Whenever there is a major camera or imaging show happening, or when a number of new pieces of gear are introduced, I tend to get more emails from readers. The common question raised is “Should I upgrade my gear?” Assessing camera gear differences can be difficult. It seems to me that the vast majority of differences with which we concern ourselves are marginal at best. Truly meaningful differences are few and far between. Those differences are the ones that may justify us opening up our wallets… beyond just being affected by GAS (gear acquisition syndrome).
