How to Use Ultrawide Lenses

Why Fixed Lenses Take Better Pictures

 

Sharpness Comparison to all other 18mm lenses 11 August 2010

 

Ideal Uses: Perfect for use on FX digital and film.

Not for: I wouldn't bother with this on a DX camera. I'd use any DX lens, like the 18-55mm AF-P kit lens, for better results on DX.

I buy only from these approved sources. I can't vouch for ads below.

This Nikon 18mm f/2.8 AF-D lens is very rare because it has always been an expensive professional lens. Few people bought it when new because it cost over $1,000 in its day, and it wasn't much different in performance than the 20mm f/2.8 AF-D which did pretty much the same thing in a smaller, lighter, plasticier package for less than half the price. The 20mm is still available new today, while this exotic professional 18mm was discontinued in 2006.

Nikon only sold about 7,500 of these 18mm lenses, while it's sold about a quarter-million 20mm f/2.8 AF, and still makes the 20/2.8 today. Zooms are even more popular: Nikon sold 50,000 of the 20-35mm, 140,000 of the 17-35mm as of 2017 and still sells them, 110,000 of the 18-35mm and 350,000 of the 14-24mm, so far.

This 18mm excels at being the widest possible Nikon autofocus lens in the smallest, toughest package. All the Nikon wide zooms are much bigger and heavier, and the spectacular but plasticy 20mm f/1.8G is also bigger and heavier.

This 18mm is expensive because it's a tough, professional lens and even uses an aspherical element, a first in its day along with the incomparable Nikon 28mm f/1.4 AF-D. The 28mm has a precision ground aspherical element, while this 18mm has a molded one.

This 18mm is sharper in the center at wide apertures than the 20mm f/2.8 AF.

The 20mm f/1.8G is all plastic and weighs less than this 18mm, but is a bit bigger.

The newest 20mm f/1.8G is by far the sharpest of any Nikon 13mm, 14mm, 15mm, 18mm or 20mm fixed lens.

Unlike the less expensive 20/2.8, this 18mm comes in a nice fitted tubular case with an HB-8 hood.

When using this 18mm AF lens, be sure to keep your fingers away from the focus ring, which turns anytime the camera attempts to autofocus. There is no way to disengage it.

The 18mm f/2.8 AF-D has the same tough build and styling as the 28mm F/1.4D AF, 20-35mm f/2.8D AF and 85mm f/1.4D AF, which means a nice metal filter thread. The only plastic is the AF window and the aperture ring. This 18mm is much tougher than any of the current Nikon ultrawides and about s tough as the ancient 17-35/2.8 that Nikon still sells today.

Nikon's newer FX cameras, like my D850, easily correct this lens' complex distortions.

 

Compatibility       back to intro     back to top

The 18mm f/2.8 AF-D works great with almost every film and digital Nikon camera made since 1977. If you have a coupling prong added to the diaphragm ring, it's perfect with every Nikon back to the original Nikon F of 1959.

The only incompatibility is that it will not autofocus with the cheapest DX cameras like the D40, D40x, D60, D3000 or D5000, but if you focus manually, everything else works great. These cameras have in-finder focus confirmation dots to help you.

See Nikon Lens Compatibility for details on your camera. Read down the "AF, AF-D (screw)" column for this lens.

Performance         top

Sample Images   Intro   Specifications

Performance   Recommendations

Performance is certainly usable, but unfortunately for the price, almost identical to or slightly worse than the smaller and less expensive 20mm f/2.8 AF.

That's why I put this 18mm lens in Nikon's 10 Worst Lenses: because it works well enough, but really ought to be better for the price.

If you're looking in the corners closely for sharpness, you need to get the 14-24mm or 16-35mm VR instead for FX cameras.

 

Autofocus

AF speed is very fast.

One full turn of the AF screw focuses the lens from infinity to 1.5.' Whew, that's fast!

