The End (1) - S6-E17

Revealing mistake: When Desmond moves the rock, Smoke-Locke and Jack fight outside the cave while an earthquake shatters everything. Watch the leaves around and you'll notice that they don't move at all, giving away the camera effect. This also happens later on when Hugo, Ben and Jack are about to fix the cave of light.

Lighthouse - S6-E5

Revealing mistake: 6-05 - The Lighthouse: While Sawyer and Locke are climbing down the ladder, Sawyer's stunt is noticeable because his shirt's colour is different, his hair is darker, and the sweat stains on his shirt disappear.
