I give up. I bought my G2 8 weeks ago. After extensive testing, I've concluded this camera is not ready for prime time.
1. I took 179 photographs on a long trip. I've studied them extensively.
Of 21 close focus photos (by my definition, the subject was up to 3 meters away), 10 actually focused at least double the actual distance to subject. 3 focused at 66M.
Of 72 medium focus photos (subject is 3.1 to 15 meters by my definition), 40 either focused less than half, or more than double, the actual distance to subject. Several group shots were out of focus.
Of 86 long focus photos (subject over 15 meters away by my definition), 38 focused at less than half of actual distance. Especially troubling were the 10 that focused at 2 to 5 meters.
2. Since examining those photos, I've done extensive testing, probably 200 test shots in all. The G2 autofocus is all over the map and cannot be trusted for precision work.
3. I thought Pan Focus would be the easy solution since the manual implies that focus is fixed. Well, maybe it is, but the first in any Pan Focus series shows EXIF distance of 1.39 meters, the remaining show 66 meters. Comparison prints show the 1.39 meter photo is probably focused at the same point as the 66 meter photographs. So here is a case (the first photo in the series) where the EXIF distance data created by the G2 appears to be bogus.
4. Well, I thought, the solution is to manually focus. I just took a shot manually focused at 5 meters. The EXIF distance data shows 4.96 meters. So far, so good. Yet the print shows absolutely clearly that the G2 actually focused at 2 meters. Everyting 5 meters away is hopelessly blurred.
Now, before I'm flamed as not knowing what I'm talking about, I've been taking photographs for 45 years, have owned probably 40 cameras over that time of several brands and formats, and have extensively studied the technical aspects of photography over that time. I'm partial to no brand. And I know about contolled testing.
And I've read the G2 manual extensively. I know how to run the camera. I know all about pushing the shutter down part way and waiting for the green light or square to come on, then completing the exposure. And I know the importance of putting the crosshairs on the high contrast and important part of the subject. (Although for the life of me, I cannot understand why the G2 was designed to properly focus on vertical lines, but not horizontal lines.)
One frustration lies in the fact that the G2 gives little meaningful in-camera feedback as to actual focused distance. The zoom lever doesn't yield much unless the photograph is grossly out of focus. So I know little about actual focus distance until the image is transfered to the computer.
I'm also aware that the large DOF of a 7 to 21 mm lens covers up most focus problems. That's livable provided the max print size is small. But I want more than that. To me, no camera is worth it's salt unless ALL images are capable of 13 by 19 inch prints, (where the stars are aligned and the photograph is worthy of hanging on the wall.)
The G2 would be capable if it focused properly. The 4 megs, the color handling, and the wonderful lens are enough. But The G2 is the first camera I've owned which had autofocus problems. I can't believe that given the G2's great lens, color handling, and battery life, that Canon would screw up the autofocus so badly.
I simply cannot trust the camera. To ensure the photograph is properly focused, I have to use one of my other cameras. The G2 just doesn't hack it.
I'm calling Canon today.
