The Countryman Isomax Headset Microphone is the original Countryman head-worn microphone and a favorite for both speech and performances. The Isomax features an omnidirectional polar pattern with a flexible boom for easy positioning and the sensitive capsule features a full 20 Hz to 20 kHz frequency response for full, clear audio reproduction.

The Isomax effectively rejects off-axis audio, minimizing feedback and residual noise. The flexible, adjustable band fits snugly and comfortably around the back of the head for concealed use on stage, during trade shows, speeches, sermons, etc.

A wide variety of colors and connections are available for use with various wireless transmitters. This version is black and features a screw-on TA4F connector for use with Beyerdynamic & Mipro wireless transmitters.

Q: 2. I have a Spider plate attached to my Nikon D750 (for Spider belt). Can I use this plate together with the Spider plate? If not, what's my better option, please?

Q: 6. Is this plate good for the RF 200-800mm?

A: The Canon RF 200-800 lens foot is about 5 inches long. The Really Right Stuff L85 Multiuse Fore-Aft Plate with 1/4"-20 Screw is 3.6 inches long so I would recommend a longer foot. I recommend this Wimberley P-35 Quick Release Lens Plate since it is 5 inches long. https://bhpho.to/2GjLcrb

Q: 8. Thank you everyone for your response. But I'm still wondering: if I mount this on a flat surface, and that surface extends out past the bottom of the clamp (not to the knob, of course), does the diameter of the shaft allow for clearance so the clamp sits firmly on the flat surface? Sometimes I use clamps on something other than ball heads. Thanks again.

A: Yes, the bottom surface of the Really Right Stuff B2-Pro-II 60mm will seat flat on the camera support plate system similar to BH #PLPMPMT1009. However, the knob can not be under the same plate surface because it's larger than the clamp high. The knob is 25mm while the plate is only 18mm. I will recommend the BH #REB2LRII with the Level since this part is the same high as the clamp and won't interfere if you place your plate on a flat surface.
