We believe that a good-quality, high-resolution camera should be able to provide a very detailed video picture. That requires a good viewfinder, a small and low-res image sensor, and a fast lens. We believe that an ISO-equivalent-with-a-good-follower-of-highlight-pattern sensor and f/1.8 focal length should also be required. If you buy the right image sensor, the camera will take good pictures.
A few considerations:
Do you want to take video at ISO 100, 400, 800 or 1250?
A typical 4:3 ratio of video image to sensor size produces very fine details, especially in darker areas. We are more concerned with ISO 100, 200, and 400 than at higher ISOs, which usually means smaller and less sharp images. To get good results at lower ISOs, we have recommended at least 1:1, 1:2 and 1:3.
Do you want to have more or less noise?
At higher ISOs, more noise can look more like a black/white scene as well as blurry or hazy effects. This means less detail in dark areas and some black-and-white effects in images. But these effects are limited at low ISOs, so if the subject is not being lit, you often get a higher-quality image. At ISO 400 and 800, you have less noise.
What is the color gamut of your camera?
Camera manufacturers advertise colors as a way of getting people to use the camera again for video purposes. Unfortunately, the color gamut of many cameras is not as good as advertised. To get a decent image from your camera, it must have good color. The human eye cannot see everything accurately. Thus, the good camera always has a wider color range.
In our view, the Cinestar VX-S provides a usable color gamut.
Can the Cinestar VX-S drive lenses to ISO 100, 200 and 400?
At the lower ISOs, the Cinestar VX-S is not good at delivering wide-angle lenses. At ISO 200, it only works with f/2.8 (fisheye lenses) and f/14 (conventional lenses) to produce wide-angle images that are too wide to photograph as close up or as far up as possible. But, in the upper ISO limit, the lens quality
