5One of the best lens for portrait and low light photography. Please check if your camera require AF-S lens instead
By Sidarta Tanu
I don't even know where to start. This lens produces sharp pictures and great color and contrast. And for its price (which seems to climb recently), it is worth more than 5 stars rating. I initially get this lens for low light action and sport photography (as this lens is famous for being one of the fastest lens together with its brother 50mm f/1.4), but I also found out that this lens is also perfect for portrait and other general purposes (macro etc). This is definitely a very versatile lens.

It is important to note that you will need camera with internal AF motor (D90, D300, D600, D700, D800, D7000, etc) for this AF lens autofocus to work properly. If your camera is D40/D60/D3000/D5000 series (no internal AF motor), you will need to get the AF-S type lens, otherwise if you get this AF lens, only the manual focus will be available to you.

And as much as I want to encourage everyone to buy this lens right away, let me mention some of the limitation that you would see (which I think will be helpful to go over before deciding to buy this lens):

First, being a prime lens, you will need to move your feet a lot to compose your picture. If you are used to zoom lens, don't underestimate this limitation. It takes me a while to get used to it, and sometime I still find people looking at me wondering why I am moving forward and backwards. the good news is that most of the time, they don't think I'm weird, but they are actually wondering if I'm a professional photographer.

Secondly, the focal range of 50mm, which is considered the normal lens and great for portrait lens. but on many DSLRs which is not full frame (unless you have a full frame Nikon DSLR like the D700 or D3, then 50mm is 50mm), this lens become a 75mm equivalent which is in the border of a short tele lens. I actually like the 75mm equivalent though I often have to move backwards when taking picture of a group of people.

Third, in some situation the autofocus might not able to focus (which is common for many other lens too). It is hard for the autofocus to lock when aiming at a wall that is one color (usually black or white), or on a clear sky (day or night). This kind of makes sense to me actually. IN these situations the AF assist light doesn't help either so you can opt for manual focus or set the focus to infinity when you can't find focus lock on scenic/landscape or sky photography. So far I don't have many problems with the autofocus.

Sharpness increases as you stop down to f/2.2 or f/2.5. I actually use f/1.8 most of the time and the results are still nice. Personally, I'd rather use f/1.8 aperture settings than stopped down (e.g to f/2.8) and compensate with higher ISO setting which often gives me grainy picture. But if your object is not moving (static) then it is better to stop down to f/2.8 or more.

If you are wondering whether you should get a fast lens or a lens with VR (Vibration Reduction), here's my take: In overall, VR does help a lot (as it will reduce camera shake) and will produce better/sharper picture than equivalent lens without VR (especially if the object is static). If the object is moving (sports/action) then VR feature alone might not help (depending on how fast the object is moving and how much light is available), and a fast lens often end up being a far better solution, even without VR feature as it will allow much faster shutter speed to freeze motion. Using tripod (and a remote) will substitute for the need of VR feature. In general I would recommend getting a fast lens with VR feature (and usually it is expensive) such as the 70-200 f/2.8 VR, but if one can only get for one or the other, then find out what do you want to use the lens for and then use the guideline mentioned here.

If you are wondering whether you will get the benefit of buying f/1.4 lens over a f/1.8 lens, just remember that the f/1.4 lens is about 60% faster than f/1.8 at its widest aperture setting. With this information, you can decide if the additional speed will justify the additional cost. The bokeh is nicer as well in f/1.4 lens but I think speed is usually the main factor in deciding whether to get the more expensive f/1.4 lens.

Here are the summary of pros and cons for this Nikon 50mm f/1.8D AF lens:

Pros:
1. Very fast (f/1.8)
2. Very sharp pictures (especially when stopped down to f/2.2, f/2.5 or more.)
3. Great for sport/action photography
4. Great for indoor and low light situation
5. Great for portrait
6. Bokeh is almost as good as many expensive Nikon tele-lens
7. Fast autofocus
8. Good for wedding photography (or no-flash event). However, if this is your main objective then you might want to get the 50mm f/1.4 version or 28-70mm f/2.8 lens)
9. 75mm equivalent which can be considered a short tele lens (I actually like the fact that it's 75mm equivalent vs 50mm in DSLR. if you need more zoom, you can get the Nikon 85mm f/1.8, or the 70-200mm f/2.8 VR). If you have full frame DSLR(like the D3 or D700), then this #9 pros is not applicable.
10. Inexpensive

Cons:
1. Being prime lens, you need to move your feet a lot to adjust/compose
2. Autofocus issue on some situations (read detail above)
3. Plasticy build
4. Autofocus is not the most silent but very reasonable
5. 75mm equivalent with 1.5x multiplier on non full frame DSLR (many people find this is an odd range for normal lens. I actually like it). If you have full frame DSLR(like the D3 or D700), then this #5 cons is not applicable.
6. Autofocus does not work with D40, D40x, D60, D3000, D3100, D3200, D5000, D5100, D5200 etc (basicaly D40/D60/D3000/D5000 series. it's best to check if your camera body require AF-S lens). The newer 50mm f/1.8G AF-S, 50mm f/1.4G AF-S lens or 35mm f/1.8G AF-S lens will autofocus with those cameras.

