Interesting comparison Amin, thanks for taking the time to do this...

I have an LX1, and have been taking a look at the GX100 as an upgrade.

One point, you mention that you had image stabilisation switched on for the tripod mounted shots. I'm not sure whether this is a typo, but you're supposed to switch OIS off on the LX1 if you're using a tripod. I doubt it would have made much difference to these tests though.

Also, I think the LX1 white balance was different to the GX100/G7 - also, I shoot entirely RAW, so any comparison of image quality would mean much less to me based on jpeg quality alone.

I'll be keeping my LX1 until the LX3 is released next month, and I have my fingers crossed that Panasonic/Leica can come up with a new zoom range starting at 24mm.

Kind Regards

Brian

greetings to all.
first of all a thanks to Amin for his very good job showing us this test..

i have orderer the gx-100 and still wait her to come in Greece.

i work in color most and i see in the samples something that i have notice before in other samples here in this site, before but was not sure if it was noise reduction or anything else.

at 400 iso the gx-100 (in color) has many (sharpening artifacts or a kind of noise reduction in it)?? the image is bad so as i see it.at least the g7 image looks better...

at 800 iso the same goes for the g7 ,where the gx-100 seems to give a softer maybe but better looking image with no smearing or sharpening of any type..i suppose this can be fix t.

You're right, I should have shut it off, probably on all three cameras. As you said though, I doubt it would have made a big difference with regard to noise amount/patterns. When I have a bit more time I'll repeat it with the IS off on all three.

Noi doubt the auto WB was way different on all three. I shoot almost exclusively RAW also, but thought I'd start with JPEG. I'll post RAW results later today or tomorrow at the latest.

Hopefully they will. Competition is always good!

How worse and aquarell-like the Panasonic/Leica is! But one
question: the cushion has a different color in GX100 vs.
Canon/Pany. The GX100 is more orange, the others more reddish. So
what's more accurate? Which lighting did you use?

Kind regards,
Andi

Andi, the lighting was supplied by indoor incandescent ceiling lights. The actual color in the room was somewhere in between the Canon and the GX color, though in sunlight the couch is as white as portrayed in the GX photos. Thanks for looking.

I think it comes down to taste. At ISO 400, the GX preserves slightly more of the pillow detail to my eye, though the G7 does a nice job of noise removal.

ISO 800 color was the only test where I significantly preferred the G7 results, which seemed less affected by noise reduction, with a finer noise pattern. At ISO 1600, the color files from both are looking pretty terrible, though the GX is still usable in B&W.

Amin

Hi Amin,

great question, I would have said Bibble or Lightzone... but I've just checked and neither package supports the GX100!

I would have to see either or both (Bibble and Ligthzone) support the GX100 before buying. I can't believe even the GR-D isn't yet supported!

I suppose Lightroom is the obvious choice - and I could always learn yet another RAW converter if it's worth the learning curve?

Kind Regards

Brian

I was planning to use Lightroom for both the Ricoh and the Leica
and to compare the results before and after Noise Ninja treatment
to the G7 images. Is there another RAW converter you'd like to see
used?

I'm not sure how well Lightroom compares to Bibble and Lightzone as I haven't used those, but I can tell you that the learning curve for Lightroom is minimal and there is a free 30-day trial. My RAW converter of choice, C1, doesn't support three of the cameras I shoot RAW with (Digilux 2, DLUX2, GX100), so I have been using Lightroom and find it to be very good as well.
