The French version of Dpreview is Focus Numerique. And they just tested the new Leica 8-18mm lens. Here is the google translated text:

Impossible not to recommend this ultra wide-angle zoom that combines qualities in all points of view.
The weight is very contained, the grip is excellent, as are the adjusting rings. We would have liked a third to manually adjust the diaphragm. The quality of construction is perfect and the design, very successful.
Finally, on the optical quality side, it is very good. The lens delivers rich images in fine detail at all focal lengths, from the largest openings. In addition, the objective has a beautiful homogeneous behavior. It suffers however from a lack of homogeneity between the center, two thirds and the extreme edges of the images.

DPreview tested the new TG-5 and concluded:

The Olympus Tough TG-5 stands alone in its ability to stand up to the elements and get you photos in situations where no other camera could (or situations where you simply wouldn’t be willing to bring a dedicated camera at all).
And the TG-5 doesn’t feel like just a tool to use because you need it; it’s genuinely fun. It’s responsive, handles great, has a decent amount of controls and a reliable ‘auto’ mode for when you hand the camera off to your friends. It’s practical in that it also offers USB charging, so you can use any USB power bank to charge it up off the grid, and then you can Wi-Fi transfer images to your phone for easy sharing without lugging a laptop along.
