That 24-300mm must weigh a ton after walking about for a while. If I used that, I think I'd be shooting from a sitting position most of the time.
For what you intend to do, may I suggest another lens; the AIS 28mmf2.8 which is so well known I think I do not have to sing its praises. I'm sorry I have not used any 35mm lens, so I can't compare with it.
But for street scenes and walk about, with the 28mm f2.8 you do not need to focus much, even as a manual focus lens. If it is bright enough on the street, especially in broad daylight, with f11 the DOF is from <1.5 metres to infinity - you can practically shoot without having to re-focus - just point and shoot!
For shapes and objects - close-ups(?), it focuses to less than 8 inches.
I also think this lens would be good for what you use your other lenses for, landscapes and family.
It may cost a little more than the lenses suggested here, but I think you will not regret it. I just got one a week ago and I am most pleased with it. I am trying hard to contain myself from waxing lyrical about it, as it would be old hat to the more learned contributors to this thread.
Give the AIS 28mmf2.8 some serious consideration because once you get hold of a good one you will want to keep it.
