Re: EXP-600 Iso comparison shots

Hi Gerd,

thanks a lot. These are exactly the pictures i was looking for. For me
ISO50 an ISO100 looks OK, ISO200 might be acceptable for small
print-outs but ISO400 looks really awfull.

How would others rate these pictures?
Is the noise in ISO200 and ISO400 normal/better/worse compared to
other cameras, that only squeezes 4 or 5MP on a 1,8 CCD ?

Re: EXP-600 Iso comparison shots

The noise reducing algoritms do get stronger at iso 200 and 400 as the finer details in the picture are more blurry compared to iso 50. Still, I think iso 200 is both acceptable and usable, while iso 50 looks beautiful (for a consumer cam). Comparing with other digital cameras I don't think noise is any worse here.

Interestingly, the WB is not similar on the four pictures. Iso 100 and 200 are a little warmer than iso 50 and 400.

I've just ordered a EX P-600 myself to have a camera that I always can carry with me. I think I'll do most of the shooting at 3 mp and not 6 mp to save file space.

Re: EXP-600 Iso comparison shots

Thanks for posting the comparative ISO shots.

Would it be possible to see the same type of comparison done in an indoor setting as well? Also, an indoor Portrait comparison group would be appreciated if you have the time.

It's clear that outdoors, ISO 50 and ISO 100 are quite good. Even ISO 200 is pretty good. One cannot expect ISO 400 shots will be great, as it isn't in other cameras as either. Even the new Leica digital is really good at its ISO 50 setting. So how can you expect this camera to be different?

Re: EXP-600 Iso comparison shots

Georg,
Thank's for posting the ISO variations.
They are very informative (it would be nice to see an indoor series as well).

From the ISO pictures you provided this is my impression (when viewed on screen in 100%):
50 ISO: Very good looking, noise almost invisible.
100 ISO: Noise noticable.
200 ISO: Noise very visible.
400 ISO: Very much noise, ugly.

(Just my personal impression based on provided images. I don't know how it compares with other camera's.)

Unfortunately most reviews and galleries mainly post pictures in 50 ISO, so it's dificult to find any reference material for other populair digicams.

Agreed

Similar to the impression I got from psalm27. But iso 400 could have been left out. And I'm not very happy with iso 200 either. The noise reduction reduced the detail of the grass, and causes visible sports on the roofs.
And there's a shift to more red in the middle two pictures...?

Re: EXP-600 Iso and whitebalance

Georg,

The 4 ISO variation pictures were taken with about half a minute between each picture. The sky looks unclouded.

The whitebalance in the 4 pictures is quite different, in the 100 and 200 ISO images there's much less blue in them.

As the sky looks unclouded, I assume the difference in whitebalance is not related to cloud/sunlight variations.
In which case it looks like the EX-P600 has a whitebalance problem.

Can you confirm this ?

I noticed this too. A little strange. Otherwise I am very impressed with the images from this camera so far. Detail is good and they sharpen nicely. ISO 50 shows very little noise.
