>>3762608I put both in my bag or 3 lenses max however some days I know that I intend to shoot only using one or the other and stick to it.
Typically, I'll use the lightweight 17-28 (previously always kept my 28-75) but the 17-28 is so damn light it was a no brainer.
If I want prime for shooting a bit of street or environmental portrait, I'll carry 1 40mm prime. For events I'll keep 17-28 and sling strap the 70-180 f2.8 zoom on one similar to this pic
