Sigma 35mm F1.4 Art DG HSM Lens for Canon, Black, 3.7 x 3.03 x 3.03 (340101)

First and foremost this is not a 3,000.00 dollar lens. I do not expect it to have the same exact performance as a high priced Nikkor lens etc. I fully understood the aperture limitations on the wide end. If I had wanted or needed a 2.8 wide range telephoto lens I would have hocked a kidney...sold some blood and one of my children for one. However I did not and so I accept what a lens at this price can and should do. Many people have reviewed this lens so to, yet again, give my two cents worth mostly would be much repetition. I will just hit some points. This lens has the potential to be nice and sharp. Seems many copies including mine have a slight front/rear focus error. I easily fixed this in the D750 AF adjustment...took -3 to nail the 400mm length nice and sharp. Long term fix and to insure spot on at various lengths and apertures I got the USB dock for the lens. It is not expensive and I got mine used...get one. The max potential seems to be with the dock if you need to fine tune the AF to the anal retentive level. The auto focus works fine on my D750. Works as expected...almost never hunts or missed focus and when it does it has mostly been do to the scene or using the incorrect AF metering for the shot. But this was rare. Again its not a 3 grand lens. The OS works fine...seems to add a few stops but then again at 400mm handheld there is limitations to any OS if you want tack sharp especially cropped. Put it on a tripod....simple. The lens is dark yes...but that is obvious...it is clearly stated the max aperture at 400m. If this won't work drop a kidney and a liver on the black market and get a 2.8 lens. Personally I value my kidney and liver and can't afford that so I learn to shoot with it. It does fairly well in moderate light....crank up ISO a bit and a tripod I have no issues. Handheld at f11 or smaller in anything other than sunlight well who's not performing? The lens or the person behind the camera..? The ability to set the C1 and C2 settings via the dock is nice. Helps in different situations to have a quick ability to change OS or AF priority etc. Overall its a fine lens at the price....not perfect but again at this price I do not have any complaints. if I had spent several grand and up then I could talk about a few but I spent under $800 so...keep it in perspective. Last there are always bad or defective copies....happens to all manufacturers even your favorite manufacturer...I have had bad copies of cameras etc from several top brands...it happens. Sometimes it may just not be your cup of tea....if so...drink coffee and be happy.

Prior to this, I purchased the 30mm Sigma EX (APS-C lens) and the 18-250mm Sigma DC OS. Like many, I had the litany of focusing issues that not even a -20 Micro focus adjustment on my Canon 7D could correct all the way (though it came close). I was a skeptic like most others when the NEW line came out, but after reading several reviews ( Digital Picture, DP Review - Gold Award, Amazon, Adorama, BHPhoto, Amazon) I said "Ok I'm in" To date my personal reference for prime glass is my trusty old Tamron 90mm Macro - the 172E. Yes. The 14 year old original, slow as molasses focusing 172E. If you're shooting close up portraits, who cares how fast it is. But the image quality and sharpness is sublime. HELLO Sigma 35mm ART! Sweet Lord does this thing deliver. And though I'm still playing a bit, I haven't felt like I've need to move my 7D Micro Focus adjust off one tick. However, the USB adapter was JUST released yesterday for these new Sigmas, so if adjustment is a must, voila! No need to send it off with your body. Center sharpness is tack on wide open at 1.4 and can yield amazing bokeh results in front and behind your target at close range. Stop it down to 2.8 or 4 and the entire field opens up. So far as lenses go, this SHOULD be your prime, no hesitation. Build quality is solid. Put a quality B&W MRC UV filter in front of this and you'll knock your own socks off. Gear: Canon 7D. Tamron SP 90mm Macro, Tokina 11-16mm ProDx, Tamron SP 70-300mm Di VC USD, Sigma 35mm ART. B&W MRC Filters UPDATE: 10/25/2013 I have since added a Canon 85mm f1.8 Prime and a Canon 70-200mm f2.8 IS Mk II to my line up. I am now firing this tele for closeup portraits and using the 35mm Sig for full body. It really makes for a gorgeous and highly versatile portrait duo. Although the Canon 85mm is still after 20 years a damn near unbeatable fast prime for next to nothing in terms of cost. I do use it with the 35mm sometime when I need to be less obnoxious than the air traffic controlling 70-200

Before I get into this, let me tell you that I'm just starting to do photography professionally and I've really only just begun purchasing higher end equipment. I'm using a Canon R6 with a Viltrox adapter. Since I'm just starting this business, I'm keeping my costs down by going with some non-Canon gear and so far, I'm really impressed with the quality of Sigma's lenses. My daughter is on her high school dance team so I wound up purchasing the Sigma 70-200mm 2.8 to get some on-field performances and just purchased this 24-70mm 2.8 for when her team hits the competition circuit indoors (high school gymnasiums). The Sigma pairs well with the Viltrox adapter and although the adapter has a slight gap to the camera, everything works perfectly. Images are crisp and the auto focus is very fast. I don't have a Canon lens to compare but I can't imagine it could be any better. This is a serious piece of glass that allow me to keep my shutter speed up and my ISO fairly low indoors under some crappy florescent lighting. I was able to keep my settings at f2.8, 1/800 second with an ISO of 2000. I've also started playing around with some long exposure photography with an ND filter. I'm very pleased with the results I'm getting. Most of my professional photography will be centered on portraits and sports so I'll likely be using my 70-200mm or my 100mm macro but when I'm indoors and close to my subjects, the 24-70mm is going to be a great option. It's definitely going to be a great vacation lens as well. If you're looking to save a couple bucks, you won't be disappointed with the Sigma. I'd love to have the RF Canon lens but with a cost of more than double the Sigma, I'll take that extra cash and get some other equipment or put it towards our next vacation and enjoy capturing some new scenery.

