If you get it, search youtube for a walk through, it's really not that hard, but activation process is a bit clunky. SD card in a camera, export code to card, put card in computer so you can send camera code to website, enter your purchased code, website gives you VLog activation, save to card, put in camera, press play, turn camera off/on, and now you have Vlog. You then put your luts on the card and set camera to use LUT on monitor while filming. Sounds like a lot, but it took 3 minutes following a video...looking at the paper manual, I just laughed and left it in the package.
Tip: Manual mode is touted as what you use if you're "serious" and in controlled conditions on a tripod, I think I agree, but if you haven't already, run a few tests with "aperture priority mode", my results were excellent and combined with the improved autofocus, I felt like like I could concentrate on the subject a lot more than fiddling with dials and buttons constantly.
Why 4 stars? Because it should be included in the price of the camera.
If you're shooting for a living, I think this is a must, if not, you can definitely do without it. It will add some complexity and introduce issues to your workflow, but if you really want that extra detail and control, this is what it gives you, but it comes at a price.
This conclusion is missing the point.
Log allows for the highlights and shadows to be adjusted further in post giving the creator more flexibility.
Vlog is its own color space and more changes can be made before converting to Rec. 709 (a less flexible color space.)
It would be like editing a Jpeg vs a RAW file.
In a sense log gives your camera a baby version of "RAW" Video.
Panasonic claims Vlog adds two more stops of Dynaimc range. I have noticed a slight image quality increase but nothing major.
Id recommended using a Log workflow for any Videographer/film maker who wants to work professionally in any way shape or from.
If you are a hobbyist and make videos for fun I would say stick to whatever color profile you like and save the money.
I wish that Log was included with the camera but the Gh5 is so good for the money I can't complain.
So, it's separate; and that's a good thing. Add that to the price of the camera and it lands right in it's bracket where it should be, so far as price is concerned.
As for how it performs? It's what you expect. It opens the taps on that camera and gives you everything it's got to offer.
While I found the camera itself confusing and eventually bought something else, this particular purchase is something I would consider mandatory for anyone interested in cinema or even video.
