Canon 85mm 1.2L II – Practical usage report.
In my previous article ‘A Quick test of a Canon 85mm 1.2L II‘ I did a quick test/review of this lens. I concluded that this lens has some wonderful properties. Bokeh (background blur) is fab along with great control over depth-of-field. It is very sharp and has great contrast. However it’s focusing is slow, it’s heavy and it’s take a lot of understanding to get the best out of it.
In this article it’s more of a practical report rather than a technical test. It’s real-world stuff.
I borrowed this lens with a specific task in mind. I was photographing a wedding in New York and I wanted to really isolate the subject using the narrow depth of field this lens is capable of. I wanted nice background blur.
Below are a few random extracts from the wedding New York using this lens. There is a mixture of sunlight/overcast/street light. ISO100 to ISO6400. All we’re shot at either f1.2 or f1.8.

What I found
Good stuff:
- Focusing was spot on 99% of the time (see note below in Bad Stuff)
- Very sharp images
- Great contrast
- Excellent bokeh
- Usable and natural looking vignetting (f1.8 or above)
Bad Stuff:
- Focusing was great on the 5D2 but awful on my 5D1 – totally unusable. Will discuss below
- Heavy lens
- Slow to focus
- At 1.2 you need to be very sure of your focus point otherwise it’s a ruined shot
- Chromatic aberration can be quite noticeable
- Prone to lens flare and not in a ‘nice’ way
Notes:
As mentioned above, the focusing using my 5D2 was excellent. Awful on my 5D1. I believe that in order to get the best out of this lens you need a really good focus system. This lens shows some quite extreme image qualities at f1.2. Heavy vignetting being the most significant, even the centre of the image is effected. As auto-focus occurs when the lens in wide open I believe the focus system needs to be very good to cope with the extreme characteristics of the lens. Interestingly I found the lens focuses much better when using ALL the focus points. This isn’t a mode I use much as I prefer centre point focus (like most photographers) and I’m relying on the camera focus system to focus on the correct bit of the subject – but I actually found it surprisingly accurate. Again, as this lens is extreme at f1.2, by using more focus points gives the focus system a more accurate overall view of the subject. This is not a scientific theory, just pure experience. My theory is backed up by using it on the 1DMK2 which gave very accurate (and much faster) focus using either full frame focus or single point.
Aperture. You can use this lens at f1.2 as long as you’re taking into account the extremely shallow depth of focus. I’m talking the difference between focusing on someones eyeball or on the tips of the eyelashes. It’s REALLY narrow! I found f1.8 or f2.0 to be the best compromise in terms of getting all the qualities I want from the image while reducing the risk of mis-focus or the extreme vignetting. For most of this wedding the lens was left at f1.8 and I was very happy with it.
Heavy lens. I found it a little too heavy for extended use. You need a fast shutter speed as there is no image stabilization.
Focal length. I find 85mm on a full-frame camera to be a little too long for me. If I we’re going to get a wide aperture lens then I would probably be more comfortable with 50mm. As soon as I find someone with a 50mm 1.2L I’ll be giving that a try too! (I’ve tried the 50mm 1.4 but I’m not fan).
Last note:
This is a fab fab lens. I really like the extreme depth of field and vignetting. I love the sharpness, contrast and overall image quality. However… it’s a complicated lens. There is no such thing as a perfect lens (I believe that a lot of people expect every lens to be perfect). Every single lens has it’s own unique characteristics. To get the most of out of this lens you have to really understand what it CAN and CAN’T do. You need to understand how it works at different apertures. You need to know it’s limitations. You need to make sure it suits your photographic style. Oh, and of course you must have a good camera to get the most accurate auto-focus!
I hope you found this little article useful. As I said before it’s not scientific. It’s just based on my experience using it. Comment appreciated.
Anyone got a 50mm 1.2L I could borrow?
