hello to all!
I have the 50 1.8 and I am considering an upgrade to the 1.4 version.
Can you give me some examples in which one is better than the other? (IQ, not USM, built, etc)

Version 1.4 is sharper? Bokeh?

Thanks a lot!
 
The bokeh is much better on the 1.4, though the 1.8 is supposed to be a bit sharper wide open.

Personally, I never cared for the plastic mount, which is why I went straight for the 1.4. But I recently sold my Canon 1.4 for the Sigma f/1.4. I find the Sigma to be a bit sharper, with better contrast. But it's hit or miss whether you get a good copy. My second copy of the Sigma was much better than the first.

I also find the ergonomics of the 1.4 to be almost worth the cost difference alone. You can actually grip the focus ring. It hunts less and is much quicker AF in my experience. I dunno, maybe I had a junk nifty fifty, because I hated the thing and it has quite the cult following.

hummm...
I like my 1.8, I don't care about plastic mount but I'd like to learn the difference between 1.4 and 1.8.
Can you post any of your pictures?

Here you are one taken at the golf course in my city (Golf Club Trieste): amazing 50 (1.8) @2.8!

I don't have them on this computer, but I could dig some up later. However, two points:

1) there's a ton of comparisons of these two lenses online, far more formal than anything I can provide
2) I don't think there's a ton of difference in IQ, other than I think they're both soft wide open, but the 1.4 is far better at 1.8 than the 1.8 is wide open. This, coupled with better ergo, build, bokeh, and faster AF made it worth the price difference IMHO. YMMV.

Yep. I have read some but I found them not satisfying.
Here in a forum I have the possibility to orient my questions as I want...!

Infact I have never read about "bad and good" copy of Sigma 1.4 model ;D

The Sigma 50mm f/1.4 is optimized for APS-C , while the Canon 50mm f/1.4 performs better on FF.
Reasons to upgrade are
F/1.4
Better build and reliability.

Downside to Sigma - commonly have AF issues (for those that check) and need to go to Sigma for adjustment. None of them have AF that is outstanding.

The Zeiss 50mm F/1.4 is my favorite because it has hyperfocal focus markings making it an ideal street lens shot at F/8.

Manual focus works with focus assist on a 5D MK3 pretty accurately, especially using back button focus.
Hold in button with thumb and adjust focus until you get a beep and red indicator.
Use spot metering for more accuracy.

Has that lovely Zeiss look and at F/1.4 the bokeh is nice too.

A lot of replies above highlight the exact reasons I don't currently own a 50mm.
Canon 50mm f/1.8 - poor AF (hunts and inaccurate, I had 2), poor bokeh
Canon 50mm f/1.4 - not sharp enough wide open, micro USM AF not so reliable
Canon 50mm f/1.2L - too expensive / too big and it has that focus shift issue
Sigma 50mm f/1.4 - too many reports of AF issues (also with different camera bodies)
other 50mm's (eg Ziess). I need AF!!

The Sigma 50mm would probably actually be my 'choice' if I was forced to choose. I'd go to a local bricks and mortar shop where I could try before I buy (the actual lens) - and I would use a shop that has a good return policy.

But in reality, I'm waiting for a new Canon 50mm USM, hopefully at f/1.4, but I will consider even if it's a f/2, and even if it has STM focus (rather than true USM).

IS would be an additional bonus (not quite an essential for me, but definitely a plus if IQ is still great wide open).

The new Canon 35mm f/2 IS USM is 'promising' - in that, I hope Canon keep the same format / standard in developing / producing a similar 50mm!

Cheers 8)

If you can get a really good copy of the Sigma 50mm f1.4, it is supposed to be better than the Canon 50mm f1.4. So if you know someone at the camera shop and they let you test a whole mess of new ones, do that. The canon 50mm f/1.4 is better than the f/1.2L across the board... which is strange since it is a fourth of the price.

I haven't looked at the Zeiss yet.
IF you drop it while the lens is focused on something close that that lip sticks out, it moves the gears off its track and it is screwy thereafter. So I never take off the hard plastic hood.

I'm pretty much in the same boat, I've had numerous 50mm lenses, three 50mm f/1.4's and at least 6 f/1.8's. I had one older 50mm f/1.8 MK I that was really good, the rest of them were fine, but not outstanding.
Last week, I sold all three of my remaining ones, two 1.4's and a 1.8 MK I. I decided to order a 24-70MK II after holding out for quite a while.

50mm just does not seem to be a focal length that works for me.

I have a Sigma 50mm f/1.4...on a FF body. Is it perfect...no...but from a price/ performance standpoint it is the best choice for an AF standard lens for a FF body for my needs. The Canon f/1.4 has its own focus issues, too, which no one has mentioned so far.
I just put the lens on the camera and shoot...I don't sit around and fuss with it. It makes great images! And you can pick one up for $450 right now.
Pretty sad that the choices are kind of shabby for Canon FF users for a standard prime. The Canon situation in this Dept is embarrassing as far as I am concerned.
Perhaps Sigma will make a 50 f/1.4 lens for its new Art Line Lenses. I would like to see that....but their current 50mm is just fine with me....

Same as saying - this car is not reliable, it breaks when you drive it into a wall. - :)
Isn't it photographer's fault? I've never dropped a lens, or a baby, or a cup of hot coffee/tea. Phone?- sure! :D many times (no damage though). You just have to be extra careful with some things more than others. I see how careless people are with their gear while showing off on youtube. They drop it. They rub the table with their camera LCD while attaching a lens. They throw it around with caps taken off letting dust and stuff to get inside. They don't keep it clean, it's always covered with dust. They focus manually a non-FTM lens while it is in AF mode. ... all kinds of careless behavior :o ... and then they complain about something. It's kind of funny to watch :D.

What does that have to do with reliable AF?

Canon will be updating the 50 and maybe the 85 like they did with the 24, 28, and 35. Unknown what the final aperture will be on the new lenses but the build quality will most definitely improve. Now, while waiting for a current 50mm to be built for EF, why not consider getting a 40 f/2.8 STM? Image quality is excellent and the lens is very inexpensive.
