The focusing errors in Olympus camera is not because of moving objects also 
not because of wrong focusing sensor used, I only use the center AF sensor. 
Don't know if you have read my E-3 story:

http://www.accura.com.hk/E3TEST/E3.htm

Similar problem happen to my latest E520. I never trust AF now even with the 
Canon, I just get burnt with the 5D II with Tamron 70-300 for stage shoot 
(all are still objects). I will only trust my eyes, if the camera does not 
provide a good focusing aid I will not use it. For your image, it seems not 
a good example, it doesn't have enough details to judge the focusing. I 
burnt mostly with 14-54 group photo indoor low light.

Complex sharpening only necessary when the image suffered from focus shift 
or vibration. Even with the E-1 I only need a light unsharp mask for the 
really focused images.

I'm also interested to see your conversion, here is an E-1 sample for you to 
play with:

http://www.accura.com.hk/temp/P3154214.ORF

I also had the 50/2, the lens seems focus much better than the others but 
11-22 suit my application much more. For macro I preferred to use 90/2 or 
135/4.5 for portrait, I use the 50-200.

For WB, I don't like to let it goes to far away, people also use filter to 
balance the color in film age. Of course I will not let an indoor warm shot 
trun into daylight or try to balance the magic hour shoots.

BTW, I don't see any RAW converter that will reduce the resolution of an 
image, not for the Capture One too.

Hi C.H.Ling,

I am quite happy with 14-54 AF performance. This summer I made a
photographic session to my best friend´s nephews. Even in the
swimming-pool the camera focused tack sharp under the water
http://www.myfourthirds.com/document.php?id=50368 but I never use three
AF points. This is a real nuisance. I wonder how E-3 copes with 11
points. Something I really like from E-3 and I haven´t seen it yet is
you can see in real time where the camera focusing with a red square in
the viewfinder. Due to E-1 limitations, you never can check accurate
focusing in the screen and when you upload the image in the computer,
you find out the camera focused in the wrong place. This only happens
when the subject is moving really fast. I suppose E-3 has solved this. I
can´t remember how many times you can´t enlarge the image in E-3 but you
can see if the image is perfectly focused. I also must say 14-54 optical
performance is not enough for me. As soon as Olympus has released their
prime lenses I´ll get rid of this lens. I need the quality of Zuiko
Digital 50/2. This lens is awesome.

You can send me an E-1 orf file and I´ll send it back to you processed
with my color profile and preferences. I am really interested to see if
you like it. ;) Something you won´t see is noise reduction or such
things like this. I like the pure image coming from the sensor, E-1
noise is film-like and this is something I really like.

I have created the icc profile for using it for daylight. I don´t like
white balancing the image. I love to see a blue cast if the day is
cloudy. So white point is fixed like film. If you white balance the
image, the message is lost. This cold and cool atmosphere is lost.

I used to spend too much time, sometimes several days processing tons of
pictures. Now all these properties are assigned to my images as they are
uploaded in my MAC. In one hour I can proccess 600 images with truly
stunning results. I don´t like Capture ONE, even the latest release
loses too much detail from my images.

5 Mp images need better sharpening algorithms because bayer pattern
loses too much detail when demosaicing algorithms are being applied. As
soon as the the same image becomes bigger like your 21 Mp image, you
have extra detail for the same subjet, so less sharpening is required.

I have seen these images. I prefer your E-3 image, honestly. Image
structure is far better than the other one. I am going to send you a
processed E-3 image with Raw Developer and you´ll see the results ;) I
am also going to send E-1 images taken with my Zuiko 50/2. You will see
the difference.

Warmest regards,

David Irisarri
