Formula 5 135mm f/2.8 Multicoated m42 Prime Lens

The Formula 5 135mm f/2.8 is a lesser-known but well-regarded telephoto prime lens in the classic M42 screw mount, perfect for both film photographers and mirrorless digital shooters using an adapter. With its bright f/2.8 maximum aperture, this lens delivers smooth background blur and solid performance for portraits, nature photography, and compressed perspective shots.

Featuring multi-coated optics, it controls flare and contrast better than many of its uncoated vintage peers, giving you crisp images with rich color and depth. Whether you’re using this on an M42 film body or adapting it to your mirrorless setup, it’s a fantastic, affordable way to explore the joys of vintage telephoto photography.
Condition: Excellent
This lens is in excellent condition, with clean, clear glass—free from haze, fungus, or scratches. The focus ring turns smoothly, and the aperture blades are snappy and free of oil. Cosmetically, it shows minimal signs of use and has been well cared for.

Why You Want This Lens:
If you’re looking for a budget-friendly way to add some telephoto reach and beautiful bokeh to your kit, this is a fantastic choice. The M42 mount means it’s adaptable to just about any modern mirrorless system, and the multicoated optics help punch above its weight for sharpness and contrast.

It’s a great portrait length for film shooters and an even longer reach for APS-C digital shooters—turning into roughly a 200mm equivalent on crop sensors.

Perfect for:
• Portraits with dreamy background blur
• Experimenting with vintage glass on digital cameras
• Classic M42 film SLRs (Pentax Spotmatic, Praktica, etc.)
