中古 プロマスター 1.7X（ニコンF）テレコンバーター

Put this on my D5600 and the autofocus is noticeably snappier than my old 2X teleconverter. The 100-day warranty gives peace of mind for a used lens, and the body cap was included as stated.

Caps are snug and the glass looks clean. Mounted it on my D750 and it grabs focus reliably in decent light, though it's a bit heavy for walk-around use. Feels solid for a used teleconverter, and so far the 100 day warranty gives some peace of mind.

Got this for my older Nikon gear and it’s built solid, with clean glass and smooth rings. Autofocus is a tad slower than I’d like on my D7100, but the image quality stays sharp with zero color fringing.
