Wouldn't adapters of this type fit to use Canon lenses?

can be designed so that the additional battery can be stored in the handle, it would be very convenient

Interesting thing, only the reviews are not very good, but you can find something similar. Then it remains to ask the krontech team to make an application for us through which we could manage and watch, it would be much more convenient than going through the browser and entering an IP. Is it possible to make such an app for android and ios?

This is also suitable for 2.1? what version of the camera do you have?

Not very reliable connection to power the camera, it is better to use a v-mount battery

Unfortunately, we have decided to remove the 100kpfs feature because of the artifacts at high framerates (around 50kpfs or higher). Starting in the next update, it will no longer be available for the 1.4 or 2.1. The max framerate will be back to 40kpfs for the Chronos 1.4, and 24kpfs for the Chronos 2.1.

whether there will be an addition in 2.1 in the future.
50K fps or 100k fps, because this sensor supports up to 300K FPS

Tell me what affects the frequency of RAM and whether it can be replaced, for example, 1600 to 2400 or 2666. What does RAM installation from different manufacturers affect?

Hello again,

because nobody can visit me during easter time, I just shot all my painted easter eggs :D
And I also tried out the 100,000k+ Framerate of the 1.4. Very impressive! I will do a more detailed video of that in the future.

to remove all the artifacts you need a lot of light, a lot. Then 100k will look good, 2-3 led sources of 1000-1500w





you probably won't be able to remove the artifacts, but if you increase the light sources and reduce the sensitivity of the matrix, you will get a better image
How are you getting the 100,000 FPS frame rate? More info on the lens & lighting?

Hi there,

I use the 4.0 Beta version. This will allow for nearly 110.000 fps.

Lens: Samyang 35 mm 1.4 with a cmount Canon EF Adapter
Not that cheap at all :'D 500

Lights: 2 x godox sl 150W

:)

You can See the whole rig in my 40.000 fps Video in the beginning. Nothing changed that much since this day :)

Is it possible to control the camera from your phone using this adapter?
It might be possible. However it's way easier to just use the Wifi of your phone and a router/switch in the same network connected to the camera.

If you go to shoot in another city, taking a router with you is not very convenient, but connecting the phone directly would be very cool, the phone can also be used as a second monitor.
Do you have a way to check this? I haven't got my camera yet and can't try it out

they have a very low color rendering index, you need to understand how many watts they are

This is an SSD holder for the Chronos 1.4 and 2.1-HD. This accessory is invaluable when shooting DNG on the go; save speed is vastly improved compared to an SD card. The camera can write about 60MB/s to a SATA SSD instead of ~12MB/s to most SD cards. DNG saves at about 12FPS on the 2.1-HD and about 18FPS on the 1.4, at full resolution.

What is the maximum speed of the SATA connector? And in General, all the connectors through which you can write files, how can you find out their maximum recording speed? USB, SDcard.
camera 2.1

Or is it the maximum write speed of 12 MB / sec, regardless of the speed that the SD card can write
Not Quite sure, but i think its more of an internal Limit bevore you will hit the Limits of the SD-Cards or SSDs (There are sure some Pretty slow and old SD-Cards or drives that will limit Write Speed, but i am not talking about that...). At Least, if you have an reasonable fast Card or Drive, i would expect the Bottleneck to be more inside the Camera in Reading out The Data from RAM/ Compressing / Computing /Whatever happens else to the Sensor data inside the Camera.

My SDcard 95mb and 300mb

Use more light, because cameras like the Vision Research Phantom have noise when the sensor sensitivity is increased and use a lot of powerful light sources to compensate


Here is one example of the light:
https://www.bhphotovideo.com/c/product/1247485-REG/mole_richardson_6371_1600_watt_tener_led.html


As soon as I get my camera I will make myself powerful light sources for shooting to save on buying. At the moment, I found a 600W led chip, but I need to look for a more powerful one around 1000 watts
Also, wow, that is one expensive Lamp right there in the B&H Link.... just checked... 10k.   
I have an 1200W and an 600W HMI Lamp, but those will flicker for High Framerate Shots (anything above 50fps will Flicker pretty badly with that Lamp).So i will definatly need to get something powerfull with LED, cause Tungsten Lamps will just need crazy amounts of Power to be anywhere near as bright....


OK man
As soon as there is any news about the light, I will definitely let you know. Also, the led chips that I found at 600 watts are with a high color rendering index of 95, but I do not want to advise them yet, as soon as I do the tests, I will share links to them

For example, I will have 3 cameras and I need to launch them through the web interface at the same time, in 3 different tabs I can not do this, and through different triggers it is inconvenient
