Roger over at Lensrentals.com has completed his OLAF testing of the brand new Canon EF 85mm f/1.4L IS. There are lots of charts and all of that to look at.
From Lensrentals.com:
This is a lens where the designer has focused on being very good in as many situations as possible rather than obtaining the highest possible MTF. It’s apparently designed for the person who uses 85mm in a lot of different situations; especially in low light situations.
It’s very sharp, the field is designed to get good focus no matter where you focus, and all reports indicate that the focusing is quick and accurate. If you take a ton of shots, your keeper rate is going to be exceptionally high. And if you shoot in poor lighting with an 85mm it will be amazing compared to almost anything else available in Canon mount. Real the full test at Lensrentals.com
I also must say that I didn't realize that current EF 85mm f/1.2L II uses an optical design from the early 1970s, that's a pretty incredible run.
The Canon 85mm f/1.2 II lens, the king of creamy bokeh, is basically a 40-year old optical design first released in 1976 (in FD mount) and released as an EF mount lens after some slight optical modification in 1989. The “II” version, released in 2006, was an electrical/mechanical change only, the optics remained the same. That’s an amazing run for a photography lens. It was designed in the early 1970’s and is still used frequently today.
Consider this day a success.
