I think it is a bit luck of the draw. The only lens I've bashed properly was a sigma 18-125 which I had mounted on a 350D round my neck . I was walking down a slope very out of breath due to altitude and a chest infection and at some point one of my poles got caught and I tumbled forwards basically landing on top of my camera and the lens smacked straight into a rock, fortunately hood first. No damage to report, focussing wasn't affected and the only damage was a couple of fairly deep scratches on the front of the hood. Very lucky I would think seeing as while the sigma is pretty well built and solid it is far from L lens standard or even sigmas EX standard.

The replacement has arrived and it now has the new style cover, but I'm really tempted to have the old one repaired as well seeing that most of you spent less than half of the value of a new one on it. and it would be convenient to have a spare.

My 50 1.4 rolled of a table about 1m/3 ft above a wooden floor and suffered the typical focusing damage
(infinity was OK, but below 1.5m was not possible)
The lens was purchased second hand so I decided to take the risk - as a local repair with tax would have
been a reasonable sum. Plus I wanted the lens for a private photos at a wedding coming up soon.
I googled and found a very good description (unfortunately the saved link is not on this PC)
[there could have been some improvements especially the couple of things to note when reassembling]
The first disassemble was very slow as I was very cautious. Then a small amount of bending.
Reassembling meant checking everthing double as well.
After the second go I could do unassemble, fix and assemble almost in my sleep in around half an hour...
I fixed it myself after several tries - each time bending the rotating component a little more back into place.
On the final attempt I also filed the component as well - as I noticed a dent or two.
As it was couldn't attend the wedding - the wife falling ill just beforehand.
I have yet to fully evaluate my fix with AFMA etc. but at least it focuses through the complete range now.

Unfortunately the 40mm pancake is still relatively overpriced here in comparison to the US (as is the EOS-M).
And my other option would have bought the 85mm 1.8 for use on a crop sensor...
So I will stick with it for now - not my most used lens - but still comes in handy.
would certainly wish like a quite a few for an update sometime - but dependent on price and any upgrade to full frame - who knows....

This problem is so common that one camera/lens cleaning/repair place I went to, the ladies at the desk knew what the problem was and how much it was to fix without looking in their computers.

I think you'll find many of the smaller, cheaper L lenses are made from plastic

True.. I had my 85 and 70-200 specifically in mind when I said that.  I'm sure both of those would be heavy even if they were made plastic though

My 50 1.4 has proven to be pretty tough.  A few months ago it fell from a table onto a concrete floor, roughly 0.7 meters.  The lens wasn't mounted and landed on the lens cap corner (it also had the plastic cap over the end that mounts to the camera body installed).   The lens cap has a nick in it, but otherwise the lens works fine and looks good.

Costs $200 to fix it in Oz, v buying it new for about $300 on Ebay.

Ive learned to fix the barrel myself, one other thing that can happen is the rear internal lens on the assembly can pop a little, and be at an angle, which makes focus look fuzzy at lower apertures - only needs a push to clip in properly and all good.

All of the problems have been from actual drops, and I guess I must subconsciously hate it, because its had 3 so far.  I got the sigma 50mm as a replacement and its fine, but so tank like I tend to choose the Canon instead.

I have seen countless 50mm 1.4s listed on my local craigslist with broken autofocus.

My guess is that this lens is not very durable... looking forward to a new IS update from Canon.

FWIW my EF 50 f/1.4  was perfect and like new when I made the mistake of selling it as a 12 year old lens to replace it with a Sigma 50 f/1.4. Bad move. I should have kept the Canon!

Mind you I never dropped the EF 50. Drops and falls are weird things. Massive drops can result in miraculously little damage...yet I dropped a 70-200 f/2.8 on a 1D MkIIn body and both lens and body were write-offs. The strap slipped off my shoulder and fell onto relatively soft carpeted floor. Weird...People can fall off a cliff and walk away with cuts and bruises or slip on a banana skin and die.

Yes, hoods are terrific shock absorbers and should be used at all times.

Very true. Depends on the Fall

Can anyone confirm this, or shed some light on it. I'm surprised that canon used the weakest material on what was once one of the most popular lenses.
Its design not materials. Plastic can be very hard, sturdy and cheap.
Let me tell you a story about newer but even cheaper lens, 18-55 that came with rebel kit about 10 yrs ago. I accidentally dropped it from my bag while taking something else out of my camera bag from passenger door (just luck that nothing more expensive fell out of it). It rolled under my car to other side and landed under the wheel of minivan backing out of the parking lot fully loaded with hefty people. Yes a minivan ran right over it. I was dead sure that I have a plastic pulp on the other side. To my surprise, the lens was bit scriffed, the metal mount was bit bent but otherwise looked OK. Glass was clean and even filter was not broken. I just tossed it in camera bag, only to notice again months later. I straightened the mount as best as I could and tested the focus and image quality. I know that f/3.5 does not put high demand on tolerances but still!! It worked as well as it should. $90 lens almost entirely made of plastic survived the weight of minivan !!!
So, I think we have so many broken 50 f/1.4 due to old design of plastic gears packed in light shell.

This won't work with all drops but I have some simple advise that may save some.  When you drop something, stick your foot out to break the fall.  Practice this with all things.  Many times this will break the fall enough to prevent damage.  This will work when you drop something while you are standing (changing lenses) but obviously will not help with something that falls off the camera.  I've save a number of lenses this way.  The downside, reflex.  Once I opened the freeze and a frozen chicken slid out.  I put out my food to break the fall.  Good for the chicken....not so good for my foot :-)

Back when I was dirt poor, I was a huge fan of the 50/1.8.  I went through several of them. But only after completely wearing them out.  Sure, I dropped them a few times, but they're so lightweight that they can handle their own mass and bounce around without much consequence.  Unless, of course a body is attached, or if you run over the camera bag with the car.  Then it's really nice when that $75 lens takes the impact. 

The 1.4 is just too heavy for itself.  Better not to drop it. ;D
So I bought an EOS M and a 6D - I love the black sheep!

The original is sent to canon for repairs, so I'll keep you guys informed of what the cost here (Europe- benelux) is. The store said it could take up to six weeks and they'll keep me informed of the cost before doing the actual repair. if the cost would be too high, I can forfeit the lens and they would not charge examination costs (50 euro)

I have a 35mm F/2.

I dropped it once, and the focus mechanism jammed up.
I read somewhere if you drop it again it may fix it.  I dropped it twice on my carpeted floor from 2 feet.

Focus fixed. 

Thank you Canon.

It's amazing what a lens hood on a 50mm f/1.4 can do for its durability.

The focus ring on my 1.4 also got bent inside a suitcase . Any force whatsoever to shorten the lens will bend it and i strongly suggest permanently leaving a hood on there. I did find this web page and followed it to the letter to fix my lens myself and it worked. Allow yourself a couple of hours of time to do it however.
