I think these shots look very good. Stopped down the lens looks sharp and I find the sharpness of the building that you asked about to be excellent. It also seems to me like you are learning to use the lens and learning some principles that will help you with any lens.
For the kinds of shots in this post, yes it does make sense to stop down and the lens is very nice stopped down. I think with use of the lens you will also find that especially at wider apertures that focus distance is important as the field curvature changes on this lens based on the focus distance as Fred demonstrated earlier in this thread in his review. If you learn the field curvature of this lens, and it takes awhile to learn it, then you can use it to help create the look of the shot that you would like. Also you seem to be starting to understand the bokeh of this lens, which isn't completely smooth and has some structure. Some don't like the bokeh, but I find it appealing especially on a wide lens like this one.
On the more general principles. I try not to shoot in harsh light, but when I do I typically look to shoot in the shade whenever possible to soften the light. I think another thing you are learning is that in the last boat shot, you are shooting into the sun, which can be a nice look, but it is tricky because of flare. You don't have major issues with flare in that shot and I think the lens is doing fine, but you can also expect some of the small blobs of discoloration as smaller impacts of flare. Flare is tricky as just a slight repositioning of the shot can change its impact pretty strongly. In such situations shooting several shots with slightly modified compositions to combat the flare is often a great strategy. You will have to live with imperfections, however, because even the best lenses are not going to be completely devoid of flare shooting into the sun.
Keep shooting and learn the lens as you do so. It will either grow on you or it won't. For me, it is a lens I very much enjoy using....Show more →
Thanks Steve, appreciate the handholding after I threw my tantrum on day 1! There was a comment after the first impressions about satan gargling the light and spitting it back out, that I edited out to be a little more civil.
This 28mm on a full-frame camera is my first, most of my (still limited) experience has been at around 45-50mm, and mostly taking photos of family.
I did recently pick up the 35mm Sigma f2 but I barely touched it, it was just a great price brand new and figured it would be good to have something wider with autofocus and I remember the threads with it performing well in the comparison. So these wider lenses on a full-frame camera are new to me.
With the first brick wall you can see all these really saturated yellows between the bricks, it doesn't exist in real life, it looks more like the fuji. With the x100 and the wide angle adaptor the light doesn't have this funky look to it. Whereas on this, in that stronger light, the bricks just looked funky, more so to the sides. Yes it had a lot more contrast but the sharpness I wasn't seeing it, when I look closely at the bricks they just look messy.
But with the fuji I'll never get sharpness like this longer distance, and there's definitely a lot of quirks with it at larger apertures.
I'm thinking maybe it's the focal length that might be adding to the funk in addition to the harsh light. Like with my 50s, every image is clean, even if some lenses have cleaner images than others, they're all pretty clean, across different light. With the 75's it's even more clean, especially the TTA f2. So maybe that has something to do with it, I'm not sure. I don't see it on the fuji.
Tonnes of issues with the fuji, but I don't feel the need to go past f8 on the apsc, unless I'm shooting something with tonnes of depth like this:
F11 is mostly fine for it. Whereas with the nokton, I'm starting to think I need to go to f16 sometimes with curved foreground and background and contrasty light, like with the 2nd to last picture of the first post.
I'll have a look for field curvature shot gif that Fred posted. [ https://www.fredmiranda.com/forum/topic/1842505/2#field -- this will look different with aperture right? So I'd assume that was wide-open to illustrate it best..]
So for something like this where it's a scene in close distance you'd use f16 if there was enough light? And maybe focus on the mid-point like the tree:
At f11 I feel like it wasn't enough and something like this sort of situation is going to be a frequent thing for me. I think apsc handles this with more ease ... in a way.
F11 with x100vi + wideangle:
I don't mind the blob part of the flare, I see a very similar (single) small blue/red blob in many images where I shoot into the sun, it doesn't bother me:
It's cute. Get's more defined edges and saturated at smaller apertures. There are other parts to the flare sometimes that are bigger offenders, but flare in general I'm okay with.
But with the side-by-side of images taken seconds apart with the boats, blobs probably weren't the right description, it was like fringing I guess, let me get a bigger closeup so we're talking about the same thing:
And I was just not understanding why at infinity distance, with the boat in the shade, and a slight re-adjustment of the frame, why the pole (on the right-hand side) would be much more yellow in one shot and not in the other. And that random yellow showing up on things reminded me of the brick wall comparison against the fuji in the strong light.
With the shot of the building (thank you for commenting) I was happy with most of the front facing bricks at f5.6. Towards the right hand side, which is probably harder to see without opening the image in a new window to get the full res (pain to do with the host but at least it's available to zoom around), where the building starts to curve on the right - I saw an improvement going to f8. But I wasn't understanding why: if it's at infinity, then why does it matter. It was a small improvement at f8 on that side. Maybe that's to do with the FC?
F8 left, F5.6 right at around 400% - BUT, it wasn't on a tripod and this section on the F8 is a little more inwards (towards the centre) compared to the f5.6.
And just for reference, closer to the center at 200% with the a7cii:
Most of this is minor and I don't want to put all this on Steve so you're more than forgiven if you leave me to figure it out 
The main thing for me is going to be clean, sharp images in bright sunlight without the funk - that's what I want to focus on. And lots more where I set it to f5.6 and infinity focus and just see what I get.

It just looks a little crisper, but maybe that's from the export settings, or the light, or lens lottery.
