Review Summary

In another life with another brand (Pentax), my favorite travel rig was a set of compact, high quality crop primes (15/20/40/70)-faster and much lighter around the neck than a zoom. Sony has put together with the 24/40/50 2.5G FF lenses with a similar philosophy. I bought this Sigma to add a compact tele to my compact G lenses for the A7RC. The 90 performs superbly and adds the Tele end I used to have with a 70 on APS-C but now with FF capability and terrific cropping potential of a 61mp sensor. The only catch is that the Sigma is made of metal, and it weighs twice as much and is twice the size of the compact Sonys. It makes it harder to put this kit in a compact waist pack or photo vest pocket, and too often, the Sigma gets left at the hotel. (It's also why the metal, massively heavy Sigma 135/1.8 never comes along on vacation.) Also, kudos for giving me an aperture ring, but why no hold button? Programmable controls on the lens are much appreciated with Sony's compact bodies. If this lens were more like the compact Sony G series and less like the old metal Zeiss FE lenses, I'd give it a perfect 5.

Pretty much perfect for what it is. The only thing I'd like to see different is having a lock to keep the aperture ring in 'A' or not, it can get bumped.

This lens is sharp starting wide open and going through the aperture range. I use it on a Sony A7R II. It also reproduces colors very accurately. Autofocus is quiet and quick. The build quality is exemplary, having an all-metal barrel and hood. It is also compact and lightweight.

This lens is truly outstanding. It's small and light weight. The image quality is very sharp all the way through the apretures. The color rendition is very accurate. The bokeh is very pleasing when shot wide open.

Really nice 90mm

In the era of mirrorless cameras, the balance between performance and size is even more crucial. There is a growing demand for "compact, high-performance, high-quality lenses" and SIGMA responds to this call with the "I" series of full-frame mirrorless exclusive lenses.
Available for L-Mount and Sony E mount, DG indicates full-frame sensor coverage, and DN indicates mirrorless-exclusive design.
The I Series represent a new option: Premium, Compact Primes that are stylish in appearance, with impressive specifications and optical performance.
Introducing the 90mm F2.8 DG DN | Contemporary lens. With its versatile mid-telephoto focal length, the lens is the longest I series lens yet, but still remains remarkably compact and light so is ideal for day-to-day use.
The lens also utilizes the camera's optical correction functionality, which is an advantage of mirrorless systems, SIGMA's optical designers were therefore able to concentrate on correcting aberrations that can only be corrected by the optical design, thereby improving rendering performance and reducing the size and weight of the lens.
With a minimum focusing distance of 50cm and a maximum magnification ratio of 1:5, close-up macro-style photography is possible. The lens highlights the subject, allowing photographers to focus in on fine details or create more abstract compositions.
The 90mm F2.8 DG DN | Contemporary shares the same 64mm maximum diameter and 55mm filter size as the 24mm F3.5 DG DN | Contemporary and the 45mm F2.8 DG DN | Contemporary, making them a natural trio, especially for filmmakers who use filters more regularly.
All I Series lenses feature an all-metal body, with high-precision metal internal parts, and a metal hood
All I Series lenses feature a manual aperture ring and knurled surfaces for an enjoyable tactile experience
An optional magnetic cap holder (CH-11) features a mini-carabiner for clipping to a camera bag, jacket or belt loop, and has a donut-style center hole to easily pop off a cap when it is time to place back on the lens
