Examples in these results show a wide range of multipliers, including 1.4×, 2×, 2.2× and up to 8× magnification.

Some extenders are described as optimized for prime (fixed‑focal‑length) lenses of 135mm and longer, while others target specific zoom ranges such as 70–200mm and 100–400mm. Check the manufacturer's compatibility chart for exact fits.
