The User’s Review: Canon Grips GR-10 L, GR-20 and GR-30 for EOS 600, 620, 630, 650 and RT

These grips work as both grip and battery camber cover on EOS 600, 620, 630, 650 and RT. Without a grip, the cameras will not power on.

GR-10, 20, and 30

Actually, GR-30 should be the standard model for those cameras. But what are the differences among the grip models? I am answering this question with the images and table.

	GR-10 (L)	GR-20	GR-30
Grip	Large	Standard	Standard
Bottom	Long	Standard	Standard
Bottom strap eyelet	Yes	No	No
Hand strap	Optional	No	No
Shutter cable socket	No	Yes	No

GR-20 and Remote Release 60 T3

Finally, I should mention that GR-20 and GR-30 are the same in dimensions, except the shutter cable socket on GR-20. I have a mid-size right hand, GR-10 feels a little bit bigger for my hand to hold.
