Take this considering I am no professional nor technical expert
Mounted on the camera it feels nice, surely better than the 2470 gm...
Yesterday night I was in the backyard of a friend that was testing his telescope. I did some shot on the tripod just to see what is like shoot milky way compared to the 2470
The manual focus was "different" compared to the 24-70..
On the 24 70, the sweet spot where I have stars in focus is quite on the right end of the scale. And it changes quite easy if you don't have a very delicate regulation
At 14 mm it was way easier, in the range from 9m to 12m in the photos I checked the stars were in focus. This is around at 3/4 of the scale.
I guess it's just the focal length difference that makes it different/easier
I tried a few random shots indoor in my room with low light, the autofocus felt slower than the gm
Anyway this weekend I am going for two weeks vacation in the US and will have plenty of time to test it ...Show more →
If you check the exif data you may well see that although the camera is displaying 12m, the exif data show infinity. Certainly on my lens that's often the case. Note also that the difference in lens position between displays of 12m and infinity is minimal.

I always use a CPL in rainforest/waterfall photography, even at 14mm, and the results are fine. It's only with large areas of sky that you need to be more careful with a CPL at the wide end of this lens.
I personally have no experience with rear filters, but wouldn't like to have to take the lens off the camera every time I want to change filters.Nisi have a few filter systems. The one I use is the S5. When used with the right adapter for the lens, I've seen no vignetting with with either the Sigma 14/1.8 or the Sony 12-24. Because there is no Nisi S5 adapter for the new Sigma lens yet, I've also tried the adapter for the Sony 12-24 on the new Sigma zoom (with an added rubber band on the lens to make up for the difference in diameter) and again see no vignetting.
Note that the BHphoto website information I saw about a week ago about filters with the new Sigma lens was wrong as it pertained to the old HSM art lens which has a different diameter. Hopefully they will correct that some time.

First of all, thanks for sharing your testing methodology and reults. I have a question about the Nisi adapter. Are you rquired to use the Nisi polarizer that's built for the adapter or can you use other brands and if so, what size?
Incidentally, I just returned a copy of the 14-24 that was quite soft on the right side from, even at f8. I'm waiting for a replacement copy. Fingers crossed!

I think the Nisi S5 adapter only suits the specific Nisi round filters made for that system. You can use any third party square/rectangular filter if you add an extra attachment for that purpose.
Shame about your decentered 14-24. It will be very suprising if the replacement isn't much better. By F8 there should be no difference between any of the corners across the full range.

I recently bought rvh23’s Loxia 25. It’s very nice. I think it will go well with the Sigma 14-24.
I’ll be interested to see how the Sigma compares against my Canon TSE 24mm. As I still think it as the best corners of any 24mm lens for landscape. It beats the Loxia, though the Loxia is sharper in the centre frame.

Thanks, that’s what I thought. Hopefully Nisi comes out with a version for this lens soon. Have you tried the Nisi Landscape CPL? Curious how it compares to their standard CPL.

Good to hear you're happy with the Loxia 25. I agree that a Loxia 25 or Nokton/Loxia 21 pair perfectly with the Sigma zoom. That's exactly the 2-lens kit I am now using (Nokton 21 in my case) to cover the very large majority of my landscapes. But I expect to only pull out the CV for sunstars/shooting against the sun, as sharpness wise I see no benefit over the Sigma, and color with the Sigma is also very nice.
I'm surprised your TSE is sharper than the Loxia in the corners, unless that's when you center focus (as the Loxia has some moderate field curvature). I used the TSE as my only landscape lens for several years, but once I tried the Loxia 21 and 25 (and improved my focus stacking methods to compensate for lack of tilt) I never looked back, partly because of improved corner performance with the Loxias.

I've only tried the Nisi CPL+ND64 combination filter, and like it a lot as a single filter solution. But in my case, when I need a CPL, I usually also want to slow water motion down. Until Nisi bring out an adapter specific to this lens, I am using a rubber wrist-band on the front of the lens to increase it's diameter slighlty, which allows me to use the Sony 12-24 adapter for now.

No I focused for the corners.
I’m not talking about shifted corners, but non-shifted corners. The Canon TSE 24mm requires a very precise flange distance when adapted on Sony. Even the MC11 isn’t perfect. Have to shim adapters. The 24 TSE has very even sharpness from centre to corners. Where the Loxia dips in the corners, though slight the TSE has the edge.

Interesting finding. When I shot with Canon, I used to have the 24 TSE. Did not get much into the shift or other movements, though that was the eventual plan. However, when I got a Zeiss 21mm ZE (which I think is the optical formula as the Loxia) and I looked (pixel-peeping) into the corners, I found the Zeiss was clearly head and shoulders better, not just in resolution, but also and especially contrast. In general, CA was more controlled there too. All unshifted. I finally sold the TSE because I found that I ended up reaching for the Zeiss everytime I went out, though, TBH, this was more for the rich rendering and pop more than corner performance per se. Anyway, all this is a little side-track of a side-track of a side-track from the main topic of the thread so I shall desist!

You guys do seem to be right. I retested my Loxia 25 and Canon TSE. The Loxia is sharper. By f11 they are the same, but at f8 the Loxia is slightly better in the corners and a fair bit better in the middle of the frame.
Looking forward to getting the Sigma 14-24 next week! In hope for a good copy!

I still use the TS24 to get panoramas esp. indoors. But our Loxia is clearly ahead in sharpness over the full frame. Stacking the 21 images indoors doesn;t work as good as using the TS, so I keep it.

My copy arrived on yesterday.
Tested today and extremely well centered.
Great lens and great copy.
Lucky man
I received another copy today, but no cigar. Like my first one, it's great at 14mm even wide open. But this second one is relatively soft in all corners at the long end wide open (although good stopped down again).
Incidentally, I took my first copy out on a "real-world" 6-hour astro session late last week, and was very impressed with the results. No CA or coma to speak of even wide-open makes for really clean corners, probably the best I've seen from any UWA lens at 2.8.
