二手 Tamron 17-28mm F2.8 Di III RXD 鏡頭 – Sony E

Got this for landscape work and the constant f/2.8 is a lifesaver in low light. The focus ring turns smoothly but has just enough resistance, and it’s impressively compact for an ultra-wide zoom.

I’ve been using this for city night shots and the constant f/2.8 is a lifesaver—sharp corners even at 17mm, and it’s noticeably lighter than my old zoom. The autofocus is quick and silent, which I didn’t expect for a used lens.

Shot my first real estate walkthrough with it this morning and the constant f/2.8 kept everything bright even in dim hallways. The zoom ring is buttery smooth, and I honestly can't tell it's used—glass is flawless, autofocus is instant.
