Delete the ones I don’t like. I mean I take a thousand pictures on a two week vacation. I’m never going to look at 1000 pictures in the future.

It will be narrowed down to about 75, rest are deleted. They have no value to me.

If you don’t, you’ll have a few 100 thousand photos down the road just taking up storage and never looked at.

I view as a dishonest sale and pass on it.

24-70mm any day for more useful.

Sounds like you have it covered. Good luck and have fun!

Too dark for the 70-200 f2.8? No, just too heavy and bulky. The event is not going to wait for you so you need to change lenses quickly so I was thinking light and can fit in a jacket pocket. Unless you have some way to be comfortable working with it. Or were you going on a second camera?

My other thought with this lens are lots of people and you may be close to them most of the time so you likely won’t get the benefit of most of the focal range of this lens. So all the weight for little use. Confirm it when scooping out of site imagining folks all over the place.

Sigma should be good between 20-24mm, probably 24 will get the most use as you don’t want folks looking too small.

Keep it simple as you’re in a low light situation.

Go manual with auto ISO, setting what your high limit will be for ISO.

This is a parade so there is going to be constant movement. It’s at walking speed so try 1/125 shutter speed. Or try walking backwards with the subject and using a slower shutter speed.

Aperture between f2 to 5.6 depending on depth of field needed as well as available light. It’s night time so accept some noise in your images and fix latter. Idea is to get the shot. Better one with some noise vs missing the shot.

Narrow your lens choices down two lens for low light usage and use your feet to make them work. Carry both on you, maybe one in a jacket pocket so you can switch easily. Too many lens, too many choices to make and too many missed shots.

You didn’t say what the wide angle was but I’d test it at the parade time and the location to see how it looks. 24mm or 35mm will work for close up shots, just use your feet to frame how you want.

Other lens might be the 85mm for portrait type shots. Forget the 50mm. 24/35mm & 85mm should have you covered for the distances involved.

Try to have fun!

Build a sand castle on the beach. Hopefully covers what your partner wants.

Both peak over a dune and look at something in between you as a surprise and you could still touch as it wouldn’t be in the photo. Only you would both know.
