Answers to Your Most Common Questions

Q: What is the difference between APS-C and full-frame sensors?
A: APS-C sensors are smaller than full-frame sensors, resulting in a cropped field of view. This means that a 50mm lens on an APS-C camera will have a similar field of view to a 75mm lens on a full-frame camera. Full-frame sensors generally offer better image quality, particularly in low light, but they are also more expensive.
Q: What is image stabilization?
A: Image stabilization is a technology that helps to reduce camera shake, resulting in sharper images. It works by moving the sensor or lens elements to compensate for camera movement.
Q: What is weather sealing?
A: Weather sealing is a feature that protects a camera or lens from dust, moisture, and other elements. It is essential for photographers who work in challenging environments.
Q: Which system is better for wildlife photography?
A: Both systems are capable of capturing wildlife images, but the Canon EOS R7’s faster autofocus system and continuous shooting capabilities make it a better choice for action photography, including wildlife.
Q: Which system is better for landscape photography?
A: Both systems are suitable for landscape photography, but the Pentax K-1’s full-frame sensor and pixel shift resolution system offer exceptional image quality and detail, making it a preferred choice for landscape photographers.
