Sigma 5,0-6,3/150-600 DG OS N/AF HSM Contemporary Canon

Naturally this is a big and heavy lens, and with the tripod mount it works extremely well in all lighting conditions as you would expect. The image quality is excellent and I've attached a photo of a robin with some zoomed in insets to give you an idea. If you look carefully you can see the reflection of my house against the blue sky in the Robins Eye. It's that sharp. However, it doesn't stop there. That image was taken hand held at the full 600mm zoom. Yes, the light was good, and I'm using a Canon 6D at 1000 ISO, but to me at least that is pretty impressive. The autofocus was almost instant and spot on. Being a big telephoto, you are having to be at least 2-3 meters from the subject for focus! The other feature I like is the manual focus override. If you have the time, and birds are not very patient usually, you can fine tune the autofocus manually. The second sample was taken at night indoors and also handheld. This was at maximum ISO and the autofocus does hunt around a bit, but not bad for hand held indoors at 600mm. There is a feature to set the autofocus range to basically near or far and that reduces the hunt time in low light. You can see here that at max aperture the depth of field is insanely narrow, so when doing wild life stuff it's better to go up to F11 or so and have a higher ISO unless you have manged to squash your subject flat somehow. So the final picture was hand held at around 500mm with the lens resting on a railing to provide some extra stability. The bottom left inset shows the sharpness that can be delivered, the numbers on the blue container are perfectly readable. Again this was at 1000 ISO. I was a bit worried about getting this in my backpack, but the solid zoom cover is reversible and it all fits in very nicely after a bit of reorganisation. I've not bothered with the USB tuner. The results are amazing without it. But I can see how it might be useful. Finally, don't bother with a 1.4x converter. The images are better if you just crop! Sigma do seem to make very good lenses! My Sigma 12-24mm ultra-wide angle is also excellent!

Read the 5 star reviews. I can't add any more info to help you. It's heavy, it's quality and gives great close ups and vids. You can hand hold but I recommend a tri-pod.

I've just bought a "contemporary" version for my Nikon D810. I have only had it for a short while but am mightily impressed with both its image quality and the performance of the optical stabilisation (OS) system. Hand-held shots are completely viable, even at the full 600mm focal length. OS does its job well. Autofocus works well and fast, even in poor light, with very little "hunting". Build quality is good, zoom action is smooth. Image quality is excellent. I have bought a lens dock but in fact I don't think I'll need it as focus is spot-on out of the box. I bought this lens because I am frustrated with the performance of my Nikon 28-300 zoom at its long end, it never seems to be quite long enough and the image quality degrades a bit. Comparing images from the two lenses side by side is a revelation: not only do you get over twice as close but the image quality is also massively better. Downsides? It's heavy, but then it's a large lens with a reasonable maximum aperture so it can't be otherwise. I wouldn't want to lug it around all day though. Incidentally just for fun I tried it with my 1.4x teleconverter. Auto-focus mostly worked but it struggled a bit at longer focal lengths on poor contrast subjects. Maybe worth it for a static subject where you can set focus manually but not usable for anything which would require active focus tracking.

I'll start off by saying I'm a rank amateur photographer, just a hobbiest really, but felt I needed a telescopic lens purely for animal pictures. I opted for the Sigma lens because A) price wise it was perfect, B) I've already got a Sigma 70-300mm and it is a great lens. I use it with a Nikon 5600, no issues at all. It does have a bit of weight, you'll notice it immediately, but get used to it very quickly. The auto focus is quick and reliable, if you know you're camera, you'll be fine. Everything I've done with it so far has been free hand, it comes with a tripod handle (standard sized fitting) but I've not used it as of yet, it does make a good grip when carrying it around. The pictures I've added are of my first time out with it, picked a good day to practise with a touch of local knowledge and luck, and feel I've done not bad. Basically if I can manage it, anyone can. I've pushed the lens (and arguably my camera) to its absolute limit when taking pictures of deer at sundown, at full 600mm focal length, the pictures came out fine, but there came a point when the limit of f stop and ISO meant I didn't have time on my side, but this is a limit of any lens. The equivalent Nikon lens is around £300 more, so this one is perfect if the Nikon is out of budget. If I've one negative, it is the Sigma warranty. There is a 3 year warranty, but it isn't available for lenses bought via Amazon. When I've attempted to register it, I get an email stating it is not a genuine UK import so the warranty doesn't apply. So if you want the warranty, its an additional £41. I'm not sure if this is something Amazon is aware of and can assist with, but Sigma aren't budging on the matter. Anyway, brilliant lens, definitely worth it if you've any desire to photograph wildlife. At 300mm I was pretty restricted, even when cropping, at 600mm with cropping I'm not chasing an animal and only getting pics of its ass!

