This lets you capture large areas of the sky in a single shot. Perfect for meteor observations, startrail photography, timelapses or capturing the Milky Way.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This compact lens fits all CS-Mount astro cameras, including the Omegon Pro veLOX and GUIDE series. Thanks to its 6.8 mm image circle, most sensors on 1.25\u2033 cameras are fully exposed. With its very bright f\/1.2 aperture, the lens is also capable of collecting a lot of light, making even fainter sky objects visible.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Built in a sturdy, anodized aluminum housing, the lens comes with protective caps on both sides to keep the glass safe during transport and storage. For stable mounting, we recommend combining it with the Omegon CMOS camera mount.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">Application<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">The Omegon CS-Mount Lens 2.5mm f\/1.2 is ideal for:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Survey shots of the night sky<\/li>\n\n\n\n<li>Startrail and timelapse photography<\/li>\n\n\n\n<li>Photography of meteors and shooting stars<\/li>\n\n\n\n<li>Weather observations and night aerial surveys<\/li>\n\n\n\n<li>Capturing the Milky Way<\/li>\n<\/ul>\n\n\n\n<h4 class=\"wp-block-heading\">Specifications<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Capacity<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Camera side: CS-Mount<\/li>\n\n\n\n<li>Focal length: 2.5 mm<\/li>\n\n\n\n<li>Aperture ratio: f\/1.2<\/li>\n\n\n\n<li>Field of view: 170\u00b0<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>General<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Material: anodized aluminum<\/li>\n\n\n\n<li>Outer diameter: 27.5 mm<\/li>\n\n\n\n<li>Length: 21 mm<\/li>\n\n\n\n<li>Weight: 20 g<\/li>\n\n\n\n<li>Color: black<\/li>\n<\/ul>","protected":false},"excerpt":{"rendered":"<p data-start=\"279\" data-end=\"569\">\u00a0<\/p>\n<p data-start=\"172\" data-end=\"277\"><strong data-start=\"172\" data-end=\"277\">Omegon CS-Mount Lens 2.5 mm f\/1.2 comes with anodized aluminum body and lens caps.<\/strong><\/p>","protected":false},"featured_media":26618,"comment_status":"open","ping_status":"closed","template":"","meta":{"_acf_changed":false},"product_brand":[126],"product_cat":[469,499,587],"product_tag":[],"class_list":["post-26615","product","type-product","status-publish","has-post-thumbnail","product_brand-omegon","product_cat-astro-fotografie","product_cat-adapters","product_cat-camera-accessoires","product_shipping_class-licht","first","instock","taxable","shipping-taxable","purchasable","product-type-simple"],"bundled_by":[],"bundle_stock_status":"instock","bundle_stock_quantity":null,"bundle_virtual":false,"bundle_layout":"","bundle_add_to_cart_form_location":"","bundle_editable_in_cart":false,"bundle_sold_individually_context":"","bundle_item_grouping":"","bundle_min_size":"","bundle_max_size":"","bundle_price":[],"bundled_items":[],"bundle_sell_ids":[],"acf":[],"jetpack_sharing_enabled":true,"jetpack-related-posts":[{"id":26631,"url":"https:\/\/staging.telescoop.nl\/en\/omegon-cs-mount-lens-28-12-mm-f-14\/","url_meta":{"origin":26615,"position":0},"title":"Omegon CS-Mount Lens 2.8-12 mm f\/1.4","author":"","date":"26-08-2025","format":false,"excerpt":"\u00a0 Omegon CS-Mount Lens 2.8-12 mm f\/1.4 comes with anodized aluminum body and lens caps.","rel":"","context":"With 1 comment","block_context":{"text":"With 1 comment","link":"https:\/\/staging.telescoop.nl\/en\/omegon-cs-mount-lens-28-12-mm-f-14\/#comments"},"img":{"alt_text":"Omegon CS-Mount Lens 2,8\u201312 mm f\/1,4","src":"https:\/\/i0.wp.com\/staging.telescoop.nl\/wp-content\/uploads\/2025\/08\/Omegon-CS-mount-objectief-2-8-12-mm-f-1-4.jpg?resize=350%2C200&ssl=1","width":350,"height":200,"srcset":"https:\/\/i0.wp.com\/staging.telescoop.nl\/wp-content\/uploads\/2025\/08\/Omegon-CS-mount-objectief-2-8-12-mm-f-1-4.jpg?resize=350%2C200&ssl=1 1x, https:\/\/i0.wp.com\/staging.telescoop.nl\/wp-content\/uploads\/2025\/08\/Omegon-CS-mount-objectief-2-8-12-mm-f-1-4.jpg?resize=525%2C300&ssl=1 1.5x, https:\/\/i0.wp.com\/staging.telescoop.nl\/wp-content\/uploads\/2025\/08\/Omegon-CS-mount-objectief-2-8-12-mm-f-1-4.jpg?resize=700%2C400&ssl=1 2x, https:\/\/i0.wp.com\/staging.telescoop.nl\/wp-content\/uploads\/2025\/08\/Omegon-CS-mount-objectief-2-8-12-mm-f-1-4.jpg?resize=1050%2C600&ssl=1 3x, https:\/\/i0.wp.com\/staging.telescoop.nl\/wp-content\/uploads\/2025\/08\/Omegon-CS-mount-objectief-2-8-12-mm-f-1-4.jpg?resize=1400%2C800&ssl=1 4x"},"classes":[]},{"id":15624,"url":"https:\/\/staging.telescoop.nl\/en\/zwo-asi-lens-28mm-12mm\/","url_meta":{"origin":26615,"position":1},"title":"ZWO ASI lens, 2.8mm -
