Buying advice

When choosing a lens adapter, consider compatibility: ensure the mount types match your camera and lens. Manual adapters are cheaper but require manual focus and aperture control, while electronic adapters retain autofocus and lens data. For video work, look for adapters that allow aperture control without click stops. Build quality matters for heavy lenses. Speed boosters offer additional light gathering but are costly.
