A used Sony FE lens is often the smartest way to get hold of good glass: optics hardly wear, so a used example performs just as sharply as new, for a considerably lower price. The used range of Sony FE is large, and because the system has been popular for years, there is something to be found for almost every purpose.
E or FE: what is the difference?
Both fit the same Sony E-mount. FE lenses are designed for full-frame cameras and also work on an APS-C body; pure E lenses (such as many Sigma DC DN models) are designed for APS-C and give a cropped image on full-frame. So always check which sensor your camera has before you choose.
What should you look out for when buying used?
With used lenses, look for scratch-free glass, smooth zoom and focus rings and a clean mount without play. With autofocus and stabilised lenses, it is good when everything works promptly and quietly. With us, every lens is professionally inspected, you get at least 12 months' warranty and you have 14-day returns, so you can take your time trying out whether the lens suits your camera and style.
Who is it for?
Whether you're just starting out with a lightweight standard zoom, an enthusiast wanting to go further with a telephoto zoom such as the Sony FE 200-600mm f/5.6-6.3 G OSS, or a pro looking for a GM telephoto lens such as the Sony FE 600mm f/4 GM OSS: this category has both affordable entry-level glass and top-class optics. Combine a standard zoom with a prime and you're ready for most situations.
