They can name the camera the "Chronos 2.5" based on the GSPRINT4502 data throughput.

Chronos User Discussion / Re: Sale Chronos 2.1 FULL Setup + Optic (Thailand, Bangkok)
« on: May 15, 2024, 11:50:55 AM »
I see. Sorry about your experience with Krontech. They've been pretty responsive and helpful to me. Enjoy the Freefly! It looks like to be a great camera and thanks for the sample! I would really like to test out their Chronos Q12.
I'm hoping Krontech can make a 2/3 sensor 2K 3000 fps camera that is around $6000. I feel like $15,000 is still a lot of money for the average joe. $6000 would be perfect for a smaller 2/3 sensor I think. I still think there is a market for a 2/3 sensor instead of the 4/3 or APS-C sensor. Greater depth of field is something I would want and there are a few sharp 0.95 lenses (Laowa, Meike, ie) in case you wanted to get more shallow DOF with a smaller sensor. Would not mind if they had to cut corners with record time and RAM (two - three seconds is perfect for me) for it to be cheaper at $6000. Gigapixel does indeed have a 2K 3000ish fps 2/3 sensor so hope they use it.

Why not go for the Chronos 4K12?

Here are a few settings the Chronos 2.1 can achieve near 40,000fps
HRes VRes FPS 1920 20 40496.8 1280 32 37745.3 1024 38 39787.8 800 52 39745.6
Would you be able to post video samples of each resolution?

Chronos User Discussion / Re: Chronos 1.4 and 2.1 lowering bit depth to increase frame rates?
« on: December 29, 2023, 07:58:41 AM »Lower bit depth data must be physically recordable by the cameras' sensors. In the event that the sensors are only meant for 12-bit capture, it could be challenging to achieve lower bit depths using firmware alone.
Yeah true.

« on: December 27, 2023, 08:00:58 AM »yes the answer you have writes is perfectly fine
Not really, because this shows the 2019 revision has it at 18mm and 18mm but the 2020 revision as 15mm X 15mm which would not make sense.

Chronos User Discussion / Chronos 1.4 IR Filter Dimension Size Confusion?
« on: December 27, 2023, 07:17:07 AM »
Hi all, I'm seeing different dimensions for the IR filter size (See below links). Some documentation shows it as 15mm X 15mm, another shows it at 18mm X 18mm and 24mm X 16mm. What would the filter size be for a Chronos 1.4 received in 2018?

Is the square sensor of the Q12 made for all the 9-16 format requests that we get all the time?
www.ronaldkoetzier.com
You should have more flexibility for cropping to 9:16 when using the Q12 because of it's squarish sensor.

Chronos User Discussion / Future Camera Idea Krontech: Chronos 2K but using a 2/3 sensor for lower cost
« on: December 20, 2023, 06:57:57 AM »
Just an idea. Some of us like the smaller 2/3 sensor form factor as we can use modern sharp 0.95 and 1.2 lenses (Laowa Argus, Meike and Nokton) at their wider aperture receiving more light into the sensor while keeping a greater depth of field for easier focusing compared to larger sensors. And I'm guessing by using a smaller sensor and some other cost cutting measures (ie. cutting the maximum record time to 3 seconds which would require less RAM), the camera can be more affordable. Looks like GPixel has a 2/3 2K sensor (see below). Just a thought. Was thinking this can maybe be around $5000-6500 as the lowest affordable option for Krontech. At this price point, I think more people would buy.

Some key specs:
"GSPRINT4502 is a 2.5 Megapixel (2048 x 1216), 2/3” (φ10.7 mm), high speed image sensor designed with the latest 4.5 µm charge domain global shutter pixel. It achieves more than 30 ke- charge capacity and less than 4 e- rms read noise, with dynamic range of 68 dB which can be expanded using a multi-slope HDR feature. Utilizing an advanced 65 nm CIS process with light pipe and micro lens technology, the sensor achieves >65% quantum efficiency and < -92 dB parasitic light sensitivity.
GSPRINT4502 can achieve extremely high frame rates up to 3460 fps in 8-bit mode, 1780 fps in 10-bit mode or 850 fps in 12-bit mode, all at full resolution. With 2×2 on-chip charge binning, full well capacity can be further increased to 120 ke- and frame rate to 10,200 fps. GSPRINT4502 supports vertical and horizontal regions of interest for higher frame rates. GSPRINT4502 is perfect for high-speed applications including 3D laser profiling, industrial inspection, high speed video and motion analysis."

Chronos User Discussion / Re: Chronos 1.4 Footage Thread
« on: December 20, 2023, 06:50:27 AM »I use the 7Artisans f/0.95 35mm MFT lens. I usually film at f/0.95 or f/1.2.
I have a Meike 35 0.95 lens as well and it's pretty sharp at 0.95! My Meike 50 0.95 is a bit soft low contrast wide open but not too shabby. It sharpens up at 1.2 and up. One of the benefits of the smaller 2/3 sensor is we can use these wide open apertures as the DOF is greater and more forgiving in getting the subject in focus.

Chronos User Discussion / Sony C-Mount adapter Plate for older Chronos models
« on: December 14, 2023, 09:35:07 PM »
I see the new 4K12 and Q12 have the option for a Sony E mount adapter plate. Can the 1.4 and 2.1 get that same option as well?
