The Vello LHC-ET83D Lens Hood for Enhanced Photographyis specifically designed for use with Canon's EF 100-400mm f/4.5-5.6L IS II USM lens. It is used to shade the front element of the lens to prevent lens flare, which improves image quality and contrast. An access window on the side of the hood allows you to adjust filters such as a polarizer without removing the lens hood. The hood mounts to the lens via its bayonet mount, and it also mounts in the reverse for compactness and storage. While mounted, it protects the lens from accidental impact.

Q: 6. Which is best the Sony LHP-1 Lens Hood or the Vello LHP-1 Lens Hood? How does the Vello compare to the one made by Sony? Is the Vello LHP-1 Lens Hood a screw type mount? Is the Sony LHP-1 Lens Hood a screw type mount? If you are also using a B&W filter are the edge of the image clipped on the Sony or the Vello?

A: Both the Vello LHP-1 Dedicated Lens Hood and the Sony LHP-1 Lens Hood connect via a bayonet-mount and do not use the filter threads. A standard filter can be used with either hood. Please be aware that if the filter has a wide construction (outer ring is wider than the filter thread size) it could interfere with the hood. A standard filter will work without vignetting.Both lens hoods are similar in design, made of machined-metal and will primarily do the same thing. The Sony LHP-1 does include a Soft Carrying PouchThe link for the Sony version hood is, http://bhpho.to/VN0PXn
