A tele lens set featuring the BORG 54 (300mm f/5.6) objective lens. The adjustable M57 LIII helicoid focus unit makes the 54 lens viable for astrophotography. Compact and lightweight, the 500g body is comfortable to carry when travelling. Users can upgrade to a high-performance objective lens with the BORG 55FL or 72FL, which use apochromat fluorite glass elements from Canon Optron, Inc.
You can convert this tele lens to a telescope by attaching a BORG telescope prism and eyepiece (sold separately).
Attention: BORG camera mount adapters are NOT included in this set. Please purchase the relevant camera mount adapter and other necessary components separately.
