Hi, Liam. Can you confirm that your replaced 300d still have no overheating issues when pointed up?
Why use ML still?
Color is a king. Adobe Camera Raw gives superb results (despite slight flicker sometimes) in terms of tone mapping, highlight roll-off and fine individual color controls. ML RAW skin is the best skin right out of the box. Afaik only ML RAW and RED with their RedColor and RedGamma have an option of "Instant LIKE gamma on raw" without any need of REC.709 conversion, hassle with log etc.
I'm using UM4.6 right now, but even this camera in raw mode with proper exposure and resolve debayer magic can't offer better color rendition for me.
Free lensing was a good option in my case. Strange bokeh and flares created decent dreamy mood.
Twilight zone meets commercials and black comedy. :)
