Couldn't be bothered to make a proper Z lens with a chip, correct sensor thickness adjustments, or correct focus/aperture rotation directions, and now this abortion?

It’s so ugly I kind of love it 😂

But yes, they need to start adjusting their optical formulas to anccont for sensor stack thickness for each respective mount like Consina do. Electrical contacts too of they want to stay ahead of other manual focus lens manufacturers. I like the rendering of the Simera 28 and 50 and I’d buy both of them in a heartbeat if they made those adjustments in a mark II version.

I don’t know if a 2x AF zoom is the move though. It would have to offer a meaningful advantage over the Nikkor 24-70/4 S and Sony 24-50/2.8 G for it to be worth considering. I’d rather they put that R&D money into coming up with something more unique.. say a WATE or MATE type triple focal length design. The Leica lenses were discontinued and nobody makes anything similar. Cost prohibitive perhaps.

'adjusting their optical formulas to anccont (sic) for sensor stack thickness for each respective mount'

So we hear ad infinitum, but I'd like to offer an alternative point of view and some material to support it. Because, let me tell you there are huge numbers of extremely happy users of M lenses who use the lenses on MILCs.

They don't want to photograph to Cosina's jam-packed production schedule, which is truly a wishin' and hopin' scenario (apologies to Dusty Springfield). I use the 21mm, 50mm and 75mm in M-mount on any of my Sonys with results you can see in this very forum, they are not hard to find.

So outfits like Thypoch don't 'need' to do anything at all to satisfy a large volume of people. It's become a purity spiral, something that now has a life of its own, in the US at least. But you can just choose to not buy these lenses, that's an easy solution.

It's a kind of dead end thread, a bit of a laugh for us, so let me elaborate some more, because I do think there are many silent observers of this matter. Starting with a question: do you think all the MILC mounts are more or less the same in terms of sensor 'stack' thickness? Read on:

Nikon Z Series measuring approximately 1.1mm to 2.1mm depending on the specific model and measurement methodology.
Canon RF Series falls in the middle, typically measured between 1.25mm and 1.6mm. Newer high-end models like the R5/R6 tend toward the thinner end of this range (~1.25mm), while older or entry-level models like the RP may be slightly thicker (~1.6mm).
Panasonic Lumix (L-Mount) generally has measurements for the S1 series often cited around 1.45mm to 2.4mm.
Sony E (A7/A9 Series) is known to have a thicker sensor stack (2mm-3.1mm).

These data come from an AI search which cites Lensrentals and Kolari as sources, A bit all over the place, no? It also looks pretty rubbery in terms of scientific accuracy too, lots of range and approximations. I mean, if it is that critical.

Does Cosina issue various 'accounting optical formulas' to address the very wide distributions *within* mounts? We would not want to see the Z users with 2.1mm thicknesses suffer unduly, nor the L users with whopping 2.4mm dimensions.

Now, of late, the greatest names in cinema and photography started retailing lens ranges for E-Z-RF-L cameras - very expensive lenses for the most critical people in the business. Do you know that each of Cooke SP3s, Zeiss Nanos and Leica Hektors provide *interchangeable mounts* for each lens they sell in these ranges? With nary a mention of image-damaging corner whatever.

They all actually tout the use of these pristine lenses on sensors with purportedly alarming variance in sensor thicknesses. As does Thypoch in their cine range of the Simeras: 'With standard M-mount adapters, Simera-C lenses can adapt to various mirrorless cameras (E, RF, Z, L, X mounts) for cross-system use.' Thypoch did this after they received user feedback.

Guess the mount that comes standard on the Cooke and Zeiss ranges? E-mount. They are surely going to run into all sorts of trouble going from E to Z - some will be shifting from 3.1mm to 1.1mm! Cooke even offer an M-mount fitting. They all need to contact Cosina for expert advice.

► philip_pj, are those data about sensor stacks verified by you in some way?
I ask as it is the first time I ever heard about the still camera manufacturer you mention having sensor stacks differing in thickness from one model to another. It's an interesting claim though. What not may happen with the performance by their own lenses this way?!

