s90 is a nice camera...but limited...and higher ISO seems a bit noisy..I am still using the classic F30 Fuji for that type of camera......of the PS bodies on the market today the new Oly XZ-1 seems by far the best w/regard to high ISO noise....see this site:
http://www.dpreview.com/reviews/OlympusXZ1/page11.asp
and compare it to the 7D, D7000, and Sony a55, G3, Pentax K5 up to 400 ISO....and let me know what you think.... compare it to the s95, or other high end PS cameras...and there is no comparison.
....it also has a f1.8 lens slightly faster than the Canon and is the only one that seems to hold it's own against both APS and 4/3 sensors up to about 400 ISO at present and would be on my short list if I was getting a PS today.
I have a G1, and a G3 on preorder now. I shoot with Canon 7D and 5D bodies. I love the G1...but hate the lag as far as response time/shutter lag. The output quality at 100 ISO even of the G1 rivals the output of my 5D. At high ISO, the 5D IQ smokes the G1. I am hoping the faster refresh rate and improvements on the G3 will make it a more usable camera.
Daughter recently took an interest in photography...so passed the G1 to her along with a bunch of legacy fast Nikon mt lenses remaining from my Nikon days prior to Canon.
Currently her kit contains:
180mm f2.5 Tammy....very sharp MF lens w/aperture ring....think similar to 360mm f2.8 (but faster) for a FF.....or equivalent to a $3000+ lens for other bodies....
add the 2x matched multiplier....she has the equivalent of a 750mm f5.0....try buying or carrying that around for FF.
Still had the 85mm f1.8 Nikkor..... makes that a 170mm f1.8....close to the 200mm 2.0 L Canon...go price that baby...one of the few lenses I still lust after..
A 50mm FD Canon f1.8 gives her a nice 100mm effective focal length fast portrait lens....also with manual apertures if you want to stop it down...
The 55mm Micro Nikkor f2.8 becomes a 110mm Micro.....etc...all the MF lenses focus remarkably well on the EVF of the G1....and they gain up in low light still making the quite usable at smaller apertures if you decide you don't want to use the speed of these lenses to the max.
While the kit 14-45mm is still the only wide she has...at least it is also IS...and pretty darn nice for a kit lens....and she has a killer system with that bunch of lenses I hadn't been using for years....and the ability to use any of my EOS lenses, as well with a few more adaptors at about $20 each...a few more Nikkors like the 20mm 2.8 I still haven't shown her are still beating around here too....
I did tell her ....lose interest in photography...and it all still belongs to me....keep up the interest...and she can consider the stuff hers....
Time will tell on the G3.....IF I ever get it to try...Panasonic is not proving terribly good at delivering the product yet.
