Nikon High-Speed 50mm Lens Sharpness Comparison 09 Sep 2010
NEW: Premium 50mm Lenses Compared 04 September 2014
The new 50mm f/1.4 AF-S is a far better choice than any zoom for use in low light, and effectively quadruples your ISO, with no increase in noise, compared to any exotic f/2.8 zoom. The 50mm f/1.4 increases your ISO by ten times compared to any f/4.5 zoom, again with no change in noise.
Not for: It won't work on old manual focus cameras; see Nikon Lens Compatibility for details. Otherwise, immortal photographers like Henri Cartier-Bresson have never needed anything else than a single fixed 50mm lens.

Nikon 50mm f/1.4G. enlarge.
Nikon invented the world's first 50mm f/1.4 lens in 1950. This is Nikon's latest innovation for 2008, and their first new 50mm optical design in over 30 years.
My 50mm f/1.4 is the lens I use most often for photographing family and friends.
The reason you want this new 50mm f/1.4G AF-S instead of the perfectly good 50mm f/1.4 AF-D that Nikon has been making unchanged since 1993 is that you can tweak manual focus simply by touching the ring. With the older AF-D lens, you have to move a switch on the camera to get between manual and auto focus.
When this AF-S lens autofocuses, nothing moves except the glass inside the solid barrel. The focus ring and filter ring don't move. It you get hit with a thrown bottle or rock, you won't likely mess up the delicate internal focus mechanics.
By comparison, you have to keep your fingers away from the focus ring of the old AF-D lens, since it has to be left alone to spin freely while the lens autofocuses. When you bang the front of the AF-D lens on a rock, you can screw up the alignment because the entire front of the old lens moves in and out on a helicoid.
The only gotchas are that this new lens has more barrel distortion than the old 50mm f/1.4 AF-D, it has a weird 58mm (not standard 52mm) filter size, and that this new lens is useless on Nikons made before about 1990.
This new Nikon lens uses an 8 element design, while every other 50mm f/1.4 SLR lens from Nikon, Canon and Zeiss has only had 7 elements for decades. The close-focus distance is the same, at 1.5 feet (0.45meters).
In formal, controlled tests this new lens isn't any sharper than all the other very sharp 50mm f/1.4 lenses Nikon has made these past decades, but in real photos where autofocus accuracy and hit rate matter, the results at f/1.4 are even better than older lenses. I'm getting sharp, haze-free shots dead-on in-focus at f/1.4 on all of my cameras, where at f/1.4 my old 50/1.4 AF-D often had more veil, bloom or glow (what scientists call spherical aberration) in real shots.
This new 50 wins on subtlety for real things you shoot with a fast 50mm, but doesn't do anything different in tests for flat subjects at infinity.
If you need f/1.4 at a lower price, get the older and perfectly great 50mm f/1.4 AF-D instead.
Besides being Nikon's first fast AF lens that actually can autofocus on the D40, D40x or D60, what makes this new 50 1.4 stand out is how well it works in actual shooting, as opposed to lab tests. In chasing around moving targets, even at f/1.4 I consistently get fantastic, sharp, in-focus results.
Trying to make what seem like simple shots like this with the Canon 5D Mark II and Canon's 50/1.4 USM just don't do this, because I can't get an AF sensor where I want it, and the Canon system can't nail every shot like this Nikon combo does. What you don't want to see is that almost all of the 100 other snaps were also in focus at f/1.4, even if Ryan wasn't smiling. At f/1.4, the depth-of-field is only about an inch, and remember, this kid was moving, not waiting for dad to snap his photo.
Complain about kid pictures all you want, but unlike shooting Formula One racing or American hero Lance Armstrong, you don't know where the kid is going next. Just try getting an in-focus shot without AF.

The incompatibilities for older or cheaper film cameras are that:
1.) It won't autofocus with the cheapest new AF film cameras like the N55, but if you focus manually, everything else works great. Even if you lose autofocus, these cameras have in-finder focus confirmation dots to help you.
2.) Late 1980s ~ early 1990s AF cameras like the N90s, N70 and F4 will focus just fine. You'll have Program and Shutter-priority modes, but lose Manual and Aperture-priority since you have no way to set the aperture on the camera or on the lens.
3.) You're really pushing it with the oldest AF cameras like the N2020, N6006 and N8008. You'll have no AF, confused exposure modes and confused metering. Manual focus is fine, along with electronic focus indications.
4.) Since it has no aperture ring, it's just about useless with manual focus film cameras.
See Nikon Lens Compatibility for details with your camera. Read down the "AF-S, AF-I," and "G"columns for this lens. You'll get the least of all the features displayed in all columns, since "G" (gelding) is a handicap which removes features.
1933: Nikon, formed in 1917 out of three other companies around since the 1800s, makes the first Nikkor lens. This new 50mm lens commemorates the 75th anniversary of Nikkor lenses.
1935: Canon's very first camera, the Hansa Kwanon, used a Nikkor lens. Canon didn't make lenses in the 1930s and 1940s, and instead got them from Nikon. Nikon didn't make cameras until the late 1940s, so no problem.
