Perfect holster for quick access. I have a Nikon d7500 with wrist strap and arca plate with 70-300 afp fx lens with hood in shooting position ready to go and it fits perfectly without utilising the extention. The set up is 300mm long. With the extention utilized it will take a longer lens attached or an 18-55 kit lens in the bottom. 2or 3 batteries, camera strap, lens care items and cards all fit in the pockets including a pair of 8x32 roof binoculars in the front stretchy pouch. The holster looks and feels good quality. Great design for versatile utility. Highly recommended.
