This large aperture 30mm F1.4 EX DC HSM lens is designed to match the APS-C size image sensors of digital SLR cameras. Two SLD glass elements are especially effective in the compensation of magnification chromatic aberration. Glass mold aspherical lens at rear group of lens reduces color aberration and provides high-quality image results. From 40cm (15.7) minimum focusing distance to infinity, this lens creates very sharp images with high contrast. The HSM models provide quiet high-speed auto-focus shooting, as well as full-time manual focus. Large Maximum Aperture of F1.4 can perform superbly in a great range of applications, including snapshots, portraiture, indoor shooting and landscape photography.

Sweet Lens
By Jim Hunt
This is a sweet little lens that really has no middle ground. You either love it or hate it. Most of the haters really either expect too much from this lens such as focusing in no light or on objects with no contrast and marginal light. The other reason there are detractors come from focus issues.This seems to be a user problem in my opinion. When you shoot at f 1.4, the area in focus can be pretty shallow. An example is at f1.4 and at a distance of 5 feet, the areas in focus is just .45 feet. If you have a DSLR with multiple focus points, you might find what you want in focus is not selected by the camera. This gives the impression of a focus issue with the lens which it is not.If you move into close focusing such as 2 feet using f1.4, the focus area becomes less than ¾ of an inch. Even the slightest movement by you or the subject can blow the focus. Again, this is not a lens problem but a user issue.However, don't be discouraged by the above comments. This lens has so many possibilities from creative images to group portraits to low light photography. You just need to put in a little effort to learn the lens (and your DSLR). Also remember that stopped down to f4 at 10' gives you 5.45 feet in focus.The 30mm lens also is about as close to a 50mm lens on a 35mm film SLR as there is. A 50mm lens was considered the de facto standard for an SLR in the old days and many people never had anything else. This is a very versatile lens.The lens itself has an excellent build quality and includes extras such as a lens hood and case. It is sharp and offers great contrast and compares well against such a well regarded lens as the Canon 35mm f1.4L which is about 3 times the price.You will not be disappointed in this lens at all and I highly recommend it. It is one of my favorite everyday lenses for my Canon 20D. (My everyday kit includs the Canon 17-40mm f4L, 70-200mm f4L, and a Canon 580ex flash.)

Useful addition to a lens collection
By luv my 20D!
I've had this lens for a couple of days and have shot in a variety of situations. The image is somewhat soft at f/1.4, but sharpens quickly as you stop it down -- f/1.8 looks much sharper and f/2 is excellent.From a purely practical standpoint, you can shoot in lower light w/o external lighting, and you can run higher shutter speeds in low light for better action-stopping when shooting people or animals. I was also amazed at the incredibly small depth of field I could attain -- for example, I was able to narrow the focus down to a single stem of a plant and have every other part of the plant far out of focus. Not something I've been able to do with my Canon 17-85mm and 10-22mm zooms.It's a heavy lens but it balances well on a 20D. Autofocus seems nearly as fast as with my Canon lenses. My one complaint is that the focusing mechanism (in auto or manual) isn't as smooth or quiet as with my Canons -- it sounds a bit rough in auto, and makes a slight "barking seal" sound as you go from close to distant focus manually.Nice of Sigma to include the lens hood and case, instead of charging exhorbitant amounts for the hood as Canon does.Overall, this is a very useful addition to my zooms, and it will definitely allow me to get usable natural-light photos in situations where I couldn't before.

By E. K. Arnold
This is one of the most controversial lenses ever, it seems. why all the fuss over this little guy? Simple, it cleverly exploits a hole in nikon's product lineup as a wide aperture (f/1.4) prime lens with HSM (hypersonic motor) at a price point just above nikon's older, slower 35/2 prime.Therefore nikon purists hate it with a passion, while 3rd party aficionados tend to have a more open mind.First off, if you're looking for something razor sharp at f/1.4 try zeiss or get over it. it's no fillet chef wide open, but that's not the point. the point is that you CAN use it at 1.4, which means it can shoot in light a 2.8 would be challenged by. also you can stop it down a few clicks and still be at 2.8, or shoot at f/2 or 2.2 and not be completely wide open.Second, while i'm sure there are sample variations out there, don't be put off by doomsayers on internet forums. opinions of actual users are one thing, but i dont know how people who have never used the lens can qualify it whatsoever.(but if you do order this lens, make sure its from a vendor with a good return policy. check for front focus issues when you get it; if you have a problem, sigma will recalibrate the lens. saves them money in the QC department, but at least they have good customer service.)for the record, i own three sigma lenses, all EX series, all bought online, and they all worked perfectly fine from day one.There are two categories of folks who will be looking at this lens: d40/d40x/d60 users and everybody else.for a d40/60 kinda person who wants to take no-flash, low light pics, there are no other options in this focal length and aperture class with an internal motor. period. you'd have to go to the micro-nikkor 60mm or 105VR to get an AF-S prime. sigma is coming out with a 50/1.4 HSM, but the 30's "normal" perspective is better suited for DX camera sensors with their 1.5 crop.nikon d80/200/300/700 owners can use any of nikon's (or sigma's) primes with full AF capability. unless you absolutely need f/1.4, the nikon 35/2 is cheaper and probably sharper. it doesn't have an internal motor, though, so for low-light action shots, the sigma is better suited for that application. but if you just need something inobtrusive for street shooting, candids, or a lower-profile lens, and arent worried about max aperture or AF speed, go for the 35/2.okay, how about some pros and cons:Pros:--not a small lens but lightweight.--low profile and normal perspective perfect for street/doc and candids.-- 1.4 maximum aperture makes this perfect for extreme low-light shooting.-- shallow dof at wide apertures results in creamy bokeh (out of focus elements)--HSM ensures fast AF; will work on D-series cameras without internal motors.-- takes 67mm filters.--sharp in the center at all apertures.--contrasty IQ--using fixed focal length lens forces you to focus on composition.-- EX build is better than sigma's bottom-barrel lenses, plus EX lenses have add'l 3-year warranty.--makes a good low-light solution for folks with slow variable-aperture kit lenses (i.e., 18-55, 18-70, 18-135, 18-200)Cons:--1.4 aperture gives extremely narrow depth of field. this makes this lens extremely tricky when shooting wide open, as shallow depth of field can be mistaken for focus issues.-- focal range is not as versatile as a zoom-- how much are you really gonna shoot at 1.4?--IQ not as impressive as cheaper nikkor 50/1.8--soft corners at almost all apertures (this matters less than you might think in low-light situations)--some known QC issues (which may be somewhat exaggerated)--more expensive than nikon 50/1.8, 50/1.4, and 35/2 primes.overall: recommended for d40/d60 users, low-light/available-light fanatics, street/doc shooters, people who will stay with DX for a while. not recommended for nikon nazis, or folks who may eventually migrate to FX.in practical use, this lens is probably more essential on an entry-level or mid level DSLR than a d300, d700, or D3. those cameras' improved high ISO performance means you can often stop down a 2.8 lens to f/4 in low light, lessening the need for a 1.4 aperture. on a d/40/50/60/80/200, however, you can keep the noise down in low light situations by shooting at wide apertures and not going above ISO 800.also, this is a DC lens, meaning that it is designed for DX sensors. FX-curious folks should probably get the nikkor 35/2 instead.while the 30/1.4 lens sees a lot of low-light use, its normal perspective and wide max aperture make it versatile in many conditions. i've stopped it down to f/8-f/11 and found it takes good landscape shots too. you never know when you might run into a situation where 1.4 is needed. it's a good one to have in the bag, just in case.
