There’s a motive that gear just like the ARRI ALEXA are chosen for high-end productions. That isn’t to say that inexpensive gear can’t produce photos which might be on par with gear a number of occasions its price – it completely can.
It’s nonetheless good to see a few of these choices put face to face. Immediately we’ve one such comparability from filmmaker Blaine Westropp. He took an ARRI ALEXA Mini LF and did checks in opposition to a Sony FX3. There’s a worth distinction of tens of 1000’s of {dollars} between them.

Each cameras are set to ISO 640, 5600K, and with no tint. The lens was a DZOFilm Vespid 35mm T2.1 used broad open with an ARRI .3 ND and a 1/125 second shutter pace. Additionally the identical between the 2 cameras is a UHD 4K (3840 x 2160) decision. The place they differ is within the codec and gamma. ARRI makes use of ProRes 4444 in Log-C whereas the FX3 is inside XAVC S-I with S-Log3.
This was all with the lighting of the scene, which options massive home windows within the background successfully backlighting the topic. It is a powerful scene to deal with effectively as soon as graded, and Westropp aimed to start out clipping the highlights barely to see how they’re dealt with. In Rec.709 there was slight clipping however in log the data was retained.

The FX3 delivers by way of pure picture high quality. Loads of dynamic vary and respectable colour dealing with all through the entire scene – each ungraded and graded.
The ARRI ALEXA has some delicate variations and seems to have a barely extra impartial colour, however that’s an enormous soar in worth for a minor achieve. Don’t get me unsuitable, these variations matter, simply to not your on a regular basis shooter.
What’s curious is that Blaine factors out that it’s tough to match the 2 cameras. So, whereas the FX3 is an incredible digital camera, it won’t be the most effective if you’re aiming so as to add a B digital camera to your ARRI package.
