- Adjustable Iris Aperture Diaphragm Filter Pack M30 to M37 Iris Aperture Diaphragm Adapter Optical Diaphragm 1.5-26mm Lens Module Adapter Ring PVS-14 PVS 14 Optics

I recently installed this adjustable iris on my PVS-14, and I have to say, I’m seriously impressed with its performance. It works flawlessly, allowing me to quickly and easily adjust the amount of light coming through, which is crucial in varying conditions. The smooth adjustment mechanism feels solid and reliable, and it has a precision that rivals—and even outperforms—some of the more well-known models that cost five times as much. What really stands out to me is how well-built this iris is. Despite the lower price tag, it doesn’t compromise on quality. It locks securely in place and doesn’t feel flimsy or cheap in any way. I’ve used higher-end versions before, but this one really surprised me by how well it holds up. If you’re looking for a great, affordable upgrade for your PVS-14, this adjustable iris is an absolute steal! You won’t miss the expensive models at all.

Adjustable Iris Aperture Diaphragm Filter Pack (M30 to M37) – A Versatile Optical I recently picked up the Adjustable Iris Aperture Diaphragm Filter Pack (M30 to M37) for my camera setup, and I’m genuinely impressed with its versatility and performance. This 1.5-26mm lens module adapter ring is a fantastic addition to my gear, offering precise control over light intake and depth of field. Smooth and Adjustable Aperture – The diaphragm opens and closes effortlessly, allowing me to fine-tune exposure and sharpness on the fly. High-Quality Build – The materials feel solid and durable, ensuring long-term use without loosening or breaking.

Works similar to a manual gain where it can lower the light intake and dim the image. The smaller the aperture hole, the more crisp the image through the tubes. Allows for images near and far to be in focus simultaneously the smaller the aperture hole. Can clearly focus in on objects 100 meters away and my watch at the same time. Great product.

Stick out over the IR light pice ourther then that it good

Highly recommend. Great price for what you get.

This is the Best value great fit and finish and function (bar paying 200$ for a tarser )for a PVS 14 focus device !!! Even fits the dust cover over it. Not sure about durability but it does lock up and adjust silky smooth!!