Llevo ya 10 meses con este lente y sigo pensando que es una de las mejores compras que he realizado. A un precio mucho menor que su contraparte de Nikon (200-500 f/5.6) es casi medio kilo más ligero, tiene 150mm más de longitud focal, más funciones, y una calidad óptica similar. Es compatible con Full Frame y APS-C (DX), tiene motor de enfoque integrado por lo que el autoenfoque es compatible con las cámaras más económicas de Nikon (series 3xxx y 5xxx), Optica: - Su nitidez es comparable con la del Nikon, ciertamente no es superior, pero aún así es excelente, sobretodo a cortas distancias (3-15m) y con diafragmas al rededor de f/8 y f/11 - El bokeh que produce es suave y muy agradable a la vista - Los 100 mm adicionales que tiene comparado con el Nikon son de gran ayuda, sobretodo en cámaras con sensor Full Frame donde 500mm aveces pueden sentirse un poco cortos - El recubrimiento de su elemento frontal es muy efectivo contra polvo y grasa, raramente se ensucia y se limpia muy fácilmente Funcionalidad - Este lente es pesado (casi 2kg) pero sigue siendo más ligero que el Nikon 200-500 por aprox. medio kilo lo cual en largas caminatas o excursiones se agradece. - El bloqueo del zoom en todas las posiciones marcadas es una gran función que tiene, puedes seleccionar tu longitud focal y bloquear ahí el zoom, evitando que se extienda cuando apuntas la cámara hacia abajo o se retraiga al estar apuntando hacia arriba. El Nikon solo ofrece el bloqueo en la longitud más corta. - Tiene 3 rangos de enfoque, Completo, 3-10m y 10m a infinito, otras marcas solo ofrecen full y 10m a infinito, y aunque no lo parezca poder bloquear en el rango corto es muy útil - Tiene 2 modos de estabilizador de imagen, para ambos ejes y solo movimientos verticales (para cuando se usa monopie, etc.) - Si tienes el dock de sigma puedes personalizar 2 funciones entre las que se incluyen la velocidad y precisión del autoenfoque y del estabilizador de imagen - Incluye una correa que puedes colocar en el pie del lente, yo recomiendo usarla para repartir el peso y evitar dañar la montura del lente o de la cámara Útil para: - Fotografías de fauna (aves, felinos, etc) - Deportes al aire libre (por su diafragma máximo de 5-6.3 es algo limitado para deportes en interiores o de noche) - Retratos - Fotografía de detalle - Fotografías de la luna Desventajas: - La apertura máxima es variable F/5 - F/6.3 por lo que la exposición puede cambiar al mover el zoom, se puede evitar esto utilizando siempre diafragmas de 6.3 o inferiores, yo recomiendo f/8 para una mayor nitidez - El zoom gira en el mismo sentido que los zooms de Canon, o sea en sentidos opuestos a los de Nikon y uno tarda en acostumbrarse - El pie del lente es algo pequeño y puede llegar a calar en la palma de la mano después de un rato

el teleobjetivo es de buena calidad, es robusto y las fotografías que se hacen con el, no tienen comparación, la unica pega que le pondré es que para llevarlo por el monte durante largo tiempo, se hace muy pesado y que el aro de goma que viene con el, yo no lo aconsejaría a nadie que lo use, ya que al hacerlo hay que presionar muy fuerte para poder ensamblarlo a la cámara y luego para quitarlo, sucede lo mismo, con lo que no creo que ese sea bueno para el cuerpo de la cámara que tiene que estar soportando la presión que se ejerce sobre el y creo que con su uso, podría dañar la cámara, pero por lo demás es que cuando ves los resultados en las fotografías, me siento muy satisfecho

Got this lens to get a lot closer than my 250mm mainly for photographing wild Koalas and seeing if they're showing signs of Chlamydia. Great lens and also much sharper and clearer than my old lens and obviously gets much nearer without disturbing them. Only problem is it weighs 5x more than my old lens but its worth it. Highly recommended.

The camera lens works great, the photos are clear and beautiful. The camera was packaged very well. The seller was wonderful.

Dopo alcuni mesi di utilizzo, soprattutto per foto ad avifauna, devo ritenermi soddisfatto. Il peso è sicuramente considerevole, nonostante ciò ho usato questo obiettivo principalmente a mano libera (tutte le foto allegate) con ottimi risultati. Di seguito i miei pro e contro di questo obiettivo. Non commenterò molto sulle prestazioni dell'AF in situazioni estreme, sia perché non sono un professionista, sia perché uso un corpo macchina non professionale, sia perché credo che per altissime prestazioni si debba pagare (purtroppo) molto di più. Sappiate che, per mia esperienza, in condizioni di luce e contrasto non ottimali l'autofocus può risentirne parecchio - ma in queste situazioni l'ultilissimo Manual Override mi ha comunque permesso di ottenere ottime foto. PRO: - Utilizzabile anche a mano libera grazie ad un'ottima riduzione vibrazioni. - Zoom lock, switch AF/MO/MF e switch per il range dello zoom comodi - Gamma di focali ampia, eccellente per fotografia di fauna - AF ben performante, regolabile e personalizzabile con l'apposito dock (purtroppo venduto a parte) - A lunghezze focali fino a 400 mm la qualità delle immagini è davvero eccellente - Funzione MO utilissima soprattutto a lunghezze focali più alte CONTRO: - Sopra i 400 mm ho riscontrato un lieve front/back focus (il mio corpo macchina attuale sicuramente non aiuta); inoltre, le immagini sono tendenzialmente morbide o mosse (ma considerando che molte foto le ho scattate a mano libera, vorrei ben credere) - Ovviamente a 600 mm le immagini tendono ad essere scure - La ghiera dello zoom non è molto morbida, inoltre per passare dalla minima lunghezza focale alla massima la si deve ruotare un bel po', perdendo un po' di tempo e talora lasciandosi sfuggire il soggetto. - Se non si imposta un range di AF, questo può essere un po' lento (possibile personalizzare l'AF con priorità al tempo di messa a fuoco col sopracitato dock) - Staffa per cavalletto molto scomoda da montare e forse un po' piccola Il voto reale che darei è 4,5/5 ed onestamente acquisterei di nuovo queste ottiche.
