I wouldn't be concerned about Global Shutter.
But TOS for depth maps I have wondered about if that technology is compatible with existing lenses. Anyone know?
What is «TOS»?

TOS is short for 'Time Of Flight'.
It is used to do an accurate depth map which most likely will come to 'big regular' cameras as well. It is already on the mobiles for better computational photography and also better subject recognition.

in essence totally irrelevant at this time and for some time.

I think that the 'totally irrelevant' statement depends on what value you put in the term 'this time' and 'some time'.
Many high end mobiles are already now delivered with TOS sensor functions. On regular cameras it would for example help with producing a good looking fake bokeh by creating a better depth map which would be a competition enhancing function for slow (kit) zooms. Especially on crop sensors.
Also it would help with better AF tracking on all type of objects and for the Face/Eye-AF on people and animals (which is a form of object tracking).

yep take the creativity out of creativity.
this is not new. its been around for a bit.
computational imaging takes it away from the so called photographer.
now we are talking about the global shutter and its future in still photography. it resolves a technical issue not a so called creative one.
i really haven't found the use of eye based AF on humans or animals to be a great step forward. an amusement possibly.

I'll stir the pot some more.
The move from DSLR to mirrorless allowed for a change in lens design, for the better. Without the mirror to have to fit inside the body, the first element of a lens could be closer to the sensor, allowing for smaller designs. For example, the Canon RF 28-70 F2 would have had to be much bigger if designed for a DSLR.
Global shutter, as I understand, might eliminate any need for a mechanical shutter. Not having to fit a mechanical shutter into the body means, you guessed it, another opportunity for lens re-design towards the even smaller.
Maybe this would make little business sense, as some suggest, for Sony to do right now. But, it will happen at some point. Some extreme speculation would be that Sony introduces global shutter first in a new medium format sensor body. Who knows..

Lenses will not provide dramatic increases in photographic capabilities going forward. With computer generated design and manufacturing almost all lenses are of very high performance.
It will be sensor, processing, and AI advances, that move photography forward. Sony has no need of a new mount to do this.

My hunch is that global shutters are at least 5 years away, probably longer. The increase in required processing capability and related power demand is significant, and it surprised me that Sony did not even improve its stacked sensor in the 3ish years between the A9 and the A92 (beyond some reported tweaks to the s/n ratio). That’s as close to a global shutter that we’ve seen so far and its lack of evolution makes me wonder if it’s a design dead end and Sony’s gone back to the drawing board

I think ToF sensor would do well on fixed lens cameras, but it would only be truly useful if the captured data could be embedded on RAW files

Today Vazen has announced the new 28mm t/2.2 1.8x Anamorphic Lens for Micro Four Thirds cameras. You can preorder it now at BHphoto (Click here). Press release: System Lens 2.1 SoftwareShenyang China, Feb 10, 2020 – Vazen, a new Chinese cinema lens brand, has announced the pricing and shipping availability of the Vazen 28mm t/2.2 1.8x Anamorphic Lens for Micro Four Thirds (M43) cameras. Vazen had previously launched the 40mm t/2 back in Cinegear 2019. Receiptbox 2.3.1. The new 28mm is the 2nd member and the widest of their 1.8x anamorphic line-up. The whole set will contain 3 focal lengths (28mm, 40mm and 65mm) and the 65mm is expected to be out in a few months. Unlike the 40mm, the new Vazen 28mm features a super compact and lightweight design. Weighing merely 1.59 pounds (0.72kg), it is currently the world’s lightest 1.8x anamorphic lens. Its compactness allows the lens to be used on gimbals or even handheld shooting without a rig. The lens is designed with a 77mm front filter thread for installing ND filters or diopters easily. The entire lens is built up of aluminum and the independent aperture and focus rings are incorporated with 0.8 mod cine gears. System Lens 2.1 SystemAll the Vazen 1.8x anamorphic lenses feature a front anamorphic design. It delivers a butterly smooth oval bokeh, signature blue, but not over saturated, horizontal flare and the widescreen cinematic look. The lens delivered outstanding sharpness, even at wide open, which is unmatched by other anamorphic lenses with the similar squeeze ratio. Similar to other wide anamorphic lenses, the 28mm delivers a relatively cleaner image than its 40mm counterpart and the coming 65mm is expected to have the strongest anamorphic ‘character’. System Lens 2.1 0Vazen chose to adopt a much more complicated 1.8x squeeze design instead of the 1.33x as it creates a much more cinematic look. The 1.8x also produces a cinematic widescreen 2.39:1 aspect ratio to your image when capturing with 4:3 ratio sensors like Panasonic GH5 and Z-cam E2.
It also works with the new 2.8k anamorphic mode on Blackmagic Pocket4k or capture open gate via an external monitor. The lens features a ultra-wide 72° horizontal field of view. The closest focusing distance is 2.7” from sensor. |
