Do small scratches on lens front element affect the picture quality?

Travel tripod comparison: Manfrotto BeFree, Benro Travel Angel II and Gitzo Series 1

In this review I'll compare three travel tripods I've used.

Manfrotto BeFree (MKBFRA4-BH)
Benro Travel Angel II (C1682TB0)
Gitzo SER. 1 6X Traveler Kit (GK1580TQR4)

All three are kits, i.e., tripod and head.

Although they are in different price categories, it doesn't always mean that expensive is better. I'll share my experience using these tripods.
