Used NIKKOR Z 24-70mm f/2.8 S, Type I. (Since there is no Nikon Z mount option in "Size," I have selected the Nikon F mount.) I have owned this lens for six years. I am a hobbyist photographer. I don't use this lens exclusively, as I have other lenses covering the same focal length, but it has been used for several years, so there is some dust inside the lens. Dust is visible on the front element, but not on the rear element, and I believe it has little impact on photos unless you stop down the aperture. The lens body has a solid, substantial build, so I think it's still in good condition, but the lens hood may show some wear. I have never touched the rear element of the lens since I bought it, and I have only used a blower to remove dust. I attached a HAKUBA XC-PRO protective filter to the front element immediately after purchase. As a bonus, I will include that protective filter and a Marumi C-PL filter. (The protective filter does not have a case.) I purchased the C-PL filter around July 2021, and since the effective lifespan of a C-PL filter is said to be about 7-8 years, it should be usable for a few more years. I took the lens and hood out of the box immediately after purchase and stored the box, so there are no missing accessories. The original box is also included, but the barcode section has been cut out. If you'd like to try a "holy trinity" lens, the Type I is available at a reasonable price, so please consider it. I have taken many great photos with this lens. *Added note: The protective filter does not have a case.
