Best 24mm Lens
The end of the year is coming. A great time to take stock. Over the past weeks, I have studied the test overviews for the different focal lengths at which we have tested. Actually, the fields of view ("what is in the picture"): if you use a 12 mm on an Olympus or Panasonic camera, then there is as much in the picture as when you use an 18-mm lens on a camera with an APS-C sensor, or a 24-mm standard lens on a camera with a full-frame sensor.
BEST WIDE-ANGLE LENs
I always look forward to making the list with the best wide-angle lens, because I have been using a 24mm lens for decades. I always have a 24 mm lens with a fixed focal length with me. That used to be an f/2.8, now an f/2, while the sharpness at f/2 of the modern lens is higher than that of the old f/2.8.
The Sigma 20 mm & 24 mm f/1.4 DG HSM Art were both surprising with image quality at high brightness. The 24 mm is slightly better than the 20 mm, but the field of view of the 20 mm is unique for this brightness. The Zeiss Batis 25mm f/2 is less bright, but it beats the 24mm lenses tested when it comes to image quality. The LCD with the depth of field on a Batis is super.
The odd duck is perhaps the Tokina Cinema AT-X 16-28mm T/3, because that is no ordinary lens: it is a dedicated video lens that you focus manually. More expensive and heavier than photography zoom lenses, but beautiful!

WITH OR WITHOUT LENS CORRECTIONS?
Lens manufacturers design lenses in which distortion, color separation and vignetting are not optimally corrected. They assume that lens errors will be automatically corrected in the camera (for jpg files) or afterwards in Lightroom or Photoshop (for RAW files). The advantage of this choice, for manufacturer and consumer, is that you can achieve high image quality at relatively low costs, because you do not have to use expensive types of glass to prevent all lens errors. But there are also, usually the more expensive, lenses where a manufacturer has gone to extremes to prevent lens errors in the lens design. CameraStuffReview shows tables and graphs of Imatest results with lens corrections ("in-camera jpg") and without lens corrections ("RAW" outside of Photoshop or Lightroom). You can thus use the scores that are closest to your workflow.
