I have the 50 mm f/0.95 FF lens. I'm still trying to figure out what, if anything, to use it on.http://www.zyoptics.net/product/mitakon-zhongyi-speedmaster-85mm-f1-2-lens-dream/
f/1,2 for medium format !!!

Considering all of the third party lens makers flocking to the E-mount, I was wondering when we would start to see 3rd party products for the GFX/X1D. This particular lens doesn't plug much of a hole in the FOV range available already but it should silence the criticism about the lack of fast lenses. I might buy this thing just to support the notion there is a market for Fuji G Alt lenses.
Once you've done fifty, everything else is iffy.

One of the author's main points regards distance and wide apertures. I rented the Zeiss Otus 55/1.4 in the Nikon mount and found that I did not need to stop down in order to get landscape-type DoF (in focus across the frame, front to back @ f1.4) as long as the distance was appropriate. Of course, the Otus is one of the few lenses in the FF world that is able to pull this off.
I alluded to this in my previous post in this thread. Mitakon seems to be the first 3rd party lens maker to release a lens in a G mount. I would love for Zeiss to bring the Otus to 44x33 MF. Either the X1D or the GFX.
I don't think that's in the cards.
1) You're assuming that the reason it won't cover 33x44 now is the mount, right? What makes you think it will cover in a G mount?
2) If in an X mount, there will be no way to get scan times under 300 msec. That will limit the utility. If with a leaf shutter, it'll be a different lens. Maybe they can save the bulk of the design, maybe not.
3) It's not clear to me that the Otus 851.4 has better IQ overall than the Fuji 110/2. I think that it's inevitable that Fuji makes an 80-90 mm lens themselves, and expect Otus-level performance from that. Will people buy a more expensive, manual-focus lens instead?

What I am thinking about is the possibility of 3rd party lens makers producing lenses for the G mount & the 44x33 sensor in the same manner that makers make lenses for Canon, Nikon, Sony mounts. I thought it obvious I was talking about the mount & sensor coverage. Maybe I should have used the term Otus-like or a phrase such as lenses on the Otus IQ level.
Again, overly literal. I was not specifically speaking of Zeiss or of the Otus product (I assume Zeiss would give such a lens series another weird name); it was just an example. Personally I would be interested in lenses that covered a FOV not covered by Fuji, f-stops not covered by Fuji, specialty lenses not provided by Fuji.
Yep, it would hard to outdo Fuji in the IQ department. But, as the owner of the Mitakon 50mm f0.95, you were drawn to purchase a lens you surely must have known would have with inferior IQ presumably to have f0.95 although from your comments, you now have less interest in the lens since using it.

Gotcha. I was confused by your wording :"the Otus" in " I would love for Zeiss to bring the Otus to 44x33 MF". Although you have now raised the economic bar for Zeiss to do such a thing, since it's not just a matter of "old wine in new bottles", but a complete new lens design and manufacturing set-up, and the market is still much smaller than the CaNikon market which they managed to satisfy with the same basic Otus designs.
I wanted to see what all the fuss was about without dropping ten grand on a Noctilux. I'd used the Canon 50/1.2 with great success before, and I thought that this would be more of same. I wasn't ready for the increase in SA and LoCA that came with the Mitakon, and the combination of manual focus and paper-thin DOF proved to be, well, shall we say, challenging. It should work on the GFX with an adapter. Want to buy mine? We could pass this lens around like Christmas fruitcakes.

I would buy it if it were a G mount. I'd rather buy from you than buy overseas direct from Mitakon which seems like the only place to get one right now.
It's not only Zeiss I'd like to see producing lenses for the G mount. I'd like to see Sigma, Tamron, Voigtlander etc. get interested about MF. As you mentioned, a whole new line of lenses might not excite Zeiss and others until the market is larger. I was just trying to feel out members of the group regarding their interest in alternative lenses in the native mount.

Will the new A7 III have the same issue with Leica Lenses as othe A7 xxx cameras?
Do you think the upcoming GFX rangefinder will have issues with Leica lenses?
Do you think the upcoming GFX rangefinder will have issues with Leica lenses?
You're talking Leica M lenses, right?
I will assume so.
It will have the corner smearing because of the sensor stack thickness. It will not have the CFA crosstalk problem, like all the other a7x BSI cameras.
Again, I'll assume you mean Leica M lenses. It should have similar corner smearing issues to the a7x cameras, and perhaps slightly worse CFA crosstalk than the a7, since the pitch is slightly finer.
The 100 MP chip should eliminate the CFA crosstalk as an issue.

You have assumed right.
Hmm. The corner smearing concerns me a lot.
But, the corner smearing will still be there? On the GFX, after cropping out the vignetting, will this smearing be that much of an Issue?
Depends on the lens. 75mm and longer, there's not gonna be any problem, I think. Shorter than that, you should test first. Slower lenses do better than faster ones. Longer lenses do better than shorter ones. Retrofocus lenses do better than symmetric ones, which makes the WATE a winner (but not even close to being cost-effective).
I've sold all my M lenses except the 90 apo 'cron ASPH and the135 Apo-Telyt, so I can't test anything else on the GFX.

Laowa 17mm F4 GFX Zero-D
Third party options for the mirrorless medium format Fujifilm GFX camera are still somewhat limited—at least compared to more popular mounts like Sony FE, not to mention Canon EF or Nikon F. So it was a nice surprise to see Venus Optics release the 17mm F4 GFX Zero-D.
The 14mm F4 GFX is another of Venus Optics Zero-D lenses, offering a full-frame equivalent focal length of 13mm and a field of view of 113° with "close-to-zero distortion." The lens is made up of 21 elements in 14 groups, including two aspherical and three extra-low dispersion elements. Venus Optics claims this lens is "ideally suited for landscape, architecture and interior photography."

Unless the QA is exceptional, if you buy one of these, you're probably gonna want to test it right away.
I note the location of the entrance pupil is marked. Do they expect people to use this lens for panos? Or maybe it's to make alignment easier if you put it in a UW housing with a dome port.

This may end up being a cr@p lens (compared to Fuji lenses) but to me the exciting thing about this release is that another 3rd party lens maker has recognized a need for the GFX lens lineup. This lens extends the focal range of available native mount GFX optics while the Mitakon extends the aperture range. I had lamented before that the Mitakon didn't provide an FL that wasn't already covered by Fuji but this one does hence the reason for the placement of the post where I placed it. However, 17mm may be too wide and f1.2 may be too fast for my needs but at least these things are available to folks who need them. I think it makes owning a GFX that much more attractive. I'm waiting on one of the top tier 3rd party lens makers to join the party with native mount GF lenses i.e. Zeiss, Sigma, Tamron et al."The lens is made up of 21 elements in 14 groups..."https://www.dpreview.com/news/97856...ew-laowa-lenses-for-sony-fe-fuji-gfx-and-more

I don't have any problem adapting lenses. This is a manual focus lens, at least by appearance, and it also doesn't allow control of the diaphragm by the body (also, by appearance), so the only thing it can offer as a native lens is EXIF metadata, I think.This may end up being a cr@p lens (compared to Fuji lenses) but to me the exciting thing about this release is that another 3rd party lens maker has recognized a need for the GFX lens lineup.

And we already have the excellent Canon 17mm TS-E.
Still, more choice can't be bad.
