Thanks.
On 25mm f0.9 I've heard good things from number of sources on the Mitakon for m4/3, it performs quite the same on tests and way smaller-lighter.
It reminds a M glass and apparently well build.

Don't forget the SLR Magic 25mm .95 as well, also a great performer and a "cinevised" lens.  I've used this for many years now.

Mmmm. Bad news. I really like the small form factor of the m4/3 lenses and thought it could have been an elegant solution matching the camera size philosophy. Now Chris cutted me the buzz  ;D not because AF doesn't work, I expected it, but because MF is a PITA with m43 lenses.


The thing is when you use native MFT glass, you tend to get much better optical performance than speed boosted or adapted 135 format lenses.  Remember MFT was designed to be allow telecentric lens designs and 135 format glass is / was optimised for different purposes.

Also, no adaptor, less interplay of mounts, usually smaller and better performing.

And MFT is very mature.  SLR Magic, Voightlander, Veydra etc etc as well as Olympus, Panasonic / Panny - Leica as native lenses.  Even other obscure companies like DJI, Laowa, Rokinon, Samyang, Mitakon, Ibelux have made native MFT mount.  Sigma too have done in the past.

Olympus 25mm 1.2 MTF charts...
"This is actually very good for an f/1.2 lens, much better than the Canon 50mm f/1.2, for example. It maintains excellent sharpness in the center half of the image. Itís still quite sharp, although with some astigmatism, out to the edge."

Comparing Veydra primes to Zeiss CP2's
"If youíre a CP.2 fan, youíre going to have to talk about the look of the lenses, or how they handle, or something similar to explain why you like them. Because, to be quite blunt, the Veydras just kick some serious resolution butt in this comparison. To be fair, though, Zeiss CP.2s have never been about absolute resolution. On the other hand, when you move up to 4k and eventually higher footage, the resolution is going to be more important than it was at 1080p, especially on smaller sensors."

Here's a pretty good list of native MFT lenses. Still doens't list SLR Magic (one of the most interesting manufacturers in my view) and Veydra.

And Veydra themselves

and SLR Magic https://www.bhphotovideo.com/c/buy/Shop-by-Brand-SLR-Magic/ci/4/phd/3888479510/N/4294255798

I have no affiliation with BH, but I have a close relationship and have consulted with both Olympus, SLR Magic and Blackmagic Design.

I also own Veydra's, Zeiss CP2/3's with MFT mount and most Olympus SLR Magic and Pananasonic MFT lenses

That is the point.
Thanks for those infos John.
