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.
I could remember just a short time ago it was a struggle to find an affordable interchangeable lens camera with 4K internal recording. Even the original Sony A7s didn't offer this, and the Sony A7RII had issues with overheating when recording in 4K. The Sony A7sII is an excellent camera but the price tag of $3,000 is not quite budget friendly. For quality internal 4K recording on an ILC there are cameras such as the Panasonic GH4 or G7, but it's also a smaller sensor camera which some people aren't fans of.
Sony's recent announcement of the A6300 with 4K internal recording at just $1,000 dollars is very exciting news. 4K Video Internal recording (100Mbps) with an APS-C sized sensor (throw a speedbooster on this one!), offering up with SLOG2/SLOG3 with 14 stops of Dynamic Range, and 120fps HD (100Mbps) high frame rate are just a few notable features. It is certainly offering a lot of what the more expensive A7sII has, with some features far better like the new Auto Focus system.
Now there are some features that are limited such as no headphone out port, and 30 minute video clip lengths. It's not clear if the videos longer than 30 minutes will continue, or if it will just stop. But by using and external recorder, you could probably get around that. Regardless of some of the small cons, for the price there's a lot to like in the new Sony A6300 that could pull a good market share away from current some Panasonic GH4 shooters. This is a camera I think will work very well next to my A7sII and i'm planning on getting one, unless of course Panasonic announces a killer GH5 soon and then i'll have to rethink...
