Overall, I was satisfied with this lens' action AF performance at this event. This focal length, on either a full frame or APS-C crop sensor format DSLR, provides a very pleasing portrait perspective even when used for tightly framed portraits at near minimum focus distances. But at this point, I don’t know if this lens just varies a bit, and we’re seeing the range of variation here Apparently they have found a problem with the lens in the MFT mount. Typical is for Sigma Art lenses to arrive in a nice, zippered, well-padded nylon case and this one gets the same. If you’re not, you can skip the ‘how and why I do this’ section.

New Sigma Art Lenses – including 14mm f/1.8 and 24-70mm f/2.8

They’re rugged, finely crafted tools that one feels proud to mount on their camera. Most folks may not notice this in casual situations, but I fear a demanding pro will notice a slightly higher percentage of misfocused shots. This is very much a lens designed to deal with the hardships and rigors working pros put their lenses through. However, these improvements are going to be hard to discern in real life images unless carefully captured comparisons are made. You need the focal length that is going to allow proper framing and proper perspective for your subjects.

Sigma 135mm f/1.8 DG HSM Art Lens Review

Don’t get me wrong, for both the price and the weight I am very impressed with the overall image quality. Find the point within each image that shows the least amount of change from sample to sample and you have likely found the center of the plane of sharp focus. The first set of comparisons is from the top-left corner and the second is from the bottom right.

Sigma 18-35mm f/1.8 Review -

While the fringing colors are present, they are quite mild for such a wide aperture lens. While the Canon performs well here, the difference is strong enough to be noticeable. Manual Focus Override Manual focus override works great, at least on the Nikon version I tried. Videographers will find similar uses for this lens. Those planning to use this lens only for portraiture may be thinking that linear distortion does not matter in a portrait lens. Though regarding build quality, my favorite feature of all comes with the ability to fix many focusing issues with the use of the Sigma USB Lens Dock. Uncoated filters are much easier to clean, but more prone to ghosting. Usually a lens can be made compatible by the manufacturer via a firmware update, but this cannot be guaranteed. I would also leave the hood in the box for resale time. Coma is generally recognized by sharp contrast towards the center of an image and long, soft contrast transition toward the image periphery. All in all, though, if you’ve got a hankering for wide and fast, it doesn’t get any wider and faster than this! Well done, Sigma, I look forward to seeing what you produce next. In case you haven't noticed, kids have this issue called "growth" and it happens unbelievably fast. But additionally, you get some minute little things that are impressive, at least from an engineering standpoint. Below is a similar set of comparisons with the exception being that these crops were taken from the absolute corner of the frame. While this attribute is not unusual, photographers intending to use focus stacking techniques, videographers pulling focus and anyone critically framing a scene should be aware. In this box sits the lens inside a plastic bag which sits with the hood inside the case. In lenses that have it, coma goes away as stopped down.

These combine to create a less sharp, hazy-appearing image quality at the widest apertures. A cloudy day meant that the sky was a huge softbox and I could use a variety of locations around the house without harsh light issues. They have discovered that it doesn’t sufficiently adjust distortion while shooting JPEG. The rear of this modestly-sized hood has a rubberized surface that makes it easy to grasp for bayonet installation/removal. In the real world, this lens is too darn heavy for what it is - and it looks long enough to be a telephoto, marking you as a pervert in public.

Sigma Officially Unveils 4 New Art Lenses | 2 Zoom Lenses.

