About Cooke Soft Effect Attachment

Just imagine capturing high-resolution images with a stunning glow to the highlights, all thanks to the Cooke Soft Effects Attachment for 65mm & 75mm S4/i Prime Lenses. Unlike the effects produced by traditional filters, this lens attachment ensures your images are neither fuzzy, soft, nor screened. Instead, it delivers a subtle, yet noticeable effect that is most pronounced when the aperture is wide open, gradually becoming less pronounced as you stop down.

This lens attachment's design is inspired by Cooke's PS945 portrait lens, renowned for its exceptional performance in 4x5 large format photography. When paired with the 65mm S4/i Prime, the effect ranges from T2.0 to T4.0, while with the 75mm S4/i Prime, the effect extends from T2 to T5.6.

Designed for versatility, this lens attachment seamlessly fits both the 65mm S4/i and the 75mm S4/i lenses with the use of an adapter ring. Elevate your photography with the Cooke Soft Effects Attachment and experience the difference in your image quality.
