But, honestly, it's built about as solid as a toy prize in a box of Cracker Jack. After a few months of use - use, not abuse - the lens literally came apart, the front barrel separated from the mount. The bad news was that the lens was completely shot - it was in pieces, after all - the good news was that it had been cheap, so my pocketbook was able to stand the cost of replacement.

I replaced the lens with it's older brother, a used version of the Mark I - much more solid, and which gives equal optical quality even used. It's a shame that the body and housing on new version of this lens is so shamefully cheap, because the glass is very nice. But I can't recommend it, unless you either a) don't do that much shooting, or b) don't mind replacing the lens on a fairly regular basis.

My suggestion is to either cough up the money for Canon's 50mm f/1.4 - gains you a half a stop and is built to pro-quality standards - or pick up the older version of the f/1.8 on the used market. Either option will likely end up being cheaper in the long run.


Perfect Portraits: Canon 50mm f/1.4 vs. f/1.8 Lens Comparison   August 19, 2005

The 50mm/f1.4 and 50mm/f1.8 are the BEST PORTRAIT LENSES that Canon offers. I own a Canon Rebel 2000 and Digital Rebel XT and have used both these lenses for several months. Pictures have been outstanding and my professional customers frequently cite the sharpness, light balance, depth of field, color reproduction, and "bokeh" (intentional blurring of background in portraits) from these lenses. Some people question the usefulness of a 50mm lens on digital SLRs with a 1.6x crop factor (i.e., 50mm lens = 80mm on a dSLR like the Digital Rebel XT)... I can vouch that the range is beautiful and relevant, focusing more closely on key subjects in portraits.

WHAT DO THESE LENSES HAVE IN COMMON? They are both fast (the f1.4 is blazing fast - dSLR can hardly keep up!), details are incredibly sharp (you can see individual hair strands), virtually no chromatic (color) aberration, no dithering or shadows in the corners, focusing is rapid and quiet (thanks to Canon's patented Ultrasonic USM technology) and photo quality parallels even my professional Canon "L" lenses. These fixed aperture lenses also provide superior pictures than telephoto lenses at 50mm because of better glass and aspherical elements.

HOW ARE THESE LENSES DIFFERENT? Having tested both lenses across 1500+ pictures, there are 5 key factors that make the f1.4 superior (justifying the $300+ price tag).

1) FASTER ESPECIALLY IN LOW LIGHT: Extra f-stop makes the f/1.4 better for indoor photos or low light. Great companion to the 480EX flash. I was able to take nearly 40 pics/min with flash and the fastest Sandisk 1GB Ultra II CF card

2) NO CHROMATIC ABERRATION, whereas the f/1.8 has slight yellowing of photos under certain lighting conditions or where edge definition is low

3) FULL AUTO/MANUAL FOCUSING RANGE: f/1.8 requires flipping between auto and manual using a switch, while f/1.4 can be manually "hot" focused/tweaked after auto focusing

4) SUPERIOR BUILD QUALITY: The f/1.8 is plastic and feels cheap, like it might fall apart anytime. The f/1.4 is metal, weighty, and is for the proud lens owner

5) CLEANER "BOKEH" - f/1.4 produces beautiful blurring of background in portraits ("bokeh") while the f/1.8 leaves less clean edges. Canon reviews suggest this is due to the f/1.4 having 8 lens elements vs. 5 elements for the f/1.8

WHICH LENS SHOULD YOU BUY? This is a question of utility vs. value. The f/1.4 costs over $300 while the f/1.8 can be acquired for under $75. The f/1.4 will last forever while the f/1.8 will probably break under normal use in a year. Does this justify the 4x price tag? If you are a budding photographer looking for a "play lens" then the f/1.8 will more than over-deliver. If you are a photo enthusiast who looks for "the perfect shot," you will want the f/1.4 because it surpasses every expectation (and so you're not left wondering, "what if"). If you are a photo professional, you already have the f/1.4 lens among your bag and are not reading this review. :-)


Best lens for the money, every EOS owner should have one.   July 30, 2004

5 star for value and picture quality.

With the money of 1.4 version, I can have 4 of this, you only lost half stop of aperture. It is cheapest Canon lens yet produce probably the best result. 80mm focal length on Digital Rebel and 10D means it is the best solution for portrait lens.

Yeah, plastic lens is not as good as metal one. But I really doubt if it will break any time.

for 75 bucks, every EOS owner should have one.

