hi everyone,
i have been doing headshots lately with a 70/200 2.8 and while I am generally pleased with the results , I haven't shot with the 85 mm canon lens. From what I read, it is a great lens but I would love to know from someone who has USED BOTH!
is it a quantum leap or does one need to really see the differance? Would love to hear some educated opinions..
kind regards,
Simon.
Simon,
Looking for "quantum leaps" in performance of lenses is a dangerous prospect, and can send you down some VERY expensive rabbit holes.
Your 70-200 f2.8 is already one of the finest zooms in its class. I certainly wouldn't expect huge improvements with something else.
The two lenses you are talking about have three basic things in common:
- They both can shoot at 85mm focal range.
- They both can shoot at f2.8
- They both have stellar image quality at f2.8
Now, what's different about them:
- The 70-200 is a zoom with a broad focal range. The 85/1.8 is a prime.
- The 70-200 is very large and very heavy. The 85/1.8 is quite small and compact.
- The 70-200's brightest aperture is f2.8. The 85 will open up to f1.8.
Of all of those similarities, optical quality will likely be the least noticeable. The most noticeable difference involves size and weight.
For me personally, I love the 70-200/2.8 II most when I'm shooting people, mostly single adults or couples, and mostly outdoors. The 85/1.8, however, is a far "friendlier" lens, smaller and lighter to work with as a photographer, and far less "intimidating" for the subject. Although some find it slightly soft at it's full open f1.8, I find that aperture quite pleasing for single person portraiture (though certainly, care should be taken at such thin DOFs).
It can probably be boiled down to the 85/1.8 being a very specific lens, where the 70-200/2.8 is a bit more general. While I can certainly recommend the 85/1.8, there's an awful lot of overlap between it and the zoom, and I could really only recommend it to someone who already knows WHY they want it. If you don't already have a specific thing in mind, it's probably not yet time for you to get one.
