Further to update, it does seem that the 18-135mm is the favoured suggestion at the moment and so that is the one I will give a look to first of all. I have looked at the lens preview thread for it and there are some nice images there which make me keen to try.
Thanks for the help everyone !
Heya,
Do you feel it needs to be a zoom? The 18-135 STM is a great lens and all. And inexpensive. But another alternative, would be a prime. Your camera has plenty of resolution to crop things and still have a very printable image. You could get a 28mm or 30mm or something like that, F1.8 or F1.4 even.
My "walk around" is a mirrorless APS-C with a 22mm F2 lens. Ultimately I found I didn't like walking around with a big camera and bigger lenses while just walking around, visiting, traveling, etc. But that's just my take, something to throw out there.
Very best,
