De reducing factor is 0.7x op beide telescopen. Het brandpunt van de FRA400 wordt dan 280mm met een brandpunt ratio van f\/3.9. Voor de FRA500 wordt het brandpunt 351mm met een brandpunt ratio van f\/3.9. Backfocus van de 0.7x reducer is 55mm hierdoor kan je de meeste camera&#8217;s prima monteren.<\/p>\n<p>De reducer beschikt ook over een mogelijkheid om 2 inch filters te monteren. Het filter kan je monteren in de adapter die eindigt op M48. Deze schroef je van de reducer af en kan je aan de binnenkant het filter schroeven. Elk filter met M48x0.75 schroefdraad, dit is standaard, past in de adapter.<\/p>\n<p><a href=\"https:\/\/www.ganymedes.nl\/wp-content\/uploads\/2024\/07\/Askar-FRA400_500_reducer_2.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone wp-image-45767 size-vp_md\" src=\"https:\/\/www.ganymedes.nl\/wp-content\/uploads\/2024\/07\/Askar-FRA400_500_reducer_2-800x573.jpg\" alt=\"\" width=\"800\" height=\"573\" srcset=\"https:\/\/dev4-ganymedes.nl\/wp-content\/uploads\/2024\/07\/Askar-FRA400_500_reducer_2-800x573.jpg 800w, https:\/\/dev4-ganymedes.nl\/wp-content\/uploads\/2024\/07\/Askar-FRA400_500_reducer_2-324x232.jpg 324w, https:\/\/dev4-ganymedes.nl\/wp-content\/uploads\/2024\/07\/Askar-FRA400_500_reducer_2-416x298.jpg 416w, https:\/\/dev4-ganymedes.nl\/wp-content\/uploads\/2024\/07\/Askar-FRA400_500_reducer_2-300x215.jpg 300w, https:\/\/dev4-ganymedes.nl\/wp-content\/uploads\/2024\/07\/Askar-FRA400_500_reducer_2-768x550.jpg 768w, https:\/\/dev4-ganymedes.nl\/wp-content\/uploads\/2024\/07\/Askar-FRA400_500_reducer_2-140x100.jpg 140w, https:\/\/dev4-ganymedes.nl\/wp-content\/uploads\/2024\/07\/Askar-FRA400_500_reducer_2-500x358.jpg 500w, https:\/\/dev4-ganymedes.nl\/wp-content\/uploads\/2024\/07\/Askar-FRA400_500_reducer_2.jpg 805w\" sizes=\"auto, (max-width: 800px) 100vw, 800px\" \/><\/a><\/p>\n<h3>Levering van de Askar F3.9 full frame reducer voor FRA400 en FRA500 omvat:<\/h3>\n<ul>\n<li>Full Frame reducer 0.7x voor Askar FRA400\/500<\/li>\n<\/ul>\n<h4>Plaats je bestelling online of kom langs in de winkel<\/h4>\n<p>Heb je gevonden wat je zoekt en wil je bijvoorbeeld de Askar 0.7x reducer bestellen?
