YONGNUO YN100mm F2N 1:2 AF MF Large Aperture Auto Prime Focus Lens for Nikon DSLR Cameras

The media could not be loaded. (!!Updates Below)Lens build and weight seems fine but it has massive focus issues. On my D5100, it keeps on doing the focus seek even in lit environment. Most of the time it fails to focus at all. And when it does focus, the pictures come out blurry. I checked again with my Tamron 24-70 2.8 and nikon 35mm 1.8, my camera seems fine. I see some people made youtube video regarding this issue for the 50mm. Is this a firmware issue??I am going to check on another camera before sending it back.1st Update: returend the first one and got another of the same lens from amazon. Now, I tried it on my new Nikon D850, it still sucks, misfocuses over 50% of the time!! (Even after AF Tune). And no success focusing with live view at all !!! Also heavy vignetting (which is fine for me).Still waiting on Yongnuo to create a firmware update to fix these.Final Update: !!!!!!!!!!!I wrote to the CEO and the technical team to update the firmware. Although there was some back and forth in communication and they took their sweet time, they have delivered at last. The latest firmware greatly improves AF, even in live view mode. I am really happy with the lens now. considering its low price, i think it deserves a 5 star in price performance. as i said earlier, i don't care about vignetting (so did not test it either).

I got this lens a week ago, it’s a nice prime, however, focus is very slow and noisy, photos are soft when used wide open. I haven’t missed focus yet so I’m pretty excited about that. Although I could have gotten an 85mm f/1.8 for faster focus and sharper images, I wanted the extra focal length. And since I’m a portrait photographer speed isn’t all that important to me.All in all, it’s an “ok” lens. You get what you pay for. Would I recommend? Yes, for beginner photographers on a budget.

Product is very heavy but well put togethar. Seems to focus just fine and if i could hold it still long enough pretty sure the images will be sharp. So far when i can shoot without shaking images are great. Will be getting the 50mm soon

Nice affordable lens but you get what you pay for. Any amount of bright light in front of the camera (not even in the shot) causes terrible ghosting and loss of contrast. Auto focus is okay but loud. Lens is decently sharp, it’s too bad it can’t handle a little bit of light and it doesn’t help that it doesn’t come with a lens hood.

Don't focus, it's not possible do the manual focus

Awesome lense for the price. I was skeptical about it at first, but when I started taking pictures, I was really amazed at it's performance. No regrets whatsoever.

You CAN get some nice pictures but it takes a few shoots to get even one sharp. I have Yongnuo 35 and 50 mm ,and they are amazing for the price. But this one was useless for me.( I use Nikon D5600).I would say,don't go too cheap))that's probably what happened here.I will definitely have to invest some money in this focal length

Best bang for your buck!
