Get Canon 760D (T6s) + 18-135mm f/3.5-5.6 IS STM.

Use this combo for a few months, with the zoom lens set to various "prime lens" focal lengths such as 24mm, 35mm, 50mm, 80mm and 100mm, to explore your shooting preferences in different scenarios.

Later, you can supplement the kit zoom lens with the prime lenses of the focal lengths that you enjoy most often.

Slight correction as Kaso knows you can't get to 24mm equivalent with the 18-135 on the T6s.

I use 24mm equivalent a lot and that is why I bought the T6s body only and bought a used 15-85mm which will give 24mm equivalent focal length at the wide end.

Hi Dave,

I sense that you are a decent person and, in your comment above, you meant well. What I am about to write below is not to argue with you, but is to present a different perspective.

Whereas I was talking about "focal length," you were thinking of "field of view."

The focal length of, say, 24mm remains 24mm. Likewise, the designation 18-135mm always means the range of focal lengths from 18mm through 135mm; the designation 15-85mm means the range of focal lengths from 15mm through 85mm; the designation 24-105mm means the range of focal lengths from 24mm through 105mm... If one turns the ring of an 18-135mm zoom lens (or a 15-85mm zoom lens, or a 24-105mm zoom lens) to the 24mm marking, one is using the focal length of 24mm. Meanwhile, a copy of the Canon EF 24mm f/2.8 IS USM lens provides only one focal length: 24mm. In all cases, 24mm is 24mm, irrespective of what camera the lens is used on, e.g. T6s, 80D, 5D Mark III, or 5DSR.

Now, a lens set at 24mm is used on a crop-sensor body, the field of view 'C' is smaller than the field of view 'F' obtained when the lens is used on a full-frame body.

You may find that 'C' is too small for your application at hand, and you prefer 'F' instead. If so, you choose a lens that provides a shorter focal length (i.e. a wider lens).

Cheers.
