LensTip tests the brand new Sigma 85mm f/1.4 Art - sharpest lens ever :-)

[Jopa]

My experience is similar. My 35A is 99% accurate on my 5dsr, and 50% on my 7dii. (I don't have a dock, I do have focal.)

Any idea why?

I have a bunch of other lenses and they are pretty consistent on the 5dsr. I also asked CPS if there are any compatibility issues 5dsr + 70-200, they said "no" and advised to send both the lens and the camera in. I would totally understand if the lens would be inconsistent on another body, or 5dsr would act funky with other lenses, but that's just one combination, like the camera and the lens hate each other Magic...

I think it's just the nature of the beast. Manufacturing tolerances in the lens, the lens mount, the sensor mount, the AF unit, etc. all play together in affecting performance.

And to think the 300 is only 25 times the money of the 85 8)

Which canon 300mm (cine lenses notwithstanding) costs $30,000?

A used 85 f1.8 here is 2000kr and the 300 f2.8 L II is way more than 50.000kr, so I was being conservative.

My 70-200 f/2.8 II auto focuses extremely well on my 5DsR, no issues whatsoever. I expect you have an issue with your specific body and/or lens.

The body has no issues with other lenses, and the lens has no issues with other body. I'll send both the lens and the body to CPS early next year, right now just don't have time for it. The 70-200 stays mostly on the 1dx2 (I feel like they are made for each other ), so I can wait.

P.S. seems quite conclusive to me.. Order placed. Total: AUD$1,135.00 (USD850.00)

Yikes, it's £1199 here!

Pretty good
At least in the center the Otus is better, I'd say....but the Sigma is better in the corners. That's pretty amazing

Would still buy the Milvus, been looking at it lately. Compared the Art and Milvus I do not like the dark purple numbers with the Sigma that should be black.

Wonder how the 85 F1.4 L but be priced, between the Otus and Milvus somewhere I guess.
