SAMYANG10mm F2.8 ED AS NCS CS Ultra Wide Angle Lens Canon EF-S Type for Canon Digital SLR Cameras (SY10M-C), one size

Tres bien construit, cet objectif permet un contrôle ideal. Le focus manuel est très précis. L'anneau contrôlant l'ouverture fonctionne par clic, donc on peut facilement compter les changements.Pour faire du light painting longue exposition avec des sources lumineuses de diverses intensité, c'est un indispensable

Amazing images of landscapes, can't wait to use it for night sky imaging.

This is a great looking and feeling lens. Solid build construction, extremely smooth focus ring, and incredible sharpness out of it.Things to be aware of before buying it: it is MANUAL ONLY FOCUS, it is MANUAL ONLY APERTURE adjustment, and it DOES NOT have a chip in it (no metadata or help with focusing). Something crucial to understand about this lens is: what it lacks in ease-of-use features, this lens makes up for in sharpness and detail, IF USED PROPERLY.It seems to be the case that the money Samyang saved on this lens by not including: autofocus, image stabilization, a chip, or any sort of focus-assist element, they spent instead on giving the user the best quality optics in terms of sharpness, contrast, lack of color-casting, speed (f/2.8 lets a lot of light in), minimal distortion (for a 10mm non-fish-eye lens), and minimal vignetting.Overall, if you're looking for an ultra-wide angle lens with "L glass" quality optics and are willing to give up ease-of-use features to be under a $1,000 price point, this is the lens for you.My photo attached to this review (shot with a Canon T6i/750D), only had little touch-ups done in Lightroom to bring the shadows up and the highlights down a bit. No lens corrections were applied, although Lightroom CC did have a profile available for this lens, for when I will apply corrections to my shots later on.

Manual focus, no stabilization, I use for astrophotography, Nice lens
