Panasonic GH4 vs Sony A7R II in low light – Speed Booster Shootout

When you have a Need For Speed there are two people you can call – Shane Hurlbut or Metabones.

The Metabones Speed Booster adapters give us apertures as fast as F0.64 from the rare Canon EF 50mm F1.0.

The XL 0.64x version fits the GH4 and turns the scruffy 2.3x crop 4K into a shiny Super 35mm unicorn. F1.2 becomes F0.88.

The Ultra 0.74x version for E-mount fits the A7R II and turns the Super 35mm mode into full frame, with the benefit of 1 stop gain in low light and a further 1 stop gain in noise performance over the pixel binned full frame mode.

Samsung NX1 vs Canon C300 (image quality)

The Canon C300 (currently reduced to $11,500) was the $15,000 stalwart of the professional videographer, only recently did it have a compelling rival – the Sony FS7.

The Samsung NX1 is essentially a cutting edge 4K Super 35mm sensor in a mirrorless camera, recently given a video oriented firmware update which improves dynamic range and the available image profiles.

I was curious to see how the images from these cameras compared and I put my Canon 1D C into the mix as well.

Evolving Sony A7S Review (Part 1)

I’ve had the A7S for over a week now and can share my initial thoughts, even some firm conclusions. Here’s one I’ve come to already – the Sony A7S is the best consumer camera Sony have ever made.

For $2500 the video performance of the A7S sits between the FS700 ($8000) and F5 ($17,000) yet the full frame sensor lends more character and allows for groundbreaking low light performance.
