This is obviously not a fair fight. But the comparison is interesting as you get to see what the additional money buys you.

Two Red Raven Videos
We haven’t been mentioning much about RED’s products lately. They can be a bit expensive to kit out, but they’re still cheaper than a lot of other options and they are known for good customer service. Here are two videos shot on the RED Raven:
4K Lens Test on RED Dragon
This 5 minute video compares a variety of lenses, including several more often seen in professional use, on a RED Dragon camera.
RED Raven versus URSA Mini 4.6K versus Kinefinity Terra 6K
Kinefinity has launched the Terra 6k and 5K models ($6000 for the 6K model or $9000 as a package with many accessories) with 15 stops of dynamic range or 13 stops when in global shutter mode. These cameras use standard SSD drives and produce RAW or ProRes footage.

Thoughts on the RED Raven 4.5K versus the Blackmagic Ursa Mini 4.6K
You can save some money by going the Blackmagic route but both cameras are worth consideration. Both of these cameras take the image quality to the next level that in the right hands can hang in there with some much more expensive cameras.
10 Reasons Why the Blackmagic Ursa Mini 4.6K is Better than the Red Raven
10 Reasons Why the URSA Mini 4.6k is better than the Red Raven is the title of a thread posted to the bmcuser forum. Of course there is a bias towards Blackmagic at this forum but that does not necessarily make them wrong. This thread is worth a read for those debating between the URSA Mini 4.6K and the RED Raven.
We like both cameras but we wish a fully kitted-out RED cost less.

Rokinon / Samyang Lens Test on the RED Dragon at 6K
You do have to stop down for best performance, and 6K is a lot more demanding than 4K in terms of lens performance. Yet these lenses hold up stopped down showing once again they are a great value.
RED Epic Dragon Versus Arri Amira and Sony F3
An interesting comparison of 3 professional video cameras. Only the RED was shot at an ultra-high resolution in this test.
