Chromatic aberration shows up in the trees and TV antenna.

No. I think you're looking at 4k with a small youtube window. I recommend watching the movie in full screen! The Speed Booster lens does not add any artifact, rather it increases the light on the sensor by improving the dynamic range and decreasing the noise.

Genio! So, if it works on Ursa it should also work on Ursa Mini Pro?! Can you share a photo of how it looks like? :)

Sorry, it works on Ursa Mini 4k and Ursa Mini 4.6k.
The Ursa mini 4.6k Pro is different, has an interchangeable mounting and ND built-in filter.

Hm, but interchangeable lens mount and ND filter should have no influence at all!? The lens mount is the same EF and ND filter does not interfere too, I guess?

The internal ND filters may be quite close to the mount thus interfering with the optics of the focal reducer ;)

Let me know when you got it working on a ursa mini pro!

This gadget could bring someone to choose the mini ursa 4.6k instead of the Ura mini Pro, since the Magicbooster turns the Ursa Mini 4.6k into Mini Ursa Full Frame Camera.
I do not know if it is possible to build it for the Ura mini Pro because the ND filter mechanism that could hurt or prevent assembly.
My limit is that to build an adapter I have to buy a camera each time because I need to have it in my hand for testing.
After I built the NX-L adapter on Samsung NX1 I wanted to apply my experience on a professional video camera and I preferred to start with the cheapest in the Pro industry.

Yeah I understand, well I already got the pro and a lot of users upgraded as well. The ursa mini 4.6k is a bit older, so the ump will be sold a lot longer, hence there will be a bigger market for it. So no reason for me to switch back, the ND's + IR are really handy. Yeah if you come to Belgium you can test on mine. But I reckon there are some other UMP shooters in Italy that can help you out.

In fact, I think that the variable nd filters can be added to the lens, while you can not add a focal reducer to Ursa Mini Pro.
The Ursa mini 4.6k is still sold new in many stores, with the price difference ($ 1,500.00) you can have an Ursa Mini 4.6k + Magicbooster and ND variable filter and you'll have money in your pocket ..

hi, isn't this a risk for the people funding this product-
