Sony a7Rii vs Sony a7Sii, which one do I use the most?
I know I promised a Sony a7sii review a long time ago, already a lot of video comparisons between these two camera, but I have been using both for over 8 months now so I might have a different take on this and there is one camera I use more than the other, so I thought I would share.
I'm not going to guess what camera you should get based on your shooting style since I am sure most have already decided to own one of them by now.
Comparisons:
Both have IBIS, both have the same weak but tiny battery, very similar color science (not the case for a7s original), both do not overheat now
a7rii has a back-illuminated structure sensor that can only go up to 25k ISO for video mode
The a7Rii works best in cropped mode for video, while the a7Sii works best in FF mode
a7Sii is better in low light, but that is only when you get crazy high ISO like over 12,800
But watch out when the a7s mark III comes out with the back-illuminated structure at 12mp that should be amazing!
a7sii has slog2 and 3, while the a7rii only have slog2
a7Sii has aliasing in full frame mode when shooting in 4k where as 1080/24p doesn't have any aliasing
Slog2 starts at ISO 800 for the a7Rii while the a7Sii starts at ISO 1600
A7Rii has 42MP great for stills like landscapes, a7sii 12MP
a7Rii has much better AF-C since it has phase detection AF
a7Sii has slog assist
a7Sii you can shot for slow motion and playback in camera the slow motion, a7rii can't
a7sii can shoot 120fps at 1080, the a7Rii 120fps at 720
a7rii you can shoot 4k in aps-c mode, the a7sii can't
a7sii it is easier to shoot 4k wider than than the a7rii
both has bad rolling shutter
Since the a7sii works best in FF mode, you will get more shallow DOF for shots like interviews
I use Sony a7rii more for the following reasons:
I have created a Sony a7Rii course and a Sony a7Sii course, both I have pixel peeped a ton because these courses take months to make!
When I don't have control over the lighting and it's a high dynamic scene I shoot in slog2, the other times I am using a more linear creative style like Standard, I typically over expose slog by about 2 stops, well guess what happens, most of the time when I am shooting in Standard creative style with the correct exposure and then switch over to slog, the ISO jumps to 800 and the exposure is right where I need it, two stops too bright. With the a7sii it jumps to 1600 or 3200 and then requires downward exposure change, if you don't run and gun like I do this might not be a problem, but for me having to grab and ND filter when it jumps to 3200 is an issue.
The a7Rii AF is better, I use the a7rii a lot on a gimbal with AF and it works a lot better than the a7sii
I don't have to worry about moire when shooting at 4k.
When I am shooting stills I do enjoy having 42MP for portraits or landscapes
I mostly never shoot above 12,800 ISO both cameras have about the same noise below that.
For interviews I use the a7rii for my wide shot in 4k crop mode and the a7sii for my close up at 1080 full frame mode, the a7rii will give me a nice detailed wide shot while the a7sii will give me nice shallow DOF on the close up.
