Yongnuo Yn 100Mm F2 For Nikon, Yn100Mm F2N

(!!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).

Yongnuo YN 100mm F2 for NikonMi spiace prodotto veramente scadente Flare continui sulla lente ed eerori di calcolo esposimetrico vistosi. Foto tutte con un alone bianco diffuso.Mi spiace ma prorio non ci siamo prodotto non consigilato.!!

Doy cuatro estrellas y digo por qué , no me a dado tiempo a probar a fondo en objetivo pero todas las pruebas que e echo las doy por muy buenas menos 1 la velocidad de enfoque hasta que la cámara te confirma que esta enfocado tarda bastante y tengo una Nikon d750 que precisamente lenta enfocando no es pero ese objetivo le falta ese toque , lo demás es muy preciso tiene muy buena nitidez , un desenfoque muy brutal , ley muy malos comentários de este objetivo cuando lo sacaron para canon pero la verdad que impresiona . Cuerpo metálico y de bastante peso , es una buena compra

Hab das Objektiv jetzt seit 4 Monaten. Bin begeistert. Es ist solide und gut. Es ist an einer d3300. Wenn man sich die Theorie anließt hat es Lichtstärke Blende 2 an einer dslr-Kamera, aber eine Tiefenschärfe von etwa Blende 2,8 bei apsc-Sensoren. Bei dem Durcheinander mit den Brennweiten hab ich es ausprobiert: Es ist der gleiche Ausschnitt gewählt, wenn ich an einem af-s dx 55-300 auf 100mm Brennweite einstelle!Die superleichte Randunschärfe bei Blende 2 ist bei DSLR kaum zu sehen. Bei Portraits kommt mir das sogar entgegen. Sonst nimmt man halt ne höhere Blende. Überlesen hatte ich, dass das Objektiv keinen Bildstabilisator hat. Bin ich aber sowieso kein Freund von. Ich würd's jeder Zeit wieder kaufen.Ob das Objektiv nun solide oder schwer ist, sei mal unbewertet.

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.
