Canon 85mm f1.2 Mk II vs Mk I

[jogle]

Hi All, I'm using a 5D and I've been offered a Canon 85mm f1.2 Mk I for a pretty good price, I'm just wondering how big of a difference there is between the 2 different versions. I've searched the forums and the web and the best info I found was this

http://www.the-digital-picture.com/Reviews/Canon-EF-85mm-f-1.2-L-II-USM-Lens-Review.aspx

Is a 9yr old MkI worth a third of the cost of a new Mk II? it seems to be in great condition and is still accurately focusing.

Any help in making up my mind would be great :)

Yes, the original version has a reputation for being slow to focus. As long as you understand that limitation, and as long as that slowness doesn't impact on your plans for using the lens, you should find the optics to be pretty great.

If you have an opportunity to test the lens on your camera before you commit to the purchase, maybe that would help you decide.

I own an original 85mm f1.2 L and it is not as fast as a 50 f1.4 USM to focus.

In a studio where you are not moving around fore and aft this is not a significant issue. For a journalist on the street it might be.

The optics and bokeh of the older version are still stellar.

The only reason to purchase the 85f1.2 L is if you plan to shoot it wide open. ( That, and bragging rights - it is a humongous lens )

The 85 f1.8 is much cheaper, smaller, and faster to focus, and very sharp at apertures smaller than f2.8.

Thanks for the push, I am going to try it out tomorrow and take it if I like it.

I'm not planning on using it for sport, it's not something I shoot a lot of, and I have a 70-200 f2.8L IS for those moments anyway.

Just need the 35 f1.4 to complete my bag of primes.

Castleman compares the 85mm 1.2 Mk I vs the Mk here:

He says:

With the introduction of the EF 85mm f/1.2L Mark II, Canon has made major improvements in their legendary f/1.2L lens including:
1.8x faster autofocus: Autofocus in the EF 85mm f/1.2L Mark II is now fast enough to use in sports and other fast moving action photography;
New lens coatings: Flare is markedly reduced which results in better image contrast in unusual lighting situations;
Round aperture diaphragm to f/2.5: Results in smoothed out of focus aperture diaphragm patterns at apertures from f/1.4 to f/2.5
Electronics changes to support E-TTL II flash function