 

Focus Breathing

Focus breathing is the image changing size as focused in and out. It's important to cinematographers because it looks funny if the image changes size as focus gets pulled back and forth between actors. If the lens does this, the image "breathes" by growing and contracting slightly as the dialog goes back and forth.

The image from this Nikon 18 2.8 gets only very slightly smaller as focussed more closely; you'll never see it in any actual use.

 

Color Balance

Color balance was a point or two cooler than the 20/2.8, probably not enough to ever notice.

 

Distortion

Distortion is complex. Here's the horizon on FX:

Photoshop CS2's lens distortion filter is of no use to correct this complex distortion on FX, however on DX you can correct the barrel distortion with these figures:

Ergonomics

This is a very standard lens with no surprises.

Be sure to keep your hand off the focus ring during autofocus.

Manual focus feels nicer than most AF lenses, but be sure to set your camera to M before turning the ring.

 

Falloff (darkened corners)    back to performance     back to top

Falloff on FX is plenty wide open, and not a problem stopped down.

It won't be an issue at all on DX (see crop factor).

I've exaggerated this by shooting a gray field and placing these on a gray background.

Filters, use with

There is no vignetting on FX with one filter.

Forget trying to use two filters at the same time.

Any vignetting gets worse at f/16.

Any vignetting gets a tiny bit worse at closer focus distances.

 

Flare and Ghosts

It has lots of little ghosts; worse than the 20/2.8 AF.

You need to use the obnoxious hood included, unlike with the 20mm AF whose hood you don't need.

 

Focus Breathing

As you pull focus in and out, the barrel distortion gets stronger as you pull in focus.

 

Mechanics and Construction

rear, 18 2.8

Rear, Nikon 18 2.8. enlarge.

 

Filter Threads and Hood Bayonet

Black painted aluminum on first version, black anodized on later (s/n starting with 4). The bayonet seems precision cast on earlier models and machined on latter models, unless the paint is hiding the machining marks on the earlier models. I could be wrong and they all may be one way or another, but I do know they are all metal.

 

Focus Ring

Rubber-covered metal.

 

Barrel

Plastic and metal, black crinkle-coat paint.

 

Aperture Ring

Plastic.

 

Markings

Paint.

 

Switches

One sliding plastic aperture ring lock.

 

Mount

Dull chromed brass.

 

Internals

I see metal.

 

Noises when shaken

One klunk on early version (s/n starting in 2) and maybe one slight click on latter version (s/n starting in 4).

 

Serial Number

Burnt into bottom rear of plastic aperture ring.

 

Made in

Japan.

 

Sharpness

It is a bit sharper than the 20/2.8 AF wide open, but never gets perfectly sharp in the corners at any aperture.

The only SLR lens significantly better than all these is Nikon's newest 16-35mm and 14-24mm. The 14-24mm weighs three times as much and can't use filters for creative effects or for protection.

If you really need a sharp 18mm lens, also consider the the LEICA 18mm or Zeiss 18mm for LEICA M rangefinder cameras.

 

Recommendations         top

Sample Images   Intro   Specifications

Performance   Recommendations

I use this lens along with my 28-300mm rather than carry my much bigger 16-35mm VR. I prefer it to my 20/1.8 because it's wider; if I'm getting 28mm with my 28-300, I want something wider than 20mm if I'm carrying another lens.

Get one of these if toughness and light weight are important. I'm all about light weight, thus this lens is a favorite. It's the toughest autofocus ultrawide fixed lens ever made by Nikon.

If you want similar optical performance for less money, try the 20mm f/2.8 AF. The 20/2.8 has better ghost performance and the same sharpness and distortion performance as this far more expensive 18/2.8D AF. I still prefer this tougher 18mm for its wider view and standard 77mm filter size.

If you want to spend more money and get better performance, get the 17-35mm f/2.8D AF-S (almost as tough mechanically and better optically) or the 16-35mm VR (big and plastic, but much better optically).
