Buy the NiSi Reflex 250mm F5.6 MF – Telephoto in Your Pocket
A mirror lens folds the light path and packs a long focal length into a body barely bigger than a standard prime. For travel, hiking and anything where weight counts, that is a real argument. Then there is the look: points of light in the background turn into rings and give your shots a visual signature no conventional telephoto delivers. Focus is manual, which for calm subjects is the more precise approach anyway and hands you full control over the plane of focus. Buy this mirror lens today.
