I’ve been using GRs for five years straight now. That 18mm perspective might as well be part of my body.
I actually shoot a good part of my pictures completely blind: Just point, and shoot. 18mm is wide enough to allow some imprecision in composition. With kids especially, this is a bit of a super power. I take pictures without breaking eye contact, or, in other contexts, without taking my eyes off the road.
When there’s enough time, the back screen works fine. To be honest, I’ve never been particularly bothered with not having a viewfinder. It’s not like a laptop, where I need to position a mouse cursor at a precise pixel position, or read tiny text. I don’t need the screen to judge details; those are visible in the scene itself, just a quick glance away. I just need the screen to judge my composition, and it’s perfectly adequate for that even in bright sunlight.
What I do miss, especially when shooting blind, is a more reliable autofocus. It’s a bit slow, and positioning can be a bit finicky (eye detection is not perfect). If the rumors of a GR IV in 2025 are true, this is the number-one feature I’d like to see. I’ll buy one on day one regardless, though. The current AF is fine, but it’s a bit slow, and better subject-detection and -tracking would really help.
There are so many little things about this camera that are so delightfully refined: like the cute little counter it shows whenever you switch it off, of the number of pictures you’ve taken today. Like the menu which explicitly controls which settings reset when switching the camera off and which don’t. Like the extremely useful crop modes for shooting 16 MP 23mm, and 8 MP 27mm. I use those constantly, even the 27mm one. Like the smartphone app that actually works well, and quickly. Like the macro mode that is accessible at the touch of a button. Like the control layout that actually works well for one-handed use. The way the camera switches on extremely quickly, such that I can typically pull it out and take a picture before people had time to react to the presence of a camera.
The GR III is about as close to a perfect camera as I’ve ever seen one. It aims to do one thing, being a pocketable snapshotter, and implements that with utter perfection (for the available technology). Perhaps that’s what you should expect from a continuous line of cameras spanning almost three decades (analog GR1 in ’96, small-sensor GR D in 05, modern GR in '13). But such refinement is unique in a piece of technology in my experience. And they kept improving it with meaningful firmware updates, too. Clearly a labor of love for what must be a tiny camera division at Ricoh.
