The picture angle of this lens on a digital camera with an APS-C sized sensor (most Canon and all Nikon DSLRs) is 45 degrees, which compares to the 44 degrees of the Nikon 35mm lens, but far short of the 53 degrees provided by the Nikon 28mm lens.
Its picture angle on a digital SLR is that of a normal lens, and makes a good replacement for a 50mm f1.4 lens. It is not by any means a wide angle lens, which is unfortunate considering the cost of the Nikon 28mm f1.4 lens, and the lack of a fast 24mm prime lens.

An easy way to check how this lens work in the field is to browse through the pBase camera database. I was disapointed on the lens I received, and only comforted by those pictures at pBase that I didn’t receive a particular lemon.
I am feeling my D70 have difficulty focusing with this lens sometimes, can’t really tell who’s fault though.
As to the warranty issue, FWIW a vendor I talked to also have the 1 year warranty, and he said the extended warranty was $10 more.

I received a bad copy from adorama.com today. I was really disappointed because I had great expectations from adorama.com..I’m sending it back today.

Photography is a serious hobby of mine, for more than 20 years. I own the lens for six months or so, and I am sorry to say – don’t like it.
Perhaps I received a defective lens, but I keep getting poorly focused photos out of my Nikon D70 with this lens.
I must say this was a big surprise for me, build and materials are high quality, it has a nice feeling all over, I owned another Sigma lens (which I really liked – see later) but these focus issues just made me leave the lens at home. I have a moderate collection of other Nikon compatible lenses, all but two are Nikon, the two others are Sigma lenses – this one and a 10-20mm DX zoom (which I love).
I also have a Nikon 35mm f/2 lens, which I had for three years or so before I purchased the Sigma 30mm f/1.4, I thought the somewhat wider angle, significantly wider apperture, and HSM AF would be great – they look great on paper, but… Nowdays my main two everyday lenses are the 10-20mm Sigma, and the 35mm f/2 Nikon.

Yes, this is a fast lens, and that’s terrific. But it’s clunky feeling, which may seem silly but has something to do with it’s awkward size and shape when shooting. It also didn’t come across as very sharp. I’m sure it passes some kind of resolution test for competence, but the pictures lacked “snap” and that’s a subjective response only. I like a lot of Sigma lenses but often discover that snappy look more in Nikon lenses–it might be sharpness, or it might be contrast (the MTF charts are still a mystery to me). But call this is heads-up warning to people thinking about the lens in any kind of professional or demanding hands. Sadly, there isn’t an affordable option. (This lens is optically the same for Nikon, Canon, and 4/3 mounts.)
