Used Nikon TC-301 2x Teleconverter

The caps fit snugly, and the glass is spotless—exactly as described. Paired with my 300mm f/4, the autofocus is still snappy and sharpens up nicely. The 100-day warranty gives me peace of mind buying used.

I’ve been using this teleconverter on my 300mm lens, and the glass is impressively clear—no noticeable loss in sharpness. The included rear cap and body cap were a nice bonus, and the 100-day warranty gives peace of mind for a used purchase.

The glass is crystal clear with no scratches or dust, and it mounted perfectly on my 70-200mm for a test shoot. It’s sharp enough that I can’t tell the shots from a native lens, and the included warranty gave me peace of mind on a used purchase.
