Possibly, but I have not tested it. I do tend to shoot these lenses wide open 90% of the time anyway, so the focused subject is already as sharp as it can be. What really changes with FC is the overall rendering across the frame.
To me, the lower the field curvature, the better, even with classic designs. My guess is that to keep these lenses as compact as possible, FC and vignetting are corrections that get relaxed. Still, a thinner sensor stack seems to deliver more optimal results, even though the lenses were originally designed around a thicker stack. A thinner stack should reduce outward FC (correcting inwards), just like mounting an M lens on an E-mount body usually increases outward field curvature....Show more →
I also shoot mostly WO, so the focal point sharpness is what I care about as well, so FC is manageable if resolution is fine.
Inward FC is one of the only aberrations I just never enjoy. On the new 35/1.4 LLL, I was bummed to see it as part of the optical design even on it's intended sensor stack thickness.
Unless I am shooting specific applications like astro or landscapes, I actually prefer pretty much all my native e-mount glass on a modded sensor for the same reasons you do The GM 24 and such become even smoother.

I can't see myself being satisfied with either of these lenses when the Sony 35Z or 40G are only slightly bigger and seem hugely superior from an IQ perspective. Maybe it's just these samples but what I've seen so far looks mostly dull and unsharp.

I'll be shooting the SG on my nikons. If the lens is ~$100, tiny and AF, that is the reason.
I prefer 35mm over 40, I want a pocket size everyday lens that isn't f4.5, and I don't want a $100 sony adapter for e mount lenses I don't have.
Sounds like plenty of reasons for a frugal Nikon shooter to be excited.

I wish I could get excited by another 40mm, but I just can't.
A small and "fast"-ish 35 is what Nikon Z is missing. Heck, no full frame mirrorless system has had a small, cheap, faster than 2.8 35mm while I owned a camera in (X) mount. Modern 35/2 AF are all kinda chunky.

TTArtisan 40mm f2 is a 37mm, I believe. So within the normal range for a 35mm lens.

I was comparing the TTArtisan 40mm f/2 closely with the new CV 40mm f/2 Septon and other 40mm lenses today and noticed something interesting about its effective angle of view. The TTArtisan has quite a bit of focus breathing, which is a trade off they made to keep this compact AF design. At infinity it is indeed a true 40mm lens, but as you focus closer, the field of view expands and it starts to look wider, closer to 38mm at closer distance. Essentially, the closer the focus, the wider it appears. Technically, all FLs are measured at infinity, so calling the TTA a 40mm lens is accurate.

Looks like the embargo for the 7A 40/2.5 is up today. Metal mount and rubber gasket was a shock.
After getting the 7Artisans 40mm f/2.5 today, I came to appreciate the TTArtisan 40mm f/2 even more. It's 8mm longer, but the build quality is in a completely different league. The 7A feels almost toy-like...too light, with a mount that looks like metal but feels like plastic, and everything else, including the buttons and focus and aperture rings, is plastic. The AF is decent, but the overall feel is nowhere near the TTA.

It was bad that you could SEE the poor exterior quality of the 7A from the early leaks.

I'd be interested to hear whether your experiences of the two lenses corroborate with the Chinese review, from an IQ perspective (i.e. that Viltrox > 7A > TTA). Thanks!
Personally I'm holding fast to my Sigma 45/2.8, much as I'd prefer a 40mm or even 35mm FL, until another lens is proven to definitively trounce the Sigma in the quality of bokeh and OOF/transition rendering.

To be fair, it's a very light lens and the image quality is decent. The real issue is the feel, it comes across as quite plasticky. If you are just using AF and mostly shooting wide open, it probably won't bother you much. But it is not a lens that feels satisfying when manually focusing or adjusting the aperture. The reviewer yo posted above mention a metal mount, but I think the appearance is a bit misleading. It looks like metal, yet it feels more like painted plastic.

Reviews should be coming soon, some people got their pre-prod samples from SG. Here a few more samples, surely has some "character" in close focus shots... link to google drive

Keep in mind reddit is downsizing/compressing images, a bit unfortunate to share them there...
Try to open with old reddit UI and click on image, it opens in a new tab with a better resolution (though they are still somehow compressed, but better than in the new UI)

Reddit's compression is so bad as to make it not even worth discussing IQ on images hosted there IMO. The overall rendering reminds me a lot of the TTA 40.

In that respect, not a single YouTube influencer would need to publish a single "test video".
The GM 24 and such become even smoother.
