Well, I see some aliasing, but nothing major. The trouble is: "crop mode"!! I'm starting to think that, with all the effort Sony has put into stressing that the mode to use on the a7R II is the S35 mode, if I had one, I would be shooting FF: it seems just as clean of artifacts (or unclean, that depends on where you set the bar), rolling shutter is a lot better (similar to that of the 5D3), and my lens set can shine without the need of a speedbooster.
Now, let me see...
a7R II - $3200
Batis 25mm f/2.0 - $1300
Sony 55mm f/1.8 - $1000
Batis 85mm f/1.8 - $1200
TOTAL - $6700
Not yet, Samuel, not yet...

The noise is better, that's a huge plus point. Maybe less exposing over and taking down, so range would be better.
Those Batis lenses don't have hard stops, pain to MF or with a FF IMHO.

I'd add the 35/1.2. That and the 21 both focus down to 0.5m, unusual for RF lenses. The three also share a similar physical layout (though not the 50 1.5).
If only I could figure out how to declick them though. Suction cups???
But then shooting stills on the A7x's, I've found Voigtlander lenses to give rather bizarre colors.

(Those three lenses would be what I'd use for photography and for travel; for video I'd keep my set of vintage Leica-R primes: 24+35+50+90+135+180)

Personally I'd stay away from the FE 55 F1.8. I find the closest focusing distance to be lacking for a prime and the manual focus was random. But Batis all the way!

I tried the 25mm Batis at my local store and was super impressed with the manual focusing. The lack of hard stops isn't a deal breaker for me. The focus ring is so precise and smooth and my A7S outputs such a clean and clear image to my external monitor that I don't require hard stops to tell me where my minimum or infinite focus distance is. Most hard stops are not calibrated right at the minimum or infinite anyways.

Finally a 100% crop from a chart, at cinema5D
The FF mode looks really, really good. Worse than APS-C, but close enough for me. If I had an a7R II, I'd be shooting FF most of the time (the only use of APS-C would be when I have to crank up the ISO: it's much cleaner, and you can use a speedbooster which gives you another extra stop of light). FF is slightly softer but this is super-sharp 4K ayway so I'd rather have decent RS performance; plus, compared with actual FF, the speedbooster makes the lens slightly softer (my tests), so if that's what you're going to use then the sharpness advantage of APS-C is only at the center of the image, at most.

What kind of bizarre colours?
You need to make sure you've got proper profiles for the A7s in lightroom, because the adobe ones are awful. But that's true regardless of lenses. IMHO i find the voightlanders wonderful rendering, so much so i've taken to using them for video across the board despite having a full set of zeiss contax.

I'd be worried about what Vimeo is doing to the footage. I'd be concerned that this doesn't reflect the original. The reason i say is that down sampled version doesn't look very good, although AEs downsampling isn't so good anyway (plus i think it's a fairly sharp downsample by default..?)

Sure but i can't pop a wireless follow focus on those and have them calibrate and work properly. Sometimes i use WFF on a gimbal with the A7s and voigtlanders.

Indeed: the 100% crop that Cinema5D posted looks A LOT better than these vimeo/youtube samples.

You'd have to view it at exactly the same resolution it was originally, otherwise it will be scaling for your screen display and you'd get aliasing that way...
So download and view 100% only.

Hi Paul, this isn't the right place for this but I've found that Voigtlander lenses on Sony sensors yield either washed-out dull colors or neon-bright colors. It's like the middle gradations are missing, resulting in a plasticky deadened look. High global contrast, low micro contrast. Post processing would no doubt help, but with my Contax and Leica R lenses the colors just come out perfect (95% of the time I use the default "medium contrast" profile in LR).
As a disclaimer I should say that I really want to like the Nokton--ergonomics, price, 0.5m MFD, etc. all very good. Bokeh and sharpness are fine (not my biggest concerns). But I just never got good colors from it (or from the 40/1.4 and 21/1.8). I've tried several copies. I recently raised the issue again in the thread below. When I see those colors in the OP's photos, I recognize the CV look immediately. Dull, gray veil with aggressive greens and reds and purples. I see the same phenomenon in the CV f/0.95 MFT lenses.

Maybe it's just down to a personal thing against the "Voigtlander look."

Odd, i've never had the same feelings, quite the opposite. Do you have an image that represents what you don't like with the original RAW file. I had huge issues with colour in general in Lightroom until i got some proper profiles for it. Have you ever side by sided a colour chart to see if it's quantifiable? I'd be interested in knowing, emphasising certain saturations and colours through the lens IMHO would be quite difficult to achieve. I can understand tinting of colours and contrast but filtering certain colours seems a big ask...?
