All above shot with the lens on my Nikon D850.
The Nikon AF-P DX NIKKOR 10-20mm f/4.5-5.6G VR Lens is a remarkably good value lens for Nikon APS-C sensor cameras. It's all plastic, it's somewhat slow, but it's cheap and very light. It also works as a 14-20mm zoom on some "Full Frame" 35mm sensor cameras. Using it below 14mm leads to vignetting. Now, you CAN use it at 13mm and 12mm at a push if you are prepared to do some post-production editing, but at 14mm the edges and corners are clear, as you can see above.
You might ask the question, why use it when there are other genuine full-frame options available? Well the Nikon 14-28mm f/2.8 costs between £1200-1300 here in the UK and weighs 970g and the 10-20mm costs around the £250 mark and weighs 230g. So if you like using extreme wide-angle lenses and don't need the fast aperture or build quality of the 14-28mm the 10-20mm is a serious alternative. I bought mine S/H so it was even cheaper and I work outside in good light so it works fine for me.
Quality wise it's excellent, there is some softness in the corners, but that's a problem with most extreme wide angles anyway. It works particularly well with my Df, pictured above and it's great to carry around being so light. Below are some pictures shot with that combination.
So what can you use it on? Well, it works fine on my Df and D850 because I can choose what image size I want. I can select 'Full Frame' and use whatever lens I need to. However, it DOESN"T WORK on my Z7. Stick an APS-S lens on that camera and it automatically selects the APS-C crop and you can't change it. Now I hate cameras that do that. I don't like being told what to do at the best of times and my camera dictating how I use lenses really annoys me. However to be honest the APS-C crop on the Z7 produces a decent size file anyway, so I have used it on that camera.
These days, due to coronavirus, I have to be more circumspect about what I buy, since my library income is still not what it was before Covid and the 10-20mm suits me fine. I also love the lightness and compactness. And it does work well as you can see.
If want to see a full review from another enthusiast for the lens, Ken Rockwell has one of his usual forthright reviews at https://www.kenrockwell.com/nikon/10-20mm.htm. It was after reading this that I decided to buy the lens, so if you are interested it's well worth a read.
