[137 / 19 / 40]
Optical Limits just tested the new 28mm f2.8 pancake lens, and they claim it is one of the sharpest lenses ever made, with nearly 5000 LW/PH in the center and 4500 in the far edges. The highly acclaimed Sigma 40mm f1.4 Art only reaches 4500 in the center.
> The Canon RF 28mm f/2.8 STM is a pleasant surprise, especially in terms of sharpness. It may be a tiny lens, but optically it's a big boy and as sharp as a tack, even at f/2.8. We have seen only a few lenses with MTFs this high across the image field. Lateral CAs are low. Conversely, image distortions are on the high side in RAW files. However, we have seen much worse, and the issue is nicely auto-corrected anyway.
> Overall, the Canon RF 28mm f/2.8 STM isn't just adorable for its tiny size; it's also extremely capable - within its scope. If you want to keep a low profile during shooting, it's almost a must-have. Therefore - "highly recommended!".