Bottom line: This lens is so versatile (and inexpensive) that I think everyone should own in addition to all the lenses that they already have. Being a very fast lens, it enables me to take pictures in low light (sport/action photography) that I otherwise wouldn't be able to do.
After knowing its limitation, I would predict that 99% of you that decides to buy this lens will find this lens very useful. And if you decide that you don't like it (which I think not more than 1%), I'm sure there will be a lot of people who wouldn't mind buying it from you (with some discount of course).

Again, I would recommend everyone to get this lens. In some ways I can say that this lens makes me a better photographer.

Happy Photographing!

5Dollar for dollar the best buy in a bright sharp lens
By Albert J. Valentino
This lens is probably the sharpest lens that Nikon makes--see lens reviews/specs at [...] I use this lens for low light situations outdoors and indoors so I don't need a flash. also, small dept-of-field. Using this at f/2.0 I will get at least four-six times as much light (which means four-six times faster shutter speed) as my zoom at around f/4.8 and also have a sharper image. For $99.00 this f/1.8 is a steal and a much better buy than the f/1.4 which is almost as sharp a lens and costs about $250.00--it's a no brainer.

I use this with my Nikon D70--remember, with a digital SLR this is equivalent to a 75mm lens for film which it a pretty good portrait lens.

Just buy it--for the price you can't go wrong.

3Possibly a bad sample?
By Glenn Carpenter
I was surprised to find, after reading so many positive reviews of this lens, that the copy I received was so fuzzy at wide-open apertures that I could see it on UN-MAGNIFIED images right on my D90's 3" screen.

All lenses lose sharpness at wide apertures: this is a matter of basic physics and is the result of something called spherical aberration. Some are much better than others though, thanks to better optical designs that more effectively correct for this tendency. The 35mm f/2, for example, is very good wide open; the 85mm f/1.8 is decent (and very appropriate for portrait use). My copy of the 50mm f/1.8 lost both sharpness and significant contrast as f/1.8 was approached. I would quantify it as follows:

f/1.8: very fuzzy (well beyond "soft"), reduced contrast, almost un-useable
f/2.8: still quite soft, much improved contrast
f/4: slightly soft, good contrast
f/5.6: sharp, good contrast
f/8: very sharp, good contrast

These results were repeatable on my sample and held true regardless of shutter speed and technique.

Notes:

- The advantage of a lens like this is the ability to use wide apertures. A good portrait lens need not be particularly sharp, but wider than f/4 my copy of this lens was soft enough that I would use it for nothing other than casual people-photography. It would not suffice for critical night or low-light photography, or for general photography where sharpness might be desired. For photos of people it was fine at f/2.8, but below that it lost so much sharpness, and enough contrast, that photos of almost any subject looked dull.

- The lens seems like an obvious choice as a first prime due to its price and the many excellent reviews of it here on Amazon and elsewhere. Even besides the sharpness degradation wide open, I found it less useful than I'd hoped. On a crop-size DSLR, it is a short telephoto lens, and it just hasn't turned out to be a focal length I use all that much. I would urge potential buyers to consider the 35mm f/2 before this lens as it gives the traditional "normal" perspective on a Nikon crop-size DSLR.

- Some reviewers like this lens for portrait use, but again, I found it poorly suited for this. The 85mm f/1.8 is admittedly more expensive, but it has far more potential as a portrait lens.

- This is not a high-contrast lens. It does not use any ED glass elements, which seem to be quite magical at improving contrast, and color rendition is noticeably less vibrant than such lenses. For some types of photography this can actually be desirable, but for general or landscape photography I prefer the higher-contrast lenses.

- My sample of this lens may have been below average, considering that most reviews of the lens are very positive. However, if you read carefully, most thorough reviews do mention that it loses contrast and acuity at wide apertures. Ken Rockwell, for example, has reviewed the lens very positively, but when it came time to suggest lenses sharp enough to be used on the new D3x, with its ultra-high-resolution sensor, he gave the similar-performing (possibly better) f/1.4 "G" version only three stars. I would submit that it is really not quite as sharp a lens as its reputation would lead one to believe. My excellent 16-85mm DX zoom, for example (the only lens I've given a five-star review as of this time), is far sharper than this lens up to around f/8 and hold an edge even there and beyond.

