Honestly, wedding work is stressful enough without swapping primes constantly. The Sigma 28-70mm f/2.8 DG DN Contemporary is pretty much the king of value, but be careful with the focal range if you need that extra reach.

• Sigma is way lighter for long days
• Lumix 24-105mm has better stabilization but is slower I would suggest snagging a used Panasonic Lumix S 24-105mm f/4 Macro O.I.S. if you can find a deal. The extra end is a lifesaver.

Honestly, grab a used Panasonic Lumix S PRO 24-70mm f/2.8. The cheaper glass just wont hold up at weddings. Ive had nothing but soft focus issues with the budget lenses.

Saw this earlier but only getting to it now. Look, Ive been shooting events for a decade and honestly, the biggest mistake people make is obsessing over the aperture numbers without looking at the distortion profiles. When I first started out, I thought I needed that constant f/2.8 for everything, but in practice, the corner sharpness at wide open apertures on some of these third-party zooms is basically unusable for group shots. My advice? Before you commit, look into the focus breathing stats. If you do any video work during the ceremony, a lens that shifts its field of view while you pull focus is a nightmare to fix in post. I spent way too much time years ago trying to warp footage because my gear was breathing like crazy. You really want to check the specific optical correction profiles in your editing software too. Some of these smaller zooms rely way too much on heavy digital corrections which effectively throw away your resolution once you crop or adjust geometry. Dont just look at the price tag. Check the weight distribution too, because if it balances poorly on the S5ii body, your wrists are gonna hate you by the fourth hour. Just rent whatever you're leaning toward for a weekend before pulling the trigger, seriously. Itll save you a huge headache later.
