I am pretty sure I will get either the 5DS or the 5DSR, but I don't know enough about which one to get and can't find that much information online about the low-pass filter. I've read a few places that with enough resolution, the low-pass filter is less useful. I'm still leaning towards the 5DS though because I read one post that showed the color issues without a low-pass filter. So, if you are going to buy one of the new camera bodies for sure, which one are you leaning towards?
