NEW !!! Mitakon Speedmaster 85mm f/1.2

ZY Optics, the Chinese company behind Mitakon and Zhongyi lenses and adapters, has announced its new Mitakon Speedmaster 85mm f/1.2 lens. It’s an ultra-fast, manual-focus portrait lens that gives photographers an f/1.2 aperture without breaking the bank.

I wonder what it would be

$800 retail.

Interesting.

Maybe some $500~600 used after a few years. I like it.

Very best,

Man, a F1.2 lens would be tough to focus with modern viewfinders.

Did they say if it at least has an af confirm chip?

Well an EG-s focus screen would probably help. Also if the lens is any good at all, with a DoF that narrow you should then see it snap in and out quite crisply.

If you are lucky enough to have a camera with a changeable screen that would be great. For the 5d3 you would have to purchase an aftermarket screen and then perform major surgery to install it. I am sure this would void my warranty too.

Interesting. Is this going to be the first 85mm f1.2 lens for Nikon mount? I always thought there are technical reasons why it was hard or impossible to produce a quality lens with such specs for Nikon mount, unlike Canon's case. (And that's why third party manufacturers, like Sigma or Zeiss, opted for f1.4 instead, as the least common denominator across multiple mounts they have to support.) One obvious reason could be the fact that the rear flange diameter for Nikon is quite a bit smaller than for Canon EOS (which should make it harder to design super-fast lenses, as you have to bend light rays more to squeeze them into smaller mount opening). If ZY can do it, why Sigma can't?

I would be interested in the lens, I can confirm the EG-S screen is great for the 6D.
I have been in no rush to get a 85mm lens, the Canon is expensive, Sigma not as fast.
I quite enjoy my 100L for portrait shoots, but I would be happy to try one of these used.

I only three shots with the camera before swap the screen out. (arrived before the camera)
Best $22 I spent on gear. I love fast primes and it makes a big difference in the viewfinder.
If you have a 6D or a 5D II your should do yourself a favor and get one.

Those manual focus screens for Canon are even for AF shooters interessting - but most don´t know.
With the normal screen one does NOT see the right blur with fast lenses! So all those who use lenses faster than ~f/2.8 don´t see what they create in the viewfinder with the normal screen.

You're never going to see anything faster than f/2.8 through the viewfinder no matter which screen you install, normal or otherwise.

Why not?
When I use the EG-S screen I see a difference when I stopp down a (manual) f/1.2 lens to f/1.8 for example, with the standard screen not.
Without this the EG-S screen would not help much to focus f/1.2 or slower lenses.

The light passing to the viewfinder via the pentaprism effectively goes through an aperture which is smaller than the f/1.2 of the lens.....in essence, you're seeing a stopped down version of the image. You can detect a difference when you stop down the lens but it's likely to be that the reduction in light intensity allows you to better perceive the in focus regions.

A visit to their website showed this: http://www.zyoptics.ne​t …ter-85mm-f1-2-lens-dream/

Also on the website are a 35mm f/0.95, an 85mm f/2, and a 42.5mm f/1.2.

However, digital sensors may not see all of this extra light. Look at this link: http://www.dxomark.com​/Reviews/F-stop-blues.

Note - multiple visits to the first website above have shown me different lenses each time.

That sort of implies that going above f/2 is a lot of money for not a lot of benefit. Hrm.

so the charts on dxomark, the ev pretty much corresponds to f stop so an ev of -.2 drops a f1.4 to f1.6?

Hi Bob, with the pentaprism I look at the real image on the screen. You look through the pentaprism with a ocular. The ocular aperture can mimimize the brightness of the image, but no longer the way the DOF and bokeh is shown on the screen.
When the screen transfers the f/1.2 information to its back side, you see it even with a f/4 ocular for example.

When the micro-prims of the screen don´t accept light from f/1.2. but only from ~f/2.8 that DOF is not transferd to the backside of the screen.
