Some Information About the EF 85mm f/1.4L IS [CR3]
« on: August 12, 2017, 06:09:24 PM »
We’ve received a bit more information about the upcoming Canon EF 85mm f/1.4L IS.

Canon EF 85mm f/1.4L IS Known Specifications:

  • 4 stop image stabilization (previously mentioned)
  • Flourine coating
  • 1 moulded aspherical element
  • 9 aperture blades

We currently do not know the weight, dimensions, announcement date or how much this hotly anticipated lens is going to be.

We’re also going to put a [CR3] onto the tilt-shift lenses we’ve been reporting about.

1 moulded aspherical element

Interesting, and may indicate the lens will come in at a lower price than expected (although knowing Canon, maybe not  ;) ).  Canon uses four types of aspherical elements, ranging from low to high cost/quality as follows:

  • moulded plastic
  • replica elements (resin layered on glass)
  • moulded glass
  • ground and polished glass

For comparison, the EF-S 18-55 kit lens has a moulded plastic aspherical element, the EF-S 17-55 has one moulded glass aspherical and two replica aspherical elements, and the 85/1.2L II has a ground/polished glass aspherical element.
EOS 1D X, EOS M2, lots of lenses

I think the price will be around $1,000. I certainly don't think it's going to be north of $1,500

The 35 1.4 II and 24-70 2.8 II also have glass-molded aspherical lenses. Those aren't cheap lenses.

no mention of blue spectrum refractive optics, huh?

I'm wondering the same thing. If its priced between the 1.2 and 1.8, it may not have it at the expense of aberrations. Fingers crossed.

An fast prime like this would benefit greatly from BR optics technology.

I'm going to be really disappointed if Canon doesn't incorporate it into this lens.

The Otus 85 doesn't have BR and it's a decent lens nevertheless ;)

Really? Are you optics designer?

I am only physicist and no specialist in optics: In my opinion BR is helpful for HIGH APERTURE WIDE ANGLE lenses but not effective and/or efficient for tele lenses.

About weight & size: I am interested in compact lenses with moderate weight. So I would welcome a size in thre region of the existing 1.8 85 plus 2cm in length + 1cm in diameter. For ME some small penalty in IQ would be o.k.
If the development goes into the direction larger and heavier I might add a SpotMini robot + some spare batteries for it to help me lugging some lenses for extended walks :) (SpotMini: https://www.bostondynamics.com/spot-mini )

About the price: 2x the 1.8 85 + 500 ($, EUR) for the IS group of a large aperture lens + 100EUR for "it's a new/unique spec combination" ... resulting in 1200 ... 1300 $/EUR ... just a guess.
Most used tools: EOS 5D i  + 4.0 70-200 IS + 2.8 100 Macro & EOS M i + 2.0 22

In my opinion BR is helpful for HIGH APERTURE WIDE ANGLE lenses but not effective and/or efficient for tele lenses.
What do you mean by "high" aperture. Did you mean "large", as in f/1.4, or did you mean high aperture as in high f-number, like f/16? I don't know much about BR (other than it is what they used in the 35L II).

About the price: 2x the 1.8 85 + 500 ($, EUR) for the IS group of a large aperture lens + 100EUR for "it's a new/unique spec combination" ... resulting in 1200 ... 1300 $/EUR ... just a guess.

I think it will be higher. My guess is 3x the 85/1.8 + 500, resulting in about $1600-$1700, but even then it would be priced similar to the competition pricing for 85 f/1.4 with no IS.

Nikon 85/1.4 : $1600
Sony 85/1.4 GM : $1800
Sigma 85/1.4A : $1200

I don't think it will be priced like the Sigma. Canon "can" sell it for much higher if the quality is superb. The 35L II is about twice the price of Sigma 35 Art (1700 vs 900)

I am interested to know why do you guys think it won't be priced over $1500?
