Sigma 210101 18-35mm F1.8 DC HSM Lens for Canon - Black

Product Information

Lateral chromatic aberration is pretty low. The graphs indicate a little green/magenta fringing at wideangle, and moderately strong blue/yellow fringing in the middle of the range (note though that this tends to be visually less intrusive). At the long end, chromatic aberration is essentially nonexistent. With a minimum focusing distance of 28cm and a maximum magnification ratio of 1:4.3, this lens is excellent for close-up photography. When buying a Sigma lens the convention for a lens suitable for FF is "DG", which can be used for APS-C as well and the convention for a lens suitable for APS-C only is "DC" This applies, for as far as I know, only for Sigma lenses. So remember a "DC" lens you cannot use for a FF camera. A final footnote is that I hear far fewer complaints coming from Nikon and Sony users than I do from Canon shooters. My guess is that Sigma autofocus is probably at its worst on Canon bodies. All third party manufacturers have to reverse engineer autofocus algorithms, but my experience is (at least for Canon) that Tamron has this better figured out than Sigma. The Tamron 24-70mm F2.8 Di VC USD is probably the best value fast 'normal' zoom for full frame cameras, and like the Sigma 35mm F1.4, we had no hesitation in awarding it a Gold Award in our recent review. Not only does it offer built-in image stabilization, optically it comes as near as makes no difference to its Canon and Nikon counterparts, which are both much more expensive.

Sigma 18-35mm F1.8 DC HSM A Canon - DXOMARK

Note 05/18/2021 — an earlier version of this review incorrectly assumed f/1.8 on this lens was equal to f/1.8 full frame. This mistake has been corrected.) Variable focal lengths Distortion, lateral chromatic aberration, even vignetting which appears softly gradated, are all very well corrected for a lens like this. At 1.8TStops, transmission is excellent – this really is an f/1.8 lens and will likely appeal to filmmakers as much as still photographers. From a qualitative perspective, there is little difference in image quality between 5.1K and 8K when downsampled to 4K. To demonstrate, below is some “4K Crop” test footage using the Sigma 18-35mm f/1.8 on the EOS R5. Sample 4K Crop footage using the Sigma 18-35mm f/1.8 on the Canon EOS R5 As with the 35mm prime, this new model is one of the firm’s new Art series lenses challenging Canon’s L-series and the similar ED lenses from Nikon for optical quality.Despite its limitations when shooting stills, the Sigma 18-35mm f/1.8 is surprisingly great for video on the R5. Here’s why. Large f/1.8 aperture

Even though they don't guarantee it works with all models, it will be appreciated if they be interested in this case, and either fix the issue if they can, or publish that the product is not suitable with particual model. The lens is available for both Canon and Nikon cameras, but there are two different versions of this lens (one for each brand and mount) so it is important that you ask for and choose the right version when bying the lens. The R5 is effectively cropping the image for you. That’s more convenient than how the Canon 5D Mark IV functions, but the net result is still a low resolution image (18 megapixels instead of 45, the native resolution of the R5 sensor).Why does dpreview perpetuate the myth that an f1.8 lens used on APSC sensors has the same light gathering power as an f2.8 lens on full frame? At the same ISO (or ASA for film ) and lighting the shutter speed and aperture ( f1.8 in this case) will be identical for correct exposure on APSC, full frame, or any other format. This is basic science of optics.

That 1.8 means i can keep my ISO as low as possible and the DOF although shalow is acceptable (18mm@2m DOF=93cm and 35mm@2m DOF=23cm)We offer you to match any camera and lens to see if they are compatible or not. This is what the last users has tried to match. Nikon D3 + Sigma EX 12-24mm f/4,5-5,6 DG HSM Impressively bright constant f/1.8 maximum aperture is well-suited for working in low-light conditions and also provides greater control over the focus position when using shallow depth of field techniques. What makes a standard lens ideal for you? Certain important qualities are required, such as fast maximum aperture, versatility for snap shots, portraiture and indoor photography plus a good combination of a wide range of focal lengths in a compact design. SIGMA 18-35mm F1.8 DC HSM is the first zoom lens ever to achieve a maximum aperture of f1.8 throughout the zoom range. It is a wide aperture, standard zoom-lens for digital single lens reflex camera´s with APS-C size sensor´s. *1The lens has a focal range equivalent to 27mm - 52.5mm in a 35mm format and it can cover the angles of view of multiple fixed focal length lenses. This wide aperture, standard zoom lens enables the photographer to expand creative possibilities on any occasion.

Used Sigma 18-35mm f/1.8 DC HSM ART - Canon EF-S Fit - MPB

This is pretty hard to accept when I am accustomed to coming home from a wedding with 700-1000 shots taken with my own kit and typically won’t have to discard one shot for missed focus. Some report that their copy of the lens consistently focuses accurately, but others report similar frustrations with inconsistent focus results. Put simply, I think there is copy variation, and the fact that I reviewed a new retail copy some 2 years after the release date of the lens tells me that Sigma hasn’t been able to completely nail down this issue. A consequence of all of this is that in principle you'll get the very best results at large apertures by focusing and shooting in live view. This has its own pitfalls though - for example when focusing manually with Nikon's DX SLRs you have to remember to set the aperture to F1.8 before entering live view, as they're incapable of adjusting the lens's diaphragm during viewing. If you initiate live view at a smaller aperture, then you risk getting misfocused images. Meanwhile Canon users may have to set the aperture to F1.8 and press the depth of field preview button to force the lens wide open for accurate manual focusing, when shooting in bright light. Autofocus microadjustment As for sharpness. Hard to put in words. It's like you discovered what 24 mp can really do for the first time. Because you can open the lens to 1.8 you can literally have any dof and any bokeh you want. And low light: better than any dx prime and also flexible because of the zoom. At first blush it could be mistaken for a full- frame lens but it is in fact designed for APS-C format DSLRs and has the equivalent angle of view of a 29-56mm zoom on a Canon EOS 700D or similar body.Curious, the lens seems to perform much better on the Nikon D7100 than on the Canon 7D. I'm not comparing magnitudes--I know that those cross-platform comparisons are a no-no--, rather the performance is qualitatively difference. The Canon sample does get much sharper when stopped down, and is very even from edge-to-edge. By contrast, the D7100 sample gets (much) sharper at every FL when stopped down to f/4, and the center is much sharper than the edges, again at f/4.
