I heart ny - S4-E18
Revealing mistake: Just after Big has left NY for good, Carrie leaves his apartment and is walking down the street. A leaf (that another mistake pointed out was digital as it was falling to the ground) is lying on the sidewalk. Carrie picks it up, but it is obviously an artificial one made from plastic and fabric.
Visible crew/equipment: When Charlotte leaves her apartment building on the way to the party, she puts on large sunglasses. You can see what appears to be camera equipment, in the reflection of the plastic lenses. There are two white squares, which look like a camera light and filter screen. (00:22:20)

Other mistake: At Steve and Miranda's wedding, Charlotte is holding baby Brady, who looks younger than a year (around 8 months) and is using a pacifier. But in 2 episodes prior, they celebrated Brady's 1st birthday and the actor who played Brady looked way older than the Brady at the wedding. I know they cast different kids, but it seemed as if Brady aged backwards.
