Your remarks are welcome!

I enjoyed going through your Flickr album, photos from both cameras look good to me.

Joe

Thank you very much for your feedback

I don't know; which was more accurate? Boosting saturation in post is very easy if that is what you want to do. I usually find I can boost saturation about +3 without the image looking phony with my EM-1's. Backlit, depending, I may boost saturation more if there is significant shadowing.

Both photos look great, but the Quattro wins if you like more detail.

I wonder if the comparison of the cameras at iso 1600 and picturing a low lightning scene is also in favor of the Sigma.

Jozef.

Saturation is one factor among many
Here I apply a minimum of retouching to remain fair between each camera.
The Sigma is by default much more saturated.

For me, the Sigma completely collapses at 1600 ISO

Yep, Lumix wins in low light, I think.  Won't be able to see the Lumix photo for another 4 weeks, however.

The main difference I see is in brightness of reds.  I bet with some simple editing you could get your GX7 pictures to look a lot more like the Sigma camera.

Yes, iso1600 looks horrible from a Sigma Foveon sensor, it's IQ is even worse than I thought.

Thanks for posting.

Jozef.

Of course, it is still possible to interact on the render.
By the way, it is not always easy to modify a color, without modifying the whites.

And what about ISO 6400
Thanks!

Not sure I understand

Check the EXIF date on the Lumix shot above.

Ok, the little jump into the future