Maybe it also is a good opportunity to mention that lenses designed so also rays at the perifer parts of the projected image falls in a perpendicular, or near so, can perform very well no matter the thickness of the sensor stack. One can imagine that cine lenses designed for the PL-mount very well may be designed this way.

That the sensor stack thickness and both the distance of, and the size of the exit pupil relative to the sensor cause unwanted image degradation in some lens designs is indisputable. It’s precisely why Kolari, who you cite, are able to charge hundreds of dollars for thin sensor stack modifications. It’s why Fred tests M-mount lenses on both M-mount bodies and a Kolari modded A7RII. And yes, some lenses can be adapted with little to no issues, with normal-tele focal lengths being impacted less.

I’ll accept that sensor stack thickness may vary *within* mounts across camera generations.. I know NEX and the first generation of A7 cameras had thinner!? stacks compared to later models, but I haven’t heard the same of Z and RF mount bodies so I’d be interested to see the receipts. Your reference to different measurement methodologies gives me pause though.

Regardless, the issue being discussed is demonstrable. Many M-mount lenses suffer from increased field curvature, image softening, or colour smearing when adapted to E-mount, and a bunch of E-mount CV lenses perform sub-optimally when used on Kolari modded E-mount cameras vs unmodded E-mount cameras. Downplaying the work that Cosina do in adapting many of their optical arrangements by lens mount is just silly.

If the situation were reversed, and Thypoch were to adapt its lenses to the different sensors, we would regularly have to endure pages and pages of litany about the fantastic, unparalleled results that would surpass all other manufacturers. Guaranteed!😄

Sensor stack thickness differences aren't a "claim", Kolari wouldn't be doing thickness mods on imaginary data.

@philip_pj

I see you are again ignoring pushback and just continuing to spam non-sense. No real interest an actual discourse or intelligent back and forth. Here is what you define as an "ultra vintage" form PhillipReeve:

"this 21mm 3.5 features a modern optical design with ED, HR and aspherical elements and therefore also shows a good performance with high contrast and resolution from the maximum aperture and an almost complete lack of chromatic aberrations."

Why do you keep posting and poisoning Thypoch glass threads? I am assuming you are affiliated with them. Sad, you obviously know enough to know better than to state factually incorrect or such severely biased things. You're also damaging their brand. At least on FM. Perhaps you think you're winning ground by the incessant cheerleading and lack of objectivity?

Years ago, I didn't agree with you at times, but you weren't this biased. What happened?

Because more people would be buying them yes 😂

They’d sell even more copies if they had electronic contacts too.

Thypoch makes no ultra vintage lenses. Their optical designs are quite modern as is their optical signatures. The only exception really being the 35/1.4 which I don’t think is “ultra vintage” by any means.

The Kasana 21/3.5 is entirely modern except some amber flare and vintage barrel design.


I 100% agree the 21 3.5 Kasana is a very modern lens-

The amber coating and flare/sun stars make it a really fun lens to shoot. Its by far my favorite 21 I have used. If the 35 is the same, I will be purchasing it for a concert lens instead of using my 35 Cron-

For sure. I have a Contax G21 I love to death, so not it the market for a compact RF 21. But if I were, I’d try the Kasana 21. I had a CV 21/3.5 but didn’t love it.

Looks like this lens is a 16 elements in 13 groups design *exactly* like the Sony. Size and weight also very similar to the Sony.. I haven’t seen the optical diagram yet but I have a bad feeling about this one.. they might be straight up stealing the design :/

Just like their 28 and 75 where they “borrowed” designs from voigtlander.

No they didn’t. The Thypoch 28mm and 75mm f1.4 have completely different optical constructions than the Voigtländer 75mm and 28mm f1.5.

If they really copied Sony here, this would be a new thing for them. And not a good one.

It's the 21/1.4 where the optical design of Thypoch looks almost identical to Nokton 21/1.4.

Yes, you are right. My mistake. I mixed up things. I should have looked better instead of relying on my memory alone. It is the 21 1.4 that is almost identical as Juha also mentions.

