Hello friends and fellow cinematographers, Not sure if anyone have posted about this topic but here it goes... Other than being able to shoot RAW from the Alexa, practically and to-the-eyes and after all the proper post correction and all, is there a huge difference between raw from Alexa and the proress 4444 XQ from the Amira? I'm sure there is a difference, but is the difference too great or are most people just being an unconscious pixel-peepers? I feel much of the discussion have put too much attention and emphasize on this issues and on the argument of which is 'truely' cinematic or fitting for cinematic use and I just want to get a simple answer once and for all. Thanks! Dave

Hello my fellow cinematographers and filmmakers! I got a question to be clarified ASAP since I'm going on a shoot and in need of the answer =) I understand that Red camera has this issue where the crop factor is different as I change shooting with 4K to 2K. The crop will go from a APS-C size sensor area to a super 16 size sensor area. The camera is only using a certain part of the sensor as it records the set resolution. So the field of view of a 25mm on at 4K will be similar to that is of a super 35 but once it's changed to 2K then the crop makes the lens into a 80mm equivalent (math may not be exact, but you get the point). It’s troubling since the lenses will not have the same effect as different resolution is used. So I’m just wondering if Arri Amira/Alex has the same issue? Is the total area of the sensor (super 35 equivalent) going to be used as I change from shooting with 4K to 2K and 1080p? Does it also have this crop problem as Red? Simply put, if I use a 25mm on Amira shooting at 4K and then I change the resolution to 2K, then field of view of both should be exactly the same? Thanks so much for taking the time to answer this!