1945 Canon S Rangefinder with 50mm f/3.5 Nikkor lens, as shown in Canon's historical display in their booth at PMA 2007.
The world's fastest lens ever in 35mm photography, the Nikon Nikkor-S 5cm f/1.4 trumped the Zeiss 5cm f/1.5 for use on rangefinder cameras. This Nikkor has 7 elements condensed into only 3 groups to reduce flare and ghosts. Its performance is OK, but not as good as modern 50mm lenses. I suspect the f/2 version of this rangefinder lens was better, but have never tried it.
Nikon's first f/1.4 SLR lens was the 7 element, 6 group, Nikon 58mm f/1.4. If you have it converted in a machine shop, it still works fine on the D700 and D3. It has low contrast and a dreamy, hazy effect shot at f/1.4, and is super-sharp stopped down.
Nikon updates the design of the popular 50mm f/1.4 to 7 elements and 6 groups, and the mechanics to AI. This same design is sold today as the 50mm f/1.4 AF-D and the still-in-production manual focus 50mm f/1.4 AI-s, which you still can buy brand-new at B&H Photo-Video for about $300.
The first new optical design since 1976, this 50mm f/1.4 AF-S is the first 50mm f/1.4 lens from Nikon to use an 8 element design. (Leica's 50mm f/1.4 ASPH also uses 8 elements, as well as aspherics and floating elements, far beyond Nikon, but ten times as expensive, too.)

Box, Nikon 50mm f1.4 AFS
Optical performance oddly is the same as older designs, but with more distortion. Oh well.
AF performance and ergonomics are finally up to date over all the other old mechanical focusing 50mm Nikon lenses.
What makes this new lens stand out are its superior ergonomics, and its superb ability to get every shot in perfect focus, so long a you're using your camera properly.
Nothing moves externally when focused, except of course the focus ring, but only if you touch it.
AF tracks moving subjects just fine.
AF is very accurate and repeatable, much better than Canon. Even on a D40, I can shoot at f/1.4 and get every shot in perfect focus. Just try this with a manual focus camera; I never could get results this good.
Manual focus is easy: just grab the ring at any time.
M/A - M Switch
Nikon goofed. This switch is supposed to be labeled "A - M."
The "M/A" position means autofocus. It's called "M/A" because back in the old days, when Nikon had almost caught up to Canon who had been doing this for ten years before, Nikon was trying to show off that you could focus manually while in the AF position.
Paint over the extra M if you're easily confused.
At f/1.4 on FX, Nikon 50/1.4G. enlarge.
Bokeh, the character of out of focus backgrounds, not simply how far out of focus they are, is very, very good.
It's also very good for foregrounds, but you should never have out of focus foregrounds unless you have a very good reason; our eyes and brains freak out when there's something fuzzy between us and the subject.
The 9-bladed diaphragm gives essentially round circles at every aperture, unlike previous Nikon 50mm f/1.4 SLR lenses whose 7-bladed diaphragms could give septagonal blur circles.
I can't see any difference in color rendition between this 50 1.4 AFS and my other multicoated AF lenses.
Coma (saggital coma flare) is weird smeared blobs that appear around bright points of light in the corners. They happen with fast and wide lenses at large apertures. Coma goes away as stopped down, and tends not to be seen in slower and tele lenses.
The 50mm AFS has coma at f/1.4, which becomes weaker as stopped down, but isn't completely gone until f/4.
The 50mm f/1.4 AF-S has relatively strong and visible barrel (bulging) distortion.
It's plainly visible, so if straight lines and architectural items are your thing, pass on this lens and get the 50mm f/1.4 AF-D instead , or get the 50mm f/1.8 AF-D which has no distortion at all and sells new for only $110.
The distortion of this 50/1.4G easily can be corrected for critical use by plugging these figures into Photoshop CS2's lens distortion filter. These aren't facts or specifications, they are the results of my research that requires hours of photography and calculations on the resulting data.

Ergonomics are superb. Ergonomics are the reason to get this 50/1.4G instead of the earlier ones.
The focus ring doesn't move during AF; it only moves when you turn it for instant manual focus override.
It seems silly, but you can just hold the outside of this lens and shoot. With every other NIkon AF 50mm made to date, you have to avoid touching the focus ring, because it moves as the lens autofocuses. If you touch the ring of the other lenses, you bung up the focus, with this 50/1.4, no problem: hold on tight anywhere you want.
Falloff on FX is as expected: visible at f/1.4, barely visible at f/2, and gone by f/2.8. If you're shooting tests and looking for it explicitly by comparison to other apertures, it's completely gone by f/4.
I've exaggerated this by shooting a gray field and placing these on a gray background.
There is no problem with vignetting, even with combinations of thick filters.
The filter ring never rotates. It never moves in and out, either.
You'll probably go blind trying to see any ghosts. Good luck, I can't make any happen under any reasonable set of conditions.
Nikon 50/1.4G with included BH-47 Hood. enlarge.
The plastic bayonet hood is dinky.
