The Countryman E6i Cardioid Microphone is a miniature ear-set microphone for virtually invisible operation in stage performances, trade shows, houses-of-worship, auctions, lectures and much more.

The cardioid version effectively minimizes off-axis feedback and noise from nearby monitor speakers, instruments and noisy sources. Flexible microphone positioning is maintained and the included windscreen minimizes the wind noise often associated with cardioid microphones.

The E6i is set apart from the original E6 with its softer flexible boom and silicon ear-pads. The flexible boom provides ease of boom adjustability to accommodate multi-user applications.

A wide variety of colors and connections are available for use with various wireless transmitters. This version is tan and features a 1/8" mini connector for use with Azden wireless transmitters.

A miniature cardioid capsule is mounted to a low-profile, flexible frame. This lightweight, unobtrusive design is available in various colors that virtually render the entire microphone invisible against the skin.

The included removable, quick-swap cable detaches from the actual headset, making it completely replaceable in the event of a short or break. The replaceable cable design makes upgrading wireless microphone systems easy, as they are available in a wide selection of connections to accommodate various wireless transmitters. The Duramax 2mm diameter cable provides extra strength, flexibility and durability.

The cardioid polar pattern is effective in minimizing off-axis residual noise from e nearby monitor speakers, instruments and loud sources. The result is increased signal-to-noise ratio and minimal feedback. The flexible boom provides a custom fit for multiple users and close microphone positioning. The E6i is also available in an omnidirectional version for maximum control over wind noise and plosives (popping).

This E6i's sensitivity response is optimized to accurately capture general speech without noise and distortion.

Related Questions and Answers

Q: 1. I have a Canon 18-135 zoom and want to use it to digitize 35mm slides. Will these work for that and get the image large enough to fill the frame?

A: Yes.

Q: 2. I have a Nikon D3200 and a Sigma DC 18-250 lens, 1:3.5-6.3. Are these extension tubes compatible with this set up and if they are, are there any issues at all that I should be concerned with?

A: These extension tubes will be fully compatible with the D3200 and Sigma 18-250 lens. The extension tubes will allow you to focus closer than the set minimum focus distance of the lens. There will be some light loss when using extension tubes. Adding about 40% of the lens focal length will result in the loss of 1 f/stop. Additionally, focus to infinity will be lost.

Q: 3. I want identical time code on four Pocket Cinema Camera 4K units. How many of these units do I need? Do I need anything else?

A: You will need four Tentacle Sync E mkII Timecode Generator with Bluetooth 5.0 (Single Set) acting as clocks for each Blackmagic Design Pocket Cinema Camera 4K. The 3.5mm Mini Jack Cable (Right-Angle) included with the timecode generator can connect to the 3.5mm ports on the cameras.

Q: 4. Can this be used for the Canon M50.

A: No, it cannot. The Vello Auto Extension Tube Set for Canon EOS is designed for use on Canon cameras that use the EF or EF-S lens mount. The Canon EOS M50 Mirrorless Digital Camera uses the smaller EF-M lens mount and will not directly accept EF or EF-S lenses or adapters. If you are looking for an option compatible for use with the Canon EOS M50, I would instead recommend the Movo Photo MT-CM47 3-Piece AF Chrome Macro Extension Tube Set for Canon EOS Mirrorless Cameras B&H # MOEXTCM47, if you need to retain autofocus, or the FotodioX Macro Extension Tube Set for Canon EOS M (EF-M) Cameras: for Extreme Close-Up Photography, B&H # FOMACROTUBEO, if you do not mind focusing manually.

Q: 5. Are these tubes compatible with a Canon 70D and a Sigma 105mm macro lens?

A: They should operate fine. The only electrical components inside are simple pass through contacts for passing lens information to the camera body.There are no optical components inside, just air.There are some compromises involved with macro tube use.When in use, focus to infinity is usually not possible.Working distance becomes very close.Depth of field/plane of focus becomes very thin.Magnification = Total Extension / Focal Length + Lens' native magnification.In the case of your Sigma 105 macro, native magnification is 1:1.With the full 68mm stack of Kenkos, you'll get 68/105=0.65x additional magnification, 1.65x total. The shorter the lens' focal length, the greater the additional magnification.For example, using the full 68mm set with a 40mm pancake lens, magnification increases from 0.18x to 1.88x.Downside remains depth of field. 68mm extension with a 40mm lens results in depth of field the requires either a subject (and its plane of focus) be parallel to the sensor and/or focus stacking multiple frames. So, not sure what you're hoping for adding these to a 105mm macro lens, there will be some additional magnification, nothing radically different as with a shorter focal length.Can't help with crop factor differences, no experience, no interest.

Q: 6. Hi i ve got a canon EOS 6OOD with 18 -55mm lens. Will the kenko tubes set work?

A: They work with my Canon 6D.

Q: 7. Hi, I own a GH4 with a panasonic 20mm 1.7, and a 45mm 1.7. Will it work with the kenko extension tube?

A: I used mine on an Olympus OMD-EM10, and they worked very well. They should work on your Panasonic, with a few caveats. Since the Olympus has sensor-shift image stabilization, I could not test to see if they have the connections for IS on Panasonic lenses. Also, you will have a very short working distance with those lenses. The 45 mm should work OK, but the 20 may be a little short. I mainly use mine with a 60 mm macro, but have used them on a 12-40mm zoom (mostly at 40mm) and also with the Panny 100-300 zoom. The longer the focal length of your lens, the better the working distance, which is especially important for insects. The Kenko tubes seemed well built, so I bought a set for my Nikon camera too.

Q: 8. Will these tubes work on D810 with Zeiss milvus macro or Zeiss 135mm f/2?

A: i do have an 810 but i never use with it i use with my d3s 700 and 7000 i know that it work with fix lens and zoom auto focus and most nikon camera it a good buy for me works great make sure you understanding how to use it .youtube.

Q: 9. will this work with the eos xsi efs 18-55 and the 75-250 lense ?

A: Kenko DGs should work fine with all EF and EF-S lens and camera combinations, same combinations as without the tubes. Note that magnification increase will be less with longer focal lengths.The math; extension tube length divided by lens focal length = magnification increase.This increase gets added to the lens' native magnification.Barely worth mounting up to your 75-250 especially when zoomed out, should be exceptional with your 18-55.Depth of field gets very very thin at close focus/high magnification, expect to stop down on a tripod and focus stack. Subjects in motion like bugs, flowers swaying in the breeze are tough subjects, done every day though, obviously not impossible.

Q: 10. Why does my 18-135mm Canon EFS lens not autofocus with these extension tubes?

A: The Vello Auto Extension Tube Set for Canon EF/EF-S Mounts and Lenses will have an extremely narrow area that can be focused--you might be slightly too close or slightly too far away; even a few millimeters difference can cause the focus to be lost. Always try to use a tripod for macro photography.
