What is a teleconverter and how does it work
A teleconverter (sometimes called tele extender) is a secondary lens that mounts between your primary lens and your camera body. It enlarges the central part of the image made by your lens, giving you more magnification or zoom. For example, a 2x teleconverter will double the focal length of your lens, so that a 300mm lens becomes a 600mm lens.
However, using a teleconverter also has some drawbacks. The main one is that it reduces the maximum aperture of your lens by the same factor as the magnification. For example, if you use a 2x teleconverter with an f/2.8 lens, it will become an f/5.6 lens. This means that you will lose two stops of light, which can make it harder to shoot in low-light conditions or achieve shallow depth of field. Another drawback is that using a teleconverter can degrade the image quality of your lens, especially at the edges or corners. You may notice more distortion, chromatic aberration, or loss of sharpness.
There are different types of teleconverters available for different camera systems and lenses. The most common ones are 1.4x and 2x, but there are also 3x and 4x teleconverters, but they are less common and more prone to image quality issues. Teleconverters are usually designed to work with specific lenses or lens families, so you need to check the compatibility before buying one. For example, the Kenko 2x APK Teleplus MC4 teleconverter that we will discuss later is compatible with Pentax K mount lenses, but not with all of them.
What is an android apk and how to install it on your device
An android apk (short for Android Package Kit) is a file format that contains the code, resources, and metadata of an Android app. It is similar to an executable file (.exe) for Windows or a package file (.pkg) for Mac. An apk file can be downloaded from various sources on the web, such as third-party app stores, developers' websites, or file-sharing platforms. An apk file can offer some advantages over the apps that are available on the Google Play Store, such as:
Accessing apps that are not available in your region or country
Installing apps that are not compatible with your device or Android version
Getting the latest updates or features of an app before they are officially released
Trying out beta or modded versions of an app
Saving bandwidth or storage space by downloading smaller or compressed apk files
However, installing an apk file also has some risks and drawbacks, such as:
Exposing your device to malware or viruses that may harm your data or system
Violating the terms and conditions of the app developer or Google Play Store
Losing the warranty or support of your device manufacturer or carrier
Causing compatibility or performance issues with your device or other apps
Missing out on the security updates or bug fixes of the official app version
Therefore, you should only download and install apk files from trusted and reputable sources, and always scan them with a reliable antivirus app before opening them. You should also backup your data and system before installing any apk file, in case something goes wrong.

How to use a 2x apk teleplus mc4 with your Android device
Now that you know what a teleconverter and an apk file are, and how to install them on your device, let's see how you can use a 2x apk teleplus mc4 with your Android device. This is a specific model of teleconverter made by Kenko, a Japanese company that specializes in camera accessories. It is designed for Pentax K mount lenses, which are compatible with Pentax DSLR cameras and some mirrorless cameras with adapters.
The Kenko 2x APK Teleplus MC4 teleconverter has the following features and specifications:- It has a 2x magnification factor, which means that it doubles the focal length of your lens
- It has a 4-element, 4-group optical design with multi-coated elements to reduce flare and ghosting
- It has an AF (autofocus) function that works with most Pentax K mount lenses, but not all of them
- It has a DGX (digital) function that communicates the effective aperture and focal length to the camera body
- It has a MC4 (multi-coated 4) function that improves the light transmission and contrast of the image
- It has a KAX (K mount automatic) function that supports the automatic exposure modes of the camera body
- It weighs 111 grams and measures 26 x 24 mm
To use the Kenko 2x APK Teleplus MC4 teleconverter with your Android device, you need to have a Pentax K mount lens and a compatible camera body. You also need to have an adapter that allows you to connect your camera body to your Android device via USB or Wi-Fi. For example, you can use the Pentax Image Sync app and the Pentax O-FC1 FluCard to remotely control your camera and transfer images to your device. Alternatively, you can use the DSLR Controller app and a USB OTG cable to connect your camera and device directly.
Once you have the necessary equipment, you can follow these steps to use the teleconverter with your Android device:
Attach the teleconverter to your lens by aligning the red dots and twisting it clockwise until it locks. Make sure that the teleconverter is securely attached and that there is no gap between it and the lens.
Attach the lens with the teleconverter to your camera body by aligning the red dots and twisting it clockwise until it locks. Make sure that the lens is securely attached and that there is no gap between it and the camera body.
Turn on your camera and set it to manual focus mode. This is because the autofocus function may not work well with the teleconverter, especially in low-light conditions or with slow lenses. You can use the focus ring on your lens or the focus peaking feature on your camera to manually adjust the focus.
Set your camera to manual exposure mode or aperture priority mode. This is because the teleconverter reduces the amount of light that reaches the sensor by two stops, so you need to compensate for that by adjusting the aperture, shutter speed, or ISO. You can use a light meter or the exposure indicator on your camera to find the correct exposure settings.
Connect your camera to your Android device using the adapter of your choice. For example, if you are using the Pentax Image Sync app and the Pentax O-FC1 FluCard, you need to insert the FluCard into the SD card slot of your camera and turn on the Wi-Fi function on both devices. Then, you need to launch the app on your device and select your camera from the list of available devices. If you are using the DSLR Controller app and a USB OTG cable, you need to connect one end of the cable to your camera's USB port and the other end to your device's USB port. Then, you need to launch the app on your device and grant the necessary permissions.
Use your Android device as a remote control or a monitor for your camera. You can use the app of your choice to adjust the settings, take pictures, record videos, review images, or transfer files. You can also use the app to zoom in or out, change the focus point, or trigger the shutter.