- Nikon has recently announced a new 35mm f/1.8 DX lens. I've ordered one and will probably post a review once I've had a chance to use it. I would suggest that it is very likely to be a better choice than this lens for almost any DX user. Being designed for the smaller DX sensor, it will probably be optimized for high linear resolutions within the smaller DX image circle. It is also a fairly inexpensive lens, not much more than this lens now that the 50mm has crept up a bit in price.

- Even if my sample is significantly poorer than average, my experience indicates that it would be a good idea to thoroughly test a copy of this lens before committing to buy it. Be sure to compare images at wide apertures to those made at f/8, where sharpness should be very good, and determine for yourself whether the loss of sharpness and contrast is acceptable for your purposes.

- Focus is plenty quick and accurate, at least on my sample. No problems at all in this regard (and none expected).

5Don't believe the reviews!
By Mark J. Sebastian
The reviews of the 50mm f/1.2L are useless. All you hear is "Spend your money on the 35L or 85L instead" or "the focusing issues make this lens unuseable". But something makes me think that people are just writing reviews based on what other people have said without actually ever using the product.

If you ever want to shoot snapshots of downtown without a flash at midnight WHILE walking, this is the lens to have. I'm so in love with this lens.

Pros:
* It's completely silent. Quieter than the f/1.4
* It has no problems focusing in the dark
* It's highly useable at f1.2
* It's sharper than the f/1.4
* Colors are more saturated than the f/1.4
* Images taken with this lens have higher contrast than the f/1.4
* It makes the f/1.4 feel like a hunk of plastic
* It comes with a hood

Cons:
* It costs 4 times more than the f/1.4
* It costs 18 times more than the f/1.8

Pros:
* You can comfortably shoot under conditions that would make the f/1.4 nervous.
* Produces a much higher yield of useable photos
* Aesthetically, it's the coolest looking lens I own!

For those who are concerned about the "back focusing" issue, I will let you know that I haven't experienced any backfocusing at all. I've let others shoot with it, wide open, within low-light environments and even the non-photographers were able to focus/shoot accurately.

This is my review from my non-scientific, real-world, situational testing.

5Don't be scared. It is good lens.
By Dong W. Kim
I am not a professional photographer, or make living with taking pictures. I am just a person who loves to take pictures & enjoys good pictures. And, I know how expensive this lens is, and YES, I am very aware of "Back Focusing" issue with this lens that others worry. I have been using this lens for 3 weeks now, and have been experiencing good & bad about this lens. (I believe "back focusing" issue was way too much inflated.) I have EOS 5D, and wanted to take full advantage of FF factor, and this was why I took a plunge instead of getting acclaimed 35MM or 85MM.

Good:
Picture quality - from f1.2 thru f2.8, the lens works superbly. AF is fast & faster compared to 50mm 1.4. Above f2.8, the pictures become a touch soft, but it exceeded my expectation. In low light condition, this lens is virtually unbeatable.
Weight & Feel - Anoth factor that sold me to this lens is its overall feel. Very balanced & well weighted. And, its build quality is good.

Bad:
Back Focus - Yes, it does back focus in very (very) close distance. Within 20 inches, you may experience back focusing more than half of the time. (Others say within 30 inches or so, but I never experienced more than 20 inches far.) I asked myself how many times (in reality), I would try taking pictures within such distance.
Cost - Yes, this is expensive lens. 4 times more than very good 50mm 1.4.

I love to take portraits (especially for my new born baby) , and this was my main reason that I upgraded from 50mm 1.4 to 50mm 1.2. I would recommend this lens if you are into portraits. If you want more than what I am into, you may be disappointed. Did I make a good investment? Yes, I believe I did.

450mm f/1.2 on 5D Mark II
By Caring
You are probably reading these reviews to decide if you will pay $1,500+ to buy this lens or to get its sibling the 50 f/1.4. I owned the 50 f/1.4 for a year, and currently own the 50L 1.2. Ignore the reviews by those who have never even owned 50L 1.2 (or maybe rented it for a weekend) yet feel they can give you a solid opinion about it. I will give you a run-down of my experience with the 50L 1.2 as a portrait photographer:

*********************************
*** Crop vs Full-frame Camera ***
*********************************

This lens is all about narrow DoF. I will talk about the characteristics relating to DoF further in my review. To get the most out of this lens it is recommended that you use a FF camera to give you the most control over DOF. A full-frame camera will give you approx 1.6 times more blur than on an APS-C camera (such as the 7D).

