Well 75 mm with a crop factor of 3.9 is 292 mm so your estimated 300 mm was very close :D

I am still incredibly new to cameras and optics, could you explain what you mean?
Also Video 2

BiduleOhm:
I should have used quotes, sorry. The second part was for Nikon1.

@ BiduleOhm: I was more thinking about an actual 300mm Lens, Somewhat surprised then :)
@ RoboChair: So the Cronos has an quite small sensor compared to Cameras like todays DSLR And DSLM Cameras. 35mm FullFrame is something like an standard for focal Lenght and most people will convert their actual focal lenght in this case 75mm for the Chronos 12-75 Zoom @75mm into a Focal Lenght, which would give them the same Field of view on an 35mm FullFrame Camera Sensor.
Since the Chronos Sensor is 3,9 Times Smaller in Diagonal than the "Standard" 35mm Sensor size (Which is also well known from early Film SLRs) it will only record an part of the Same image, compared to an FullFrame-Sensor (further just called FF because Lazyness), if you where to record the same image with both cameras. Thats why it is called "Crop" or Crop-Factor. You could get the same image by using digital Crop on the bigger Sensor camera.
.
So, your lenses will apear to be way more "zoomed in" on the chronos, compared to if you would use the same Focal lenght. You will get the same framing (Field of View) using an 292mm (roughly 300mm) on an FF-Camera or an 75mm on the chronos.
.
To be honest, this could get confusing quickly for someone new to all this. And i am not realy the best at explaining it, hope you got something out of it. otherwise, or if you need more info, look it up on Wiki:
https://en.wikipedia.org/wiki/Crop_factor
https://en.wikipedia.org/wiki/Image_sensor_format (Chronos Sensor-Fromat is listed under 2/3")
https://en.wikipedia.org/wiki/Full-frame_digital_SLR
.
In a short: Your Lens will always be an 75mm for example, no matter which camera you use it on, but it can be for example an Long tele-Lens on the Chronos, a short Portrait Lens on an 35mm FF-Camera or even an Wide-Angle Lens if you use it on an Large format-Camera.
