you mean the canon has some magic pixie dust that makes a button work differently?
The connectors that go into the camera are cheap crap
What makes you think the canon isn't, or in any case, what is your proof that off-brand are?
don't have metal locking ring thing
I have no idea what this is because rebels don't have it.
and just don't fit as nice as the Canon.
Nonsense. I have 2 off-brand remotes, they fit as tight and snug as I would ever want.
They feel like cheap junk, therefore they are cheap junk.
Canon's 50 1.4 feels like cheap junk. Is it therefore cheap junk?
Besides, I've used a canon remote release before (a friend's), it feels pretty much the same as mine and makes me even happier with my purchase.
I've had my Canon remote release since the 20D came out and it is still working great.
I have had my 3rd party remote release since 2010, thrown it around, dropped it, and it still looks brand spanking new nevermind working great as well.
How exactly are you coming to the conclusion that all off-brand remotes are junk without having used all of them?
