Soligor Pentax auto 110 teleconverter 1.7x

This Soligor 1.7x teleconverter was designed specifically for the Pentax Auto 110 system, offering a unique way to extend your reach while maintaining the ultra-compact charm of the world’s smallest SLR. Mounted between the camera and lens, it multiplies your lens’s focal length by 1.7x, allowing for tighter framing and enhanced telephoto compression—ideal for portraits or distant subjects.

This is one of the rarest accessories made for the Auto 110 system and a must-have for collectors or shooters looking to experiment with longer effective focal lengths without adding bulk.

Why You Want This Accessory:
This teleconverter is a rare, period-correct companion to the Auto 110 lens lineup, turning:
• The 70mm lens into a 119mm f/2.8 (~240mm full-frame equivalent!)
• The 50mm into an ~85mm, and
• The 24mm into a tighter standard lens, perfect for detail work

Despite the miniature scale, it adds real creative flexibility for a system often seen as limited by its compact design.
