The budget dual camera smartphone battle

Dual camera phones - not only are they becoming more common but they're also becoming a lot more affordable. Price revisions and new contenders under the Rs 15,000 mark mean that everyone can enjoy the shallow focus and bokeh effects that dual cameras are known for

Lenovo K8 Note (Rs 12,999 onwards)

The K8 Note is the first device from Lenovo to come with a dual camera system and that too on a budget. The phone has a 13MP + 5MP dual camera setup which enables a user to go as low as f1.2 aperture via the camera interface for bokeh effect.

A 4,000mAh battery powers K8 Plus that the company claims would last two days.Lenovo K8 Plus is a compact version of the Lenovo K8 Note. It comes with a similar dual camera setup - 13MP + 5MP and has a dual-tone LED flash.

One of the cameras only captures monochrome, serving to add detail to info from the primary. It also has shallow depth portrait and you can adjust the aperture level and area of focus after capturing the photo.

Common Questions Answered

For Cameras - Are Two Heads Better Than One?

For decades, we've been told that SLR and large format cameras are the best at photography. It simply has to do with size (of the film -and later, of the image sensor). Size wins in a traditional world but smartphones are anything but. Particularly in the camera department, manufacturers have found clever ways to eke out better quality every year. This explains why dual (and triple and quad...) cameras are a trend.

Having multiple sensors and lenses can overcome some of the limitations of a smartphone - a device that has to be thin, light, efficient and durable. In fact, the technology exists to make a camera with 16 sensors and lenses.The Light L16 camera is only sl ightly larger than a 5.5-inch smartphone but claims to capture DSLR-beating, 81 Megapixel photos. That's the next step for smartphones. It won't end with just two cameras, that's for sure.

Budget Dual vs Premium Dual - What's The Difference?

Just slapping on an extra lens does not mean you'll instantly get better photos. Plus, there are different approaches to the dual camera setup. One approach is to have two lenses of different focal lengths so that you can zoom in on a subject.

Another approach is to have one ultra-wide angle lens to offer an interesting perspective. Or the secondary camera could be monochrome, simply capturing additional light, which is to be merged with the results from the main camera for better overall quality.Whatever the approach, the kind of sensor used (size of pixels, size of sensor, quality), lens quality aperture and image processing engine algorithms go a long way in determining image quality.

Why Better Quality? Aren't Smartph one Cameras Good Enough?

Not by a long shot. Most of them still struggle to capture good photos in low light. And when you compare the noise levels and resolving power of a smartphone with a DSLR, there's still a massive difference. According to a recent report by analytics firm InfoTrends, of the roughly 1200 billion digital photos that are going to be captured by the end of 2017, 85% of those photos will be captured by smartphones.

Only 10.3% of those photos will be taken by digital cameras and that number is falling. Once you recognise this irreversible trend, you'll understand why the multi-camera is here to stay.
