The Gehmann 505 iris works well in varying light. I can adjust the aperture quickly during morning and afternoon shoots. The 8/32 thread fits my sight securely and stays in place. Easy to use and reliable in field conditions.

Good for adjusting in low light. The adjustment is smooth and precise. A little harder to set initially, but once calibrated, it’s very stable. Works well with my existing sight setup.

I’ve used this with both daytime and twilight shooting. The iris helps reduce glare and improves target clarity. The threaded rod is solid and doesn’t loosen during use.
