The Meike EFTZ-0.71X Speedbooster lens adapter allows Nikon Z-Mount camera owners to use Canon EF lenses with enhanced optical performance. This precision adapter reduces the effective focal length by approximately 30 percent and increases the maximum aperture by one stop, providing wider image angles and improved low-light performance. The construction from high-quality optical glass with multi-layer coating preserves image sharpness and contrast while minimizing stray light and chromatic aberration. The 0.71X focal length reduction factor makes it particularly suitable for portrait photography, as it enables shorter working distances and improved background separation. Nature photographers benefit from the extended reach without sacrificing quality, while videographers appreciate the enhanced control over depth of field for cinematic results. The adapter features precise electronic contacts that maintain full communication between the camera and lens, supporting autofocus, aperture control, and EXIF data transfer. The robust metal construction ensures durability and precise lens alignment while maintaining a compact design that preserves the portability of the camera system. Compatibility includes most Canon EF and EF-S lenses on Nikon Z-Mount cameras, with certain lens functions varying depending on the combination. The adapter measures approximately 45 mm in length and weighs 185 grams, maintaining a balanced profile when attached. This optical adapter opens up expanded creative possibilities for photographers by effectively transforming their existing lens collection into more versatile tools for various shooting situations.
