GGS (or GCS) glass screen protector - fits very neatly and does a good job.
Not too expensive either if you get them off the 'bay. Plastic film type are pants in comparison.
Don't you have to stick that on, though?
I have had a cracking set on mine for 6 months, they haven't scratched, can't be seen and haven't peeled at all.
Doesn't the 7D come with a screen protector already fitted?
Got a Giottos glass one for my 5DMkII - it's excellent. Cost about £15 from Amazon![]()
