Takahashi does not publish this adapter's optical length, and that is what decides whether your train still lands on its required backfocus once everything is threaded together. Send us your corrector, spacers and camera and we will add the total up with you before you order.\u003c\/p\u003e\u003ch3\u003e\u003cstrong\u003eGood to Know Before You Order\u003c\/strong\u003e\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eOptical length is not published:\u003c\/strong\u003e every adapter contributes to the backfocus total, and if your corrector has a spacing figure to hit, that total is the number that matters.
