Original world's smallest DSLR at 18MP with touchscreen and IS STM, Canon compactness pioneer at budget pricing.
The Canon EOS 100D (Rebel SL1) with 18-55mm IS STM was the world's smallest and lightest DSLR when launched in 2013, featuring an 18-megapixel sensor with touchscreen in a body barely larger than some mirrorless cameras. The 100D proved DSLR miniaturisation could rival mirrorless compactness.
The 18MP sensor with DIGIC 5 delivers good image quality, and the touchscreen enables modern tap-to-focus operation. The IS STM zoom provides stabilised, quiet autofocus in a kit barely larger than mirrorless alternatives, and the Canon EF mount provides full system access.
Build quality is Canon's most compact DSLR with surprising quality for the tiny dimensions. The 100D broke the assumption that DSLRs must be large, delivering genuine Canon DSLR quality in what was then the smallest possible interchangeable lens SLR body.
The 100D with IS STM offers the original compact DSLR experience at affordable used pricing. The touchscreen, IS zoom, and Canon EF access provide genuine capability in a body that proves DSLRs can be genuinely small.