All of the review-time-current Sigma Global Vision lenses have a really nice physical appearance with a feel that at least equals the look. If you are having problems or want to know more, you can learn more about the issue by clicking here And it feels like it can handle some roughing up too. The high quality look matches nicely with the high quality build of these lenses. However, I simply cannot call this lens’ size or weight a “design flaw” after I already docked a point for the image quality not being even more flawless. They go into and out of focus of course, but they do not grow or shrink while doing so. To make the effective focal length even longer, this full-frame lens is compatible with Sigma's latest teleconverters as well. TSC also has a considerably higher elasticity compared to Sigma's other products. Exceptional image quality, including impressive sharpness and negligible distortion, is right at the top of this lens' advantages. While both ft and m are provided, it is very difficult to see the feet markings due to the light-colored font used. Anti-Flare Super Multi-Layer Coating This lens' coatings reduce lens flare, internal reflections and light scattering that can occur between the surfaces of its glass elements. TSC combines the characteristics of metal and polycarbonate and has the thermal expansion/contraction properties of aluminum. Depth of field has much more to do with focal length than f/stop. An evergreen shrub in the yard proved most challenging overall. Sigma's Artistic A-Series Lens Sigma has organized all of its interchangeable lenses into three product lines: Contemporary, Art and Sports. Wide angle focal lengths make it more difficult to get a blurred background, but wide apertures make it easier. The quality of that blur, referred to as bokeh, appears quite nice with one anomaly worth pointing out. Optically this lens is extraordinary - but it's too big and heavy, has a silly zoom range, and I have little confidence that this lens will work with whatever camera I'm using ten years from now. The only downfall to this lens is what I alluded to in the opening paragraphs. The first was captured indoors while the second was from an outdoor image. And, the incredible image quality this lens delivers means that even the tiniest landscape details are tack sharp, including the extreme corners. While you're making wide shots, others are going to presume you're using a telephoto lens for inappropriate purposes. But in the big picture of all lenses, the second one isn’t obviously horrid even though it is obviously not as sharp. Cameras with the autofocus microadjustment feature also have the ability to adjust AF calibration for a lens in-camera. I tried mounting them – they do not physically fit into the back of this lens. Sigma has been introducing some very nice lenses in the Global Vision series, but I'm not a fan of the narrow categorizations. This durability will likely come with a hefty weight, but the final weight spec has not been shared. From this location comes this review's focal length range examples. Sometimes, honestly, this inclines me to just leave it alone which can ruin photos as you see here. My wife, using her unmistakable slightly panicked voice, called me to our finished basement to eradicate this little monster. By optimizing the power alignment of the lens, chromatic aberration has been corrected, achieving high image quality through the entire focusing range. It is not the fastest-focusing lens made, but it is far from the slowest. Axial CA remains at least somewhat persistent when stopping down with the color misalignment effect increasing with defocusing while the spherical aberration color halo shows little size change as the lens is defocused and stopping down one to two stops generally removes this aberration. That’s pretty standard, though, for almost every modern autofocus lens, so I can’t complain. At narrow apertures, this scene is busy with the viewer's eye being pulled all around the image. I released the spider outside as the carpet would have needed cleaning if I had squished it as requested. Five years ago, I was one of their harshest critics, but now I’m following their developments more than any other brand within the photography and videography market. This wide aperture is especially valuable after the sun sets, shooting under shade conditions as well as indoors using only ambient window light. And, when photographing portraits, the subject's face and/or eyes quite often fall into heavily shaded portions of the frame when using some wide aperture lenses. Basically, whenever people are present, this lens has uses. Simply put, you should seriously consider the specific focal length and aperture that you need because more practical alternatives abound. Nikons need no lens data to correct this; they can correct any random lens. One thing I should note, however, is the greater care needed in keeping the front element moisture and dust-free. The color rendition seems about the same as my Nikkor AF lenses. I should note that, when AF inconsistency was shown in the testing, there were generally two similar groups of results. As an aside, it is a shame that Nikon in particular, has tried to mess with Sigma lens AF performance so much over the years.

