Their disadvantages are higher power consumption and slower operation compared to newer solutions. Cameras using a CCD matrix include, for example, the Leica M9, Nikon D3X, Kodak DCS Pro SLR\/c, Nikon D3 or the professional PhaseOne P65+.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">CMOS Matrix<\/h3>\n\n\n\n<p>The most common matrix type is the CMOS (Complementary Metal-Oxide Semiconductor). It is characterised by low power consumption, fast operation and lower production costs. CMOS matrices match and often exceed the quality of older CCD matrices. Cameras with CMOS sensors include the Canon R5 (45MP), Sony A7R V (61MP), Nikon Z9 (45.7MP), Fujifilm GFX 100S (102MP) or Sony A1 (50MP).<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" width=\"800\" height=\"533\" src=\"https:\/\/marszalstudio.pl\/wp-content\/uploads\/2025\/01\/matryca-aparatu-5.webp\" alt=\"camera sensor 2\" class=\"wp-image-6419011\" title=\", Zdj\u0119cie\" srcset=\"https:\/\/marszalstudio.pl\/wp-content\/uploads\/2025\/01\/matryca-aparatu-5.webp 800w, https:\/\/marszalstudio.pl\/wp-content\/uploads\/2025\/01\/matryca-aparatu-5-300x200.webp 300w, https:\/\/marszalstudio.pl\/wp-content\/uploads\/2025\/01\/matryca-aparatu-5-768x512.webp 768w\" sizes=\"(max-width: 800px) 100vw, 800px\" \/><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"sensor-sizes\">Sensor Sizes<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\">Main Sensor Formats:<\/h3>\n\n\n\n<ul class=\"wp-block-list\"><li><strong>Full Frame<\/strong> (full frame) - size 36x24mm<\/li>\n<li><strong>APS-C<\/strong> - approximately 23.6x15.7mm (Canon 22.2x14.8mm)<\/li>\n<li><strong>Micro 4\/3<\/strong> - 17.3x13mm<\/li>\n<li><strong>1 inch<\/strong> - 13.2x8.8mm<\/li>\n<li><strong>Smartphone matrices<\/strong> - typically under 1 inch<\/li>\n<\/ul>\n\n\n\n<!-- BANNER CHECK ALSO -->  <a href=\"https:\/\/marszalstudio.pl\/en\/film-camera-analog-photography\/\" class=\"checkalso-baner\">   <img decoding=\"async\" class=\"checkalso-eyes-icon\" src=\"https:\/\/marszalstudio.pl\/wp-content\/uploads\/2025\/02\/eyes-icon.webp\" alt=\"Ikona oczu\" title=\", Zdj\u0119cie\">   <div class=\"checkalso-baner-center\">     <span class=\"checkalso-tekst1\">Check also:<\/span>     <span class=\"checkalso-tekst2\">       <span class=\"checkalso-podkreslenie\">Film Camera: Return to Analogue Art<\/span>     <\/span>   <\/div>   <div class=\"checkalso-baner-right\">       <div class=\"checkalso-strzalka\">\u279c<\/div>     <\/div>   <\/a>\n\n\n\n<p>The size of the sensor has a key impact on image quality, especially in <a href=\"https:\/\/marszalstudio.pl\/en\/what-is-ISO-in-photography\/\">low light<\/a>.

Today's sensors offer resolutions from 20 to even 100 megapixels. However, the number of megapixels alone does not determine the image quality.<\/p>\n\n\n\n<!-- BANNER CHECK ALSO -->  <a href=\"https:\/\/marszalstudio.pl\/en\/mirrorless-best\/\" class=\"checkalso-baner\">   <img decoding=\"async\" class=\"checkalso-eyes-icon\" src=\"https:\/\/marszalstudio.pl\/wp-content\/uploads\/2025\/02\/eyes-icon.webp\" alt=\"Ikona oczu\" title=\", Zdj\u0119cie\">   <div class=\"checkalso-baner-center\">     <span class=\"checkalso-tekst1\">Check also:<\/span>     <span class=\"checkalso-tekst2\">       <span class=\"checkalso-podkreslenie\">Top Mirrorless Cameras for 2026: Expert Guide<\/span>     <\/span>   <\/div>   <div class=\"checkalso-baner-right\">       <div class=\"checkalso-strzalka\">\u279c<\/div>     <\/div>   <\/a>\n\n\n\n<p>What is crucial is the size of the individual pixel. On a sensor of the same size, more megapixels means smaller pixels, which can result in more noise and poorer quality in low light. For most applications, a image sensor of 24-26MP offers the optimum compromise between resolution and image quality.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"sensor-life\">Sensor Life<\/h2>\n\n\n\n<p>The average life of the sensor is around <strong>100,000 - 200,000<\/strong> shutter releases, although many cameras exceed these figures. Professional models are often tested to <strong>300,000 - 500,000 <\/strong>triggers.<\/p>\n\n\n\n<p>The camera sensor itself rarely wears out - more often the camera mechanics fail. However, it is worth bearing in mind that intensive use in high temperatures or in bright sunlight can shorten the life of the sensor.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"800\" height=\"533\" src=\"https:\/\/marszalstudio.pl\/wp-content\/uploads\/2025\/01\/matryca-aparatu-7.webp\" alt=\"camera sensor 4\" class=\"wp-image-6419020\" title=\", Zdj\u0119cie\" srcset=\"https:\/\/marszalstudio.pl\/wp-content\/uploads\/2025\/01\/matryca-aparatu-7.webp 800w, https:\/\/marszalstudio.pl\/wp-content\/uploads\/2025\/01\/matryca-aparatu-7-300x200.webp 300w, https:\/\/marszalstudio.pl\/wp-content\/uploads\/2025\/01\/matryca-aparatu-7-768x512.webp 768w\" sizes=\"(max-width: 800px) 100vw, 800px\" \/><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"does-sensor-size-still-matter\">Does Sensor Size Still Matter?<\/h2>\n\n\n\n<p>Definitely yes.
