20mm f1.8G

Check out the Samyang 14, very sharp, inexpensive, manual focus with focus confirm. I will get the Nikon AF 20mm f/1.8, but will probably keep the Samyang 14mm MF for extra wide landscapes.
Samyang makes some outstanding lenses but 14mm is bit wider than I need, really... That and I rarely, if ever, use wide-angle lenses for landscapes.

Hi, Horoscope Fish,
If you "rarely use wide-angle lenses for landscapes" and "20mm is way off", what do you use other than the obvious Sigma Art 35mm?

When I said the 20mm was "a ways off" I just meant it's going to be a little while before I can spend the money for one. I think it looks like an awesome lens, and it's now officially "on the list", but it's going to have to wait for now.

I not only enjoy the 14mm for the wide and sharpness but also for the distortion. I always have distortion correction disabled in my cam in order to see exactly what happens and do like this lens because I can push my shot towards a certain movement (or feeling) when tilting it at close range.

I think this is the lens profile the other mentions in his post and which he combined with the Canon one to get his version. I'm going to download it anyways to check which of both works best for me.

While going somewhere this morning I walked past the photo-store and completely against my will someone must have pushed me inside and then forced me to order the Samyang 24mm 1.4.

At least that's how I like to remember it.

If the 20mm turns out to be a gem, maybe I'll get forced to order that one too.

It seems delivery of the new Nikon 20mm f/1.8 has stopped.
Nikon rarely talks about their problems, and Nikon Rumors has not mentioned it.
Has anybody heard anything ?

That's going to be a very popular lens and the fact it's back-ordered does not surprise me.

It doesn't indicate a problem.

LenScore is out. They rate the 20mm f/1.8 in comparison to the Nikon 85mm f/1.4 which scores 1000 on all points.

20mm f/1.8 Resolution: 928
20mm f/1.8 Total score: 855

Their Comment:
Distinctly uneven performance across the frame with great resolving power and contrast in the center and mediocre to poor corner performance that doesn't improve much on stopping down. This somewhat diminishes this lightweight super wide prime's potential for fine art landscape photography, but it's still a good value and certainly a welcome addition to the Nikkor family.


LenScore™ Digital Camera Lens Rating

My comment:
I wish LenScore would be a bit more detailed in their report. I like the way they test all lenses on the same 2000MP sensor, but I wish they would offer a more detailed report alá DxO with graphs of for example center resolution to corner resolution instead of just one value.

Well.... it goes without saying that it's a "good" lens... but maybe not a "great" lens.
Typical of Nikon glass, IMO.

And whenever I read the phrase, "good value" it gives me significant pause. While I admit there are notable exceptions, to me that sounds like code for "this is a mediocre lens but they're not taking you out behind the wood shed and anally raping you, price-wise, so it's got that going for it!"

The shot I've seen here taken with the 20mm was pretty good. I think there is a review out there done by hmm... that dude with the Eastern-European name.

It's maybe a good thing I picked the Samyang. I'm not too impressed with the lens correction I'm using now but the color/contrast and sharpness I find it a good enough bargain for.

I'm not too impressed with the (Samyang 14) lens correction I'm using now ...
I presently correct it manually in Lightroom and Photoshop. I hope for a Lightroom update to include the correction.
I have cross referenced LenScore data for the new Nikon 20mm f/1.8 to older lenses. It compares very closely to the Nikon 28 f/1.8 which has a DxO score of 36/28 while it surpasses the Samyang 14 DxO score of 27/27. In other words, overall IQ score of the Nikon 20 is substantially better than the Samyang 14 while sharpness is about the same.

I was talking about the lens correction of the 24mm. The 14mm correction is better. The 24 doesn't seem to do a good job for the 750 and I need to manually adjust too often.

I didn't check the lens score at Lenscore because the data is nonsensical to me. It's a score based upon a test that has as much to do with my cam/lens combination as me switching off my refrigerator has something to do with my cam's buffer. I wouldn't know what to do with their scoring system. It's like me saying to you the lens is a 7.

I've shot both now and at the aperture I'm using them they're at least as sharp as my 200mm. Considering I already managed to ruin my pod during the nights, I'm going to stick with the cheaper options for lenses. Sooner or later one of them is going to get into trouble too.

It's possible the 20mm is sharper, I'm not saying anything about that. Too bad DxO is seriously slacking. It's more than a month since they added anything.

Mansurov or something is the guy's name. I just remember it.

Agreed,
LenScore tests all lenses with the same 200 MP sensor. It gives you quick data for the relative performance of a lens. For me it's enough to decide whether to wait for DxO data or not.
DxO tests lenses on specific cameras. They give you much more specific data but it takes them a lot of time.
P.S. The data from the two test houses correlate quite well except for lenses over 400mm where data from DxO does NOT support the seemingly exceedingly favorable data from LenScore.
