Thypoch Simera-C + Alexa

February 2, 2026

In a sea of what seems like an exponentially rising frequency of lens releases, a few here and there catch my eye. A wild price and physical size, for lenses that cover beyond full frame and have a T1.5 aperture. I had to take a closer look. I have also been using them on the hasselblad X2D. More on that soon. At this point, I assume that most people on this page came from the YoutTube video I posted. If not, you can find that here: https://youtu.be/0AUxNESc1r4

One element not found in the video was focus breathing. These lenses breath. I did not intentionally leave it out. I will add GIFs below that show the breathing, and I'm sure you can find videos that show it as well. Focus breathing is not something that really bothers me. One person mentioned that the distortion changes depending on where the focus is set, for example, it can go from barrel to pincushion when pulling focus from far to near. I never noticed this when shooting (outside of a diopter shot), but will include examples of this below.

The lenses were mounted on an Arri Alexa Mini LF, with the Thypoch M mount that I put on the Alexa:

Onto the Leitz Hugos. I almost didn't want to compare the 2 sets. I felt that once I saw them side by side, there would be such an advantage with the Hugos that I would want to turn all of my focus to them, but.. I was pleasantly surprised. More-so that I just enjoyed the look of the simera-c lenses and less that "they look like Hugos," but they do share characteristics.

And here we can see both lenses focused to 15 feet:

Onto breathing and distortion. I will start with distortion.. I am only showing this because someone in the youtube comments mentioned it to me and I rarely see this on prime lenses. Here is the 21mm lens focused to infinity, and then focused close:

See the sides, the door frame and the door. The distortion slightly changes when pulling to close focus.

You can see it in motion (as well as the breathing) here:

In general, this is not a huge problem in my opinion. In a shot like the shot above, maybe slightly peculiar, but after using these for months and on one commercial job, I never noticed this. Less noticeable when shooting 2.39:1 or 16x9.

I significantly enjoy the lenses the more I look at footage. The look you get is very cool, and they are about $900 per lens, which is just wild to me. Here is the 75mm at a 5.6/8 split:

And at 1.5:

There are a lot of times that I enjoy when the vignette comes in as you open a lens, which happens on most lenses. There are projects I do where I want even exposure edge to edge, and there are projects I do where I want that vignette. The simera-c lenses bring in a nice looking vignette wide open, while remaining clean and even stopped down 👌.
