>>3545337if you are shooting a long exposure you should already be shooting at the lowest possible ISO anyway faggot.
>>the less light you gather, the more gain you need. If your sensor is half the size, you need double the gain.bullshit. Take whichever camera you have, remove the lens and put it on a bellows. Stitch to cover the entire image circle. Once its all put together, its exactly the same as having a large format sensor. Guess what, your exposure time is exactly the same. The images did not magically become brighter, noise did not magically get better. per pixel quality is exactly the same.