Un objetivo muy bueno. Un bokeh y comportamiento excelente

E' un obiettivo f 1,8 costante su tutte le focali. Nitidezza e robustezza sono tipiche degli obiettivi Art. Il mio obiettivo è per attacco sa (sigma) e copre perfettamente anche il formato per sigma SD Quattro H. Possedendo una fotocamera Sigma SD Quattro l'angolo di campo equivalente è pari a un 80-160 mm, che è ciò di cui avevo bisogno. A volergli trovare un difetto c'è il peso: 1490 grammi. Il peso è un fattore soggettivo a mio parere. Io porto il tutto in uno zaino quando vado a camminare anche per 15 km e non è un problema. Codesto obiettivo utilizzato su Sigma SD Quattro in modalità bianco/nero produce delle foto di una bellezza che è difficile descrivere.. Grandissimo obiettivo.

Je n'avais pas encore trouvé d'optiques de grandes marques (Canon & Nikon essentiellement) qui se rapprochent qualitativement de certains bijoux Leica-R que je possède ou que j'ai possédés. Je pense aux Apo Asph 90/2, 28/2.8 (II), 60/2.8, 180/2.8, Modular Apo 280/2.8 + Apo Leica-R extender x1.4 et même le 80-200/4 vs Canon Apo 70-200/4. Utiliser un adaptateur sur mes boîtiers Canon pour profiter de mes optiques Leica-R, c'était shooter à ouverture réelle, ce qui n'est pas d'un confort à toute épreuve, vous en conviendrez. Mais la qualité de ces optiques Leica-R reste toujours superlative et malgré cet inconvénient, j'ai préféré garder mon parc optique de la marque au logo rouge. Et puis Sigma a bousculé les marques bien établies en sortant cette optique (le 50mm ART semble être du même acabit) sans compromis, ou si peu, alliant haute résolution optique, haute tenue du microcontraste, maitrise des aberrations chromatiques, de la distorsion, du flare, du coma, du Bokeh. Seul le vignetage à l'ouverture maximale est marqué, mais pour une optique ouvrant à f:1/1.4, le reproche honnêtement n'est pas justifiable. Les optiques Leica-R ont été abandonnées au profit des numériques Leica-M et Leica-S. Le Leica-R numérique est mort, vive les optiques Sigma ART! Concernant la livraison, j'ai commandé à 17h00, j'ai reçu le colis le lendemain matin à 11h00: un service "super express"! Concernant l'optique en elle-même, j'ai dû l'étalonner via la station d'accueil USB (indispensable à mes yeux et plus précis que le correcteur interne aux boîtiers Canon) pour une mise au point ultra précise (ouverture oblige), avec une remise à niveau du logiciel interne. Rien à redire, c'est parfait. Concernant l'autofocus, moi qui suis un adepte de la mise au point manuelle, qui peut le plus peut le moins: très silencieux, et très efficace après mise à jour par la station d'accueil USB. Pour ne rien changer à mes habitudes, j'ai découplé le réglage de l'autofocus du déclencheur. La mise au point manuelle est très agréable avec le verre Eg-S de mon Canon EOS 5DMKII. Je n'ai pas assez de recul pour dire que cette optique me subjugue, mais les quelques essais effectués semblent déjà tenir leurs promesses. EDIT DU 27/07/2014: Après l'avoir essayée dans des situations de lumière difficile tout comme en plein jour, je confirme que cette optique est d'un très haut niveau et d'un excellent rapport Q/P voire le meilleur à l'heure actuel. La tendance chromatique est moins pointue que les meilleures optiques Leica-R mais très agréable tout de même, un peu chaude. Le vignetage est marqué à pleine ouverture mais s'estompe dès f:1/2.0. Pour le reste, c'est du très bon, la distorsion modérée est totalement corrigée par des logiciels comme DxO Optics Pro (télécharger le module adéquat) et Lightroom 5.5. L'autofocus calibré est parfait et la mise au point manuelle facile sur mon EOS 5DMKII. J'attends mon deuxième boîtier, l'EOS 6D. MAJ du 28/05/2018: Propriétaire de l'objectif depuis 3 ans. Qualité exceptionnelle avec une ouverture parfaitement utilisable comme tous les Sigma ART. Peu d'aberrations chromatiques même à pleine ouverture, bokeh superbe, diaphragme à 8 lamelles. Déformation quasi-inexistante. Parfaitement utilisable sur des capteurs (à plus) de 50Mp. Rapport Qualité/Prix sans équivalent. La mise au point peut être facilement réglée grâce à la technique DOT-TUNE. Le mieux est d'utiliser conjointement le dock USB qui affine le réglage de l'AutoFocus en fonction de l'appareil auquel il est couplé et de la distance de mise au point. Mise au point silencieuse, rapide et efficace une fois parfaitement réglée même à pleine ouverture. Le Hic c'est l'embonpoint et le poids, mais ça vous le savez sans doute, c'est la politique actuelle du "no undue hardship for top quality". Dernière version firmware à vérifier (2.0 à ce jour); sinon, la mise à jour se fait via le Dock USB... Un sans faute.

Bel objectif SIGMA, bon piqué, mise au point rapide, bon rapport qualité/prix, le Dock USB SIGMA s'avère nécessaire pour le calibrer correctement avant la première utilisation

Qualité exceptionnel. Un peu lourd mais piqué exceptionnel.
