I have a 5D3 and the SL1 - so I have lenses suitable to each.
When I go light, I take the SL1 with two or three of the following lenses:
18-135 STM (almost always have this - not fast but very good for walk around purposes; for a number of reasons I prefer it over the more expensive solutions like the 17-55 or the 15-85). Have not tried Sigma or Tamron options on this camera.
10-18 STM - great when you need it
55-250 STM - ditto.
35 f/2 IS - which you have
50 f/1.4
My most used combination - which answers your questions - is the 18-135 STM and the 35 f/2 IS. Great little package.
