The Canon R100, paired with the EF-to-R adapter and lenses like the EF-S 18-55mm and the EF 75-300mm, offers an unbeatable entry point into travel photography for those on a budget. What makes this setup even more enticing is the sheer abundance of used EF and EF-S lenses available at incredibly bargain prices. I managed to pick up a used Canon R100, complete with the adapter and both lenses, for just $500—the entire combo in pristine condition.
