Tominon 75mm f4.5 Enlarging Lens MINT (Pre-owned)

The Tominon 75mm f/4.5 enlarging lens is a specialized lens primarily used in the process of enlarging photographic prints from negatives. Here's some information about it:

1. Focal Length and Aperture: The lens has a fixed focal length of 75mm, which is suitable for enlarging medium-format and 35mm negatives. It typically features a maximum aperture of f/4.5, though some variations may exist.

2. Enlarging Process: Enlarging lenses are used in darkroom enlargers to project the image of a photographic negative onto photosensitive paper, thereby creating larger prints. The Tominon 75mm f/4.5 is designed specifically for this purpose.

3. Optical Design: Enlarging lenses like the Tominon are optimized for sharpness, contrast, and minimal distortion when used within the constraints of an enlarger. They are designed to project a flat, evenly illuminated image onto the printing paper.

4. Aperture Control: While some enlarging lenses have fixed apertures, others, like the Tominon 75mm f/4.5, may feature an adjustable aperture. This allows the photographer to control the amount of light reaching the paper during the exposure, thereby influencing factors such as contrast and depth of field.

5. Condition: When described as "MINT," it typically means the lens is in pristine condition, showing little to no signs of use or wear. This is desirable for collectors and photographers alike, as it ensures optimal performance and longevity.

6. Compatibility: The Tominon 75mm f/4.5 enlarging lens is designed to be mounted onto a compatible enlarger. It may use a specific lens mount or attachment mechanism depending on the brand and model of the enlarger.

7. Applications: Enlarging lenses are essential tools in traditional darkroom photography, allowing photographers to create larger prints from their negatives. They are commonly used by film photographers and enthusiasts who prefer the hands-on process of darkroom printing.
