I used to have 50 f/1.4, then buy the f/1.8 and end up keeping the f/1.8. I found the sharpness f/1.4-2.2 not good enough.

I had two 1.8 versions and both were excellent at 2.8. For me, they were both very soft at 1.8. A lot softer than my f1.4 was at 1.4.

The f1.4 would be a LOT sharper than the 1.8 if they were both at 1.8. Also, it's worth it to get the 1.4 for the USM focus. My 1.8's always hunted a lot and even missed focus sometimes.

Everyone has different experiences with this lens though, but I have to say I loved mine and will purchase another one to keep.

Canon needs a new 50mm 1.4. I know it might bite into their 1.2 profits, but if they made an L-series 50mm 1.4 for around 700, I'd buy it. I'd imagine it to be Sigma's 50mm with weathersealing and canon-af. I can only dream :\

Totally agree. 50 f/1.2L does not perform as high as our expectation in terms of sharpness.:cry:

I switched to a sigma 50 1.4 and never looked back. It's no canoN L when it comes to focusing speed but the sharpness and speed outperformed my canon 50 1.4.

Not sure if my standards are just low, but my 50 1.4 is plenty sharp wide open.

A little bit of CA happening here. Easily fixed in DPP if you shoot in RAW.

I think it also helps when you are using that lens on a cropped body. If full frame then it does get worse at a similar stop compared to cropped. But I reckon it's still the best value when you compare it to the 2k+ f1.2 which is a tiny tiny bit bettter for the extra money and weight. On the other side, the the 1.8 50mm is a joke, don't even get it, stick with your current one, it could be a defect, so try to use another same lens before you sell it.

And if you don't shoot RAW, you can use DxO or Lightroom to get rid of it as well.
If you even care - most of the time, I don't. Unless I'm going to make a print and frame it.

meh, i have the sigma. its not the speed that concerns me (i heard the 1.2 50 and 85 are slow as well), rather its the way sometimes it misses focuses on things further away. It could be me, but I seem to have a bit more mis-focuses with this lens. could be the aperture, could be me. i'd like to blame the lens though :)

I have been having focus issues with my 50 1.4 as well. I just sent it back to canon to see if they could fix it. It is free under warranty to do this. You just have to pay shipping. FedEx ground with insurance was only $11. Worth a shot for sure.

For sharpness i found it better working at f/1.4 on my 5DII than on my crop 50D.

I agree. The lens was totally revived for me when I went full frame. On my XT, focus was off and it wasn't as sharp.

99% of prime lens being soft is due to focus shift

What is focus shift?
Focus shift is a displacement of the sharp plane of focus when the lens is focused wide open, but the image is made with the lens stopped down.

Quite literally, the optimal plane of focus moves, depending on aperture! With every lens I’ve tested to date, the focus moves farther away. For example, if focus at f/1.4 is centered at 1.00 meters, then by f/2.8 it might now be centered at 1.02 meters. That apparently small difference means sparkling-sharp eyes versus not-quite-there eyes—it matters, especially with high-resolution digital cameras.

Focus shift is caused by spherical aberration (see vanwalree.com for an excellent technical discussion). Instead of a sharply-focused point of light a spherically aberrated lens produces a point of light with a “halo”. This is visually confusing when focusing by eye (because of the lowered contrast) making it difficult to find optimal focus. It also is confusing to autofocus systems. In spite of these issues, accurate focus can generally be obtained—but it’s no longer accurate when the lens is stopped down.

Mitigating focus shift
There are multiple approaches to dealing with focus shift. One solution is to avoid f/1.2 and f/1.4 lenses entirely; shoot an f/1.8 or f/2 lens instead! But assuming an f/1.2 or f/1.4 lens exhibits focus shift, here are some options, none of which are entirely satisfactory.

Stop down — unfortunately, the entire zone of focus is shifted, and some lenses require f/5.6 or even f/8 to regain “lost ground”. If your zone of sharpness needs are precise, stopping down isn’t much of a solution. However, given the random variability of focus error, stopping down “kills two birds with one stone”, improving the odds. But didn’t you get that “fast” lens to shoot at wider apertures?

Compensate — deliberately focus slightly in front of the desired point (with most lenses). With practice this is feasible, but it’s a skill that takes time to acquire.

Shoot wide open —what you see is what you get.

Focus at the shooting aperture — focus and shoot at f/1.4, focus and shoot at f/2, focus at f/2.8 to shoot at f/2.8, f/4, etc (by f/2.8 spherical aberration is all but eliminated).

Focusing at the shooting aperture is the only option for optimal results, but not always feasible. Stopped down lenses are not compatible with autofocus, so this means manual focus using the depth of field preview lever (or a lens with a manual diaphragm control eg Zeiss ZF on Canon EOS).

Live View (at the shooting aperture) is the most accurate choice of all, but requires a static subject and a tripod. Beware of Live View that automatically stops down the lens under bright conditions, and then exposing at a wider aperture than the focusing aperture. Canon EOS does this with Live View mode.

Autofocus compensation — some cameras now offer a lens-specific focus compensation adjustment. If you know you’re going to shoot (for example), the Canon EF 50mm f/1.2L at f/2, you can “dial in” a correction factor to front-focus slightly, correcting the focus for f/2. This feature is available on the Canon 5D Mark II. Nikon also offers the feature on the D3 and D700. Of course, correcting for f/2 will throw off other apertures.

Conclusions
For the full report on focus shift, subscribe to DAP (see Table of Contents).

Photographers utilizing the f/2 - f/4 aperture range with f/1.2 and f/1.4 lenses at close range (eg portraits) must take into account the focus shift characteristics of the lens. The shift is enough to throw eyes out of focus, or at least to render them with less than crisp detail.

It would be no surprise to find that many of the complaints read online about lenses being “soft” are due not just to focus error, but focus shift, particularly when assessed in the f/2 - f/4 range.

Some cameras today offer a fine-tuning autofocus adjustment on a lens-specific basis. It would be a modest step for Canon and Nikon to allow this functionality for the aperture range of the lens, allowing the user to dial in focus compensation for f/2, f2.8, f/4, etc; the camera could interpolate intermediate partial apertures.

I have one and love it. This is my second copy, my first one was quite soft wide open.
Another issue I had was when I was very close to my subject shooting f/1.4.
Because the DOF was so narrow it was hard to get a nice focused shot.
Between half press and actuating the shutter any movement shift would put me out of focus.
It's now my favorite lens that rarely leaves my camera.
It just took a lot of practice to make this lens work for me.

I have never tried it before but I was able to remove the CA from the jpeg using Photoshop Elements and this tutorial:

Thanks for the inspiration to learn a new trick. :D
