PhotoRotterdam: Prime de-noising was by far the most impressive and useful tool in the market, so I’m looking forward to the tests comparing the two.

Demosaicing is the strength of DxO, so if they really have improved I might upgrade.

Give a test to Topaz DeNoise AI too. I didn't test DeepPRIME yet, but Topaz is better than PRIME, and it works on processed images too, not only RAW.

Cannot afford it, but it is beautiful!

For future galleries, it would be nice if most of the "landscape" shots are taken at landscape aperture (f/8-f/11) and on tripod. I am sure the XT-4 is a good camera but it's hard to see the image quality on photos taken handheld at f/4 with blurry edges.

DavidB77: I own this Lens and edge softness is in fact field curvature. The trick to have edge to edge sharpness is to focus somewhere between center and edge, for example one vertical third line. It is a little annoying not to be able to focus in the center, but pictures dramatically improve with this trick.

You're right Lessiter, it makes act of taking photographs less fun and less reliable. You can't just use hyperfocal distance and have everything sharp in the picture. But with this lens, focusing a little off center work pretty well and is reliable enough. It seems that Pentax do not correct field curvature anymore on new lenses, I have also the problem with the 20-40 Limited but with this one, I never was able to fully correct field curvature... and I sold the lens.

EXkurogane: $1399 for a crop sensor ultrawide lens

Seems like Pentax plans to continue selling lesser cameras compared to others, like they have always been 😂

Canon, Nikon, Sigma or Tamron do not have any great crop UWA zoom, just entry level UWA lens. Tokina has this kind of lens, but they're not professionnal grade lenses. Only Fuji now has a modern and great 8-16mm. I am glad that Pentax care about its Landscape crop shooters.

Ergo607: Looks big, but I don't think it is much larger than the DA 12-24. Over the 12-24 it offers large aperture (f/2.8 vs. f/4), weather sealing, probably faster focus, better IQ (and the 12-24 was already very good) and the focus clamp (of which I think it is a nice touch!) Not to mention that it is more wide-angle.

Good move, Ricoh. Would sure like to try this one...

It's is not longer, just larger, but it's still relatively small. It also has HD coating, DC motor, and far less chromatic abberations than 12-24mm, yes good move! f/2.8 vs f/4 also allow to lock focus more easily in the dark.

xeppelin: big, heavy, clunky and1399 for a crop lens equivalent to 17-27mm FOV ... good luck selling this lens.

would really love to see detailed sales stats for such lenses. couple 100 units, globally?

This is probably the best UWA landscape lens for APS-C with the Fuji 8-16 (priced $2000). I purchased one and it is very sharp edge to edge and f/2.8 is very usable, it's not that big, well balanced on my K-3II, weather restistant, filter friendly, and HD coating is amazing to shot against the sun. I agree 1399€ is highly priced but I got mine for 1199€ and it worth its price. It is so much better than the old Pentax 12-24mm that I own too. This is the lens made to last many years.

zakaria: 11-18mm needs a new flagship Aps/c. I will not pay 1400£ for a lens to put it in Kp.

Honnestly, I don't think a new flagship will bring lot of IQ improvement for the 11-18 lens. The new flagship will probably improve AF, ergonomy, video, flash sync, fps, buffer... but there is no new super sensor around that will make your 100 ISO landscape better. May be they will use a 26MP sensor to replace the 24MP sensor of the KP but its no much difference.

TomCodyPleasedToMeetYa: I like Pentax and underdogs so I hope they survive. But I do feel they made a mistake with their FF DSLR. They should have moved into mirrorless APSC or FF and carved out their market like Fuji. Or they should have focused on smaller street cameras like the GR and medium format. It's hard to think of many people buying a new FF Pentax when the Nikon make the best DSLRs and there are so many mirrorless options now including medium format. I fear for their future.

I am sure they will release a mirrorless in the coming years but I am pretty sure they will keep the K-mount. If I were them, I would release an hybrid camera with two viewfinders: OVF and EVF :)

lili23: Pentax is dead. They have a lack of technology in these days that they can not make more new lenses like Sony.

My favorites Pentax features on my K3-II are:
- Composition adjustment to shift the sensor, very useful in cityscape to move the horizon on a third line while keeping the vertical lines perfectly straight. I also use it to shoot two frames or four frames and stitch them to make a panorama while keeping the camera in place. Useful is you need to include an element at the edge of the frame when you cannot zoom out more. Its a mini Shift lens, available to all lenses.
- Pixel shift resolution to bring tons of details in static subjects (rocks, building, etc...).

Probably not that bad for manufacturers as people switching to a smartphone are probably people that do not purchase any lens.

Not really a priority as I never found a faster photo editor... but every improvement is good to take :)
