dantheman Posted January 20, 2017 Share Posted January 20, 2017 I have just received my g80 and I also have a gx85 that I used the past months, when I did some test shoots with the g80 to compare with my g85 to see if colors matched I noticed that my g80 footage seemed to be on the soft side, almost slightly out of focus, so I pointed both camera's on a resolution chart where there is a clear difference in HD, in 4K they almost look the same but still, also there I see a very slight difference in favor of the gx85. Are there any g80 users that also have a gx85 that have seen the same problem? Quote Link to comment Share on other sites More sharing options...
tupp Posted January 20, 2017 Share Posted January 20, 2017 It appears that the GX80 has some artificial sharpening, judging from the halo around some of the lines/numerals on its chart. By the way, did you use the same lens with each camera? Quote Link to comment Share on other sites More sharing options...
Super Members Mattias Burling Posted January 20, 2017 Super Members Share Posted January 20, 2017 This is good news. I was afraid the g80 would have the same look as my gx80 and not like the imo nicer g7. Thinking about buying one as a b-cam to my Olympus when the gh5 makes the prices plummet.

dantheman Posted January 20, 2017 Author Share Posted January 20, 2017 34 minutes ago, tupp said: By the way, did you use the same lens with each camera? Yes, used a 12-35mm f2.8 and both camera's had exactly the same settings and shot in standard with everything at zero. 1080p on my gx85 doesn't look so nice as there is lots of aliasing on wide shots which might explain the artificial sharpening that is applied. My gh4 however has the same detail in that chart as my gx85, that's why I wanted to know from owners who have both if they are experiencing the same problem. I will do some real life shooting the following days to see how what the image looks like, in terms of color I couldn't see any difference with my gx85 so that's good. Its' just that I could see something was off but couldn't put my finger on it untill I used that resolution chart, that might be a problem when mixing the camera's Quote Link to comment Share on other sites More sharing options...
tupp Posted January 20, 2017 Share Posted January 20, 2017 Did you use the same 12-35mm f2.8 lens on both cameras, or did you use two different 12-35mm f2.8 lenses? I wonder what the comparison would be like with both cameras set to "natural" and with the sharpening dialed all the way down in both cameras. It would be helpful to also see raw stills. By the way, are you auto-focusing or manually focusing? Quote Link to comment Share on other sites More sharing options...
dantheman Posted January 20, 2017 Author Share Posted January 20, 2017 Yes, the same lens that I used on both camera's, I"m halfpressing the shutter to let the camera focus and while I do that that the entire screen magnifies so I do get a visual check that I"m in focus. I will do some more tests the next days. Quote Link to comment Share on other sites More sharing options...
tupp Posted January 20, 2017 Share Posted January 20, 2017 Don't trust auto-focus for anything critical, even if you can see the image momentarily magnified. Again, seeing raw stills could help, as those images should bypass a lot of the in-camera image processing. jonpais and Davey 2 Quote Link to comment Share on other sites More sharing options...
dantheman Posted January 20, 2017 Author Share Posted January 20, 2017 I repeated the test with manual focus with exactly the same result so my previous shots where in focus, Allthough I never take stills with my camera's I"ll try to take one, but in what way would that still be helpful?

tupp Posted January 20, 2017 Share Posted January 20, 2017 Shooting raw stills and comparing them to processed frames can reveal the extent of sharpening or other image processing that is occurring in the camera. Quote Link to comment Share on other sites More sharing options...
jonpais Posted January 21, 2017 Share Posted January 21, 2017 I would be very interested in your findings, because to be honest, this is the very first time I've heard someone claim a Lumix wasn't sharp enough - usually, it's the reverse. I always shoot with sharpening dialed down to -5, and the images are still crisp. I shoot with the G85. Then again, I stopped shooting with the Vario 12-35mm f/2.8 because I suspected it was too soft, and this is a lens in nearly everyone's kit. ?

dantheman Posted January 21, 2017 Author Share Posted January 21, 2017 It's not that my g80 is too soft on it's own, it's too soft compared to my other panasonic camera's and the difference was noticeable if I shot side by side, since the intention is that I use my 3 panasonic camera's on a shoot I either have to dial the sharpness down on my other camera's and turn the sharpness up on my g80 in order to make them match. I have to see first how noticeable it is in real life shooting instead of pixel peeping that I"m doing now. jonpais 1 Quote Link to comment Share on other sites More sharing options...
PannySVHS Posted January 21, 2017 Share Posted January 21, 2017 To my eyes, my G6 HD appears to have more resolution than my GX85s HD, with less aliasing and artificial sharpness on the same settings. Started to dialing sharpness down from -2 to -5. Also, from one experience, I got the impression that electronic native lenses might involve some automatic processing to the image. One note on this, in the GH5 thread someone stated about some native lenses that they produce an artificial outline around oof shapes, sharp edges like cut out pieces, so to say. The native lens I shot with back then was the 14-45mm. It was a two cam setup of my and my collegues G6, one mounted to the 14-45, the other one with a boosted 28mm FD. Both lenses were very hard to match in post, even though they were on the same settings. So, maybe some native lenses are key to even more artificial sharpening and rendering because of additional processing. kidzrevil 1 Quote Link to comment Share on other sites More sharing options...
jonpais Posted January 21, 2017 Share Posted January 21, 2017 But Dan is using the same lens on both cameras. And the difference between the two charts is immediately noticeable. I'd be concerned too, I guess. Quote Link to comment Share on other sites More sharing options...