I wouldn't use it; I'd rather just shield the lens with my hand if I need it so I don't have to worry about breaking the hood the first time I use it.
I can't see any lateral color fringes on the D3 or D40. The D3 would correct them if the lens had any.
The 50G feels just like the 18-200mm VR and similar lenses.
Hood: Dinky plastic bayonet, included.
Barrel Exterior: Plastic.
Filter Threads: Plastic.
Hood Mount: Plastic.
Focus Ring: Plastic; rubber covered.
Focus Helicoids: Beats me. Feels like semi-gritty plastic.
Depth-of-Field Scale: Barely.
Internals: Who knows, probably some metal and lots of plastic. Diaphragm blades seem like metal.
Aperture Ring: None.
Mount: Seems like the usual dull-chromed brass.
Identity Plate: Raise gold letters, looks like metal and feels like plastic.
Serial Number: Printed sticker on bottom of barrel.
Ass-Gasket (dust seal at mount): Yes.
Noises When Shaken: Clicking and klunking.
Made in: Red China. Get over it, both AF-D 50mm lenses are made there, too.
With those caveats, the 50mm f/1.4 AF-S is at least as sharp as every other 50/1.4 at most apertures, and significantly better shot wide-open at f/1.4.
On a D3 (12MP FX) at infinity:
At f/1.4: The 50mm f/1.4G AF-S is sharp all over, but has lower contrast in the corners of FX due to coma (slight radial blurring of highlights). The spherical aberration in the center isn't much of a problem, so most of the image is sharp and contrasty without much veiling, fog or haze, also called glow or bloom by Leicaphiles.
At f/2: Contrast picks up from the lessening of spherical aberration in the center. Far corners on FX are a little better than at f/1.4.
At f/2.8: Much better in the corners of FX.
At f/4: Better still, and still getting better in the corners of FX.
At f/5.6: The only improvement is the very far corners of FX. f/5.6 is optimum.
At f/8: Same as f/5.6.
At f/11: Almost as good as f/8.
At f/16: Softer due to Diffraction.
Spherochromatism is the variation of spherical aberration with color. This is what causes out-of focus highlights to have slight color fringes, typically green and magenta, with fast normal and long lenses.
This 50/1.4G has some, meaning that at f/1.4 your background highlights might have a bit of green or bluish-green around them. Well-composed photos shouldn't have out-of-focus foreground elements, but of you do at f/1.4, they may have slight magenta to reddish-magenta fringes.
You won't notice this unless you look for it, and like many artifacts, once you notice it, you'll always see it, so don't look for it!
It's hard to get sunstars because the diaphragm is so round.
If you can, they tend to be asymmetrical, mostly due to whatever slight out-of-roundness you get in the 9-bladed diaphragm.
I'd prefer a straight 9-bladed diaphragm instead of the rounded blades, which would give stronger, more precise sunstars.
NEW: Premium 50mm Lenses Compared 04 September 2014
Want easy switching to manual focus? This is Nikon's best lens by far; just grab the ring at any time.
Oddly, optical quality is the same as other 50/1.4s, but distortion is worse.
Want to use it on a manual-focus camera? Forget it; you can't control the aperture. Use any manual focus lens for best feel and results.
A 50mm f/1.4 is mandatory for anyone shooting in available light. The older AF-D works great on all the cameras likely to be used by serious photographers, but you were out of luck with the D40, D40x or D60.
This new 50mm gives even clearer results for real-world available-light portraiture at f/1.4 than the older lenses, and it doesn't chatter away in AF-C mode as do the older mechanically focused (AF and AF-D) 50mm and 85mm lenses. All these lenses are equally sharp by f/2.8.
If price matters, the old 50/1.4 AF-D is still excellent. The biggest disadvantage is having to keep your hands away from the old 50mm's focus ring as it moves by itself in AF mode.
If you worry about straight lines or distortion, this is the worse 50mm lens ever made by Nikon since at least 1950, and I've tried them all, even for their rangefinder cameras. For low distortion, any of the f/1.8 lenses are nearly perfect. The 50mm f/2 and other f/1.4 lenses are all better than this 50/1.4G. The 50mm f/1.2 (only made for pros, so it's manual-focus only) is about the same, but still has a a hair less distortion than this 50/1.4 AF-S.
Enough of my bellyaching. This AF-S lens rules for real shooting. Shoot it in the dark, and the images are sharp, and dead-on in-focus with any of the cameras I've tried. With an f/1.4 lens, being in focus is critical, and this new lens excels at real-world performance.
I love mine, and I will be making most of my Christmas and family pictures with it from now on.
Capped Nikon 50/1.4 AFS. enlarge.
I never use hoods. I'd leave it in the box.
If I was going to use this as part of a larger pro system, I'd consider attaching a 58->77mm step-up-ring to convert this to today's pro standard of 77mm, and use a 77mm Nikon UV or Hoya UV filter for protection. This is what I really do; I just put on a step-up ring when I get a lens like this and treat it as if it's a 77mm filter thread len as long as I have it. I'd get a new "pinch" type cap in 77mm too.
