I got this lens not long ago and am enjoying it.  I haven't had many focusing issues.  When I do, it's usually because I am moving, not the lens (wish I had IS on it sometimes).

Sometimes on deep contrasts with white, there is aberation.  Though I've found it that unless its on smaller things, it's not all that bad.  All photos below are straight out of the camera (after raw conversion).

I have this lens also and when its on (your focus is spot on), it's really really good. I haven't had a chance to pair it with my recently purchased 5dmII but I have a photo shoot tonight that will present the perfect opportunity to use that combination extensively.  I'm looking foward to the scrumtious files they will give.

This is probably a good forum to ask this question. Not trying to be snide, I'm seriously curious because I don't know, but what is the advantage of this lens over the f/1.4?

The 1.4 is pretty solidly built, focuses sufficiently fast, and even has a better MTF chart than the 1.2. Yet the 1.2 is four times the price. I have to be missing something because a 1/3-stop advantage and marginally better build and autofocus can't be worth $1200.

The 50mm f/1.4 suffers from a noticeable halation (a softness or 'glow' especially at contrast transitions) from f/1.4 to about f/2.  The 50mm f/1.2L is weather-sealed, and has a more robust AF.  But really, with the L lens, you're paying for the creaminess of the bokeh - check out the bokeh tests on photozone.de for the 50/1.4 vs. the 50/1.2L

Personally, I think the 50mm f/1.2L is a bit overpriced for what it is...but if you want beautiful bokeh, you pay the price...

Isn't it technically a half stop advantage?  I may be wrong.  It is an expensive lens, but I think to have continued sharpness and less problems as the elements get larger, there is some cost trade-off.

It's not just a 1.4 that can do 1.2, but a 1.4 that can do 1.2 better than the design of the 1.4 could.

What is the consensus on the plastic/cheapie EF 50mm f/1.8 II used primarily as an interview, locked down lens for a budget documentary?

As in a film? (opposed to a still picture i mean).
you can't get any more budget than the 50 f/1.8, it's softer and slower than the 1.4, but you can't beat it on price. even filming at 1080p you probably wouldn't notice the softness much.
i'd prefer IS for filming, but if you've got a stable enough mount/tripod, or only doing static scenes, it'd be fine for me...

I've always wondered about the 50 f1.0 L... I've read that it was discontinued due to cost, but doesn't the 85L have more glass than the 50 f1.0?  Is it something about the design?

from what i know about lens design, the only thing prohibiting fast telephoto lenses is size/weight/cost.
But the wider the angle, the harder it is to deisgn something fast with decent IQ, especially at the borders, and especially once you get wider than the diagonal (43mm for FF). Look at the photozone.de reviews of the 35 f/1.4 and 24 f/1.4, their centre sharpness is off the scale at f/2.8-4ish. but their border sharpness is off the other end of the scale at f/1.4.
the 85 1.2 ii is sharper than the 50 1.2, for sure, but it's not the stellar performer itself either. the 50 1.4 looks better on paper, but it's got its own problems as Neuro mentioned (in short, every lens purchase is a decision between what good you need and what bad you can put up with).

I can't find a review of the 50 1.0 on any modern site, too old and i suppose no reviewer can afford it (or noone can afford to lend it to them). the only one is from the site where wikipedia cites here, and that was on film. If it didn't stand up to film, it definitely won't stand up to 20+ MP.

From the canon Camera Museum, it weighs 985g, only 40g less than the 85 1.2 (i or ii). so near enough to the same amount of glass. It's what they do to the glass and what it's made of that makes the cost, and i'd suppose that with all the manufacturing costs put together, plus a decent margin, it was out of reach for anyone but the most dedicated, even then you'd make more money selling to pro portrait-takers who'd rather use an 85 or 100/135mm.

i'm almost wondering, with digital and APS-C these days, if we might see a resurgence in demand for it enough for canon to release a 50mm f/1.0 II version? It makes a bit more sense taking a portrait with a 50mm lens on a crop body than a FF (but then why use a 7D to take a portrait?). and the original f/1.0 was designed in 1989, with computer design i'm sure they could beat the performance if they started fresh now...

Wikipedia states that the f/1.0 lens wasn't particularly sharp at any aperture.  That mixed with cost and higher usable ISO range, the 1.2 became the spiritual successor.

As far as the 1.8 for video, I used it before, and its great, unless you need follow focus.  The focus "ring" is tiny.  It'd do fine with a tripod though.

On the half-stop scale, f/1.2 is 1/2-stop wider than f/1.4, but the 1/3 stop scale also includes f/1.2 at 1/3-stop wider than f/1.4.  See the wikipedia page on f/stops

Mathematically, f/1.2 is closest to a 1/2-stop, since 21/2×0.5 = 1.1892), whereas 22/3×0.5 = 1.2599, which personally I'd round to f/1.3.

While difficult to use at 1.2 in close quarters and slow to focus due to the amount of glass it's turning, this lens is still my favorite because of the wonderful bokeh.  Is it obscenely expensive? Sure.  Worth it? absolutely.
