The Tempo 711K Tone and Probe Kitis a kit comprised of a Tempo 711K Tone and Probe Kit200GX Tone Probe Amplifier and a 77GX Tone Generator. The amplifier and tone-generator are intended to facilitate the tracing and troubleshooting a variety of electrical circuits in a variety of circumstances, including communication, alarm/security, automotive scenarios, and more. It accomplishes all of this without piercing insulation.

The probe, which can operate at levels of 30 dB, includes an LED for a visual indication of signal strength, and for recessed telephone test-set connectors. Also provided is a plastic probe tip to prevent accidental shorts.

The accompanying power-tone generator provides three selectable warble tones, a two-line modular test lead, and two-color LEDs which help you identify the polarity of a signal. It also includes a weather resistant case, and operates in conjunction with the tone probe via standard alligator clips.

Q: 1. Can you use this lens with Canon EOS R5 with the Ef to Rf adapter?

A: Yes.

Q: 2. Is it possible to swap the lens mount?

A: It is not possible to swap the lens mount.

Q: 3. Can the Waterproof Front Lens Barrel be submerged in salt water? If yes what are the cleaning recommendations after salt water exposure?

Q: 4. What’s the best set up for the Panasonic S1H? Should I get the Canon EF model and use an adapter?

A: Being that the lens is fully manual, you can use either the Canon EF, Nikon F or Pentax K model with the appropriate Leica L mount adapter.

Q: 5. I intend to use this lens on a Canon C100MK2 with a super 35mm sensor, but would like to take advantage of the full 24mm field of view for wide angles. What adaptor do I need to avoid to the crop factor? Is that possible?

A: The C100 Mark II has an EF mount and this is an EF mount lens. There is no EF to EF adapter. When you use this lens on the C100 Mark II it will be subject to the 1.5x crop factor.

Q: 6. I have a Canon Rebel T7I. which has a APS-C Size ccd. I asssume this will make the lens 38mm?

A: Yes, that is correct. As the Canon EOS Digital Rebel T7i DSLR camera has a 1.6x APS-C cropped sensor, when comparing your lens' equivalent angle of view to that of a lens used on a full-frame sensor camera, all lenses must have their focal length multiplied by 1.6x to find the full frame equivalent. As such, as the Venus Optics Laowa 24mm f/14 Probe Lens has a 24mm focal length, it would be the equivalent of a 38.4mm lens (as 24mm x 1.6 = 38mm).

Q: 7. Do I need a Slider to use the lens?

A: You don't necessarily need a macro slide but would greatly improve image quality and precise positioning.

Q: 8. Is this lens sharp enough for 50MP stills?

A: This lens is very, very affordable for what it does. Therefore compromises were taken. We would say the optical quality is fine for prosumers but not up to critical high end work.

Q: 9. is it compatible with a Canon EOS RP? I have the EF adaptor and it is not working...

A: While the Venus Optics Laowa 24mm f/14 Probe Lens for Canon EF may be used on the Canon Mount Adapter EF-EOS R, do note that the Venus Optics Laowa 24mm f/14 Probe Lens for Canon EF is a fully manual lens with no electronic contacts. As such, you would have to use the lens in full Manual [M] Mode or Aperture Value [Av] Mode (though you need to set the aperture using the aperture ring on the lens, not via the Control Dial on the camera body) and you must focus the lens manually. The lens will not autofocus and you cannot use the Auto or Scene modes when using the above lens on a Canon EOS R-series camera.

Q: 10. What is the hyper focal distance at F14 and F40? I use a Canon 90D.

A: The hyperfocal distance of the Venus Optics Laowa 24mm f/14 Probe Lens for Canon EF at f/14 would be 3.94 feet (1.2 meters). At f/40, the hyperfocal distance would be 17.17 inches (436mm).
