In real world situations.... I really don't think there is going to be any aliasing situations. I just downloaded Philip Blooms test video and it looks amazing... resolving the tiniest of details with no aliasing on anything. Charts are stupid.
Anyways though, even if on a chart the C300 resolves a few more lines... which it really isn't showing when you look at it... why would people still chose a 5 year old 8-bit codec for 5x the price? It makes no sense. Supporting smaller companies (especially when they have the superior product) like BlackMagic is the best thing we can all do for everyone right now. I mean come on, this is their first camera... and it's giving us 2.5k RAW for $3000!!! Canon is re-hashing 5-year old technology, that sells for $2500, adding a few zeros, and has showed no signs of stopping... All of this canon fanboy-ism I've seen on other forums makes no sense at all. Most of them are just most likely looking for reasons to justify their $15,000 purchase... and discredit people from using cheaper more affordable tools.
People with no talent or creativity that still want to be in this industry either have to rely on "door holding" or "brush-holding". The later is basically gone away this year. This is why people are hating on the BMCC. Cheers!
