Photonis ECHO vs 4G+ Resolution Test

Side by side comparison of an ECHO tube and a 4G+ tube of similar resolution. This is a standard performing ECHO tube with higher than average FoM for ECHO tubes.
4G+ maintains better resolution and image quality throughout different light levels due to better parts selection and more stringent quality standards throughout the manufacturing process. 4G+ gives tangibly better resolution and contrast as the phosphor screens and fibre optic inverters are of noticeably higher quality than ECHO and ECHO+.

The Echos are holding up well!

Dual native ISO on A7S III is 12800. Looks better than 5000

He’s using a 40k machine that can control lux, this test is a billion times more conclusive than a outdoor test with a Samsung phone
