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
