What amount of purple fringe is OK for 16/1.4?

I had been reading and viewing a lot of reviews of the high-praised 16/1.4 and finally decided to go for it.
So I got a second hand  (still not cheap for a hobbyist) 16/1.4, still on warranty, in seemingly perfect shape. Have had it for about a week now, and had just a few opportunities to shoot.
What confuses me is the amount of purple fringe - I got this lens with the main intention to shoot in poor and/or difficult lighting scenarios. And this amount of purple fringe is very likely to give me hard time in quite a few of those. Can other owners of this lens comment, whether this is something they get from their lenses or should I send it to Fuji to take a look?
I am in Eastern Europe, there is not a vast Fuji dealer network here. Therefore, I want the comment first.
If this behavior is expected, I'll need to rethink having this lens...

In this one you can see the purple fringe around starrs even when zoomed out

And here is a crop from around the center of the frame. Focus a bit off, but thats my fault.

Will appreciate any feedback.

The second image seems like something is seriously off with the lens, though I would be interested to know what RAW processing software you're using. I have seen this issue on backlit subjects before, though not nearly this bad. Sometimes Iridient Developer performs a little better in these situations, though Adobe has improved their Fuji performance.

In regards to the first image, I think this is actually fairly normal for astrophotography with this 16mm when shot wide open at f/1.4. That fringing is a common critique that I've read in many reviews which look at this lens for astro. That's one reason I've never used mine for astrophotography, you have to stop it down to about f/2.8 to get rid of that, which negates much of its advantage aside from being a wide focal length. That being said, I've never encountered such bad fringing as is shown in your second image.

Oh damn, that looks bad. I'll check my copy of XF 16/1.4 when I get back home.

I've made a test shot against the sun to simulate similar conditions while the sun is still up, but I realised I have left my memory card reader at home.

 

Edit:

It's not perfect, but much better. And can be easily corrected in post (well, in ACR at least, because somehow purple defringing in Capture One doesn't work at all).

XF16 lens is significantly based to various corrections via software/firmware of camera.
I.e. an old camera with such relatively newest lens but without appropriate firmware update may produce strange artifacts, at least theoretically.
Worth to check. It's easy and free.

Not likely, we are talking about raw images here.

      How to turn OFF the wifi antenna

      Does it use wi-fi when you are not specifically attempting to transfer files?

      How to turn OFF the wifi antenna

      By Rupal · Posted

      Hello dear Fujifolks - I come from 54 years of shooting Nikon cameras, and this is my first Fujifilm experience as I've just sold my Nikon D7200 in exchange for a tiny but endearing X-T20. Very pleased with it as it's so lightweight, but very well built. But takes some getting used to the menus and settings after Nikon's DSLR functional simplicity ! I'm working on it though and slowly coming to terms with the new system. My question for now is this: is there any way to turn OFF the wifi antenna in the camera ? I'm particularly wifi signal sensitive and have no intention of using that function as I do all my editing and printing on my PC. I've checked the wifi menu options but cannot find a simple wifi ON-OFF selector. Thanks for your help and I'll be back with more Q's when needed. Blessings to you all...

      pocket wizard and XT5?

      Has anyone successfully used pocket wizards with an XT5? I cannot get it to fire.  Do Fujis and pocket wizards get along? Thanks in advance for your wisdom on this, kind readers!

      Grzegorz, Go to the Networking Setting in your camera menu (the last one at the bottom - unless you have a My Menu then that is the last one). There, go to Network Setting and choose the SSID (name) of your WiFi network, type in the password, choose "SET". If you have a functioning DHCP server on your network, the camera should get its IP address (and Subnet_Mask and Gateway). If not, you can enter these manually. It is a little tricky, there will be some zeros already here, move the cursor after the zero and use DEL to delete it and make space in the input fields for your own correct values. If you do not know what to enter, have a look at values in the network settings of your computer and use the same except for the IP address, try some fairly higher number, hopefully you hit an unused one. Usually the values would be something like IP: 192.168.1.188, Subnet Mask: 255.255.255.0, Gateway IP: 192.168.1.1  or something like that, take clues from your computer. The camera and computer must be on the same network. Then in Connection Mode on the camera, choose Wireless Tethering Fixed. And half-press the shutter to exit the menu and get in shooting mode. The red LED should be blinking. If you can look at your network devices, e.g. on your router, you should see the camera there. You can see check the camera settings in the camera menu in the INFORMATION item of the Network Setting menu to see the MAC address of your camera and look for it in the list of devices on your network.  Then use the tethering in your software, e.g. in Capture One. The camera may not show immediately, take a shot and then it should show in the list of available cameras. Good luck. Report back how did you fare.  PS If you have a Windows machine, you need to have Bonjour installed and running. Macs have it.

      X-T30 II Eye Sensor + LCD Image Display viewmode not working

      By grizzski · Posted

      Hey all, I just got my first camera. The X-T30 II. It seems the Eye Sensor + LCD Image Display view-mode is doing the exact same thing as just the Eye Sensor view-mode setting. Any ideas why this is or what's supposed to be happening? Firmware Version: 2.04
