100% Shootout: Canon 5D3/1D4 & Sony a6300 w/ Sigma 150-600 @ 150 & 600mm

[Vladdo]

As a keen aviation photographer, I'm always on the lookout for better gear. With the recent release of the Sony a6300 and sigma's adapter that can use sigma made canon mount lenses, my interest was piqued.

 

So in terms of raw numbers with a 600mm lens..

 

5D3 @ 1.0x = 600mm (5760 x 3840px)

1D4 @ 1.3x = 720mm (4896 x 3264px)

a63 @ 1.5x = 900mm (6000 x 4000px)

 

All images were shot as RAW and I've tried to keep all settings the same. Converted in lightroom at default settings with only adjustment made to white balance so it's the same across all images.

How is the autofocus speed on the a6300?

How is the autofocus speed on the a6300?

 

It's actually really fast. however.. if the scene is busy in PDAF mode, it does hunt a lot at longer focal lengths. But, it's early days yet, so I have every confidence that sigma will sort out firmware issues and improve upon what is a killer combo.
