Looks awesome! Hope to see more from your neck of the woods.

I found some time to load the v6 TAP firmware onto my adapter and in some quick testing, it appears the AF is much improved as others have said... more responsive and AF-C seems usable. In AF-C there's no longer any blatant pumping but it does constantly seem to be adjusting focus, perhaps because it's compensating for camera movement with such a shallow DoF. I'm not sure... I need to try it on a tripod I guess. At least it seems somewhat usable in AF-C mode now.
A couple things I've noticed that I wouldn't mind some verification from others on...
I'm not sure if this was the case before the v6 TAP update but the A7RIII now only lets me move the focus point (expandable spot) within the confines of the PDAF area of the sensor. With other native lenses, I can move the AF point anywhere but with the TAP, it's confined to the PDAF area. Is this new or was it always the case?
In terms of AF performance, in a well lit room large expandable point will get focus nearly anywhere in the PDAF area. As you make the spot smaller or lower the light, the left and right edges of the PDAF area become unusable, but strangely, the top and bottom areas remain very usable. My conclusion from this is that shooting people will need to be done primarily in landscape orientation. Using portrait orientation will mean your subjects head is mid-frame and a decent composition will likely require serious cropping off the top.
If you set the lens aperture to just a bit before the center point between f/1.1 and f/1.4 you will get a lot more contrast/sharpness on center than at f/1.1 but the ISO (exposure) is the same as f/1.1 and the DoF is still insanely shallow with great bokeh. This seems to be the best compromise for character, bokeh and some decent sharpness on center. I'm guessing this is effectively an aperture of about f/1.2 with a T-stop of f/1.4 as it requires one stop less ISO than my FE 55 at f/2. So I think my go to aperture setting on this lens will be just wide of the half way point between f/1.1 and f/1.4.
The other thing I've noticed is that the TAP adapter allows you to get better than the specified 70cm MFD... I can get focus confirmation to about 50cm by setting the focus dial on the lens to the minimum setting and using the TAP to AF. In fact, as you've all probably noticed, to get the full range of focus with this lens, it's essential to manually pre-focus for less than 1m, about 2m and infinity depending on actual subject distance.
Is all this consistent with your findings... or what are you seeing?...Show more →
According to 7A themselves, the lens is an actual 1.1. On my copy, I actually get extra light as I move from 1.4 to 1.1. I can't remember what the ISO difference was but I compared the 7A to the FE 50/1.8 for exposure earlier in the thread. I thought it would be a good comparison since both lenses supposedly have a T stop equivalent to what the F is.
Otherwise, my findings have been pretty similar to yours. Since the update though, I have been able to get pretty good AF accuracy even in ultra low light (around the central area of course).

This lens does not work on APS-C or m4/3 cameras. The back of it protrudes very far and fouls against the interior of those cameras preventing it from being able to utilize the full focus range. I think the furthest away I could focus was 8ft...
Only for use on full frame bodies.
Thanks! Definitely good info for those considering use with an APSC body.

correct. my copy. as previously mentioned. never sharp edges. I do not have any problems with that. see it as a characteristic of this lens. my closet is full of lentils. the sharp on the edge can.
By the way, nice pictures on flickr 
+1 on that. Sharp lenses that are much closer to optical perfection I have. It's interesting lenses that I love though.

So I have a two prong reaction when shooting with the 7Artisans 50mm. At first I'm like WTH did I just shoot with this dreamy arse lens when I could of used something like my Sigma 50mm 1.4 Art. Then a week later I look at the photos and I'm like, wow this looks really different from anything else I shot, I like it! Lol
Here are a couple new ones with the 7Artisans 50mm 1.1 + Sony A7 II + TAP:

Yup. lol. Great shots btw.

Cross posted with the FE Image thread. Here's a few shot at f/1.1-1.2 on the A7r3 + TAP
Nice!
It's very interesting to be looking at the various images from everyone in the thread as they all share distinct character traits. I regularly share shots with my photo buddies outside of the interwebs and without fail, they ask if it was the 7A every time I send them a shot from it.

There's too much temptation in this thread.
Must.
Resist...
The 7A, IMO, costs next to nothing (for what it is) and is worth a try if for nothing else. Just do it!
