Pokémon Brilliant Diamond and Shining Pearl will make you fight against the toughest trainers and gym leaders around, and high accuracy is critical to your success. Thankfully, we have the zoom lens and the wide angle lens to use to our advantage.
The zoom lens and wide angle lens are located in the southwesternmost area of Veilstone City, just below the gym. It is also close to where the massage therapist is located. In the lower left corner of the city, you will see a couple frantically trying to find a wide angle lens that the woman has lost. Nearby is a sneaky Skunky walking next to them.
Finding the wide angle lens is easier than you probably think. Simply interact with the Stunky and you will find the wide angle lens at your fingertips. Now that you have discovered the lost item, go back to the woman. The couple will then reward you with the zoom lens and the wide angle lens as a thank you.
The zoom lens increases a Pokémon's accuracy while being held if it has the second attack in line during battle. The wide-angle lens slightly increases the Pokémon's accuracy with no prerequisites. You can give your friend both items via the Bag menu under “Other Pocket Items”. Press A on the item and then you will be prompted to "Give to a Pokémon".
