I'm going on a few vacations soon and am thinking about purchasing a new camera. Currently I just use my iPhone 6s. I've been searching the internet endlessly it seems and have came across these few cameras. Just wondering which would be the best for me? I'm looking for a high resolution image, easy to use and can transfer my images to my smartphone instantly. Nikon CoolPix B500 Canon Powershot SX730 Canon Powershot SX540
Thank you!
