Sigma 28mm f/1.8 overview

  • 1Description

This 28mm lens has a fast f/1.8 maximum aperture, with macro-focusing capability. It features minimum focusing, down to 7.9" with a reproduction ratio of 1:2.9). The 9-bladed aperture diaphragm obtains beautiful out of focus images. It incorporates the floating focus system and the use of two aspherical lens elements to minimize distortion, spherical aberration and astigmatism. The lens incorporates minimum vignetting optical construction in order to obtain adequate peripheral brightness with open aperture. Internal focus system of the lens eliminates front lens rotation, thus allowing the use of a perfect hood and easy use of polarizing filters. The lens also incorporates a dual-focus mechanism. It is easy to hold the lens, since focusing ring does not rotate during autofocus, yet provides adequate torque of the focusing ring during manual focusing. The lens materials used in this new lens are lead and arsenic free ecological glass.

    Sigma 28mm f/1.8 reviews

    W/A 28mm f/1.8 EX Aspherical DG DF Macro AF Lens is rated 4.3 out of 5 by 27.
    Rated 4 out of 5 by from You get what you pay for This is a cheap, wide prime with the bonus ability to function as a macro lens. While its 1:2.9 ratio as is not a 'true' 1:1 macro, it is already possible to almost get focus within the lens hood. It produces nice, sharp images, although you're wasting your time if you use the auto-focus for anything but inanimate objects. Pros: Cheap, wide and sharp Wide and well gripped focus ring Double positioned focus ring means that you can avoid accidentally bumping the focus Cons: Autofocus is the slowest on any lens I've ever used With this lens you get what you pay for. If you're expecting exceptional sharpness and 1:1 reproduction then this isn't the lens for you, but if you want a good, wide prime then you should definitely consider this.

    Rated 3 out of 5 by from I have a love/hate relationship with this lens. This lens has infuriatingly loud and slow auto-focus (no HSM), a dumb manual-focus design, and it often produces unacceptably soft images when used wide open at f/1.8....BUT...Stop it down to f/2.2 or further and be patient with the focusing and it can produce some stunning results. Colour and contrast in particular are drop-dead gorgeous. It has a very nice bokeh too.It reminds me a lot of the old nifty fifty (Canon EF 50mm f/1.8 II) in that it's a cheap lens that is frustrating to use but when you do get a good shot it can turns out to be amazing. I'd even say the AF is slightly slower and noisier than the nifty fifty (which is saying something).Unlike the nifty fifty however, the Sigma 28mm is rock-solid and well built. No plastic lens mounts or dodgy manual focus rings here. Everything is metal with nice smooth movements.The macro capabilities of the lens are useful, but not a true macro. It does focus down to about 3cm in front of the front element however which is handy. Unfortunately this very large focus range slows down the already noisy and slow AF - here is one lens that could really benefit from having a dual-range AF switch like those on Canon L-series lenses. Expertise: Semi-pro Problems Encountered: * Tediously slow and noisy AF.* Awkward MF switching mechanism (and no full-time MF).* Soft at f/1.8, but sharp by f/2.2. Items I Recommend: Patience

    Rated 5 out of 5 by from Great Lens After receiving the lens, this is now my go to lens as a walk around lens on a crop body. It is a fairly large lens, but it seems nicely balanced on my Rebel with a battery grip. The manual focus ring is a breeze to use once you get used to it. The macro capabilities of this lens are more of an added bonus to a great walk around lens as opposed to being a dedicated macro lens. The only thing that is a downside to this lens is the auto focus. It is slow and noisier than the canon variants. It is fine however in most environments. Nice fast wide prime for the price!

