hello,
What will have greater impact on images quality, particularly in low light situations? Upgrading to full-frame camera or buying brighter lens (like Sigma 18-35, f/1.8) for my Canon 7d?..And logically if full-frame is 1.6 times bigger than crop-sensor, noise performance of full-frame should be 1.6 times better. ..is this true?
Regards and thanks,
Jitendra
