A Tiffen 127mm FL-B Filter is used to correct the color balance when shooting tungsten film under fluorescent lighting.

An FL-W filter is used to balance daylight film under warm white or white type fluorescent lamps. Tiffen FL-D filter is used when you wish to correct for the greenish tone that appears when shooting daylight film under general purpose 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.

Q: 5. My specialty is photographing birds in flight. With super long lenses, I often lose shots because I cannot find the bird with the lens because the field of view is so narrow. Does someone make the equivalent of a hot-shoe mounted spotting scope for long lenses like the 800?

Q: 6. What tripod would you recommend with this lens as well as a Gimbal?

A: For use with a gimbal, we'd always recommend slightly taller since when aimed skyward, the working eye-level of your camera is lowered. Too low of a tripod and you'd have to bend forward to use. I'd recommend a series 3 or 4 systematic-style tripod from Robus, Gitzo, Induro, RRS, etc. for use with a gimbal like the Wimberley WH200 https://bhpho.to/3ow9kMh or Gitzo fluid gimbal head (may also be used quite well with spotting scopes) https://bhpho.to/3sfbmmi.
