On my 30D, I immediately experienced the focus problems, but I knew what to look

Although not a macro lens, it focuses close enough for head shots and small details (.45m/1.5 ft).There's been discussion on internet forums of back-focusing problems at 1 meter or less between F2 and 4

Not sure how much more I need to know after successfully using my 85/1.2II and 50/1.4 on 90+ weddings in the last 4 years without any focus problems.

This lens receives a ton of negative reviews, mostly dealing with focus problems such as back focus or focus shift

Without re-hashing it, I will mention that I have not had any focusing problems in my use cases

After using it, i have to say it is not sharp and have some focus problems with the mid point on 5d2however, the photos created by this lens with my 5d2 are truly great.

This is where the focus problems come in, from what I have seen

Using any focus point away from the center and I would consistently get a front focus problem

I spent weeks reading all of the reports about the focus problems with this lens

: I broke my 50mm f/1.2 finally.

With the other 50mm primes I've owned, I never got filters for them...seemed overkill on cheaper lenses, but with the amount of moolah you fork over for this f/1.2 bad boy, you'll want to protect that forward element!

If you are a casual photographer taking pics of your kids, the f/1.4 will do fine

This is the daddy-o grande of normal primes: exceedingly well made, sharp at all apertures, contrasty and a riot of smooth 'n creamy bokeh

so I could use my expensive B+W Kaesemann Circular Polarizer with it.

This is the softest L lens I own.

Plus I had my much better photographer friends telling me to go with a nice L zoom lens for the flexibile range.

Sean Reid [...]. rated this as the L lens worth its price tag

They say that amateur photographers embark on an equipment journey...beginning with cheap starter lenses, then to "L" zooms and eventually all roads lead to the elite prime "L" lenses- the 35mm, the 50mm, 85mm, 135mm, etc,

I'm in the process of acquiring a full set of fast prime "L" lenses

It seems to do exactly what it purports to do and then some...it really makes some truly lovely pictures (and yes all that wonderful L color and contrast is there too)

I had a Sigma 50mm 1.4, two tamron sp 35mm and 85mm 1.8, all made for high megapixel wars, but none, no other lens besides the 85mm 1.2 L lens will give u the rendering, the bokeh, the 3d look, the beautiful L lens colors, transition from bokeh to sharpness, the amount of light u can capture with this lens, its superb

Chromatic abberation is rather harsh for an L-lens (even harsher than the 1.8 and 1.4 non-L lenses) and the vignetting on a full-frame sensor is kind of disappointing
