Allow eggs to stand at room temperature for 30 minutes. Meanwhile, grease and lightly flour a 10-inch fluted tube pan; set aside. In a medium bowl, stir together flour, cinnamon, baking soda and salt. Set aside. In another bowl toss apples with lemon juice; set aside.
In a large mixing bowl, combine granulated sugar, oil, eggs and vanilla. Beat with an electric mixer on medium speed for 2 minutes. Add flour mixture and beat on low speed just until combined. Fold in apples and pecans. (Batter will be thick.) Spoon batter into the prepared pan.
