Overall the corners and edges are still soft at 16mm, but overall the frame is acceptably sharp and usable.
For better corner/edge sharpness at 16mm, make sure to process the RAW file with any lens profile distortion correction turned off (unless required, of course). I`ve posted an example here[1].
Holy cow! This makes a huge difference. Thanks so much @boogisha!
Here's 100% crop comparison of the lower right corner. Left side is DNG converted with Iridient X-Transformer with lens corrections off. Right side is the same RAW file imported directly into Lightroom (corrections automatically applied).
This is a massive difference. I'm going to buy an Iridient license right away
Well worth the extra minute it takes to DNG convert my RAWs.
100% crops lower right corner of frame
Or use C1. I routinely turn off distortion correction. For many shots a little distortion is not noticeable. I frequently find it's also an improvement if there's a person near the edge of the frame and they don't get stretched.
Or RawTherapee.
Also, without distortion correction, the 16mm end becomes more like a 15mm

We're Noct messing around with this review.
Adobe Photoshop and Lightroom impress in a lot of ways, but their noise reduction lags the competition and their lens corrections lack a real-world basis. DxO PureRAW 3 aims to come to their rescue without totally reinventing your workflow!
The Sony ZV-E1 is the company's latest vlogging-focused camera: a full-frame mirrorless camera based the FX3/a7S III sensor, aimed at YouTubers and 'creators' looking to go pro.
The Sony ZV-E1 is a full frame camera targeting YouTubers. Chris and Jordan are Youtubers, what do they think?
Holy Stone produces dozens of low-cost drone models aimed at consumers. We look at the HS710 and HS175D to see if they stack up to other sub-250g offerings. Are these secretly great or more like toys?
Above $2500 cameras tend to become increasingly specialized, making it difficult to select a 'best' option. We case our eye over the options costing more than $2500 but less than $4000, to find the best all-rounder.
There are a lot of photo/video cameras that have found a role as B-cameras on professional film productions or even A-cameras for amateur and independent productions. We've combed through the options and selected our two favorite cameras in this class.
What’s the best camera for around $2000? These capable cameras should be solid and well-built, have both the speed and focus to capture fast action and offer professional-level image quality. In this buying guide we’ve rounded up all the current interchangeable lens cameras costing around $2000 and recommended the best.
Family moments are precious and sometimes you want to capture that time spent with loved ones or friends in better quality than your phone can manage. We've selected a group of cameras that are easy to keep with you, and that can adapt to take photos wherever and whenever something memorable happens.
What's the best camera for shooting sports and action? Fast continuous shooting, reliable autofocus and great battery life are just three of the most important factors. In this buying guide we've rounded-up several great cameras for shooting sports and action, and recommended the best.
