Tominon 135mm f4.5 Enlarging Lens MINT (Pre-owned)

The Tominon 135mm f/4.5 enlarging lens is a specialized lens designed for use in photographic enlargers. Here's some information about it:

1. Focal Length and Aperture: The lens has a fixed focal length of 135mm, which is suitable for enlarging medium to large format negatives. It typically features a maximum aperture of f/4.5, allowing for precise control over depth of field and exposure during the printing process.

2. Enlarging Process: Enlarging lenses like the Tominon 135mm f/4.5 are used in darkroom enlargers to project the image of a photographic negative onto light-sensitive printing paper, thereby creating larger prints. These lenses are specifically designed to produce sharp and evenly illuminated images on the printing paper.

3. Optical Design: Enlarging lenses are optimized for image quality when used within the constraints of an enlarger. They are designed to provide minimal distortion, excellent sharpness, and high contrast across the entire image plane, ensuring that the resulting prints are of the highest quality.

4. Aperture Control: The lens typically features an adjustable aperture, allowing the user to control the amount of light reaching the printing paper during the exposure. This enables precise exposure adjustments and creative control over the final print.

5. Compatibility: The Tominon 135mm f/4.5 enlarging lens is designed to be compatible with enlargers that accept lenses with a specific mount or attachment mechanism. It's essential to ensure compatibility with your enlarger before purchasing or using the lens.

6. Applications: Enlarging lenses like the Tominon 135mm f/4.5 are commonly used by photographers and darkroom enthusiasts for producing high-quality prints from film negatives. They are essential tools in traditional darkroom printing processes and are valued for their precision, reliability, and optical performance.
