Lots more testing today, this time with some A/B with the TTA 75/2 again. Over and over, the TTA images are half a stop brighter at all apertures when shooting in Aperture Priority mode. I have adjusted the TTA exposures down to get closer to how they came out of camera with the Viltrox.
Wide open, the Viltrox often has the edge...sharpness, contrast, "more" bokeh, less flat color thanks to the microcontrast. The Viltrox does, however, have noticeably more vignette. The LR profile for the TTA fixes vignette more evenly than the Viltrox profile, for what it's worth.
Even by F4, the TTA distant bokeh has become smoother, and by all of my metrics, BETTER, than the Viltrox. This is disappointing, because the Viltrox actually has the built in advantage of being a longer focal length and should still be dominating here.
At F8 I really prefer the TTA rendering of distant foliage. Less mechanical, better bokeh balls.
Scott - again, in these side by side bokeh tests - I just can't see what you're seeing. The out of focus rendering is so similar between the two that I have to think the only way you could ever tell the two apart, especially in the stopped down renderings, is by taking out a loupe on a giant print and going over them with a fined-tooth comb. I just don't see a big difference at all. So much so that, because you didn't label these images, I'm not even 100% sure which lens is which to be honest. I THINK the left is the Viltrox because it has larger specular highlights in the wide open shot, and the framing looks a little tighter, and you also put it on the left in the distant detail shots in the next post - but then that doesn't jive with your text for the f/4 shots, because the left image looks smoother in the background to me than the right, especially in the green foliage areas just to the right of the post. (though further away, it might swing slightly in favor of the right image in the space between branches...but again, they are so close as that the difference is so negligible to my eye.) At f/8, I might give a slight edge to the TTA, but again...they're so close I don't think I would be able to tell them apart if they weren't side by side. Wide open, though, I prefer the left (assumed Viltrox) image by a larger margin than I prefer the right image on the f/8 shot. But again, both look very nice wide open to my eye.
Well you're now on the record across multiple threads and multiple lenses to "not see what I'm seeing" so we can safely assume that (and I don't mean to sound dismissive) you have lower quality standards than I do for IQ, or at the very least, aren't bothered by the same bokeh characteristics as I am. That's fine. To repeatedly tell someone that because you don't see something that it's not there is just silly. I don't need to blow anything up, I can look at the images at 100% on my 5K monitor and the differences are stark to my eye. Would the bokeh differences matter at normal viewing size? Not really. Doesn't mean it doesn't exist.
All of my posted samples have been Viltrox on the left, which was said originally and I thought very obvious since the subject is clearly bigger being 10mm deeper 
I think you are being incredibly dismissive - coupled with the 'it's ok to like wrong things' comment about the hood. And frankly it comes of as a strange bias against Viltrox for whatever reason. You have described the Viltrox as having bokeh that 'is on the border of distractingly busy', and 'has a strong soap bubble effect', and yet your samples don't show that at all in the vast majority of situations (except when focusing at longer distance, where it definitely does get busy)....and then you post these comparisons with the TTA, which you describe as having beautiful bokeh, and yet the differences are EXTREMELY minor, and frankly in many cases look smoother on the Viltrox. I'm not some noob who has only shot with a couple lenses, so dismissing my statements as 'you simply have lower quality standards' is just crazy. There are lenses with massive differences in bokeh....these two are not them.
