This pouch is for the 500mm f4 lens. Kinesis calls this a pouch but I call it a case since it is fairly stiff with heavy padding. Excellent condition. Usual Kinesis quality. Inside dimensions are approximately 18"x6.5" $60 PP gift including shipping to lower 48 states. BONUS: I will include for only $11 more a Kinesis long medium lens pouch (old style) for the 70-200f2.8 size lenses with purchase of the big pouch. Inside dimensions are approximately 10"x4.5" It is in excellent condition also. Such a deal: 2 Kinesis pouches for a mere $71 inclucing shipping! These are great pouches but I just don't use them anymore and I am cleaning house so they need a new home. EMAIL best.
