UPDATE, 4/23/2019: My original review is below, however I wanted to change my initial assessment from four to five stars due to a couple of considerations. One, I have found battery life to be fairly consistently better than the 200 shots advertised, unless I spend a lot of time editing RAW files or similar processor-intensive activity. Second, and more important, Ricoh released their first firmware update on 4/22, a month after the US release date, and it includes two things: support for the updated Image Sync app, allowing the camera's Wi-Fi/Bluetooth connection to smartphones, and an improvement to the camera's low light focusing speed and accuracy. Thank goodness for that last addition! I'm impressed with Ricoh for getting something out so fast to address the biggest downfall with the camera, and it does indeed improve things. Focus speed in very low light is still a lot slower than my Panasonic GX85 (but keep in mind, I am testing that camera with lenses that have wider maximum apertures than the GR III) but it is much faster and hunts a lot less than it did pre-update. This improvement applies directly to the main reason that I didn't initially rate this camera at five stars, so I am happy to be able to address that with a positive improvement. I know there are still forthcoming firmware updates, since the camera still has a "Grain" setting on some JPEG modes that is not fully functioning, and that future update is actually mentioned in the camera literature. END OF UPDATE, ORIGINAL REVIEW BELOW.The Ricoh GR III has been long awaited by Ricoh users now, since the original APS-C GR was released in 2013 and used 2013 technology, and the GR II really only added connectivity to the same camera. Sensor, processor etc. have been from that era for six years now, so it was high time for an update. I was lucky enough to be one of the first batch of Amazon stock, so I’ve had some time to get to know the camera. Now, if you don’t know what the Ricoh GR series is about, watch some videos or read some of the reviews for earlier models; the recipe hasn’t changed. It’s a truly pocket-sized camera that, unlike other pocket cameras, has excellent ergonomics, is designed for quick and effective operation, even one-handed, and delivers unique and powerful images with high quality and fidelity.I’m coming from using the Ricoh GR II for almost a year, and the GR III came at the right time (close to my birthday) so I was able to sell my previous model with little wear and tear and try the new model. I’ve used APS-C and Micro Four Thirds in the past, with a Panasonic GX85 being my main camera at present, but the Ricoh GR series has always been a unique spin on a camera, and one that complements another system quite well. I loved the GR II but always worried about developing dust on the sensor (the first one I bought had dust from the factory, even, so I exchanged it), and the dust removal system of the new model was icing on the cake for me along with all of the other updated features.Rather than give a lengthy review which most people won’t read (I tend to like to ramble on), I’m going to give some bullet points on what I think this camera offers over the previous models, and similar cameras among the competition. Everything else you can get from a spec sheet or a review in a lengthier format.• Image quality is absolutely fantastic. I love it. High ISO looks great, the feel of images is just incredible. GRs are tuned to be... different, in a good way. This one preserves that, while dialing up the IQ at the same time. Now, if you really liked the effect filters from the GR II, they are here except for cross process (sadly... firmware update? Ricoh is very good about improving and developing on their cameras post-launch, and they listen to users better than most, which not going so far as to compromise what they see as the core concept of the GR cameras) but they have a slightly different feel. There are a lot more parameters to change, but the GR II felt expertly tuned from default. So, what about Fuji JPEG colors? Personally, I’ve always felt that Fuji’s colors were only special in an era when most manufacturers’ JPEGs were bad. Everyone has gotten better, but Fuji can’t iterate because they’ve already given their film simulations fancy names, and people know what to expect. I think Ricoh’s Positive Film style bests Fuji’s Classic Chrome, personally. And the contrasty B&W options Ricoh makes are a lot different than the more subtle ones Fuji makes, so it’s not much of a comparison.• The touchscreen is awesome, Ricoh really got it right. It feels almost like a Panasonic, sadly without a screen to access all the main functions via touch on the same screen, like Panasonic or Olympus. But surprisingly, touch to focus and shoot is a fantastic addition to the repertoire of a GR. I can even shoot with the camera in my left hand! Anyone who has ever juggled a drink and a camera should appreciate being able to compose and shoot with either hand! Unlike the cheaper Fuji XF10, there’s no lag or jankiness to the touch functions, they just work.• Image stabilization works super well! In such a tiny camera, shake is harder to eliminate, as I'm sure you've noticed with the GR II. This is a welcome addition. Some people said that wide angle lenses don’t need image stabilization, but some things come from experience, not spec sheets: it’s much harder to avoid shake on a small camera body that is very light, so anything to aid in getting stable photos is good. Plus, being able to handhold down to half a second or longer, with care, allows for very cool light trail and movement blur effects handheld which you just couldn’t do with previous GRs, or any of the small Fujis.• The added resolution makes 35mm crop a lot more viable. Macro function is improved, and very sharp. 50mm crop combined with macro can be quite surprising. On a camera which is limited to a single, wide angle focal length, resolution enough to allow for fairly heavy cropping is a great thing. On top of this, the lens is so sharp that crops don’t suffer from a noticeable drop in resolution. The previous GR lens was super sharp, this one is even sharper if you believe the specs and tests, and my experience backs these up.• There are a few flaws. No camera is perfect, and not every previous flaw in the GR’s design was thoroughly fixed. Battery life is sure not great, but you can eke a lot more than the rated 200 shots out of it by switching the camera off when you're not taking photos. AF is the big bugbear. Fortunately, it’s not as bad as they say. It's very similar to the GR II, except noticeably faster in good light, and possibly worse in very bad light. My GX85 eats it for lunch in very low light, but I hold that the AF only completely falls on its face in lighting you probably wouldn't think to get photos in. Low, indoor artificial light is the main culprit. Even in low twilight outside, I got focus to lock pretty consistently. It’s a significant disappointment even so, and the biggest reason I couldn’t give this camera five stars out of the gate, because the lackluster AF in the previous model has been talked about so much, Ricoh knew it would be a big deal to users in the new model. And they tried. The camera now has phase detect and contrast AF in hybrid form, which theoretically should cut way back on hunting and racking focus. In good light, it does. But in bad light, it still really needs work. Ricoh has pointed out that the design of the lens requires that a larger group of elements, instead of a single lens element, need to move around to focus the camera. This allows for the high image quality. But it shouldn’t make the camera hunt as much as it does in bad light.I do expect things to get somewhat better in firmware updates, and I may even add a star. Here's the thing: the GR III is definitely a worthy upgrade over the GR II, and rockets the GR back into a premium option. But the GR II is special in its own right, and you could miss the recipe that that camera was made of, including the grainy, dirty high ISO look and the long and slim body style. And the flash. I'm not sorry I replaced mine, though. Because the GR III is special.