I've had the 50mm f1.8 for about three months now, so I wanted to put in my two cents worth after a little field use. What originally attracted me to this lens was, obviously, the price. It is very, very inexpensive. This is likely due to the fact that the housing is, unlike its predecessor the Mark I, entirely plastic. That initially put me off, but after seeing some images posted that had been taken with this lens (and after seeing the prices of the f1.4 and the used mark I)I decided that I really had nothing to lose. There are, as with most lenses good and bad elements to this lens. Lets start with the bad.

Keep in mind that if you are shooting a canon DSLR (as I am) this 50mm lens actually behaves as an 80mm lens, so it isn't that terribly wide. The fact that it is functionally 80mm can make framing shots a bit difficult. This is definitely a secondary lens and really isn't that appropriate for a "walking around lens." At least it isn't for me, as I tend to prefer shooting wider angles.

If you have some sort of mishap with your camera, like dropping it, you can likely kiss this lens goodbye. I have fortunately never had to test this, but I imagine that it wouldn't stand up to any sort of impact very well. The flimsiness of the build is very obvious when compared to some of the older canon lenses. MY 35-135mm USM is about 10 years old, and has a metal chassis. These lenses can often stand drops and still operate. This is not so for the 50mm mark II.

Since everything but the glass is bare bones, the autofocus isn't terribly fast. If all you have ever worked with is USM lenses, you will have to be ready to take a little more time focusing. If you have experience with the 18-55mm kit lens, you will find that it is about the same.

All that being said, you are probably wondering why I rated this lens at four stars instead of, say, three. That's because there are a lot of nice features to this lens that far outweigh the bad.

If you have never used a prime lens before (meaning, a "fixed" lens that doesn't zoom) then you are in for a pleasant surprise. It is far more expensive to build a quality zoom than a quality prime, thus decent zooms tend to cost a mint. Also, zooms are only at their best in the middle of their range. The 50mm doesn't move, and so has been optimally designed for its focal length. Shots are sharp at all aperture ranges; shots at medium apertures (f8-f11) will blow your mind. Really. Search the web for some images made with this lens in those ranges and you will buy it. Resistance is futile. Canon may have skimped on the body, but they didn't cut corners on the glass. It is excellent.

The wide aperture (f1.8) is really outstanding as well. I had never really worked with a lens this fast before because, frankly, I hadn't been able to afford to. You dispense with your flash and handhold at levels that you would not have thought possible. And once you get away from flash use during night/lowlight photography, you will see some truly amazing colors that flash typically obliterates.

The fact that it is fixed, and not too wide, forced me to be a little more creative than I normally would when framing shots. When I went to Burma this year, I left my principal lens at my hotel, and didn't realize it until I was far away, so I was forced to use the 50mm as my principal lens. Some of my favorite shots of my whole trip actually come from that day, as I was forced to come to terms with the focal length limitations of the lens.

And finally, there is the price. A lens with glass this good that costs less than a filter setup, or a dozen 8x10 prints? How can you say no? Unless you have the bucks to spend on the f1.4 or the Mark I, this lens belongs in every EOS shooters bag.


Sharp, fast, inexpensive   April 10, 2005

Once upon a time the 50 mm lens was THE standard camera lens and was THE optical benchmark by which manufacturers were judged and compared. Although the basic lens focus has now shifted (at least at the low to mid amateur level) to zooms - you can still benefit from years of research and development that went into designing the 50 mm lens and this here lens may be the best lens, dollar for dollar, that you can ever buy. The question is can you afford not to own this lens?

Years of development have brought us a lens that has a fast aperture of 1.8 - far faster than any consumer zoom lens - and that is sharp as a filed tack. Be forewarned about the sharpness . . . if you are taking pictures of people, this lens is unyielding in its sharpness and may well surprise you and your subjects whose every blemish is captured. The lens has a fabulously shallow depth of field if you want to use the 1.8 aperture to blow out a background. This lens is also ridiculously inexpensive. It is not USM - so it is a little loud. It does not have a moving focus scale. For the money though - this is heaven.

As to the build quality - yes, it is plastic. No, it's not built like the Rock of Gibraltar. If you are going to give this lens extensive use as your everyday lens and you shoot a lot, it may not hold up all that well as one reviewer suggests. However, I've now had this lens and used it fairly regularly (although not as the primary lens) for about 8 years and it is still in great condition. In my mind, spend the $$ on this first before you go and drop $330 on the 50mm 1.4 USM lens and I think you'll find it gets the job done nicely and that the extra $250 on the 1.4 may not be worth the difference in build (major difference), speed (minor difference) and image quality (minor difference).
