In 2021 the Digital Enlarger Lens Test Archive outgrew its original home at 16-9.net – and its remit. It continues to expand, and is now one of the most wide-ranging resources for film-makers and photographers seeking and using enlarger, projector, macro, repro, process and cine lenses to create digital work.
Spanning almost 130 years, Delta contains 2500 such lenses that can be adapted to any camera via M42 helicoid adaptors. The archive identifies and tracks different generations of alt-lenses and employs a universal ranking system for tested lenses that compares sharpness and rendition styles.
