Design

1.weather-sealed (splashproof)
Nikon D7100
Pentax K-3
The device is protected with extra seals to prevent failures caused by dust, raindrops, and water splashes.
2.Has a built-in focus motor
Nikon D7100
Pentax K-3
The focus motor moves the lens in order to autofocus. For system cameras, having a focus motor in the camera's body allows you to use a wide range of lenses, including lenses which do not have their own focus motor. For compact cameras, a focus motor is usually built-in.
3.weight

675g

800g

We consider a lower weight better because lighter devices are more comfortable to carry. A lower weight is also an advantage for home appliances, as it makes transportation easier, and for many other types of products.
4.has an optical viewfinder
Nikon D7100
Pentax K-3
An optical viewfinder (or OVF) allows the photographer to compose a shot while seeing exactly what the lens will capture. OVFs have no time lag and require no power - as opposed to electronic viewfinders, which can drain battery life. OVFs are also better in low light situations.
5.Has a hot shoe
Nikon D7100
Pentax K-3
A hot shoe can be used to attach an external flash, as well as light meters, viewfinders, rangefinders and other attachments.
6.resolution

1280 x 960px

1280 x 854px

Resolution is an essential indicator of a screen's image quality, representing the maximum amount of pixels that can be shown on the screen. The resolution is given as a compound value, comprised of horizontal and vertical pixels.

Optics

1.sensor size

23.5 x 15.6mm

23.7 x 15.7mm

The larger the sensor the more light the sensor captures yielding in better image quality.
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.
The number of megapixels determines the resolution of the images captured with the main camera. A higher megapixel count means that the camera is capable of capturing more details. However, the megapixel count is not the only important element determining the quality of an image.
4.maximum light sensitivity

25600 ISO

51200 ISO

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.
Fast continuous shooting is useful for catching action shots.
6.has AF tracking
Nikon D7100
Pentax K-3
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.

Videography

1.video recording (main camera)

1080 x 30fps

1080 x 60fps

The maximum resolution available for videos shot with the main camera. Although it may be possible to choose among other frame rates, those recordings usually have lower resolutions.
A phase-detection autofocus system is faster than a contrast detection autofocus system. Even when recording scenes with a lot of fast movements, the videos are sharp and clear.
When recording movies they stay focussed and sharp.
4.Has timelapse function
Nikon D7100
Pentax K-3
A timelapse shows a long passage of time sped up. A series of photographs taken from the same position over a long period is joined together to create a short video. It is great way to capture things like the setting sun, or clouds moving across the sky.
5.has a 24p cinema mode
Nikon D7100
Pentax K-3
24p is a video format (24 frames per second) traditionally used in cinema. Nowadays, it is used to create film-like motion characteristics.

Audio

1.has a stereo microphone
Nikon D7100
Pentax K-3
A stereo microphone allows to record audio files or movies in stereo without an external microphone.
2.has a microphone input
Nikon D7100
Pentax K-3
A microphone port allows connecting external high-end or specialized microphones.
More microphones result in better sound quality and enable the device to filter out background noise.
With a standard mini jack socket, you can use the device with most headphones.

Battery

1.Battery life (CIPA)

950shots

560shots

CIPA is an independent, standard measurement that determines how many shots a camera can take before the battery dies.
2.has a removable battery
Nikon D7100
Pentax K-3
The battery is removable and can be replaced by the user if broken.
3.has a rechargeable battery
Nikon D7100
Pentax K-3
The battery can be recharged and used over again.
4.has a battery level indicator
Nikon D7100
Pentax K-3
An indicator shows you when the device has low battery.
5.battery power

1900mAh

2000mAh

Battery power, or battery capacity, represents the amount of electrical energy that a battery can store. More battery power can be an indication of longer battery life.

Features

1.Has a remote control
Nikon D7100
Pentax K-3
A remote control allows you to control the device remotely. The remote control can be included or optional.
2.has an external memory slot
Nikon D7100
Pentax K-3
The device has a standard memory slot (such as an SD or micro SD card slot) that enables you to extend the built-in internal storage with affordable memory modules, or easily retrieve data, such as photographs, from the memory card.
3.has an HDMI output
Nikon D7100
Pentax K-3
Devices with a HDMI or mini HDMI port can transfer high definition video and audio to a display.
4.Has dual card slots
Nikon D7100
Pentax K-3
It has two memory card slots, allowing you to store more photos without switching cards. This is particularly useful on long shoots when you need more space.
5.has an accelerometer
Nikon D7100
Pentax K-3
An accelerometer is a sensor used to measure the linear acceleration of a device. A common application is detecting when a device changes between vertical and horizontal positions.
Newer USB versions are faster and have better power management.
