Is there a way to get different aspect ratios on my DSLR?

Okay thanks, but how would you have 4 times the focal length? Are you saying to shoot as close as you can to 4k and then zoom it in post?

you can familiarise yourself how ML RAW 1:1 crop works in the ML forums and descriptions.
very short story: as the name suggests it’s a 1:1 sensor read-out as opposed to normal canon video mode where the full sensor is used but scaled down to FHD. 1:1 means pixel-perfect, so it’s a strong center crop and only parts of the sensor are used – the only way to record in such high quality because processing power and memory speed are very limited.

Oh okay. So you record in 4K, then it’s not using the whole frame, you are saying? But how is this possible on an HD sensor, since an HD sensor does not actually have enough pixels on it, to get up to 4K or even around 3K?

you do not understand how DSLRs work – they are for photography, so obviously they have a much higher resolution and pixel count on the sensor. if you take a look at the specs of, say the 5Dmk3, you see it’s around 5K. so, if you read out the full sensor you need to scale down to make recording work. magic lantern circumvents that and delivers direct read-outs but at the cost of sensor surface. magic lantern even adds HDR and dual-iso which brings the full dynamic range (14 stops – the most popular digital cinema cameras by ARRI only provide 13), to your footage, but it needs post-processing and does not work out of the box. this is another matter though.
in ML you can choose different aspects in RAW mode, without crop only 1920×1080 is the maximum though. you can shoot in scope or flat, which would refer to 1920×803 and 1920×1038 respective. for anything beyoond you would need to use crop and an extremely fast CF (not SD)

Oh okay. So you are saying that with MF, I can use a full frame and shoot in a 1:1 aspect ratio if I wish though?
