    I'm not a fan of the new processing for the linear profiles, I shoot entirely in V-Log so it actually doesn't affect me, but... gross, looks like cellphone footage. I'm eagerly awaiting the S1Hii or S1X or whatever comes next, but they'd better fix that processing.

    Yes, you're right. This is the first thing I noticed when I bought my S5II. Coming from the S5, S1 and even GH5, I'm very disappointed by their new processing.
    V-Log is less impacted but when I compare the 4K V-Log of my S1 and S5 to my S5II, I can see a difference when cropping a bit, details are rougher on the S5II.

    Panasonic is well know for its great image quality, I don't know why they did this on the S5II, maybe to attract smartphone users.

  2. Ita149,

    Where do you have all this information from? If he had lowered the sharpness why should it be "too soft especially for downsampling"? The word "especially" makes no sense at all in that sentence. Don't post stuff you are just guessing from a camera you did not run tests with.
    The camera is still incredibly sharp even at VERY soft 4K settings when downsamped to HD. Compared it to C300 and an Alexa.

    With Exiftool, read my previous post <_< ... Try it on the video and you will see the same informations. Im not guessing.
    Too soft because ive downloaded his clip and ive downsampled it to 1080p and the result is not very good. Do the same if you don't believe me.
    It's pointless to lecture people when you don't even read the post.

  3. No wonder the footage is so jarring. Those values are insane. They might make some sense if you are using 4K photomode and only want to extract a single frame, but for video footage, that is fairly useless to look at. In this case, it would have made much more sense to run at 1/60 (since it is 30 fps), and the aperture should be a higher value to ensure all the footage is in focus. (Again, if it is all indeed on a narrow plane across the frame, and the intent was to look at a single frame for sharpness problems on the side, that makes sense, but looking at this for video quality makes no sense at all). If it is too bright still at say aperture 5.6 or 8 w 1/60 shutter speed, put on some ND filter. It looks like a bright day.

     

    It is also clearly oversharpened, so he shoot experiment with less sharpness for sure.

    I precise it's not my video, maybe his lens is decentered so it make sense if he want to test it at f2.8. Anyway, i've linked his video for the sharpness "problem", not really for the corner softness. If he had lowered the sharpness, his footage would have been really soft, especially if he want to downsample to 1080p.

     

     


     

    It is fine to give opinion if it is based on a good foundation, I think. However, this clip, once I look at it in Premiere, shows:

    -Oversharpened due to settings

    -Corners seem a bit soft, but it could be the aperture chose makes this to be out of focus. In any case, while I have found this camera has good corner sharpness, it is not incredible. It can't compete with my gh3 and Nocticron there..

    -I don't see any significant issue with moire. The little I see is likely from the fact that he shot very fast shutterspeed, and did handheld, so the jittering between each frame makes is stand out.

    -Generally unpleasing picture, but again, due to settings. 

     

    Conclusion: Don't base anything on this footage. Have you tried it yourself?? Have you seen all the great footage out there?

    -Oversharpned at that point with default sharpness and noise reduction is not really good i think.
    -Corners are a bit soft yes, but nothing bad.
    -I don't see moire on this video too and i ve never said it.

    Thanks you for your advice but ive tried it myself and it's not the only case, a lot of videos posted on the net show the oversharpening.
    Download this video and you will see by yourself  :

    A first I thought the LX had better IQ than the 12-35 but absoluty not, it's only oversharpened.
     



     

  4. Yes it's the original footage, just check with ExifTool.
    If you want the settings :

    Contrast -1, saturation -2, sharpness 0, noise reduction 0.
    Iso 200, f2.8, 1/5000.

    To be clear, i never said the camera was bad, and if if we are parrots when we are giving our opinion, very well then.
    So yes the corner sharpness is not bad considering the small lens, but i've compared it to the gh4 with the 12-35.

    The real "problem" for me is the oversharpened video and the lack of IQ on landscape or far subject.

  5. A lot of parrots in this thread, repeating things it seems. The moire comes from your non-4K display scaling the footage. It isn't from the camera.
     

    Of course, it's my monitor, what an idiot i am.

    By the way, download this clip for vimeo : https://vimeo.com/111291938
    Look at the trees, they are oversharpened. And when you downsample to 1080p, it just give a "bad" video quality for a downsampled image.

  6. I had the opportunity to use it again today, and while i still find that on a close subject, the picture quality is great, on a distant subject or for landscape, it's less convincing. Soft corners, more moire than my gh4, and mostly, the sharpness is too high (if I reduce it, the picture is a bit soft but a lot of moire disappears), it seems the camera sharpening is overused.

  7. While it's true the LX is less practical than the Gh4, several things surprised me.
    First, the stabilizer ! Better on the LX than the 12-35, a real pleasure (but apparently less good when recording while moving) !
    Then, for video image quality, the LX is not very sharp at f1.7, stopped down to f2.8 with 400 ISO give better result but with a bit more noise.
    In fact the LX at f2.8 is sharper than the 12-35 at same aperture, quite a feat !
    Otherwise, there are equal, maybe a bit sharper on the LX !
    However, the frame rate is limited to 25fps on the LX in my country :( and CINEV is missing (CineD too but i dislike it).
    I hesitate to sell my 12-35 now !

  8. The 12-35 stabilization is not bad if you don't record with your hands stretched upwards, but the LX100 is better, especially at 35mm.
    I've read on several sites that the LX is less steady while moving or paning, this explain why some people prefer the lx100 stab and others the 12-35 stab.
    Unfortunately i haven't done the comparison while moving, but it seems obvious.
    But the most surprising is the lens, better than the 12-35 on a gh4, it's a gem.

  9. I come back with news, i've bought the 12-35 and i've compared it to the LX of a friend.

    While it's true the LX is less practical than the Gh4, several things surprised me.
    First, the stabilizer ! Better on the LX, a real pleasure !
    Then, for image quality, the LX is not very sharp at f1.7, stopped down to f2.8 with 400 ISO give better result but with a bit more noise.

    However, the frame rate is limited to 25fps on the LX :( and CINEV is missing (CineD too but i dislike it).
    I hesitate to sell my 12-35 now ! The choice is really hard since the Lx has better image quality and stabilization; but the 12-35 could still be used on a future camera, not the compact...

  10. I've already the gh4 and I must buy either one very soon (12-35 or the lx100) but i want the sharpest.

    Does someone has the gh4 with 12-35 and  the lx100 to make a 4k video comparison or advise about it ?

  11. Hi,

    I have a question about GH4.

    it can record 4k@25-29fps with an average of 70-90mbs according to my test, does it mean that 25fps mode has better quality than 29,97 ? Less frames so better quality per frame as it's the same data rate per second for the two settings ?
