Good day to you. Sorry for my late reply. The EP-2 will be available in this weekend. Kindly visit your nearest retailer shop.
above is the reply from olympus.. rclxms.gif

ahhh.david..u know i have been poisoned by E-P2's photos taken by some users from taiwan..the colour produce is really bright, clear and rich!  drool.gif however GF1's colour not that pretty and a bit dark but still clear...

i really...  icon_question.gif

i read one of the comment from them, "if i wan to take photos under sun, or enough lighting, i will bring my e-p1...but if i wan shoot the foto under darker environment, GF1 is  better and faster to focus...both camera give me different experience and fun in photography " so jealous they have both! drool.gif  drool.gif

some photos taken by E-P2:

thats mean by tomorrow Friday or Saturday the retail shop should have E-P2 rclxms.gif

Actually EP-1/2 is not better than GF-1 and vice versa. It is just how the camera designers intend to expose a picture. They may have various reasons or intentions of doing so. You can see its clearly that they both use different image processors to begin with. Its just more of a preference or taste. I remember in the past where Canon launches the 400D DSLR camera. It underexposes a lot too but people fail to understand why this is the case and blamed it on the camera.

As usual, I will not say whether the EP-1/2 or the GF-1 is better. Since both uses the same library of lenses, it doesn't matter. I'm more interested to explore the noise reduction/filtering strategies from both manufacturers. I hope Wrotniak has written an article about it. Let me check if there's any.

I had the Evolt E-30 (probably irrelevant to speak here) and the noise performance is... well I would say.... tricky...

Actually we can overcome the supposedly 'underexposure' of Panasonic cameras. It require some experience in identifying the scene that we're capturing. For example, Panasonic camera usually underexpose by increasing the shutter speed whenever it senses a large body of white colored surface. And also brighter colored backgrounds. So under these situations, you can always increase the exposure compensation by +1/3 to +2/3.

Also Panasonic uses the shading compensation (I forgot the name) to increase dynamic range for both highlights and shadows. As a result, exposure is averaged and if there are white background it will underexpose to prevent overexposure of white. You can try turning it off to see if it helps. For Panasonic users, I think it is beneficial to use RAW because it reveals more potential. With RAW it doesn't matter if you underexposure or overexpose because you still have headroom to recover these areas.

For Olympus, users may not see a need to use RAW because the JPEG engine is so good that using RAW will not present more headroom for PP. So yes, Panasonic users can workaround by tweaking the Film Modes to mimic the 'Olympus Color'. One forumer shared with before that there's profile to do that. However, keep in mind that color tweaking on body can only do so much. It may not work for certain situations. For example if you tweak the color to be more warm, if you are taking a portrait... the human skin may become ridiculously reddish. If you use RAW or use a natural color profile... you can still use PP to tweak to your hearts content.

i think most of the review saying that e-p1 produce less noise in higher iso and more saturated colour.. however gf1 produce softer image at higher iso which lead to less sharp of the image.. so i am also wondering who is the winner in this??
*
Its very obvious hehehehehe... Actually EP-1 has a very good advantage. It is using the latest TruePic V. GF-1's photos are soft because it is using a stronger noise filtering.

I think the EP-1 is even better than my E-30 in terms of noise management.

I'd prefer lower noise level even the quality is lower a bit.

That depends on a lot of things. First in order to achieve a noise-free image or a low noise image, we need to perform noise filtering and AA. We know for a fact that image sensors (especially 4/3 ones at this development stage) is noisy depending on its design. The problem is noise filtering reduces detail. So the strategy is to either implement a strong filter at the expense of reduced detail and softness or a weak filter for preserving more detail and sharpness.

I prefer to see more detail and have higher quality at the expense of some noise. Why? Because you can't see it on a normal picture or when you print it out even at large sizes. You will only see it when you view it 1:1 or pixel peep which is pointless in my opinion.

