Samples of Canon 85mm f1.4 IS posted by DPreview

[slclick]

Those are not exactly the type of images you would want to use to highlight a new, expensive, highly anticipated and (generally speaking) specific use lens.

Peripheral AF points test results for Sigma 85 F1.4 Art on Canon 5D IV are in. 54 images were taken sequentialy, in difficult lighting conditions, AV mode, ISO 100, F1.4 and shutter speed ranging from 1/25s to 1/100s, mirror lockup, each shot defocused away to infinity, on stable tripod, remote shutter release.
Top left corner cross type AF point was used, Phase Detection Auto Focus. (no live view mode was used).
RAW files were cropped to target size and converted to JPEGs with NO processing, no lens correction, colour, sharpness, noise reduction, etc: absolutely no adjustments made, no down-sampling, etc etc.

result is more than satisfactory.. I am not sure what happened to Dustin Abbott Sigma 85 Art peripheral AF points consistency results on 5D IV body. I would hazard a guess that something was not quite consistent in his test methodology. The sample size of my data is large enough to be conclusive.

AF consistency (QoF) is : 96.5%


this is an _absolutely_ rock solid result.

I will follow up with detailed test report in a few minutes.

p.s. I will be conducting exhaustive Sigma 85 Art AF tests on 5D IV with peripheral AF focus points over the weekend.

Don't forget to post your findings!

Very impressive! Thank you for sharing your experience!

no worries,

it is actually: 95.6%. my mistake.
I have attached test report to my previous post. Honestly, I did not expect the results to be that solid and in a pretty bad lighting conditions. peripheral AF points were a bit of a worry to me but now I am confident in the lens.

Please note: Lens has been identified as Canon EF24 f/1.4L II at 85mm That's by design.

all test images are available on request.

Oh wow, this is a really great result. Yesterday I also spent the evening with this lens on the 1dx2, and I think the lens is solid. Two notes (fine-print Sony style ): the Servo mode contributes to some misfocusing, even shooting a slow moving subject, and it doesn't work well with non cross type focusing points. Basically nothing new. The Servo mode still wroks better compared to the 85/1.2II. Another thing - the lens focuses better/more reliable on the 1dx2 compared to the 5DsR. Probably no-news again. Could be also due to some improvements in the focusing module of the new generation of Canons.

 

[SecureGSM]

Jopa, 1dx2 apparently built with a dedicated AF processor and a battery that is capable of driving heavy glass fast.

no surprise that non cross type AF points are under performing. that seems to be a common issue. I was advised to switch them off in menu. The lens is a keeper for now.

p.s. AI Servo mode: it really depends on the settings and case you choose. at any rate, I would not shoot a moving subject with 85mm lens at F1.4. stop down to F2.8 at least and grab a nice and fast focusing 70-200 F2.8 lens while you are at it so you can adjust your framing as you go.

 

[Jopa]

The lens is a keeper for now.

Indeed my friend!

Planning to take it for a photo shoot of my girls this weekend as soon as the grass dries out (I hope it will) The 85mm delivers exceptional portrait look with some surroundings which are pretty much missing on the longer telephotos (like 200 or 300). It's a great time of year - full of colors, time to take some nice pics!!!

 

[Jopa]

Oh just noticed your edit. Yes, the 70-200 II is a gem in the Canon lens lineup. Used it recently on our family trip to Smoky Mountains. But the 85A @ f/2.8 optically is a killer. I just use my feet to zoom in and out

 

[Ozarker]

Again, no BR (Blue Goo). I have to now wonder why BR has just about disappeared. Then again, this lens might have been designed before BR was developed.

Not a wide enough lens to need it.

A 600mm DO with BR is rumored to be coming. I also thought that maybe the longer focal lengths wouldn't see a benefit. Since reading about the 600mm DO, I have no idea why. Maybe it is only used with lenses that need help with CA?

It could be just a rumor. It will be definitely DO (as Canon demoed it), but not necessary BR. I'm also wondering how expensive it's going to be...

From uncle Roger hot of the press:

Testing Lenses: Stopped-Down MTF Curves

... Today, I’m going to present data from Canon, Sigma, Rokinon, and Zeiss Cinema primes. Why? Because those are the same as the photo primes optically, so what happens with the Cine lenses is representative of what will happen with photo lenses. We get a two-for-one special...

... 85mm

Yes, everything is sharper at T4. But the 85mm graphs, I think, may surprise some of you. They did me, at least a bit.

The Canon and Xeen are basically soft-focus lenses wide open, and jump to quite good and certainly adequate, respectively, at T4. The Sigma is already sharp wide open and just breathtakingly sharp at T4. The two Zeiss are nearly identical at T4 (as they should be, they’re very similar lenses). From a resolution standpoint, though, at T4 neither is nearly as sharp as the Sigma, nor quite as sharp as the Canon....[/quite]

What relevance does the CN-E version of the 85 f1.2 have to the performance of the new EF 85 f1.4 IS?

 

[Rowk]

I'm very excited about the reviews for this lens.
Thanks for the additional sample shots shown in this thread!

About that lens hood, I was wondering why there is no black velvet fabric inside of it?
It looks kind of cheap, like the ones Tamron sells with their lenses.
Doesn't that fabric make a difference anymore?

The fabric is a flocking material to reduce reflectivity even further https://en.wikipedia.org/wiki/Flocking_(texture). If you ever used Metabones MK4, you may remember when they "upgraded" the MK4 M to MK4 T just by adding this flocking thing http://www.metabones.com/products/details/MB-EF-E-BT4.

The Art has 95,6% hit? Wow, thats worse than my old 50 L. All other Canon L’s I’ve tried are 98,9% or better, 35 L II and 24-70 II was higher than 99,4% . Tested with a lot of data points. The Art lenses I had couldn’t get a result even

Anyone tried the AF consistency with the Canon 85 IS?

 

[SecureGSM]

Viggo,

are you sure? Well, let me explain.

95.6% number does not mean that 4.4% are "out of focus" shots. peak sharpness value at 1950 and trough at 1697. majority of shots are well over 1800. see the report.


in fact, as per report attached there is not a single shot that deviated from peak sharpness by more than 20%. all 54 of them are in focus. so that's 100% in your books.

And that's with peripheral AF points and crappy light too. not a centre one.

there is not a single lens I have ever calibrated achieved better than 98.5% QoF and that lens is Canon 35 F1.4 II.

24-70 F2.8 II, 70-200 F2.8 II, 16-35 F2.8 III I own and hundreds of other Canon and Sigma lenses I have calibrated over last few years never achieved QoF equal or better than 98.5%

Couple of points.

Canon CN primes are NOT great lenses at least in cinematography terms.

The EF 85mm f1.4L IS USM we have tested (only one so far) was very sharp and the AF very accurate, certainly worth the asking price.

Personally my favourite portrait lens is the EF 70-200mm f2.8L IS II USM its so versatile and the results never disappoint. However I will be getting the EF 85mm f1.4L IS USM for my kit bag in 2018 (still need to complete my Elinchrom light modifiers first).

«outer points” the very outer most non-cross or the last or second last crosstype?

Viggo, as per the test setup description:

Top left corner cross type AF point was used. Non cross type AF points switched off in menu as they are not really brilliantly accurate. Please note poor light level. (ISO 100, F1.4, T=1/30s average)

The light level might have something to do with it. I use 10-11 ev..
