In this article I want to introduce to you to the Nokia Lumia 830 rear facing (main) camera, so you can learn more about it’s advantages and understand it’s key specs.The Nokia Lumia 830 mid-range smartphone was announced on September 4th 2014 on IFA 2014 Berlin, Germany.
Before we jump talking about it’s key specs in more depth, let’s first take a look at the detailed camera specs.

The Lumia 830 main cameras is embedded in a mid-range smartphone. Nokia wanted to make this device attractive by enhancing its imaging capabilities. For example, the Lumia 830 has a dynamic flash feature, in which the camera takes two sequential photos (one with flash, the other without) and therefore allows you to choose which one you like best. You have the option to also manually adjust the shutter speed, exposure and ISO to give you more control over the final output (vs fully automatic). The phone is prices around €330 (~US$430) and is available in four difference colors, including black, orange, white and green. The phone itself is made of a metal-edge body that adds to the looks and feel of the phone.
OK, not let’s talk more about the Lumia 830 camera.
The Lumia 830 rear camera boasts some excellent specs and was designed to give a good deal of competition against some of the higher end smartphone cameras. In fact, in IFA 2014 press conference, Nokia shows how the Lumia 830 compared to the iPhone 5S, and we can see that the Lumia 830 image is much brighter than the iPhone 5S image (taken in a low-light situation, check out the video below minute 19:30).
The good news is that those of you who want a phone with a high-quality camera and cannot afford buying a high-end smartphone, the Lumia 830 might be your best option yet.
Looking at the Nokia Lumia 830 camera specs, we can see that it boasts some very impressive specs. First of all, the main camera utilizes a 1/3.4″ (4.23 x 3.17 mm) size BSI CMOS sensor. Let’s see how it compares to some other camera phones on the market:
- Nokia Lumia 1020: 1/1.5″ (~8.80 x 6.60 mm) | 41MP | BSI | 1.12 micron pixel size
- Nokia Lumia 520: 1/4″ (~3.20 x 2.40 mm) | 5MP | FSI | ~1.24 micron pixel size
- Apple iPhone 4S / Samsung Galaxy S3: 1/3.2″ (~4.54 x 3.42 mm) | 8MP | BSI | 1.4 micron pixel size
- Apple iPhone 5S: 1/3″ (~4.80 x 3.60 mm) | 8MP | BSI | 1.5 micron pixel size
- Samsung Galaxy S5: 1/2.6″ (~5.08 x 4.81 mm) | 16MP BSI | 1.12 micron pixel size
We can see that the Lumia 830 sensor is slightly smaller than that of the 5S and S5 and significantly smaller than the Lumia 1020, but larger than the Lumia 520 for example and uses BSI technology (Backside-illuminated), not FSI.
The camera is equipped with high-quality Zeiss optics, a wide-angle f/2.2 fast lens. The combination of an optical image stabilization, fast aperture lens, back-illuminated sensor and LED Flash, all allow the camera to perform very well in low light. The large high-quality display makes it easy to compose your shots, even in bright daylight. The end result are sharp, high-contrast, clear beautiful looking images and videos.
The most interesting feature in my opinion is the addition of an optical image stabilization, and this is a newly developed one, which is the thinnest Nokia ever produces. This allows Nokia toe maintain a thin phone profile. The optical image stabilization mechanism is a sensor-shift based IBIS, which was designed to compensate for hand movements. This allows the camera to take sharp images, especially when shooting in low-light. Why in low-light you ask? — well, when you capture an image in low lighting conditions, the camera (in auto mode) or the photographer (manual mode) need to do a few things: use faster aperture, increase the ISO speed and/or reduce the shutter speed.
Increasing the ISO is not the best option ad it leads to increase of image noise the further you boost the ISO speed. Using a faster aperture can help, but sometimes you shoot already using the maximum aperture (smallest f-number), therefore you only other best option is to reduce the shutter speed. The problem with reducing the shutter speed is that it can lead to image blur, depends on how well the camera is stabilized and the focal length. In order to enjoy sharp images, you should shoot at a shutter speed that is at a shutter speed at least the 1/focal length. A lower shutter speed than that can lead to a blurry image.
What the optical image stabilization does is it allows you to shoot a few stops (slower shutter speeds) lower than the recommended shutter speed for a given focal length (if you follow the shutter speed rules of thumb). One f-stop of shutter speed results in twice the amount of light passing through the lens and reaching the sensor, significantly enhancing the light gathering capabilities of the camera and improving the low-light performance.
This is also true to video, although in video the effect is also related to the camera movement while shooting videos. This minimize the shakiness effect that you might encounter in amateur filmed videos on the web, taken with cameras or smartphone that lacks an optical IS mechanism.
I’m still waiting for early Nokia Lumia 830 sample images and comparison reviews, but all in all, the Lumia 830 camera looks very promising indeed. I think that finally more people can afford having a high-quality mobile phone camera without paying a premium price for a device to enjoy it.
