It is not correct, (but almost ) the G12 has a 28mm - 140mm equivalent lens

The closest you can get with an EF lens for fullFrame is the (discontinued) EF 28-135 IS lens, which is a very old design (was the second lens with IS in the Canon invertory, once).
the newr versions you might want to look at are EF 24-105 offerings which come in a fixed aperture F4L(version II) IS USM or a variable aperture F3.5-F5.6 IS STM version.

Re: G12 Lens

I don't have the G12 but the G16 ......

You may want to pick up an SD880 or a baby M camera with the lens - very compact and interchangeable lensĀ

Not really, I was looking at the specs of the G16 lens: 6.1 to 30.5mm. That is:

6.1 (W) - 30.5 (T) mm (35mm film equivalent: 28-140mm)

While the lens is equivalent to 28-140mm, optically it is still a very wide lens. Wide lenses are good when you need greater depth of field at lower f stops (i.e. f.18-2.0).

You will soon notice that your DSLR pics don't look that sharp due to limited depth of field because a 28-135mm DSLR at 28mm will have a depth of field about the same as your G12 zoomed all the way.

Another difference is the focusing distance:

DSLR 28-135mm lens: 0.5m / 1.6 ft

G16 6.1-30.5mm lens: Normal: 2.0 in. (5cm) - infinity (W), 1.3 ft. (40cm) - infinity (T)
