Vivitar MC 70-150mm 2x 매치드 멀티플라이어

Paired this with my old prime lens and the 2x multiplier actually keeps the image sharp in the center, which surprised me. A little heavy on the front, but for the price used it’s a solid way to double your reach without buying a whole new telephoto.

I was surprised how solid this feels for a used lens accessory—the zoom ring is smooth and the glass looks clean. It adds a nice reach to my 70-150mm without losing too much light.

Picked this up for my vintage lens kit, and the matched multiplier slides on smoothly with a satisfying click. It maintains sharpness surprisingly well even at the 150mm end, which is rare for a 2x extender. Glad I found this used copy in such good shape.
