Sigma 340101 35mm F1.4 DG HSM Lens for Canon, Black & 878101 USB Dock Mount for Canon Lens-Black

After moving up to full frame from a Nikon D7000 to a Canon 5D MK iii I didn't have much cash left a few months ago for any expensive glass. My first lens with the Canon was their 50mm 1.4 prime. Some shots I loved but there was something that surprised and disappointed me with that lens. It didn't seem to render as beautifully as my old 50mm I had on my Nikon! Anyway, after then purchasing a Tamron 24-70 and being very pleased with it I decided to look around for something to replace my 50mm Canon prime.I came across a review of this Sigma lens and became very interested. After reading a great review on DPREVIEW and some other stella reviews I decided to take the plunge. Spending upwards of £700 on a prime lens is expensive but after just a few hours with this lens I am blown away.Before I get into the results there is something very different about this lens compared to what is out there at the moment. It is an absolute beauty to look at physically. Whilst this is of course not important at all it gave me a wonderful first impression when I opened the box, as did the nice case it comes with.Photos on my Canon with this lens are beautiful. They bokeh is smooth, very pleasant and very natural. However it is the sharpness across the range that blows me away with this lens. Straight out of the camera the results are astounding. If there is a case to be had for prime lenses then this is it. I really wondered if it was worth spending what is a lot of money for a lens just to have the limitation of one focal length but the sheer quality here is incredible. Apparently comparable lenses from Canon cost more money and results do not better the Sigma.There is one reason to buy this lens - if you've got a great camera you will only ever do it justice by buying expensive and brilliant glass. This lens is expensive but worth every penny. I love it!

Oh. My. Gawd.To say that this lens is sharp is an understatement. It will make every other lens that you own look soft - if it's not another Sigma Art series that is. It is everything you've read in the reviews and more.It is sharp across the frame even at f/1.4 but of course at that wide an aperture there is quite a lot of vignetting. This goes away nearly completely at f/2 and it's gone altogether at f/2.5. Aside from sharpness, the colour and contrast is just astounding. As a comparison, I have a Canon 16-35 f/4 IS which I bought for my other half which is no slouch as I'm sure you're aware. To be honest, I wasn't expecting this to be better than the Canon as the Canon is a great lens, but it is. Oh my goodness it is.At f/1.4 the Sigma is sharper at the edge / corner than the Canon is at f/4(!) and by f/4 it's in a totally different league both in terms of vignette, sharpness, detail and contrast. In fact I've only seen one other lens that's as good as this and that's the Sigma 24mm f/1.4 Art, which I bought before buying this one and is in fact the reason I bought this one.Bottom line, if you're looking for a 35mm lens to do landscape photography at f/8 or greater then get the Canon 16-35mm f/4 IS as that's a superb lens - far, far better than my 17-40, but... if you're looking for a 35mm lens that you can use at large apertures then there really is no competition. The Canon 35mm f/1.4 is not as good as this wide open. Not even close. At f/1.4 there is no other 35mm lens that I'd buy. Period.

It has taken me weeks to make a decision to buy this lens. I needed a wide angle but one that would work in low light. The Canon 17-40 is a great lens ( I borrowed it from a friend) but in low light it's not what i needed. I read and read about the sigma 35mm 1.4 and finally it arrived today. I snapped away and the results were fantastic. I didn't take my time, the sun was in and out and the captures were not that great but I could see the sheer quality in the photos. I had to check the lens because I thought it had IS, it doesn't but i was seriously pleased at the sharpness, colours and so on. I am out on a full shoot tomorrow and I can't wait.I am sorry for those who have had a bad experience with this lens, (not that many) I have read loads of revues on other lenses and all of them people have had bad copies. The Sigma 35mm has one of the best revues i have seen on a lens. I have the Canon 70-200 is f2, Sigma 85mm 1.4 and Canon 50mm 1.8 but i think the 35mm is going to be my favourite lens by far. I pushed the boat out for this and I know it was worth it. Should you buy it, don't be a snob and it is a big Yes! If this is what you need for the job. I can't recommend it high enough if you want or need a wide angle this is it. Good luck people.

I ordered this lens half expecting to have problems with auto focus and I did. It wasn't a case that it required fine tuning for my camera (Canon 7d) which I wouldn't have minded as I'm prepared to work hard for perfection. No it lacked consistency, it was out of focus most of the time and sometimes was worse than others. Was a non starter for me. I have been so impressed with the reviews I wasn't prepared to give up so I asked Amazon for a replacement and full marks to them, was at my door within two days, first class delivery which I didn't ask for. The second lens was completely different, consistent and AF was absolutely perfect. Well it was at 1-3 ft but slightly out at 6-infinity. (I'm being very very picky here wanting perfection) So I decided to purchase the USB docking station which allowed me to adjust that particular range. The software splits the lens into four ranges so you can adjust any one or all four if required. I tweaked the range I wanted by +10 and perfection achieved. I have a Canon 50mm and comparing the two on AF, the Sigma is now more accurate without doubt. I'm so so glad I persevered with this lens as it's become my work horse. The sharpness and colour rendition is absolutely beautiful. I won't go into all the construction and feel of the lens as this has been done enough by others but suffice it to say its my favourite lens. I've still given it 5* even though I had a problem, I'm just so over the moon with the quality of my photos.
