I remember seeing a movie a few (at least 3 or 4) years ago in the cinema. But I can't remember the name or the exact details, which makes it hard to search for online.
It was in a near future world where aliens were present on earth and quarantined into into areas. The movie focuses on a couple who enter the quarantine zone, I think to take pictures.
You don't see the aliens much, but I think they looked like metal Giant Octopus or Squid. It was set in a jungle environment and I'm pretty sure it wasn't a big hollywood style movie, but shot on a lower budget.
