The integrated 15mm recession solves a common mechanical problem in larger devices like the Laborator 1200 or the M800 series: The bellows often cannot be compressed enough to focus 50mm lenses (for 35mm format) on the baseboard. By mounting the lens recessed, it moves closer to the negative plane — the necessary focus range is restored.\u003c\/p\u003e\n\u003cp\u003eThe standard M39 thread fits most common enlarger lenses.\u003c\/p\u003e","brand":"Ausgeknipst","offers":[{"title":"Default Title","offer_id":50026812080468,"sku":"1447","price":29.95,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0804\/3649\/4676\/files\/DSC02195.jpg?v=1727705513","url":"https:\/\/ausgeknipst.de\/en\/products\/durst-setopla-2839-lens-board-with-39mm-thread-for-m605-601-more","provider":"Ausgeknipst","version":"1.0","type":"link"}
