Is the ricoh gr iii good for travel?
Yes, mostly. The Ricoh GR III has a 24.2-megapixel APS-C sensor and fits in a trouser pocket, which is exactly what you want when you're carrying a camera all day. Its fixed 18mm lens frames like about 27mm on full frame, a classic travel focal length for streets, food and most scenes.
The catch is that you get no zoom. If you want to pick out a distant building or a face across a market, you'll need to walk closer. My travel guide calls this the fixed-lens answer: superb pictures in a tiny body, if you can live without zoom. If you want range, the one-camera answer with a travel zoom will serve you better.