    Rated 4 out of 5 by from Excellent Lens! I bought this along with a Canon 50mm f/1.8 and Canon 70-300 f/4-5.6 IS USM with the Canon 60D body. I'm getting back into photography after being a 35mm film buff over 20 years ago. From my previous experience, I believed that prime lenses are better than zooms for image quality and fastest aperture. I bought the Sigma because it was the best value for 28mm f/1.8 out there for Canon. I use it as my main lens for capturing our first child (6 months old) and family snapshots mainly indoors. You don't need to use flash with the 1.8 but it does require you to mind the distances between subjects as the depth of field is quite shallow. I'm still learning the best way to autofocus (back in my day everything was manual focus) and had a few shots that were front-focused, but what I'm learning it was because I wasn't using spot focus mode. I find the images very sharp and they look great to me. The lens comes with a very sturdy, reversible tulip-style hood. It is a bit heavy and long for a 28mm but manageable for me. For the money, I would definitely buy this lens again and I'm not sure for someone like me it would make sense to spend over a $1,000 for a lens with similar capabilities. Highly recommended!

    Rated 5 out of 5 by from Great lens when used carefully This is one of my favorite lenses. I have used it for 5 years. People seem to be more interested in the 20 and 24mm versions. In terms of image quality this lens is MUCH better than the canon 28 f1.8 and more on par with the 35mm f1.4L. Colors are a little warm, but this is easily corrected and usually looks rather nice anyway. The combination of fast aperture, wide-angle and close focusing abilities allow this lens to take pictures which no other lens can. I have found that with very careful manual focusing this lens is sharp to the edge wide open! The biggest weakness of this lens is auto-focus. It is slow, not always accurate, and it requires two adjustments to switch between AF and MF. That being said, the AF is fine in brighter light when smaller apertures are used. Even in low light the AF can be used, as long as you are paying attention to confirm focus. Despite the counter-intuitive AF-MF switch, the MF with this lens is excellent. Almost as good as a classic MF design. If you can deal with this lenses functional quirks, you will be very pleased with the performance. This lens is good for up-close gritty documentary in tight dim spaces, surreal near-macro discoveries and even interior architectural documentation.

    Rated 5 out of 5 by from I am very happy with the lense. I bought this lense in Jan. 09 primarily for shooting Aurora's in Alaska. I just returned from a trip where I used it pretty extensively, and I am very pleased with the sharpness and overall color quality on all the shots. It is noticeably sharper than my 1.8 Canon 50mm. All shots were at f1.8 at 10 and 15 second exposure times and with manual focus. I also used it extensively for other low light conditions such as sunsets, etc, and was very pleased with sharpness. For kicks, I shot some wide open during the day as a test and as others have reported did notice softness and some distortation around the edges. But I'm not sure why anyone would shoot day shots at 1.8 anyway - at 2.0 and above it is fine. It is a solid feeling lense and I must have gotten a new lense with a different design for the manual focus setting because I did not have any issues with accurate manual focus settings or any difficulty using in manual focus mode. No focus drift, etc. On auto focus it was quick and precise - no focus issues at all. Overall I highly recommend this lense.

    Rated 5 out of 5 by from Wonderful for Video I primarily use my t2i for video and this lens tops all others. I had Canon's 50mm f/1.8 for a couple of months, but grew sick of shaky video because of the crop sensor on my camera creating the lens to be telephoto. But the f/1.8 on the that lens was just amazing. So I decided to buy this lens in hope of a better focal length with the same fstop. The first day i used this lens i realized it solved all my problems. For video, it gives fantastic, sharp DOF even in low light. The shakiness was taken way down too. As for photography, this lens is great as well. The colors are deep and rich, the fstop is great, and 28mm is perfect for most shots. Also being a macro, you can take some very cool still of insects or anything else very small. The lens comes with a custom lens hood and a nice protective case. A wonderful addition. The bad. Really there is only one thing. For some reason this lens goes just a hair past infinity. So when you rack focus all the way out, you get a blurry image. And adjusting it to exact infinity because of the play can get annoying. But this flaw still will not stop me giving this lens 5 stars. I recommend this lens for anyone serious bout DSLR filmmaking, especially if you have a crop sensor camera like the 7D, 60D, or t2i/550D.

    Rated 5 out of 5 by from Solid, Fast Lens I just used this lens while shooting a feature film on the 5D Mk III. It performed flawlessly, and it stood up to abuse as well. At one point it even got accidentally kicked across a parking lot. I thought that was the end of it, but it is a very robust piece of gear. Sharp even at f/1.8, and it's ridiculous how close you can have your subject in focus.
