Yesterday we lined up the new Ricoh GR IV against its closest fixed-lens rivals. But let’s be real, people looking at the GR IV are not only weighing it against other compacts. A lot of our readers also consider small mirrorless setups as potential alternatives.
In this round, we are putting the GR IV, one of the most pocketable fixed-lens cameras out there, side by side with four mirrorless camera and lens combinations. Each one represents one of the most compact options in its brand lineup, all with focal lengths that land in the same ballpark as the Ricoh.
The Competition
- Ricoh GR IV / APS-C Sensor / 28mm ff equivalent lens
- Fujifilm X-M5 with the Fujifilm 18mm F2 R / APS-C Sensor / 27mm ff equivalent lens
- Sony A6100 with the Sony E 20mm F2.8 / APS-C Sensor / 30mm ff equivalent lens
- Nikon Z fc with the Nikon Z 24mm F1.7 / APS-C Sensor / 36mm ff equivalent lens
- OM System OM-5 II with the Panasonic 14mm F2.5 ASPH / MFT Sensor / 28mm ff equivalent lens
Here’s a side-by-side scaled comparison so you can really see how much smaller the GR IV is compared to those mirrorless body and lens combos.

Sure, the GR IV cannot match the versatility of an interchangeable lens camera since you are locked into its built-in 28mm F2.8 lens. But the size difference is hard to ignore. The GR IV is genuinely pocketable, which means you can take it anywhere without the hassle of carrying extra gear. What is unfortunate though is that at $1, the GR IV comes in quite a bit higher than the previous model’s $999 launch price. This is also more than what you would pay for the camera&lens combinations that we have compared above.
So what did I do? I still hit preorder on the GR IV within minutes of it going live. A few months back I sold my RX1R II, which delivered amazing image quality but was just too big to carry without a bag or hanging around my neck. I am hoping the GR IV will step in and fill that gap as my go-to daily fixed-lens camera.
