Knowing me I would take all of my camera gear and kitchen sink to a baseball game.
For those of you who have taken photos with your gear at a stadium what would be best for me to take as a spectator? I would normally not take my gear but the couple going with us just got engaged and I was thinking of doing some save the date shots for them at the stadium. My options are d800 with either 50mm 1.8g 24_70 2.8 or 85 1.8g and sb-800 or on camera flash if needed. Forecast is warm and possible rain. We can either take photos inside or outside of the cubs stadium. I want to pack smart especially since I'm taming the baby anyways. This is more of an improve gift idea. Weather they hire me proffesionally or not I want to give them this as a gift.
A wide angle lens will make the background appear smaller, i.e. you will get more of the background in the frame. This helps to get a bit more stadium atmosphere in the picture, even with close-up shots of the couple.
So maybe it is a good idea to sneak an additional 24mm lens into the diaper bag :-)
My walk-around lens for stadiums is actually the 24-70 for exactly the above reason and the versatility of being able to choose my framing with a zoom. I think for your case it is even more important, because with the baby you are not so flexible to move. But this would be clearly no option if you always have to carry the baby in one arm and shoot single handed. You might even consider to use a point-and-shoot. Then you actually can zoom and keep the baby save.
If you arrive there and find you have the wrong lens, you are stuffed and they will remember the date for the wrong reasons.
We will turn my bookbag/camera bag into the diaper bag and Ill use another smaller bag for the camera and lens.
My plan was to get there really early because parking is almost impossible and either you park close or have to walk several blocks and find parking in somebodys property or use public transportation from downtown Chicago which I really don't want to do.
I would use the 24-70 and take a monopod if you have one, use it as your "cane" when you walk in...they cannot deny you this as I understand it. Then, camera on monopod, self timer, hold it out in front of your friends and you get some nice shots. Overhead as well. You can play with the focal length but 24 is great on full frame.
