Question to those who moved from crop sensor to full frame camera-low light Perf

For the pure question of low light performance, from everything I have read from Dx0 etc. The D610 and D800 are 1.2 stops better and the Df is at 1.4 stops faster.

 

I had the opportunity to shoot a D3S today. Great camera, super fast and responsive with a great buffer, but it would not work for me. The resolution is just too low..
This is with the D3S.. Nearly 100% crop 3 MP

This is with the D7100 About 50% crop 9 MP The ISO was actually twice as high on the D7100 (1100 vs 560 on the D3S, I wasn't in the exact same spot)

The speed was pretty sweet though..

So for now it will be the D7100. Hopefully next month will bring a new DX king...

 

I switched from the 60D to the 6D, mostly for doing astrophotography. I noticed a HUGE difference.

 

Just do it. It's worth it. I'm in love with FX already, and I've only had it for 4 days...

 

I hear ya!

Noise looks roughly the same on my D700 at ISO 6400 as my D300 does at ISO 1600.

 

Wow those flight shots are nice. I see they were shot at iso 2800 which let you shot at 1/2000 f 7.1

 

This doesn't make any sense how in the heck can the pics look the same when one is a stop more exposed.

 

The sensors have different size... That's why.
The full frame sensor collects more light than the crop sensor, and needed 1 stop less light to get the same exposure.

 

Huh?

You mean full-frame users need to learn the Sunny 11 rule?

 

No.
Sunny 16 for FF, as always.
