A Hoya 67mm FL-D Fluorescent Hoya Multi-Coated (HMC) Glass filter is used when you wish to correct for the greenish tone that appears when shooting daylight film under general purpose fluorescent lighting.  

NOTE: The FL series of filters alone does not always guarantee 100% correct color balance when shooting under fluorescent lighting. They are general purpose filters intended for moderate correction and will not, by themselves, necessarily provide perfect color rendition.

An FL-W filter is used to balance daylight film under warm white or white type fluorescent lamps. An FL-B filter is used to correct the color balance when shooting tungsten film under fluorescent lighting.

Fluorescent lamps burn at many different temperatures and often require more demanding filtration for exact results. For specific filtration and professional use, it is strongly recommended that a color temperature meter be employed along with Color Correction filters (i.e.CC30M) when shooting under fluorescent lighting. This is the only proven way to achieve exact color correction.

Multicoated to minimize reflection at the filter surfaces which reduces flare and ghosting.

Essential in any environment where ambient light source is fluorescent

As one of the premier filter manufacturers, Hoya filters continue to made from quality glass assuring the photographer clear, sharp and accurate images

Hoya filters consistently provide even color all the way through the filter; All surfaces are ground and polished to specific thickness and tolerances

Even non-multi-coated Hoya filters have one layer of anti-reflective coating applied to each surface of the glass; Hoya's single layer coating decreases light reflection off the surface from approx. 9% to an average of 4-5%

Q: 2. Has Anyone who owns this lens found a good quality plate that fits well?

Q: 3. What is the Nikon Warranty on a New lens? One year, two, or 5?

Q: 4. How is handholding this if it’s only being held while shooting (i.e. it spends most of the time in a bag/on a shoulder strap)?

A: The lens is much lighter than one would expect and the stabilization in it is phenomenal so hand holding shots is quite spectacular. Depending on the camera and how long you're shooting for it can get a bit heavy so I would recommend having a strap that slings from the body to the shoe of the lens for longer more comfortable shooting lengths.

Q: 5. Can I use this lens with my Canon R5?

A: You would need an adapter such as the Urth Manual Lens Mount Adapter for Nikon F / G-Type Lens to Canon RF-Mount Camera Body, BH # URULMAFGR. While autofocus will not be available, you can control the aperture on the adapter itself. https://bhpho.to/3Sxkosa

Q: 10. Hello, from Adelaide, Australia.I am seeking an external battery power supply for the Olympus FL-50R flash unit, which either plugs into the socket located at the lower front of the FL-50R unit, or the similar socket located on the side of the FP-1 Flash Power Grip. Olympus used to have a SHV-01 battery unit but is now discontinued. Do you have a replacement unit, such as a GODOX or similar, to provide this function? Alternatively, please advise if the METZ connector is the same. These unique connectors provide a dual power supply of 6 and 300 volts. Hope you can assist.Best regards,Geoff.

A: To power your Olympus FL-50R flash, you can use the Quantum QB 1 Plus battery. Please see the following link:http://bhpho.to/omPwABAnd you will need this cable. Please see the following link:http://bhpho.to/lTWL8uYour rates will vary from flash model to flash model but it should last for about 250 full power flashes or about 1000 in TTL or auto mode. And your recycle time will be about 50% faster when using the Quantum battery.
