It is perfect for DSLR use and requires 55mm of back focus.  No additional extension rings are required.  A large, clear aperture of 38 mm removes the chance of vignetting when used with APS-C and smaller sensors.   This reducer\/flattener has an 42 mm adapter that can be removed and replaced with an optional M48 adapter.  There is a built-in M48 filter thread; perfect for your favorite light pollution filter.  Remember that you'll need a standard M42 t-ring for your camera model.\u003cspan\u003e For Canon cameras, the depth should be 11 mm, and for Nikon cameras, it should be 8.5 mm.\u003c\/span\u003e\u003c\/p\u003e","brand":"StarField Optics","offers":[{"title":"Default Title","offer_id":39768810225777,"sku":"SFO-SF-FFR-08","price":128.95,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0851\/2766\/products\/0.8X_Reducer_FF.jpg?v=1776458913","url":"https:\/\/khanscope.com\/en-fr\/products\/starfield-0-8x-2-reducer-sf-ffr-08","provider":"Khan Scope Centre","version":"1.0","type":"link"}
