The EVO 4G features a similar (if not identical) camera to the HTC Incredible with an 8 megapixel sensor, an auto-focus lens with macro, and dual LED flash.
The biggest upgrade from the Incredible to the EVO 4G is the addition of face detection for stills, and HD video recording. All the other great features, such as extra camera settings, touch-to-focus, and initial auto-focus for video remain.
When using touch-to-focus, the EVO 4G adjusts exposure in all modes, whereas the Incredible only adjusts exposure in “spot” mode. This often causes unwanted under- or over-exposure, and makes the feature problematic.
Like the Incredible, low-light performance is rather impressive with the EVO 4G, as long as it’s bright enough for the auto-focus (there’s no AF assist light, strangely).
Color balance is sometimes off with the EVO 4G, but there’s none of the default over-sharpening present on the Incredible. Also, when taking macro shots, the EVO 4G struggles to focus more often than the Incredible.
On the plus side, the EVO 4G saves the flash mode between sessions, while the Incredible always resets the flash mode to “auto”. This matters to me as I almost never use the flash, so I prefer to leave it in the “off” position.
Also, the EVO 4G’s monster 4.3″ TFT screen is more readable in direct sunlight than the 3.7″ OLED display on the Incredible, making it easier to frame shots.
Most of these differences can be attributed to firmware, which can be easily updated. My EVO 4G is from the batch handed out at the Google I/O conference – retail units may ship with newer firmware.
The only major bug I’ve encountered with the EVO 4G camera is that it randomly stops seeing the micro-SD card and refuses to take pictures. This can be fixed by rebooting the phone, which is far from ideal. The Incredible camera is rock solid in comparison.
As far as video recording is concerned, the EVO 4G supports up to 1280×720 @ 25 fps (HD), but there’s a lot of compression artifacts at this resolution, especially in scenes with a lot of motion.
You may be better off switching down to 800×480 @ 30 fps (WVGA), which is the Incredible’s best setting.
Here’s a sample video (download original, 1280×720 @ 25 fps):
In the end, the EVO 4G camera is very good, and will be fantastic when/if newer firmware fixes some of the aforementioned problems.
For the time being, the Incredible remains king of the (Android) hill in terms of camera performance.
Now if I could only convince HTC to put a dedicated two-stage camera button on all its devices, that would be nice :)