Canon EF 70-200mm f/2.8L IS II USM. Apply "photography" liberally within your family and the families of others so that we can contain the growth issue. It is very heavily damped, demanding two strong fingers to wrench it back and forth well. A focus distance window is provided with distance markings. If you thing you want one of these, you'll love it. It costs you nothing, and is this site's, and thus my family's, biggest source of support. In use on a tripod, this lens can cause even a good tripod head to sag slightly. perhaps the only missing feature is optical stabilization. Same thing, slightly out of focus in the other direction. Shooting with a narrower aperture of course remains an option. Then I set up the optical bench for the lens and on each copy run a distortion test and run the MTF at four different rotations, so we get a side-to-side, top-to-bottom, and two corner-to-corner tests for each lens. I mentioned that rain chases visitors away from state parks. A short telephoto lens can fill the frame with color from even mediocre sunsets. This anomaly will only be noticeable in similar shooting situations. What you get is what you get unless you want to much with it in Photoshop. If forced to pick a winner, I'd lean toward the Zeiss, but. Some examples of which you will find throughout this review. Let’s Start with How and Why I Do These Tests We start standards testing by getting ten brand new copies of the lens. Most of the distortion can be corrected by plugging these figures into. And, "growth" can only be stopped by this thing we call "photography". The Sigma is modestly more expensive than the Nikon and considerably more expensive than the Canon option. While this angle is similarly useful, the uses push toward tighter portraits, smaller products, more-compressed landscapes and away from more-general purpose uses. Manual focus is swell, just grab the ring at any time. I suppose this is pretty much your only close alternative, despite the slight loss of high ISO performance and the whole stop difference in aperture. Focus is silent, and you may grab the ring at any time for instant manual focus override. The landscape photography use I mentioned above is only the tip of the iceberg for this lens' complete usefulness list. Stars in the corner of a frame tend to bring out another lens aberration – coma. The footage scale is illegible; it's tiny and in dark gray. Leave them in the box for resale, and buy the real Nikon or Canon caps to use with this lens instead. You just need to be sure it's in focus and nothing moves. That is a positive attribute of a prime lens, especially with enough barrel space remaining available for grasping the lens behind the ring. At MFD, one shot AF was backfocusing a high percentage of the time. Our standard lab test results found in the image quality tool are ideal for evaluating contrast and resolution and for comparing various lenses and settings, but I also like to share some real world examples in reviews. If a lens accepts front filters, I can slap on a cheap UV filter and just wipe it down incessantly between every photo, when it’s raining very hard or if there are waves splashing, etc. The lens also has a push/pull zoom mechanism in addition to the traditional twist mechanism for enhanced usability. The autofocus is fast and incredibly accurate, the images are exceptionally sharp, and the bokeh is incredible. As this page is copyrighted and formally registered, it is unlawful to make copies, especially in the form of printouts for personal use. The blur quality in my real life applications has been nice. It is not the best-ever in this regard, but even with an only-moderately-fast AF system, it delivered a solid percentage of in-focus frames. Dash Cam, CiBest Car Dvr 2.7" LCD. Before we look in detail at each of the lenses, there are a few features which are common among all four. Performance: Okay, let’s get right to the point: Considering the limited scope of what this lens might be useful for, I wish it had slightly less coma, blooming, and vignetting. Even if portraits are not necessarily your thing, this lens may send you seeking portrait opportunities. If you bought this lens and tested it you might, or might not, think it wasn’t as sharp as it should be and if you were really, really careful in your testing might detect that bad corner. There are an infinite number of AF situations and it is impossible to exhaust all of the test scenarios. In the field, AF has been performing very well, but not perfectly. While I suppose that any image can be classified as art, my definition for art imagery is far narrower – and this lens has far broader usefulness than my definition's limitations. The Sony and Zeiss equivalents are priced considerably-higher than this Sigma lens. If you had both lenses to test side-by-side you’d prefer the first one for certain. Gilrajavy Liphobia Nicon Coolpix. Using a variety of test scenarios confirmed that some were easier for the camera and lens to perform well together on. The ring is large, but sufficient space remains on the fixed barrel to grasp the lens for use and for mounting/dismounting from the camera with a significant portion of that barrel space mold-ribbed to facilitate this task. As someone who uses a lot of ND filters, Circular Polarizers, and other technical filters, I love that Canon has a system in place. While this lens is designed to cover only an APS-C-sized camera sensor, this lens mounts and functions on a full frame DSLR. Of course, neither of these calibration options address calibration differences between focus points – only the camera manufacturer's service center is able to make this type of adjustment. It has been a great choice for capturing the daily memories of life. Compatibility with the Sigma Dock is risk reducing. Focusing is very quiet with only some clicks being heard as final focus adjustments are nailed down. In the image quality comparison, the Sigma handily bests the Nikon. This lens can create a significant amount of background blur and that highly advantageous feature is likely obvious by now. Nikon D5300 Black DSLR Camera with. I'm not ready to give up my full frame bodies, but. Sigma Global Vision and the USB Dock Sigma's Global Vision lenses get a classification of "A", "C" or "S", representing a primary Sigma-intended use of "Art", "Contemporary" and "Sports". A special treatment to reinforce it is applied to the surface, giving it greater strength and making it highly durable for long-term use. It's great people like you who allow me to keep adding to this site full-time.     DC: Won't work on full-frame; only works on APS-C format cameras. Of course, if Canon made your camera and there is a Canon "L" lens in the comparison mix, that lens is usually an excellent choice – practically a no-brainer. Infinity and long distance focusing are sacrificed and while extension tubes will not have as dramatic of an effect when mounted behind a telephoto lens as they do behind a wide angle lens, they can still make enough of a difference to matter, permitting a smaller subject to fill the frame. Focus on a very close subject and then on a more-distant subject, or vice versa, and "fast" will not be one of the descriptors you consider for defining the focus speed of this lens. Shallow depth of field can mean that the subject pops from a blurred background. This head shot was not close to this lens' minimum focus distance, but it illustrates nice feature compression and provides a peak at the background blur this lens is so good at
