Ricoh GX100 and Kodak P880

Hi all,

here is a small comparison between Kodak P880 (24-140mm equiv., 8MP) and Ricoh GX100 (24-72mm equiv., 10MP). While the P880 is of my own, GX100 belongs to my colleague (so I have had it for testing for a very short period only).

All the images below were taken in M mode, JPG's at their best quality, full size and default all the other settings. P880 images at ISO50, GX100 at ISO80, and AF set on both cameras to infinity (which I use for timelapsing, so I was concerned namely about this focus mode). All images were taken from a solid tripod and with 2 sec shutter delay.

The first two images show fields of view of both cameras at their wide end (24mm), apertures set to F/3.2:

GX100:

The P880 has slightly (marginally) larger field of view, but also more significant vignetting at corners.

Next four images show crops from these. First two images are crops of the central area:

P880 crop - center:

GX100 crop - center:

Next two images show crops from the left sides of the original images:

P880 crop - left:

GX100 crop - left:

All the crops show somewhat different area because of different sensor size.

Comparing either the crops or the full size images shows that GX100 is noticeably sharper, and this was true for the entire range of apertures available on both cameras.

Next images show both cameras set to 72mm (F/5). First, the full downscaled images:

And center crops from these:

Even here GX100 performs somewhat better as compared to P880 as regards sharpness, but it seems to me that P880 has a slightly better contrast at this focal range.

I'm aware that I should have taken the same tests using a regular autofocus, or should have taken these in RAW format, but I was in time press when doing this... Also, I can't be quite sure that my P880 is not a bit "out of focus"...

I hope that this small comparison shows to those of us who own P880 and need to replace it one day, that there is more than excellent replacement available on the market...

My impressions from the time-lapse test with GX100 and R6 in couple of days, after I process all the images

Regards, Martin
