Landscape photography, like any art form, is full of established ideas that are better known as myths. You’ll find plenty of people to argue their truth yet they hold little real substance in the photography world. What are some of the most common myths in photography today?
1. Full Frame is the Only Way to Go!
Full frame is one way to go but not the only way to go. One significant disadvantage of using full frame gear is the cost of it. Both full frame bodies and their respective lenses almost always cost more than the APS-C equivalents in a given brand. Part of it is due to technological constraints. The sensors are physically larger so it takes more to run them but some of it is also due to the hype and demand surrounding full frame cameras.
An APS-C camera is no less capable of taking good images. The main constraint for landscape photographers in the field of view. Full frame cameras have the advantage here, assuming you absolutely must capture as much of the scene as possible with no cropping. But how often is that truly the case? Often a crop will be needed here and there for better composition.
The size of the kit is another consideration. Full frame bodies and lenses mean more mass to haul around. At least it did until the introduction of the Sony Alpha 7 mirrorless series. Whether other manufacturers follow suit with lighter full-frame rigs remains to be seen, however. Is your backpacking trip specifically for photography or is that only part of the whole venture? If not then a smaller APS-C or Micro 4/3rds rig may be perfect for you.