QUOTE(Hico @ Dec 10 2009, 11:30 PM)
is the noise filtering can be adjusted so that it can produce sharper image?
*
I have heard of people disabling the noise filtering totally in order to enjoy more details. Your suggestion is quite accurate in the sense that using a weaker noise filtering setting reduces the blurring as a result of filtering itself (but at the expense of more noise). However, Wrotniak's articles have mentioned that you cannot totally switch off noise filtering although you choose the OFF setting. Some degree of filtering is performed. Unless you shoot RAW to avoid noise filtering and gradation settings. Don't use Olympus Master to develop the RAW but use ACR to do it. Then use your favorite noise filtering software like Imagenomic or Noise Ninja to do the job. You'll get better results. Of course... that depends on the level of commitment you're willing to give just to have good photos.

Also we know for a fact that the Gradation settings for JPEG causes more noise even on low ISO. Select Normal Gradation instead of Auto because Auto will bring out more shadow noise. And you cannot totally disable it because you can't.

Which small bounce flash do you guys use for your E-P1/GF-1/E-P2?

I am looking for something lightweight but can also tilt and/or swivel, mainly for fill-in light

A few models which looks pretty cool on the E-P1.
- Metz 20-C2
- Metz 36-C2/C4
- Oly 36R
- Panasonic FL220

Thanks in advance

I would recommend the Olympus FL36R because it fits right into your requirements. The rest does offer tilt and swivel but are not TTL-capable. The Panny is usually a little expensive for the kind of performance it provides. Metz does have a 36-version with TTL but don't offer LCD display so you need to do settings on the camera which is troublesome while its higher end model is too big size.

below is some comparison photos taken by e-p1 and gf1.. but of cos u can tweak gf1 to get more vibrant colour.. yet i still think e-p1 produce hotter colour and gf1 produce cooler tone.. its really depend on ppl's taste..
sometime i do prefer vibrant colour especially shooting flowers etc but sometime i prefer nature colour when shoot people..so u can decide yourself..

Olympus camera's straight out JPEGs have always been colorful and punchy. Thats what a lot of people have been saying about. Everything looks tweaked and doesn't need much post production.

Thanks for ur opinion bro. smile.gif Hows work?

Btw i heard tat EP-1 AF is around 1 sec and GF-1 AF is 0.3 sec is tis true? how much it will affect my photo taking?
*
It shouldn't distract your photo taking process too much unless you're working with a dynamic subject or at a rapidly changing environment like an event. Otherwise, things should be well under control. The EP-1 does have one problem initially and that is the C-AF. However, recent updates have improved it significantly so it is not an issue anymore.

ya..while i test e-p1, the lens like in, out then in to focus to the object.. but GF1 will like in or out one step only then focus oledi.. so cannot deny GF1 is faster in focus.. but E-P1 is not that bad too.. but for taking action photos or moving object, don think it will be suitable..  tongue.gif
*
Yeah that's because the EP-1 prefers to focus out and then focus back in. Sounds to me it cannot AF in small increments or a weakness in the contrast based AF algorithm. If you look at Imager AF on it's DSLR with CDAF lens, the same thing happens.

GF-1 I heard it performs continuous AF as you move around so by the time you focus, it's already pretty near. But still it's contrast AF is the most responsive I have ever seen.

Hmm, why is Canon "underdeclaring" their ISO then?

Talking about ISO performance, I guess GF1 v1.2 Firmware really made some improvement on that? Can't really spot any obvious difference compare to shooting in Raw
*
I think this is expected and very typical. Nowadays, it is almost a reality that manufacturers rate their ISOs differently from the other. Remember we can get the equivalent of ISO100 from ISO200 but reducing its exposure? I can say there's more to that. Almost all Canon cameras have lower intended ISO values for every ISO stop.

Maybe it is a good strategy for image quality preservation but with some small loss of shutter speed.

Aiya.. built-in flash you like meh? tongue.gif Maybe for emergency situations lar... but flash gun is more versatile.

But I wonder if this new model has wireless TTL capability. Cause for Olympus, you need a built-in as primary flash.

Seems the E-P1L support wireless TTL
"NEW POP-UP FLASH.
The E-PL1 is the first camera in the Olympus PEN series with a built-in pop-up flash that makes it easy to illuminate low-light subjects, reduce red eye, and fill in dark areas. The camera is also compatible with a range of optional external flashes including the Olympus FL-36R and FL-50R that can be controlled wirelessly by the E-PL1, so you can dynamically control lighting."
