Question: I need a camera for real estate photos... wide angle lens & works well in low light... Will the Ricoh GR be a decent choice?  I'm clueless
Document: The metal body is light and feels solid. As with my full sized dSLRs, all the controls I need are easily accessible through "real buttons and knobs" on the camera body. This is as opposed to the typical arrangement for compact cameras where functions like ISO adjustment are buried somewhere in a menu tree.I've found the image quality to be top notch. The wide angle lens presents remarkably little distortion, the f2.8 lens provides a shallow depth of field when needed, and the sensor does a great job in low light allowing me to shoot comfortably to at least ISO 3200.
The 28mm fixed focal lens on this camera is excellent. It perhaps is not the fastest at f/2.8 but it delivers amazing results wide open and the large APS-C sensor of this camera can more than compensate for good low light performance.This combination will outperform just about any entry level DSLR in image quality, at a fraction of the weight and while also being pocketable. The image quality is noticeably greater than that of my D5100. Partly thanks to Ricoh/Pentax's decision not to include the AA filter in this package as well as the great lens pairing.Key to producing great images with a 28mm focal length is to get in close, if you do, you will be rewarded by great 3d looking captures.Ergonomically the camera is perfect, it's the first camera that I don't use a strap with, because of how well it fits my hand.
Just don't forget to turn off Macro mode; otherwise, when you snap down on the shutter, hoping for a quick shot, the lens will hunt forever. You'll be walking away trying to review your shot, wondering why the playback button won't work when you realized that the lens is STILL trying to focus.3) Good AF in good light. The AF is unreliable in low-light but that's expected for most compact, contrast-focusing cameras. In well-lit areas, AF is pretty fast - not as fast as the incredibly fast Olympus EP-5 or Fuji X100s, but definitely fast enough.So all in all, a decent camera.
It's not all chocolates and roses though. Despite being accurate, the focus is slow in low-light; the latter being a room with one or two lamps on. In the aforementioned shooting scenarios, the camera sometimes takes between 1.5-2 seconds before it locks. But once you're accustomed to the snap-focus feature and prejudging distances, it's not that big of a problem.If you're in the market for this camera, you know you're in it for the large-sensor photos. Heading over to Flickr and browsing the real-life samples will probably give you a better indicator of the IQ than what I can put into words.
While it does focus fairly quickly, there is still a noticeable lag. Being able to avoid that has allowed me to capture images I would have otherwise missed. The way it works is you can set a specific distance that the lens will immediately focus to if you depress the shutter. When you see that once-in-a-lifetime situation, all you need do is point the camera and press the shutter. Thanks to the wide lens and something called the hyper focal distance you can easily pick a default focus range for your situation that will properly capture anything you are likely to encounter.
There's a good reason why high-end DSLRs don't use retro mechanical controls - they are more clumsy and less flexible and you end up looking at the controls instead of the scene. The 35 mm equivalent Fuji lens (a stop faster than the Ricoh 28 mm) is also just not wide enough for street photography. I have shaky hands and was concerned about lack of image stabilization. With the APS-C sensor I can get clean images in low light at 1/125 shutter speed which eliminates the issue. Fill flash is spot on.
I have no regrets and while I wish the lens was a bit faster (f/2 would have been nice) I understand that a larger sensor meant a different lens given the small depth of the camera's body. The lens produces excellent out of focus areas when used wide open (bokeh) and has little edge to edge distortion for a wide angle lens.I have yet to experiment with all of the built-in image processing options, I'm just testing it with RAW images so far and they're excellent, deep images that are easy to process with Lightroom.For those who know what they want in a small camera, this one is certainly one to consider, the ultimate small travel/street camera for sure.
I bought the GR to complement my Canon 5D3. I had not been thrilled with the quality of other point-and-shoots that I'd owned, and I didn't want to invest in another interchangeable lens system.The GR doesn't disappoint. It's a take-anywhere camera that gives me true DSLR quality. I can pixel peep at 100% and be satisfied by the  sharpness of its images. In low-light, I feel the GR gives usable images up to ISO3200. The handling it great. It's so configurable and I've customized it so it mimics the 5D3's control system quite well, so switching back and forth between my cameras is easy for me.It's not a beginner's camera though.
Some of the features and customization's the GR has are unique to Ricoh, and can therefore be somewhat troublesome to those who are new to the Ricoh system.Once you get the settings correct, however, the camera is quick and responsive. The auto-focus on the GR is fast and does well in low light. I've read some reviews from other people who have complained about the speed of the auto-focus and the poor performance of the AF in low light conditions. Honestly, I haven't any problems with those issues at all, but maybe that is because I am using the latest firmware that might have corrected those issues.
Ricoh makes a great one, I'm sure. However, I got one from a popular online auction site at a fraction of the cost. The quality probably isn't as good and for this application it works just fine.- When I'm carrying the camera I keep the display turned off (don't need it until I change settings, thanks to the optical finder) and the camera turned on. The batteries last a very long time and the camera is always ready.A couple accessories I've found very handy are theOP/TECH USA Bin/Op Strapand theWasabi Power Battery and Charger Kit for Ricoh....
Answer: Honestly I don't think this would be the best solution for real estate photography because of the fixed focal length that's wide but not super wide. I would suggest a good entry level dslr with a wide angle lens and a decent tripod as a starting set up. If you get more serious into real estate photography,  a tilt shift lens would be a good next investment after that.
