IMO the real advantage of the 1.4 v 1.8 is how good it is at f2.

Of course if you really need that shallow DOF it comes in handy.

But unlike the comparison between the 50mm lenses, where the f1.4 is much better at f2 than the f1.8, the 85mm f1.8 is an excellent lens even wide open.

A great place for checking out lens performance is:

Very true - The 50 f/1.8 is not so sharp wide open until close down a stop or two where it'll shine @ f/2.8

The 50 f/1.4 and 85 f/1.8 are all excellent starting from f/1.8 if you need the perfomance this fast! Photozone also reported similar MTF results in their findings:

depemds on the use and what body you have. with 1.6 crop factor the 50mm is not bad for some portrait work.

I have the 1.4 myself and find it useful as a walk about general purpose lens...but I have 1.6 crop factor. otherwise it would be too short.

Portrait doesn't necessarily mean medium telephoto. I mean heck half of the Magnum photographers only use(d) 35mm lenses.

Steve McCurry's favourite lens is a 50mm.

I prefer around 40-45 as a portrait length so I can work with either a 35 or a 50. I mostly use a 50 at the moment. (No crop factor).

It all depends on the kind of photos you like taking. I find the 85-100mm head and shoulders portrait to be generally very boring.

The 85mm is a nice lens - and there's no reason not to use it for portraits, but I do worry that everyone calls it a portrait lens and some people get the impression that if you want to shoot portraits that's the right focal length. It's not. It's just a fairly popular one.

it depends on the type of portrait you want. Head shots = 85mm, more torso to 2/3 length = 50mm.

Exactly, there is no answer as it will depend on you. I use my 85mm more as it suites my style but that does not make it the best for you.

I am just buying both right now ( 50mm and 85mm ) then I figure out which one I like better. I should have them in 4 days ground.
