I earlier had the problem of front focus on my camera, after getting it repaired, I tried a few focus test. I get mixed results on this, so anyone with more experience claim about the focus issues here?
Test 1
This is the test chart from http://www.focustestchart.com/chart.htm. Here I feel that none of the lines are properly in focus. The pink box shows where I tried to focus. Is this because of low light condition.
ExposureTime – 1/200 seconds
FNumber – 1.80
ExposureProgram – Aperture priority
ISOSpeedRatings – 400
Test 2
In this second test I just cranked up a Corel vector graphic and tried to focus on the monitor screen. This looks good to me and in focus.
ExposureTime – 1/25 seconds
FNumber – 1.80
ExposureProgram – Aperture priority
ISOSpeedRatings – 100
Test 3 (Worst)
This last test blows me away, I try to focus on the corner and this shows a heavy front focus. Is this because of low light? Is this because the actual area where the camera focus from is slightly shifted? I just used the center AF point for all the three tests.
ExposureTime – 1/15 seconds
FNumber – 1.80
ExposureProgram – Aperture priority
ISOSpeedRatings – 100
