Although I love many of the features of the new Sony A6500, I feel there's a lot more noise than the Sony A7SII, so shooting and grading SLOG footage would probably 'not be' my first choice. I'm currently experimenting with Profile 3 and Profile 4 right out of the camera for now.
While shooting outside with the Sony A6500 I needed to work with an ND Filter, so I decided to throw on the Fotodiox Fusion ND Throttle Lens Adapter that has a built in Variable ND. For those who are concerned about losing sharpness, I provided a few examples.
Since i'm not shooting with a totally flat image, I only applied some basic curves (contrast) and tried to adjust the white balance. The ND Throttle helped keep the shutter and aperture under control so I could maintain a shallow DOF. I believe most people will end up buying Sony AutoFocus Lenses, but if you want to adapt Canon EF to your Sony A6500, this Fusion ND Throttle is very handy. You can find the FotoDiox ND Throttle Fusion Lens Adapter available on Amazon (here).

Here's another sample where I push the image around with a whole bunch of color adjustments just to see how well Picture Profile 3 holds up in post. From my tests, I think it's a good go-to in-camera profile when you're too lazy to correct SLOG and want to minimize noise.
