I am extremely new to film making and have recently purchased a 1k(Type 407) and two 650(Type 4821) Mole-Richardsons on ebay. None of them came with barndoors and I realize now its very difficult to come across barndoors for these specific models on Ebay. I fear I might have to purchase them new and they are expensive. A four leaf barndoor for the tweenies are $64 a piece on bhphotovideo and the 1k isn't even on their but appears to go for around $15 more on various sites. Any recommendations would be great I searched the forums and was unable to come up with anything. Also if there is no way out of purchasing Mole-Richardson brand barndoors is there a site which would be recommended? I appreciate any advice, thankyou.
