And the winner is.. Me! :smile: And the loser is those who like really rigorous tests, I suck at those* Stop me if you've heard this one.. In the last month I've tried to come to grips with my camera future. My K-7 is getting less use as the convenience of a compact kit sinks in. Size matters to me, like it does to many of you, and while the K-7 is truly amazing for the amount of features per cubic inch, I'm not really using a lot of them. In a semi-desperate act to make the K-7 more to my liking, I swapped three very good lenses for their new weather-sealed 18-135 with internal motor. It does make for a compact set (I still have their WR 50-200) so it's ready to challenge the G1 in serious tests. But it's worse than that, as I just picked up a GH1 body (yes, one of the last ever!); it arrived a day after the 18-135 to compete for my time. Two weeks earlier, my big quest for small gear also netted a 40-150 m.Zuiko to challenge the Lumix 45-200. Somebody stop me!! Anyway - I set up the tripod tonight and shot this tortuous scene: I shot iso800 at 60mm (80mm on K-7) and at 150 (200mm on Pentax w/50-200 lens) and examined the highlights, shadows, wall texture, text on the light socket.. you name it. I set all three cameras the same - well I tried* but I never can - and adjusted shutter speed to meter the same result. All are RAW shots, and Picasa did the conversions with no intervention. The results were no great surprise (images can be seen at my Piacasa site). Other than tungsten WB working best on the K-7 they all did fine work, and both G1 and GH1 look equally good with either tele zoom. Test freaks can look them over & pick them apart; nobody wins when you point out the obvious but have at it. At some brighter luminance levels the G1 appears to lose detail relative to the other two even at lower iso values, but a bit more targeted PP could take care of that. All my work was done to the entire image. I also shot a single iso2500 image with each setup (G1/45-200, GH1/40-150, K-7/50-200). All three cameras are stressed (banding + some color shift), and all look very good with 2-3 minutes work in Elements 9. I cropped and re-scaled them to look as similar as possible (see the last 3 shots in the picasa folder). Maybe I'll run some outdoor shots this wet weekend.. or maybe not. partial list of what I did wrong starts here.. G1 and K-7 shots were 3:2 but new GH1 still set to 4:3 Lumix 45-200 shots have OIS enabled - on a tripod! K-7 SR is also enabled - on a tripod!
