I just got a 50 f/1.4 and so far am disappointed by the results, however i have reason to believe it's partly my cameras fault. I've never had any focusing/sharpness issues before with my current lenses, my 70-200 f/4L is razor sharp. My 50 f/1.4 has been soft even at slower apertures and especially around 1.4-2.0. However I let my friend try the lens on his Rebel xti and the pictures were very sharp.

So here we have a case of a sharp camera with a sharp lens, combining to produce soft images??

Often it's not the camera nor the lens alone but the combination of the two..

Post a few examples..

Its just the 50 1.4 man, sorry to say. The 50 1.4 is a soft lens at those aperatures. I went through 2 copys to realize its just the lens, and it wasn't for me.

It doesn't start to get sharp until 2.5 - 2.8

what kind of camera do you have? if you have a (18MP +) t2i, 5dm2, etc etc, 100% on your pictures WILL look softer than the XTIs because you are asking much more of the lens, resolution wise.
PLease do post some pics so we can see what you are talking about.

His post title indicates he has a 40D.

I am very interested in this topic since I own the EF 50 f1.4 lens and have used it with both the 40d and now with the 60d.

I have also found the lens to be very hard to focus. Pictures are not as sharp as I would expect. I however assume it is my lack of experience. Both using a flash, as well as w/o, I simply have not been getting good shots.

Yeah, the 1.4 doesn't get really sharp until f/2.8-4 or so... it's just the lens. Just have to deal with it :D I had one and wasn't impressed enough to hold onto it.

I seriously doubt he was pixel peeping. Looking at 100% is often not a good indication of anything. I went through 2 copies. Both a bit too soft from 1.4-2.8 (for my liking). MTF charts confirm it.

.

maybe it depends on what is really sharp and just "sharp". The OP needs to post pics

@1.8 :D Otherwise, it's nearly as sharp as the 1.4 at matching apertures. At less than 1/3 cost, it's little wonder that people pass on the 1.4.

Myself I think it just takes a bit of care and practice! I use my 50mm F/1.4 on a Canon 7D with pretty good results, even wide open.

Maybe some microadjustment on the 5d2 is in order?
