Why S35+?

Different cine cameras could have different aspect ratio, so there are some difference in size for various Super35 format. The OOOM can cover the bigger S35 (>33mm). For a RED cameras with S35 sensor, there would be more than 20 different types of aspect ratios (different coverage diagonals) and so its very important to know about which one you are using. We tested the OOOM on RED Monstro and also Arri Alexa. The largest format (aspect ratio) that we can cover would be:

Max. Coverage (RED) : Red Monstro (6K HD), Red Gemini (5K HD), Red Helium (8K HD)

Max. Coverage (Arri) : Arri Alexa Mini 4K UHD
