USED - 100mm focal extender (M42)

The scratched label on the barrel is actually a nice touch—gives it character, and the optics are spotless as advertised. Tacked on an extra 100mm to my M42 lens and the sharpness held up way better than I expected for used glass.

I wasn't sure what to expect from a used extender, but the optics are genuinely spotless and the extra 100mm of reach makes a noticeable difference on my macro shots.

The label scratched into the barrel gives it a bit of character, but I was pleasantly surprised at how clean the glass actually looked. It slides onto my M42 lenses securely and gives a noticeable extension that works perfectly for close-up shots.
