The 49mm, 780nm Kolari Vision Infrared Lens Filter 49mm 780nmfrom Kolari Vision Infrared Lens Filter 49mm 780nmblocks visible light up to 780nm from the light spectrum. It features uncoated glass in an aluminum ring with 49mm threading on both sides.

Unlike the 550/590/665nm versions of this Kolari filter, this 780nm version does not require a full spectrum modification to be made to your camera, but only as long as you use the camera mounted on a tripod and set it to shoot long exposures. Otherwise, a full spectrum modification is required. That entails removing the camera's low-pass filter and replacing it with a clear filter. Once that's done, this 780nm filter will work as intended. (Kolari Vision can make the modification for you at a cost if you send in your camera to them.)

A: Yes, the PH-RBB Lens Hood will work on the Macro-SMC-T 100mm f/4 Manual Focus M42 Screw Mount Lens.

Q: 2. Is there a cap to put on top of this hood? (Just like a cap on top of the hood of those Contax G lenses).

Q: 4. Hey! Will this fit my Pentax ME 50mm lense? Thanks, Danielle

A: The SMC Pentax-M 50mm f/1.7 (1977-1984) available with the Pentax ME 35mm Electronic SLR has a front filter thread of 49mm. You can snap the Pentax O-LC49 49mm Lens Cap in front of your lens.

Q: 5. who had tried this lens hood on the Sony Sonnar FE 35mm f/2.8 with UV filter attached?

A: The ansnwer is dependent on whatever camera is being used. The Sensei PRO 49mm Aluminum Lens Hood B&H # SELHM49 is for 50mm or longer focal length lenses on full frame cameras. As such, this hood will vignette. On an APS-C sensor camera, it has good chance of not vignetting even if used with a filter.

Q: 6. The inner ring is made of Metal?

A: Yes, the inner ring is made of metal. The hood folds flat to accommodate wide angle lenses by preventing vignetting at the edges of the image.

Q: 7. does this cap fit the Pentax 18-55mm lens?

A: No. For the Pentax DA 18-55mm f/3.5-5.6 AL WR Zoom Lens you would need a 52mm lens cap. http://bhpho.to/V8DGFL

Q: 9. Will this fit a pentax k1000 50mm

A: Most pentax 50mm lenses take either a 49mm or 52mm filter/lense cap

Q: 10. Can you use a lens cap with this lens hood attached? What size?

A: Hi Mackenzie.This is a fantastic product. I have one, and a B+W clear filter on all my lenses (mostly Zeiss). It makes the camera less intimidating, provides deep shade to the lens (better than the original), collapses at a touch and is very compact, and , to answer your question the original lens cap fits perfectly (at least for my lenses). To be perfectly clear, the filter screws onto the lens, the lens hood screws onto the filter thread, and when it is collapsed the lens cap goes onto the filter as if the hood were not there. I am sure it would be the same if you don't use a filter.The best thing is that even when collapsed it provides fantastic protections to the lens/filter surface, which is recessed about a centimeter, well away from sticky fingers and other hazards. As a result, apart from blowing off dust, the surface stays pristine and I virtually never need to clean a lens or filter.Highly recommendedPeter
