I recently bought an 11″ MacBook Air so I could do tethered shooting on location. Unfortunately, Adobe Lightroom would not recognize my Canon 5D while tethered via a USB cable. After a little research and a phone call to Adobe, I verified that this is a bug exclusive to Lightroom on OS X Lion. I decided to try out Apple’s Aperture to see how well it would do with tethering my 5D. Well, it turns out that Aperture works great for tethering. As a result, I decided to give Aperture a good hard look. Adobe told me very specifically that they would not have a fix for Lightroom for at least several months. Since I’ve been able to use Aperture on my Macbook Air for several weeks now, I feel that I can compare the two programs and give you some insight into which one is better.