I have come to believe that at least on Thypoch threads, Phillip doesn't post unless it is approved by Thypoch. I might be wrong but that is the way it appears. Perhaps he has just become so enamored with the brand that he has lost perspective but either way I basically ignore anything he has to say about Thypoch at this point.

My view is that although Thypoch has made some interesting lenses and I like some of their design decisions (often including FLE in their designs, high number of blades with quite round apertures stopped down but still with nice sunstars, caring less about corner performance), I have been annoyed enough by other decisions (not adjusting their lenses for sensor stack thickness, not including electrical contacts, variable spacing in aperture rings going from 1/3rd to half to whole stop detents, using up critical space on the barrel with only a marginally useful dot system to indicate depth of field) that I haven't bought any of their lenses yet. In general I would like a bit higher contrast from their lenses as well and I have zero interest in their concern with flare and the color of the flare their lenses produce.

Maybe some day they will include enough of the things I like and avoid enough of the things I don't like to entice me to buy one of their lenses. I try out a lot of lenses because I know that my own experience with a lens is the best indicator of whether I am happy with it in the long run, so it isn't a really high bar to get me to buy a lens to try it out. So far, however, Thypoch hasn't been able to strike a set of features that have gotten me to pull the trigger and at this point I doubt they will.

I am not really sure what his relationship is. But, given how Thypoch interacts with shooters behind the scenes (I know of a couple odd things from sources), given the youtube hype and the talking points are literally essentially the same and scripted, and their glass (I think they are good but nothing too special), I don't trust Phillip's wild claims or Thypoch's marketing/influencer army.

I think CV is a cut above them in terms of offers, innovation, ergo, IQ, build and character. CV just feels much more mature with their chipped, re-house per mount and mount optical optimization of glass. I also think Thypoch's cinema branding is goofy--at least for their still lenses. They aren't color corrected across the range, they have massive focus breathing and the ergo are the opposite of cine-lenses. At least in their C-line they have good ergo.

I am not convinced they can make high contrast lenses with good flare resistance and resolution distribution across the frame. So, might as well lean into "not clinical" vibe. Despite the claims, in the cine word, DZO lenses are a budget brand. If you look at the higher-end cine lenses, they offer high micro-contrast, good flare resistance even resolution. They older glass people like and convert has actual character, not modern glass that has the "organic look" Simeras have done. Arri and Zeiss offers filters and such for desired affects. I said the same with CV--until recently, they struggled making lenses with high-micro contrast and performance. In the last several years, with the arrival of their APO's and 50/1 and such, they really are dialed in.

I am not as impressed as others with the FLE choice--in the 35mm for instance, the FLE doesn't really do much because the lens is soft WO. There is not MFD on the CV 35/1.5 but the CV produces better results at MFD. You need to stop down to f4 for it to be punchy at MFD on the Simera. So what's the point of a FLE on that? On the 75 is seems to actually being doing something.

From my perspective, they offer a lot of hype and glass from 3rd party makers has gotten better in recent years. I really enjoy my TTartisans 40/2. But Thypoch still suffers from what I would say have marked many makers--low or moderate micro-contrast, copying the Leica ethos in IQ, optical designs and branding with a sheer lack of innovation or having their own unique offering) and bad flare resistance. Other lenses like this: the 7artisans 28/1.4, Mr. Ding's Noctilux knock off, LLL's remakes...

I still hold the 28/1.4 is their best lens cause it serves an underserved FL and shows they actually can make a novel design. I am interested in the new Thypoch 24-50 because it hopefully won't suffer from goofy hiccups like the dots, irregular aperture stops, larger size, amber flaring, infinite locks--essentially gimmicks. While the lens looks like a Minolta AF lens, if that's as far as gimmicks go, good by me. I am just interested in actual performance.

I have now used several of their lenses and I like them on balance, but like you, they don't quite strike my correct marriage of IQ, usability and specs. Maybe the 24-50 will change that. I am open to it!
