    Focus issues with your X5?

    I have calibrated my lens (Oly 12mm) over and over and checked focus is ok when shooting photos. But as soon as you shoot video in DLOG or CINE, something weird happens. Attached is a JPG (f/6.3) - close, but not the sharpest aperture but serves the purpose here - it's clear that the lens is calibrated and the subject building (sorry, boring I know) is in focus. So far, so good. I can take focused photos.

    But when I switch to video mode (infinity focus, f/6.3) things go south... When you choose DLOG and CINE, the image looks soft and mushy. But as soon as you choose NONE, it goes back to being in focus again like the JPG?!?! - See screenshot.

    Attached is examples taken minuts apart from same position after the same calibration. All shot in MF, ISO100, f/6.3, Auto WB, (-1, -1, -1). Latest FW on everything.

    Here's a video that clearly shows the X5 go from out of focus in DLOG and CINE and going back in focus when switched to NONE:

    yep a well known issue with the current firmware and DJi know this and hopefully will rectify the issues sooner rather than later. For now it's best like you mentioned to shoot in NONE

    What about 1080p - will that also look soft?

    Yep I had this same problem. Super weird. Shooting in 'none' is just fine.
    What I did find is that I believe it has something to do with the dlog and cinelike sharpness values. If you go through each custom sharpness value 0 and above, they are all identical.... Except +3, which looks like 0 used to be. So it is functional if you must shoot in dlog, you just need to crank the sharpness all the way

    I've found simular results but hasn't been too bad. Have been able to bring back the sharpness in post with no problems and still keeping it clean.

    I am hoping the same update will also allow you to stay in a mode in video and be in a different mode in photos.

    Oh, your post made it sound you had it and actually tried it. Get it and then come back with your opinions. I had it since day one and, off the current options, NONE provides the best results.

    Did a quick calibration today but did not have time to fly started snowing... But was able to go out tonight and shoot a quick test! Did my calibration work out? I think its clean but not the sharpest and its straight from the camera nothing done except white balance shot with None picture style. 1-50 f1.7 iso1600 24fps 4k

    Did you attempt to recalibrate it at the 0:35 sec mark? If so it looked more in focus before you did that.
    Night time is tricky, the sensitivity on these camera's is still pretty bad and results in night time stuff looking pretty mushy at the best of times... Only real way to test calibration is during the day when you have some nice contrasting lines to really be able to judge your focus.
    Try shooting on iso800, I found that worked the best for getting decent exposure while losing the mushiness of high iso. It is still there for sure but a little better in my opinion.
    Try taking some night time photos as well, the camera can handle those a lot better!

    Was setting my focus point at the horizon but did not work as planned lol yeah i did a quick calibration but the weather is horrible lately around here. Will take my time as soon it gets warmer but i am doing some tests with my Osmo and i am happy with the results so far just need my Heliopan graduated filter asap.

    You had it since day one and you shoot None since day one i guess you do not shoot anything comercially like music videos or serious production with footage you cannot color grade. yeah its fine for flying in your backyard but guys like me actually make money with footage we shoot and we have to provide flat footage for the Colorist to do his magic.
