Good
Spectacular optics (better than most Canon lenses
of any price), ultra light weight and ultra low price. Perfect as a
normal lens for full-frame digital and film, and a short tele for 1.6x cameras. Excellent for use in low light; I prefer it to the faster 50mm f/1.4 because this f/1.8 lens gives me more accurate autofocus.
Bad
Manual focus requires moving a switch, and the
focus ring turns as the lens autofocuses. With a plastic mount, this
lens won't take much of a beating. In light of its better optical
performance than the $2,200 14mm f/2.8 L II, treat it with the respect it deserves and you'll be fine.

Introduction top

This little lens is Canon's biggest secret.
The Canon 50mm f/1.8 II has fantastically good optics, better than Canon's "L" series wide lenses like the 16-35mm f/2.8 L II.
In fact, this $99 plastic lens gives sharper results than the 50mm f/1.4 USM
I've used, especially in no light. The f/1.4 is soft at f/1.4, and
worse, I rarely get in-focus results with it, while this $99 f/1.8 lens
is sharp at f/1.8, and always delivers perfect in-focus results!
The 50mm f/1.8 II weighs less, costs less, and autofocuses more accurately than the 50mm f/1.4 USM.
Try to hate this plastic-mount made-in-Malaysia
50mm f/1.8 II, but when you look at the images, you'll be convinced. The
mount is plastic, but the glass is all Canon's finest multicoated
glass.
How can this cheap lens be so good? Simple: every
time you ask a lens to do more, like to be faster, to be wider, to be
longer, to offer instant manual-focus override, or especially if you ask
it to zoom, a lens has to get bigger, heavier, more expensive, more
distorted and/or less sharp. Lens design is always a compromise among
these trade-offs.
When you ask for a non-zoom, fixed focal length
normal lens of only moderate speed, it's easy to make the optics
fantastic, and at a very, very low cost if you don't mind plastic.
Did I say "only moderate" speed? Even though it's
only moderate as fixed lenses go, f/1.8 is still over a stop faster than
any Canon EF zoom. This f/1.8 lens lets you shoot at ISO 800, while in
the same light you'd need ISO 4,000 with the 24-105mm f/4 L IS to get the same shutter speed! f/1.8 lets in five times more light than an f/4 lens. This 50/1.8 is also less than one-fitth the weight and less than one-tenth the price of the 24-105mm, and has only half the distortion!
This 50mm f/1.8 II uses the same optics as the
original 50mm f/1.8 EF of 1987. The 1987 lens used a metal mount and
had a focus scale.

Sample image, 1/250 at f/7.1, Canon 5D Mark II. Camera-original JPG (7MB).
Realize that depth-of-feild is limited: the branches at the lower left are out-of-focus.
This was at ISO 200 with highlight (D+) and shadow optimizatton on, and shade A4 WB at +3 saturation.
Flowers. 1/80 at f/7.1,hand-held Canon 5D Mark II, ISO 50, Cloudy WB + A5 trim, Standard picture style with +3 saturation. Camera-original JPG (4.7MB).
In the original image, you can see that they're fake. Note how clearly you can see the depth of field with a lens this sharp.
Tilted Wall. 1/250 at f/7.1, Canon 5D Mark II. Camera-original JPG (7MB).
Again, when looking at the original file, realize
that the camera is tilted-up, to the top and bottom isn't in focus, so
of course it won't be as sharp.
With the Canon 5D Mark II, these would have been even sharper if I had bothered shooting them in CR2 and tweaking later.
Name
Canon calls this the CANON LENS EF 50mm f/1.8 II.
EF means "electronic focus," meaning that there is an autofocus motor in the lens itself.
Optics top
6 elements in 5 groups.
Some surfaces multicoated.
Diaphragm top

5 straight blades.
Stops down to f/22.
Close Focus top
1.5 feet (0.45m) from the image plane.
Maximum Reproduction Ratio top
1:6.7.
Hard Infinity Focus Stop? top
No. You have to let the AF system dial you in.
Focus Scale top
No.
The ring turns from near to far in about 80.ยบ
Depth-of-Field Scale top
No.
Infra-Red Focus Index top
No.
Filter Thread top
52mm.
Plastic.
Does not rotate.
Size top
2.683" (68.16mm) diameter, measured.
1.591" (40.4mm) extension from flange.
Canon specifies 68.2mm diameter by 41mm long.
Weight top
4.320 oz. (122.5g).
Canon specifies 4.6 oz. (130g).
Hood top
None; the front of the lens is sufficiently recessed to cover you most of the time.
Canon's best shot at a hood for this lens is the ES-62 hood, which only fits if you use it with its cockamamie included adapter.
I'd use a rubber hood, like the nice Nikon HR-2, which sells for half the price.
Caps top
52mm front.
Standard EOS cap rear.
