Yongnuo YN85MM F1.8Z DF DSM Lens, Full Frame Auto Focus Medium Telephoto Prime Lens, for Nikon Z Mount Mirrorless Cameras

Awesome lenses with crisp quality pics

This arena is amazingly sharpValue for money

Objectif très performant de part sa luminosité. Très acceptable pour la vitesse de mise au point. Construction de qualité en métal et robuste. Qualité des images incroyablement précises pour le prix c'est un très bon achat.

This lens has autofocus ability, which appears to be unusual for a non-Nikon made Z mount lens. It fits my camera perfectly well and the autofocus is quick and smooth. I have had it for only a brief time but the images seem excellent. I have not used the programmable function button yet, but it could be handy. It appears to be a worthy substitute for the much more expensive (by a factor of 2 or more) Nikon version.

The YongNuo 85mm lens have poor flare issue and resolution.I compared the lens performance against a similar 90mm Elmarit F2.8 from Leica about 50 years old. The result was very disappointing. The YongNuo lens displayed flare even in the center of the picture (see attached photo zoomed 1000%). The flare reduced once the lens closes beyonf F2.8. The camer used for testing was Nikon Z7 with tripod mounted lens shot is aperature mode. The included two pictures first with YongNuo at 1.8 and second with F2.8 (widest) Elmarit Leica lens from 50+ years ago. In testing the Elmarit lens is better performer than the new YongNuo lens. I used manual focus on both lens as well as autofocus on the YongNuo lens. Its autofocus was relatively fast and accurate as long as enough photons are hitting the sensors. There is significant flare even at the cnter of the pictures taken. The purple flare was noticeable all areas of pictures.Only saving grace of YongNuo is that its auto-focus was relatively fast and quiet. However, I was disappointed with the performance of thei NEW lens in comparison with the hal century old lens. I am going to save money for the Nikkor prime lens. This one is going back.

Most native Z lenses are big, expensive and, well, very big and very expensive.This lens was probably adapted from F to Z mount, but it reminds me of how light and compact standard lenses used to be.It's undenyable that Nikkon upped it on the lenses, but all the advantages of a lighter body go away with such huge lenses.That's where the Yungnuo comes in. Lovely build, light, great boké and very sharp!
