You're right. I actually do pixel shift with long exposures sometimes. If it is a really cold day, things are often quite still. You also have less issues with water since it blurs itself with long exposures. But you need a rock solid tripod and that isn't just for pixel shift, but for any of the individual snaps along the way.
This is a 30 second exposure pixel shift with the FA 77 limited.

I think the problem is not entirely about lack of motion correction, because the static items in the image (buildings, cliff, concrete wall) are somewhat blurry too. The EXIF says 25 second exposure - if that means 25 sec for each of the four PS exposures (which I think it does), that is a long time for slight movements of the camera or sensor to affect the result. You would need no wind, a rock solid tripod, with minimal extension of the legs and centre column, perhaps with weights attached, and hope for no shutter shock as well. (I don't think the K-3ii has an electronic shutter option?)
I think PS quadruples the difficulty of long exposures. The longest exposure I have used with PS was 2.5 sec. Even with ES and motion correction (KP) the motion of the ferns is still pretty obvious. The static items are OK, but probably show more blur than they would have with a single exposure.

Jau atsakė dėl judančių objektų fotografavimo. PSR tinka tik statiniams objektams fotografuoti ir tik su stabiliu stovu. O su tomis DCU ir RawTherapie - užsiknisimas :)

Already answered for the shooting of moving objects. PSR is suitable only for photographing static objects and only with a stable stand. And with those DCU and RawTheraabout - a snarl

The big thing is that you need to use software to develop pixel shift images that does motion correction.
Lightroom sort of combines the images, but it doesn't adjust for any movement. Water in particular will end up with green and purple artifacts.
DCU will do motion correction. Raw Therapee (my preferred pixel shift software) will do motion correction as well. RawTherapee - Downloads
Without motion correction, images like this wouldn't turn out with pixel shift:

pixel shift not recommended for moving subjects in your case it's water with slow shutter speed .

I have the Pentax flashes. Hands down for the power output, recycle time, battery life, functions and accessories I’d recommend the Godox V1. I shoot weddings for a living and have literally not used another flash since I purchased it. I’ve shoot 8 hour weddings with heavy flash use and I’m still yet to change the battery at an event.

Another happy Godox user (TT350p, V1p, AD200pro, Flashpoint R2v2), with a word of caution: There was a thread recently on how to DIY reinforce the flash hot-shoe on the K-1 because it kept breaking with regular use of heavy flashes. The V1 is a heavy flash, but I use mine mostly on a separate bracket anyway. It looks a bit funny to use the remote controller for a mere 15cm, but works and is less fiddly that the interface on the flash directly. For occasional on-camera use in not overly large rooms, the TT350p is handy, but recycle times are of course noticeably longer with just two AA batteries. I really like the overall well-integrated system. The only weakness that I have found is the optical slave function, which is not nearly as reliable and sensitive as on my trusty Yongnuos (YN560III/IV). I like to use S1 in conjunction with a manual ring flash for 'ambient' light - time to look into matching Godox ring flashes, I'm afraid.

I have a few Pentax flash units for sale since I started using a Godox V1. The Godox V1 units work wonderfully, have great accessories and a battery that will last for hours of shooting at an event. If you do buy a Godox V1 you can use the magnetic dome which does a great job as a small diffuser.

I am not a professional. I have a Yongnuo Speedlite YN585EX. It works very impressively on my K-3. I bought it because it had good reviews.The reviews indicate it is a dedicated ttl flash for Pentax cameras.

We're a friendly bunch. :)
I'd mention I always use TTL moving around outside or inside. I've found it to be plenty reliable enough and try to avoid unnecessary work with minimal benefit for me. For pre-planned shots in a studio or other fixed location I generally have no need for it. In fact I'll sometimes (not often but there are reasons for that) meter the scene set-up with lights and all beforehand, and TTL won't work for that.
So don't worry if you're relying on TTL. There are some long-timers who would say you're not a "real photographer" if you are not shooting all manual, computing ISO, shutter speed, aperture. If that's true I am DEFINITELY not one.

What camera? The AF540ZII doesn't have the analog ttl and auto thyrister modes that makes the older version more versatile on some film models while still working with dslrs. If this is only for dslr models from Pentax that are p-ttl capable then the ii model is fine.
I also like manual control (example: strobist method) and use cactus v6 triggers for that but I'm leaning towards godox. I own the 540, 540ii, several 200/201 models and a 360 in addition to the flashpoint/godox.

The 540 is a great choice; If money is tight, look at the Godox units (I have TT685 and they have other newer options), and when you receive it, check for a firmware update. If you need flash, a higher guide number (more output power) always seems to be better.
A cool option is the Godox Lux Senior - I've ordered one and will let folks know what I think - it's retro.

I've had nothing but good experience with Sigma EF500 flashguns … the second-hand P-TTL unit cost me £5 + p&p, the 'NOS' TTL unit was slightly more.
I've been given to understand they have a tendency to breaking the foot, but no problem here so far :)

As you don't really speak to usage it's hard to advise towards what makes sense as 'investment.' As noted, (P)TTL may not be the game changer you want or seek. The 540 is a good choice, as would be a couple smaller of the godox/flashpoint units and a trigger +accessories for the same or less money, depending on need/use.

We were all there once :)
Using P-TTL flash is an easy way to start and learn, but you will find that if you do embrace the world of artificial light, that manual output will be what you will gravitate towards, especially if you start using multiple speedlights.
I don't have any experience of Godox (I use two AF 540 and two Cactus flashes), but the advice I would give is to get the more powerful units. There is nothing more useless than an under-powered flash for the circumstances.

Another vote for considering Godox.

The 540 is probably your best option from that list. Not sure if Metz still available or has a future. However, I use flash a lot and like you started with TTL, but quickly came to realise manual control was much better for me. Going manual opens up cheaper options, eg Godox and radio connections, which are better than the light comms the 540 uses. Plus with cheaper Godox you may feel less need to be especially careful with the unit(s), which opens up many more creative options. Just a thought ...

Been sick and then unbelievably busy at work so I haven't been around much. Finally just took a day and went north before the weather gets too cold. I kayaked Woods Canyon Lake and really didn't see too much other than the osprey and heron. It was really crowded (as it always is). I was hoping this late in the year that it might have lightened up. While I was up there, I took a drive to Black Canyon Lake to see if the water level had recovered any since May and it was still low. I was lucky enough to see the wild horses and get a few shots.

The camera will check the number of the newest file in the current folder and add 1 to it. So if you are currently on IMGP0100.JPG and want it to go to 200, just rename that file to IMGP0199.JPG and shoot another frame.

The only drawback of your works is that there is nothing to criticize them for. They are not perfect, but they are self-sufficient. And now, when many people are hoping to win a limited-edition lens and are trying to dial the right number of messages, this quality rather hinders. Do you have any picture so that can write a bunch of nasty things in the comments?)))

That kind of noise is fairly easy to deal with in photo editors, and not unusual in flat areas of color. It shouldn't be a concern on prints or when viewing photos at less than 100%.

It looks normal to me. A modest amount of smooth noise evenly distributed. One won't notice it at a normal magnification.
