None
LOW-PASS FILTERA low-pass filter blurs fine details of an image to eliminate the moiré and the color artifacts of finely patterned structures. Without a low-pass filter images will appear sharper, but there is also a risk of moiré occurring in certain scenes.

?A good landscape camera should offer high resolution and wide dynamic range; it should also be weather-sealed.
?Excellent autofocus and high-ISO performance, high continuous shooting speed and good buffer capacity are crucial for a good sports & action camera. Weather-sealing is an advantage.
?Cameras for available light photography should maintain a good image quality when shooting at high ISO settings and have an efficient autofocus in low-light conditions.
?Cameras for "connected life" should be lightweight, not too big and offer touch screen as well as built-in WiFi and Bluetooth.
?These cameras are good for beginners. They combine good image quality with affordability and a basic set of features.
