just got the hoodman extender kit
I debated on it because of the price. It is high but well made and works perfectly. The hood has a quick disconnect from the platform and you can just hang it with the little strap when you need to go back to the view finder. Very well made and fit perfectly to my 6d. It has a + or - 3 diopter for the eyes and a 3+ magnification on the screen. The eye cup is fine even when wearing glasses'
