Stunning picture quality, even at high ISOs (though be prepared for bigger file sizes, even jpg are around 20 MB on max resolution, and the RAW's are 80MB and beyond)

I did try video mode at top quality with the Lexar Pro 2000X U3 card, and the camera didn't recognize it as a U3 card, so I couldn't use it yet and the card is going back

The quality of EVF is great - i don't miss anything that the traditional OVF from Canon provides.m) Adapted Lenses - With a cheap Sigma MC-11 adapter, I can use all my canon glass on Sony

Its slow-mo feature is buttery smooth, and the quality is exceptional

4K Video - Sony has far better 4k video quality than Canon

The ‘G’ line is also excellent though not of the superior quality of the G Master line

In terms of low light/high ISO capability, I'm getting top quality at

Great quality!

It fixes almost every issue the a7R II had: speed, viewfinder, speed, card slots, speed, build quality, and speed.

Very good quality and the seller is very responsive!

Absolutely amazing picture quality and the auto-focus will make you cream your pants.

Very nice build quality, compact but rugged

Truthfully, the D750 may not produce images as sharp as those the Sonys are capable of producing in good lighting, but the D750 with a 20mm or a 70-200mm Tamrom Way outperforms any Sony in low light--yes, including the A7RIII (the new one, that is).Anyway, the Sonys produce super sharp images with native lenses and non-native lenses with good adapters, but they tend to perform poorly in low light, relative to Nikons

IBIS technology is another huge advantage of Sony - you can pick super old (and cheap) lenses from ebay and they will be stabilized once you put them on Sony!l
