I'm going on a 3-week trip to the US in September (Washington, Richmond, Chicago & Iowa) and this time I'd like to do some timelpases. Problem is I own one DSLR and you're stuck there not being able to get other shots while recording the timelapse. That's why I'm looking at a solution for a second camera.
1. A second DSLR. It would also be useful to have one with a wide angle lens and the second one with a more versatile lens. We wouldn't have to change lens every five minute during the day while visiting and walking down the streets. Problem is, my dream DSLR right now is a 6D. Rather heavy and expensive. I have other expenses at the moment to prepare this trip and I don't think I can spend €1500 on a camera right now. I could buy another one (second-hand, less expensive) that I could sell when coming home. But would someone buy a DSLR that had already two owners?
My biggest problem in having a second DSLR on this trip is weight. My backpack is heavy enough and a second camera means a second sturdy tripod for evening and night shots.
2. A GoPro. It's light, small, we could use it to make videos while driving and I could sell it when we're back from our vacation (or keep it...). Is the quality of the image still good if I zoom (Ken Burns effect, etc.)? How do I know the picture is good since there's no screen? How do you even frame it without a screen? They sell external monitor, would that be a solution?
3. An iPhone. The quality ain't that bad, we have an app that handles timelapses and we would have it with us anyway. Problem is space. If we use it for videos during the day, is there enough space on it at the end of the day for one or several timelapses?
What would you do? Any other pros and cons for each?
