Sure. Initially seent Paul a pm since I don’t like google picking up ls threads in its search results, but what the heck. :)
The good:
IQ is really outstanding even at 800 ISO.
200+ISO RAW files have tremendous dynamic range as long as you don’t underexpose.
Files hold up extremly well to postprocessing and resizing.
Colors are very accurate and “true” if that makes any sense.
Auto whitebalance is quite good, especially with mixed lighting.
Full RGB Histogram, + you can zoom in and check values. Works very well.
No shutter lag noticeable.
Manual focus is easy, fast, and accurate since it has a zoom mode.
Gorgeous looking movies, probably because we all like shallow DOF..
The bad:
Mac Software (you need Sigma photo Pro to open the RAW files.) I hate its guts. It is slow, dumb, ugly, has no color management options, and it clogs up the RAM, just like word 07.
Rear LCD is no match for the quality of the files, in fact you can’t really trust it at all, especially with avaiable light.
No dust sealing. Why nobody thinks of this is beyond me. It’s quite sturdy though.
No top LCD for shutter speed etc. annoying.
I don’t really know what to say about speed, since I only have slower cards here at the moment. (Ultra II) With the camera set to single shot, it takes about 4 seconds to record the shot, and another 2 secs to save it to the card. After the initial 4 secs, you can take another shot. There is also a “burst” mode, which takes up to 3 images in a row, and then saves them to the card, might be practical in certain situations, but it’s very easy to fill up the buffer and the you’ll have to wait for it to clear..
It’s certainly fast enough for me, but then again I say that coming from manual leicas and an outdated Olympus E-1, so it might be slow as molasses compared to the canons (sic).
Movie mode is VERY interesting and works really well, but I’ve yet to try interpolating the file to DVpal size. The original file is only 340x something pixels, which might be enough if you just upload it to youtube et all.
I didn’t buy a proper finder, but I guess it would cure the all too common chimping syndrome. Which is really the only thing I don’t like about compact digitals.
Hope this helps!
Cheers
