Hi Tony

What seduced me into the Canon EOS M3 purchase, were the irresistible twin pillars of the low cost from B&H and that I would only use it infrequently, so familiarity with the Canon menu systems was a big factor. I've owned a Canon G11 & S110 (RAW) and their D30 (JPG only) and the EOS M3 really does blow these out of the water in terms of IQ which is not unexpected given the APS-C sized sensor.

The TG-5 looks like a excellent action camera and offers more advanced technology (4K video, etc.) than the Canon EOS M3 and looks to be indestructible too ; I would be tempted with this as a replacement for my aging Canon D30 for a "tough" camera although once again, I still hanker after that comforting familiarity with the Canon menus and inter-operability with my other Canon accessories. Sigh, it seems I am locked into the "Canon way"...

Cheers

Dennis