50mm is very versatile on a FF camera, allowing small group photos, individual photos of bust-up / full length / three quarters. But not so much on the 7D, when you will have an equivalent field of vision of 80mm. 80mm is quite tight, and more suited for headshots and bust-up.

*
*
*

*************
*** Bokeh ***
*************

With narrow DoF comes great bokeh. The bokeh produced by the 8-bladed aperture is round and beautiful, currently matched only by the 85L 1.2. The 50 f/1.4 also has an 8-bladed aperture but the bokeh it produces pales in comparison and is often nervous and distracting. With the 50L 1.2, the bokeh has a soft and beautiful rendition - the subject is well isolated and everything out of focus becomes a wash of creaminess.

*
*
*

*****************
*** Sharpness ***
*****************

This is one of the areas where I feel the 50L 1.2 is most misunderstood. I will open my review of sharpness with this: between the apertures of f/1.2 to f/2.0, this lens is the sharpest of the Canon 50mm family. Period. If you don't like taking my word for it, then you can poke around in MTF charts. You must be skilled (yes, skill is needed, this is not a point and shoot lens) at using single focus points, have a steady camera technique, knowing where the blade of DoF falls, and knowing when to not focus and recompose.

The 50 f/1.4 then takes over in sharpness at around f/2.2 to f/2.8.

The 50L 1.2 will never be as sharp as my 85L 1.2 II. But for me as a portrait photographer, sharpness is relative. If the background is pure cream, then the lovely lady I am photographing will look sharp. Also, I don't mind not having the lens a little soft so the photograph does not capture every pore and imperfection on my subject's face. It actually saves me time when retouching later!

As a further note, I found that shooting wide open with the 50 f/1.4 gave results that lacked so much sharpness so as to be unusable.

*
*
*

************************
*** Color & Contrast ***
************************

The color rendition and contrast from the 50L 1.2 is beautiful, and what you would expect from an L lens. The optics and lens coatings are far superior to the 50 1.4 when it comes to color and contrast between f/1.2 and f/2.0.

When shooting wide open with the 50 1.4, I found out of focus areas with sunlight would exhibit color shifts to red and green. The contrast would also be very low - and at times so faded that the photograph could not be fixed (to my satisfaction) in post. With the 50 1.4 closed up to f/2.8, the color shifting was much more controlled and the contrast at an acceptable level.

*************************
*** 50L 1.2 vs 50 1.4 ***
*************************

The $1,500 grapefruit or the $355 non-L?

I would sum it up this way:

1. The non-L is advertised as an f/1.4 lens. BUT, there will be many lighting conditions in which shooting between f/1.4 to f/2.0 will give you less than perfect results (eg. distracting bokeh, terrible color, washed out photos, or complete lack of sharpness). For a professional, it would be a challenge to practically use the non-L at f/1.4-f/2.0 in less than perfect situations. Shooting at f/2.8 and narrower, the non-L is as good as any Canon lens.

2. The grapefruit is advertised as an f/1.2 lens. AND, it is the wonder lens between f/1.2 and f/2.0 for the reasons given above. The color and contrast is L glass quality at all apertures. However, the sharpness is not as good as other Canon lenses from the more standard apertures of f/2.8 and narrower. The sharpness is also affected by the focus shift that occurs because the 50L 1.2 focuses wide open and the aperture is stopped down an instant before the sensor is exposed to take the photograph.

So where does this leave us? Because what I am going to say might insult some people, I am going to caveat that all of this is my own personal opinion - which is totally worthless anyway. Why have you read all the way down to here, hey? Here we go with a deep breath:

3. The $1,500 grapefruit is the lens for you if you love shooting between f/1.2 and f/2.0 for that bokehlicious cream and narrow DoF. It is a perfect versatile complement to the 85L 1.2, 135L 2.0, and the legendary 200L 2.0. I also consider the 35L 1.4 a fantastic prime, but not for portraiture as it has even less lens compression than a 50mm lens.

4. The non-L is advertised as an f/1.4 lens. HOWEVER, in practice, in most conditions it will only give best results when used as an f/2.8 lens. With this limited 'usable aperture', this leads me to question what is the place of the non-L in my lens bag when there is the 24-70L 2.8. The L zoom is as sharp as most primes, and with the high resolution 24-70L 2.8 Mk II just around the corner, the Mk II will blast the 50 1.4 away in sharpness, color, contrast and versatility. For apertures wider than f/2.8, the grapefruit is firmly rooted in its position. Unless you cannot afford L glass (which you obviously can, otherwise you would not be reading this review), then you are sacrificing image quality for something else by putting the 50 1.4 in your lens bag.
