As a mid-range handset, the Desire 816 doesn't use HTC's flagship âUltraPixelâ sensor or Duo Camera arrangement, instead relying on a more traditional 13-megapixel CMOS. The sensor is a 1/3.06â OmniVision OV13850, which uses 1.12Âµm pixels and natively captures 4:3 images with a resolution of 4224 x 3136. Itâs paired with a 28mm-effective f/2.2 lens and an LED flash.
Meanwhile the front camera is a Samsung S5K5E2 1/5â 5-megapixel CMOS with 1.12Âµm pixels, paired with an f/2.8 33mm-effective lens. Both the front and rear cameras are identical to the HTC One mini 2, while the front sensor is also the same as the HTC One M8 (albeit with a different lens). Itâs interesting that HTC has used a wider-angle lens for the rear camera than the front-camera, but both are wide enough for general use.
OmniVisionâs smartphone camera sensors tend to be more on the budget end of the scale, compared to high-end models from Sony and Samsung. With that said, the OV13850 is a perfectly capable shooter for a mid-range product like the Desire 816, and throughout my use I found it to be quite good for everyday photography.
One of the strengths of the HTC Desire 816âs camera is the resolution. The 13-megapixel sensor captures a decent amount of detail for a mid-range smartphone, surpassing HTCâs own flagaship One M8 with its smaller 4-megapixel shooter. In the best conditions, the Desire 816 produces crisp results that look great when downscaled to 1080p or 720p, and thereâs ample room for some cropping or zooming.
The OV13850 isnât without grain though, noticeable when viewing full resolution shots captured using most of the cameraâs ISO range. The Desire 816âs camera metering algorithm prefers to use ISO 125 for the majority of its shots, which doesnât really suffer from noticeable grain. Itâs odd that it never used a lower ISO though, even in the brightest of conditions, instead using progressively faster shutter speeds that easily reached 1/2000s.
The color quality seen in the Desire 816âs camera shots is good without being astonishing, often suffering from typical HTC camera problems like underexposure in cloudy situations and dodgy indoor white balance. Photos taken outside were usually fine though, with acceptable dynamic range that can be boosted using the HDR mode when photographing high-contrast scenes.
The use of a 13-megapixel sensor over the UltraPixel camera module has its downsides when shooting in dark conditions. 1.12Âµm pixels arenât adequate enough when paired with an f/2.2 lens to produce bright images at night. The camera has to resort to using high ISOs to reduce blur and capture enough light, and anything past ISO 800 will cause high levels of grain and noise reduction artefacts.
I wasnât impressed with the Desire 816âs camera preview, which uses a low frame rate that doesnât give a smooth experience at all. If youâre moving the camera about, it can cause the preview to be blurry, even in strong sunlight. HTC also uses spot metering, adjusting for wherever you tap to focus, which has its upsides and downsides but unfortunately canât be changed to matrix or center-weighted metering.
On a more positive note, thereâs a very short capture time, allowing you to capture images almost instantly.
Compared to HTCâs flagship product line there are fewer camera features: the Desire 816 only has the basics like crude exposure and ISO adjustment, plus a range of typical scenes. Manual shooting mode is gone, so thereâs no way to make fine adjustments to the camera settings, as is Zoe mode and everything related to the Duo Camera.
The 5-megapixel front-facing selfie camera is good as far as front-facing cameras go, but itâs definitely a few steps behind the rear camera. Itâs surprisingly capable in low-light for a module using an f/2.8 lens, and the resolution makes your selfies quite detailed, but actual color quality leaves a lot to be desired.
The Desire 816 is capable of recording video at 1080p at 30 frames per second and with a bitrate of 20 Mbps. Quality of both the video and audio is good, with color saturation and dynamic range on par with still shots.
