Nikon Coolpix P310 vs Pentax Optio RZ18
Top 18 Reasons for the
Nikon Coolpix P310
Compared to Pentax Optio RZ18
Slightly more megapixels (photo)
0.63% more megapixels (photo)
Somewhat larger sensor
4.55 x 6.17 mm
4.56 x 6.08 mm
1.26% larger sensor. The larger the sensor the more light the sensor captures yielding in better image quality.
Measurably more focus points
90 more focus points. The more focus points the more flexibility in picking which part of the scene to focus on. They also give the image sensor a better probability in identifying the right area of the scene to focus on in more automatic modes.
Substantially faster shooting at highest resolution with AF as JPEG format
7x faster shooting at highest resolution with AF as JPEG format. Fast continuous shooting is useful for catching action shots.
Appreciably better video recording quality
1080 x 30 fps
720 x 30 fps
1.50x better video recording quality
Has a built-in HDR mode
It can automatically shoot pictures with a higher dynamic range (HDR).
Significantly higher pixel density
1.50x higher pixel density
A shade less body volume
1.61% less body volume
Sizably higher resolution
2.01x higher resolution
Has built-in optical image stabilization
Optical image stabilization uses gyroscopic sensors to detect vibrations of the camera. The lens and / or sensor move in response, adjusting the optical path. This ensures that any motion is corrected before the sensor captures the image.
Has AF tracking
With AF tracking, once you choose the subject and press the shutter release part way down, as the subject moves, the autofocus will follow it. No more out of focus shots.
2.70 mm narrower
Has a CMOS sensor
CMOS image sensors are slowly replacing CCD sensors, due to reduced power consumption and better image quality. They can be very compact and cost relatively little to produce.
Wider aperture at minimum focal length
Wider aperture at minimum focal length. With a wider aperture the sensor can capture more light, helping to avoid blur by enabling a faster shutter speed. It also provides a shallow depth of field, allowing you to blur the background to focus attention on the subject.
Has 3D photo/video recording capabilities
The device captures 3D still photos and/or 3D videos due to two separate lenses.
Has manual exposure
This allows to manually set the exposure.
Shorter minimum focal length
1 mm shorter minimum focal length. A shorter minimum focal length allows you to get more of the scene in the photo, and offers a wider angle of view than longer focal lengths.
Has manual focus
This allows to manually set the focus.
Nikon Coolpix P310 is better than Pentax Optio RZ18 because...
Top Eight Reasons for the
Pentax Optio RZ18
Compared to Nikon Coolpix P310
Vastly higher maximum light sensitivity
2x higher maximum light sensitivity. With a higher light sensitivity (ISO level), the sensor absorbs more light. This can be used to capture moving objects using a fast shutter speed, or to take images in low light without using a flash.
16 g lighter
The device can connect to WiFi.
Notably greater zoom range
13.80 x greater zoom range. The zoom range is the ratio between the longest and shortest focal lengths. A higher zoom range means that the lens is more versatile.
6 mm shorter
Sizably longer maximum focal length
350 mm longer maximum focal length. A longer maximum focal length allows you to focus in on a small part of a scene, and offers a narrower angle of view than shorter focal lengths.
Can be controlled remotely
A remote control allows you to control the device remotely. The remote control can be included or optional.
Clearly more internal storage
0.08 GB more internal storage
