Zooming the lens a touch removes most of the toilet roll / distortion , far more than it does with the G7X or the 1" panasonics I`ve encountered - less distortion means less edge corruption - this is why the Sony Mk3/4/5/5a win at 24mm, there is no toilet rolling and less distortion than any of the canons but at the cost of a very soft and not so long end at infinity even at F4 . I prefer the canon option of the wide end having the compromise but a sharp much longer long end even at F2.8 and all distances even in the G7X series lens and the G5X-II optic is even better for this

Some Examples with descriptions for each

Zooming to 12.5mm (33mm) removes all the issues totally - only cropped to 16:9 to display widescreen the corners are just as good in the 3:2 version ....... no Corrections , Capture one - F4

The lens definitely performs better at 24mm F1.8 than the G7X optic and not that far off the Sony 24-75 in the MK3/2/5 as that lens likes to be stopped down also ..

Resized to 12Mp but you get the idea - F1.8 allows not too dark interiors to be shot at base ISO darker would make use of the superb OIS

Sonys have ISO80 as a pulled ISO which even Capture one recognises and corrects for nd gives APS_C like clean skies but limits highlight recovery , sadly canon don`t have extended low ISOs so you end up with ISO125 and noisy skies & shadows at base ISO (125 is no better on Sonys) .. of course you can do it manually with +2/3 of a stop and pull back to get the same ..

12Mp resize but again you get the idea, skies and shadows as clean as ISO64 on the big RX10 Mk3 due to overexposing and pulling back in RAW - I do wish the cam had ISO64 to do this automatically , it would help JPG shooters too

and lastly the croppability of the long end - 120mm F4 100% Crop in RAW in haze but you get the drift .. No complaints there and the lens is sharp edge to edge on the full image even at infinity where I found Sony and Panasonic failed

I never really had a gripe about "toilet roll" at 8.8mm (24mm) on the G5X II. Just make sure if you don't need f/1.8, stop down to f/3.5-4 to both grab DoF for landscapes you'd take at 24mm anyways, and pickup some resolution... Imatests on the link below showing relative apertures vs focal lengths vs resolution delivered on the G5X II...

Now granted, the inversion of fisheye optics at 24mm can create odd artifacts with bokeh. Again, if you don't need f/1.8, don't use it. Kills both birds with one stone.

When you need f/1.8, you need f/1.8 though...

This is stunning from a 1" sensor. And a smartphone cannot touch the colors and detail retained in these circumstances with a 10ft pole. Toilet roll issues aside, f/1.8 is f/1.8 in terms of light gathering capability. It's why you'd shoot a G5X II over say a RX100 VI. And it shows with indoor / low light shooting
