Have any of you used it or seen any reviews? I am quite interested in this for my D810. At present my wide angle is the 14-24 works well but is large and heavy when travelling and with FX camera I rarely need more than 20mm. The new lens would take up much less room and at only 355g is light.
What are the results like? Or should I hold onto my old friend?

Graham,
I do not own either, but I have handled/used both on occasions.
On the recent 20mm 1.8.
I cannot see the use of a f 1.8 aperture, 2.8 would be enough for many people.
On the other hand, compared to the (famous) 14-24 the 20 1.8 is compact, light and more affordable.
Compared to most zoom lenses, distortion should be a lot less.
Regards, Gilbert

I have a 20mm f2.8 AFD and it is a superb lens for both visible and IR shooting, I also have the 17-35 f2.8 AFS so I think I am well covered.

I am sure the new lens has better handling of flare due to the newer coatings but I am very happy with my current lenses.

The f1.8 is not an issue for me as most of time when using this sort of lens I will be well stopped down. I need to know how good the lens in in terms of sharpness and distortion.

Graham,
re: sharpness and distortion.
I ahve not seen or done any tests.
Onthe basis that this is a new design, with the latest coatings, and not being a budget zoom-lens, it should satisfy the criteria you mention.
E.g. remember the distortion reported in the 16-35 f 4 lens of recent years.
Regards, Gilbert

If in doubt, hire one for a day or so on the understanding if you buy they refund some or all the hire charges.

I think Calumet do that, I know Fishwicks of Haydock used to, but sadly they are long gone.

I would have though that stopped down the lens should be excellent. I would be amazed if it wasn't. It isn't exactly a difficult focal length to get right, especially for a non zoom.

I have found several reviews now on the internet and reports look good for the new lens. I was impressed with how good one review said the flare from strong side or back light is greatly reduced.
The 14-24 is very prone to this type of flare and I think the greatly domed front of lens does not help. See attach pix taken a few weeks ago with D810 in strong side light that just caught the side of the lens at 14mm. I was able to spot the flare and retake the shot with my hand keeping sun off the lens.
I will try to have a test go with the new lens as the reduced size tempts me a lot!

I have had many such situations with the14-24...indoors with room setting lights as well as sunlight through windows or outdoors. This flare problem, its weight and the front glass vulnerability (I've scratched mine!) frequently cause me to dispense with it.

Now with full frame cameras for me 20mm is all I need. I hardly get to use use the 14-24 as it makes my camera bag too heavy. The new 20mm lens fits the bill for me.

Graham, had you seriously considered the Nikkor 2.8 20mm, it's an outstanding lens with minimal distortion.

My AFD version of this lens is very very sharp.

Current prices for the AFD version are £270ish.

Thanks for the help I had a 20mm f2.8 but traded it in with my 14mm when I got the 14-24 f2.8 AF-S perhaps mine was an also ran or an older model I found the Auto Focus poor with my then D2X, and sharpness only came in fully at f8.

I have now seen some good results from the new f1.8 20mm and have spoken to a friend who has one so I have now put in my order.

Lens arrive today light very poor but here is first image. Nikon 810 400 ISO 1/125 at f2.8. No distortion or colour fringing looks very sharp. Auto focus is very quick.

Grahsm,
Glad you like it
re: focus speed.
Consider that (as with most wide-angles) there is only a very small mass of glass to move during AF operation.
Compare that ea. to the latest 50 1.4 and 85 1.4 lenses, they are are labeled AF-S, but AF can feel slow due to the mass being moved.
Regards etc. Gilbert.

The compact size and just over 300g weight means you hardly notice it in the camera bag compared with the 14-24! Also since FX I find for my w/a needs 20mm is all I use!

Took a shot with my Sigma 12-24 at 20mm to compare. Distortion, twisting vertical lines inward.

Your Nikkor 20mm f1.8G ED pix shows good edge verticals.

Mike, I also have the Sigma 12-24mm but since it is a FF lens that 12mm is very very wide (and a little soft at the edges) but nice to have for those rare occasions.

We had a Green Christmas in Southern Ontario this year, not a flake of snow. Without 20 to 30 cm of snow there little outdoor recreation available for the holidays;~(
