries at 45 deg to the camera and focused on the middle one.

Hi Dave I used a test chart, free in Amateur Photographer, placed square on to the camera, mounted the camera on a tripod and took three shots with differing AF Fine Adjustment settings. I then loaded these into Photoshop unaltered and compared them all at the same time in the horizontal tiled v...

I used a test chart which I set up at an angle to see if it was front or back focusing then tried different settings so I suppose it was similar. I think I will fine tune it now using your method. Joe, I wouldn't think it matters too much but I'm guessing just outside the minimum focusing distance ...

Out of interest are there any k-5 owners who have spot on focus with all their lenses. Since owning the mkii all my lenses are spot on razor sharp with no adjustments needing to be made, which means all my lenses are fine. Yet both my previous k-5 needed so much tweaking plus and minus I am begin...

My K5 is fine and much better with my 55 - 300 DA since the last update 1.14. (less hunting in high contrast skies) My 15mm Ltd has such a huge depth of field it's not going to be an issue. My 18- 135 DA WR has never been an issue. My attitude to cameras and lenses thus far is if they were out I...

can you say what distance from lens to chart please David It differed with each lens as each has different minimum focus distances and different magnification. With the 150-500 it was at a distance of approximately 10 feet. Regards David

Bill, regarding your post above, even with a 55-300 lens at F8, focus accuracy is absolutely critical. Even slightly off causes the images to be out of focus; when taking pictures of wild birds, the focus needs to be spot-on the bird's eye and even a bit off renders the image useless in my eyes. ...

Sorry, I was responding to the question asking how K5 owners got on. I get on fine and was stating that F8 is my starting point to avoid problems taking telephoto shots (not playing with lens settings). If owners had major problems then surely they should have used their warranties while they ha...
