Did anybody try to do Focus Scale Calibration on Irix 15? This is one of interesting feature of this lens, but can not find any info if anybody really didi this.
I am doing this based on manual, but if i moving with internal calibration ring, i can see no change in focus on live view, doing at F2.8. It seems like this ring is doing nothing. It does not matter at what position of this ring i will re-tighten screw on internal focus ring.
Info from manual:
To calibrate the focus ring:
1.
Remove the calibration window cover by unscrewing the T6
Torx screw and sliding the cover outward.
2.
Set the focusing ring at the infinity position and rotate the
focus lock ring to the locked position. The internal calibration
ring and flat head locking screw should be visible.
3.
Using a flat head screwdriver, loosen the screw on the cali
-
bration ring. Be careful not to allow the screws to fall into the
lens housing. A screwdriver with a magnetic tip is recommen
-
ded.
4.
Using your camera’s Live View and LCD zoom, rotate the cali
-
bration ring to focus carefully on a distant subject (farther away
than 50m/164ft).
5.
Lock the calibration ring by re-tightening the screw and re
-
place the calibration window cover

Hi Weevil, yes i am sure. I also did another test to be sure. It this test i did focus via live view on left side of the picture and take a photo. Then i did same with right side of the picture. If i compare both photos, much sharper photo is on second picture (right side of the frame).

I have tired bulb mode with 10s. After 10s of exposure, i waitd another ten for noise reduction. I did not see counting down od this time, strange. After that time, LCD screen does not work, only gps led was lighting. Turning off and on camera does not help, led of gps was still lighting if camera was off. After removing the battery, camera was working again. Strange. I can not recrate this issue again.
