Nikon AF-S Teleconverter TC-14E III

Nikon AF-S Teleconverter TC-14E III
Premium 1.4x Reach Extender for High-End AF-S NIKKOR Lenses
The Nikon AF-S Teleconverter TC-14E III is a high-performance 1.4x optical multiplier engineered to extend the effective focal length of compatible full-frame and crop-sensor Nikon F-mount AF-S lenses by 40%. It serves as an essential, space-saving tool for sports, wildlife, and aviation photographers who need extra telephoto compression without the burden of packing a larger, heavier primary lens barrel.

Designed with an advanced optical and mechanical layout, this teleconverter preserves the native resolving power, exposure metering accuracy, and Vibration Reduction (VR) stabilization capabilities of your pro-tier NIKKOR glass while introducing only a minimal single-stop loss in maximum aperture.

CONDITION NOTE (EXCELLENT GRADE / FRONT & REAR CAPS INCLUDED)
This professional-grade optical teleconverter is in Excellent, Fine-Grade Condition. It has been comprehensively bench-tested for alignment and electronic communication, passing data streams and driving autofocus systems with flawless precision.

Included Accessories: Ships complete with its native, matching front and rear bayonet protection caps.

Cosmetic & Mechanical State: The weather-sealed metal barrel displays virtually no signs of handling, mount scratches, or field wear. The internal optical glass layout is completely immaculate—pristine, scratch-free, and totally clear of any internal dust, haze, or blemishes.

1.4x Focal Multiplication & Pro-Tier Lens Integration
40% Extended Telephoto Compression: Transforms standard and super-telephoto lenses into longer-reaching configurations (e.g., converting a 300mm lens into a 420mm focal length, or a 70-200mm zoom into a 98-280mm equivalent tool).

Minimal 1-Stop Light Reduction: Multiplies your focal reach with a modest cost of only a single stop of maximum light transmission (e.g., an f/2.8 prime lens becomes an f/4 tracking system; an f/4 lens steps into an f/5.6 system).

Flawless Communication Passthrough: Preserves seamless electronic data tracking between the lens and camera body, ensuring full support for complex 3D color matrix exposure metering, accurate lens-shift VR image stabilization, and lightning-fast autofocus acquisition.

Weather-Resistant Shell & Protective Fluorine Coatings
Inclement Climate Sealing: Constructed with a rugged, heavy-duty structural barrel featuring advanced dust- and moisture-resistant weather seals around the physical mount junctions to mirror the durability of Nikon’s flagship professional setups.

Dual-Sided Protective Fluorine Barriers: The front and rear outermost optical glass elements are treated with an advanced protective fluorine coating. This surface tech actively repels water droplets, mud splatter, oils, dust, and fingerprint smudges, allowing for rapid, non-abrasive cleaning in blowing field conditions.

Universal Format NIKKOR Mount: Built with a precise, heavy-duty steel Nikon F-mount interface, accommodating both full-frame FX and crop-sensor DX format AF-S NIKKOR telephoto systems.

System Compatibility Notice
Teleconverters require high ambient light and fast maximum lens apertures to drive autofocus mechanics accurately. The TC-14E III is designed exclusively for select fixed-focal-length primes and fast telephoto zoom lenses within the AF-S NIKKOR lineup (typically f/2.8 and f/4 variations). For an exact, up-to-date breakdown of supported models, please cross-reference the official Nikon compatibility matrix.
