Hi,
Has anyone used or got both lenses? If so what is different apart from the focal distance, as it will be my next lens in a few days. Any help would be great. Thanks.
 
Yes, both, and as you guessed the principal difference is focal length (shocker!)

No build or supposed AF issues on either in my case. Both are smack on.
 
I prefered the 85mm focal length over the 50 when I had them (sigma 50 canon 85) but that was me.
 
I used both. Found that I liked the 85mm on the 5DII and the 50mm on the 7D,
Found the 85mm too long on a crop body even though it was sharper than the 50mm (not much though).
 
Thanks I think the 85 would be better on my D700? Hmm thanks for the replies.
 
I haven't yet used either.. but I want the 85mm, thinking it would be a perfect counterpart to the 30mm on a crop sensor.

Take a look at the shots you've already taken and would like to take again in the future, are they generally closer to 50mm or 85mm? It's not about whether it's better for the camera (it doesn't care), it's about whether it's right for you with that camera. And we're not you.

I know for a fact that it will be the 85 as I have the nikon 24-70 and it's always at the long end for portraits, only at 24 for landscapes.
 
I have both and they're both good lenses IMVHO.

I think that the 85 is very probably a little sharper wide open and of course it's bigger and heavier then the 50mm. If you're choosing between the two I suppose it comes down to how important the three big factors are...

They give a different FoV.
The 85mm is bigger.
The 85mm is sharper wide open, IMVHO, although the 50mm is no slouch in this respect.
 
How much would you pay for a 2nd hand sigma 85? almost a year old and UK model.
 
In my personal experience:

Sigma 85: better wide open - sharper, much better corner sharpness, better colour and contrast.

Sigma 50: better closer focussing distance, soft corners - but can be used for creative effect, i like the dreaminess quality to the lens.

Both lenses have buttery smooth bokeh, almost identical build and the differences between the two in centre sharpness terms is pretty negligible by 2 - 2.8

In my own experience, AF is more accurate on the 85, especially at closer focussing distances wide open, although the AF on the 50 might be a smidgen faster, there isn't much in it though.

Personally, now I've done the change i actually think the 35 1.4, 85mm 1.4 and 135 f/2 lenses are a better combo than the 50 and 85.

I think the Sigma 50 is a great lens, the 85 is better (imo) but the difference between the two quite small optically and in focal length terms. there might not be enough difference to justify having the two so opt for whichever one works for you.

This comparison from the digital picture is representative of my own experience:
