I'v had a go at focus testing my K10D, mainly due to having bad eyes at either distance or close up, and wear bi-foculs to correct this. But i'm not convinced, even with wearing good glasses and having the diopter adjustment that i was focusing properly. I dont trust my own eyes.
So the test :
All taken @ ISO 280 / Centre Weighted
Focus point was on number 7 of the ruler, well as acurately as i could get the 7 inside the centre of the big circle.
No refocusing between shots to keep conistency
Tripod and remote cable - SMC-A 50mm - shot from widest f1.7 to f22, though i havent included any shots after f9.5 because the DOF gets quite deep and gets progressively harder to determine the exact focus point. So i have uploaded only shots from f1.7 - f9.5 inclusive.
Not really for test purposes , i set EV bracket for -1 / 0 / +1 , and what has me confused is the very first shot, ( f1.7 ) i checked the EXIF and EV bracket read 0 / +1 / +1 ...from then on, all shots in the EXIF read as they were supposed to I.E. -1 / 0 / +1 which is how i set it. That is, until f22 where the EXIF read -1 / -1 / 0 which is the complete reverse of the f1.7 shots. Weird ?
Would appreciate any comments
