Heliopan 71540H Overview

The Heliopan 40.5mm Screw-in Rubber Lens Hood is designed to prevent unwanted stray light from entering a lens by extending and shading its front end. This prevents lens flare and improves image contrast. In addition, since the end of a lens is extended when using a hood, you also get the benefit of extra protection from accidental impact to that lens's front element.

This lens hood is constructed with a rubber compound that is UV and temperature resistant, and the rubber material can be rolled back for storage or to convert the hood for use with wide-angle lenses. By rolling back the lens hood, its opening can be made to correspond with a wide-angle lens's angle of view so that vignetting is avoided.

A metal mounting ring connects the hood to a lens with 40.5mm filter threads and a 0.75mm thread pitch. The mounting ring also features corresponding 40.5mm front filter threads which can be used to accommodate filters, lens caps, or other threaded accessories.

  • Fits lenses with 40.5mm filter threads and a 0.75mm pitch
  • Blocks light from the sides of a lens's front element
  • Prevents lens flare and improves image contrast
  • Rolls back for storage or to avoid vignetting with wide-angle lenses
  • Double-threaded connecting ring allows a filter with 40.5mm rear threads with a 0.75mm pitch to be attached after the lens hood is screwed onto a filter or lens
  • Accepts lens caps
  • Provides protection from accidental impacts to a lens's front element
  • UV and temperature resistant

What kind of lens is this made for? I have a Minolta CLE rangefinder camera with a 40mm f2 lens with the same 40.5mm screw threads as this lens hood. Will this hood cause vignetting of the image or block the lower right corner of the viewfinder? I ask because I think this hood is larger than the rubber one made for the Minolta 40mm f2 lens.
Asked by: Richard
While Heliopan does not indicate any particular focal length for the Heliopan 40.5mm Screw-in Rubber Lens Hood as it is a generic lens hood, they do indicate that when the lens hood is in the fully extended position, it will work with normal focal length lenses, while when in its retracted position, it would be compatible for use with wide angle lenses. As the above is a generic lens hood, we cannot confirm if the lens hood would vignette with any particular lens. You may purchase the lens hood and test it on your lens, and if it does not work for your usage needs, you may return the lens hood for an exchange or refund within 30 days of purchase.

question

Will this vignette images at 16mm? This seems to be the right lens hood for using with the Sony E series 16-50mm lens. Will this cause vignetting of images at 16mm on say an alpha 6000?
Asked by: Nathan
Sorry, mine is mounted on a Nikon P7800. 28-200 so do not know about a 16mm.. it is a nice quality rubber hood and well worth the money. I would not advise a cheaper brand. Try asking on DPReview.
