Primed to be refined: two new premium compact primes from SIGMA

The I Series is a small but quickly growing group of lenses from SIGMA designed specifically to offer high-performance, high-quality lenses for full-frame mirrorless cameras in as compact a package as is physically possible. I Series lenses share some common features:

  • Metal bodies, metal hoods, and high-precision metal insides
  • Pleasantly knurled manual aperture rings
  • MTF performance comparable to SIGMA f/1.4 Art lenses for DSLRs
  • Made in Japan

Available imminently at a Mike’s Camera near you or on our website, the 24mm f/2 DG DN and 90mm f/2.8 DG DN are the newest members of the I Series. Compatible with APS-C and full-frame sensors alike, they will be available for both L-mount and Sony E-mount.

13 elements in 11 groups, (including one FLD element, two SLD elements, and two aspherical elements) join forces inside a stylish metal housing to provide corner-to-corner image quality, even at the quite wide max aperture of f/2.

The 24mm f/2 promises “extremely high” lens resolution, and SIGMA notes that the optical designers paid special attention to suppressing sagittal coma flare, making it an ideal choice for astrophotography or night-time landscapes.

The wide aperture will help with any low-light situation, of course, and the moderately wide angle field of view is just as appropriate for dark interior scenes as it is for outdoor photography. The mount is dust- and splash-resistant, and a snazzy magnetic lens cap completes the package. Click here to order now.

Somehow the engineers at SIGMA have managed to offer the longest focal length yet to qualify for “I Series” status in an astoundingly tiny package. 2.52″ wide and only 2.35″ long—rhat’s even shorter than the 24mm f/2, which is 2.8″!—this lens is bound to be effortless and fun to carry around, unlike many much larger lenses to be found in the same focal length.

In order to achieve this, the lens is compatible with advanced in-camera aberration correction. That way, the lens optics themselves only have to correct problems that must be optically corrected.

Cleverly, it’s roughly the same size as the 24mm f/3.5 DG DN | C (not the new one announced above) and the 45mm f/2.8 DG DN | C, making them an easy complementary set. They even share a 55mm filter size, so you don’t have to pack triples when you’re getting the bag ready for a day of image hunting.

With a minimum focus distance of 19.685″ (providing 1:5 magnification), the 90mm f/2.8 is not a bad option for macro-style photography… which is actually very fun around this focal length, as it puts you far enough away to not disturb whatever you’re photographing (see the cool lizard in the sample images below). A respectable f/2.8 maximum aperture makes this a good choice for portraits, too.

The 90mm f/2.8 features the same sharp-looking design, dust- and splash-resistance, and convenient magnetic lens cap as the 24mm f/2. Click here to order now.
