Testing the E10 - a favor, please.

Curious, but very possibly just the difference in cameras as they were aligned during assembly.

I appreciate you input - since I have started this quest the news has spread considerably and I am finding more and more E10 owners that have had problems with manual focus and just went to AF but are now re examining the problem and calling Olympus to account.

I'm just adding this because I found it to be a contributor to my
initial focal woes. It's obvious, but on the 9mm setting to see how
difficult it can be to focus, depending on light, pattern of
object, just focus on something and while looking thru the
viewfinder, walk forward and backward. One's got to walk a long way
before things get oof. Up, up and away.

That is the reason for doing any testing at 36mm and f2.4(if you are printing) as the depth of field covers up many focus errors at shorter focal lenghts.

Hi Ed

I first had a long correspondence with Oly UK about scales etc. but we came to no very clear conclusion.

In the end I simply sent them two jpg files - of a ruler shot at 45 degrees - one was focused at 4" and the other (manual) was also focused at 4" but was actually in focus at 6" - they immediately understood the problem, took the camera in and fixed it free of charge.

Possibly a simpler solution?

kind regards

Sorry, I misread your mention of scales - thought you were referring to the LCD distance scale.

You have done the ultimate test when you shoot a ruler (or other graduated target) at 45 (can be some less) degrees to the camera/subject line, but it is really hard to explain this in words so the LCD distance movement test was substituted.

Sincerely,

Ed O

Did both the visual test as you specified and the photo test using the 24" ruler at 45 deg.

In both cases the results are the same: there is no discernible difference between the manual focus and the auto.
Camera: E-10
Serial 1064xxx
Firmware: 1.20 (ancient)
Guess I should hold on to this baby... ; )

At f 2.4, fl 36 mm, distance 2 feet?
To force f 2.4 Aperture or Manual mode can be used.

I have used Apertue Priority to get full aperture.

Thanks for the additional info, Alex. As for your final question, "Ed O" is running this survey; guess we'll have to wait for his analysis. There have been a few good cameras noted, as I remember. Certainly, Oly must have designed the camera dimensions correctly and had some good ones fabricated. I've heard in this thread the problem is the ground glass screen is CEMENTED in place and I guess some workers used too much cement and lifted the screen from its intended mounting surface. According to my calculations, a discrepancy of 2 inches at 48 inches (with focal length of 36 mm) corresponds to about 0.002 inches displacement of the ground glass from its design location. IF the Oly design didn't allow enough (or any)relief for the glue, that sounds like a likely source of the problem.

Either you got a good one by chance, or a unit manufactured after the problem was corrected.

Russ,
It will be very interesting to know the results of the survey.

Somehow I feel that the problem must not be related to the focusing screen, a discrepancy of .002 inches is probably well within most camera tolerances. I think it is more likely that the problem is to be found in the placement of the sensor, after all is just a component solderd to a PCB with all the consequent tolerances. But again this is only speculation.
