Pre-Owned - Nikon AF-S 1.4x Teleconverter TC-14E III
The Nikon AF-S Teleconverter TC-14E III is a high-performance 1.4x F-mount teleconverter designed to extend the focal length of compatible AF-S and AF-I NIKKOR telephoto lenses by 40% with a one-stop loss of light.
Key Specifications & Features
• Magnification: 1.4x focal length extension (40% more reach)
• Exposure Loss: 1 stop of light (e.g., turns an f/2.8 lens into an f/4)
• Optical Construction: 7 elements in 4 groups
• Coatings: Fluorine coating on front and rear surfaces to repel water, dirt, and smudges
• Physical Build: Weather-resistant and dust-resistant durable lens barrel designed for professional field use
• Electronic Integration: Fully supports autofocus accuracy, exposure metering, EXIF data updating, and VR image stabilization
Performance & Compatibility
• Best Use Cases: Optimized for sports, wildlife, and action photography when paired with fast telephoto prime or zoom lenses (such as f/2.8 or f/4 glass).
• Community & Expert Insights: Users on Backcountry Gallery Forums agree that while it provides valuable extra reach, pairing it with slower lenses (like an f/5.6) results in an f/8 maximum aperture, requiring higher ISO performance in low light. Meanwhile, discussions on platforms like Reddit r/Nikon show a consensus that optical benefits are most pronounced on high-resolution sensors and fast pro primes compared to simply cropping an image from a high-megapixel body.
• Mount Limitations: Built specifically for Nikon F-mount AF-S/AF-I lenses; it is not natively a mirrorless Z-mount native piece, though it can be mounted to F-to-Z adapters like the FTZ.
