Welcome to Delta

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 the most wide-ranging resource for film-makers and photographers seeking and using enlarger, projector, macro, repro, process and cine lenses to create digital work. Spanning 130 years, Delta is a catalgoue of over 3,000 universally-adaptable lenses, including hundreds of unique reviews and articles.

The quick-browse catalogue below orders every lens by manufacturer and can be filtered by category or other keyword. 

The primary archive tracks generations of lenses with more in-depth information, and ranks hundreds for sharpness and rendition. Please use the main menu and search function to access further articles, pictures and videos.
