Gear purchase decisions can be complex, and can have significant financial impacts if we don’t take the time to think things through. Taking a longer term view, like 10 year purchase decisions, are actions that we seldom do as photographers. Like many folks I typically had a 3-5 year perspective when buying camera gear. I had fallen into the ‘incrementalism’ trap by thinking that if a sufficient number of incremental improvements in specifications occurred it would make upgrading equipment every 3 to 5 years logical and worthwhile.
