Which Focus Lenses

Postby practicing01 » Fri Jul 14, 2017 1:16 am

Hello, what're the best/cheapest lenses to buy for shrinking the projector image? I was using two cheap magnifying glasses some time ago but want something better. I found this: https://www.muve3d.net/press/product/52 ... projector/ but $20 seems pricey. Thanks for any help or links.

Edit: Found this on ebay: http://www.ebay.com/itm/52-67-72-77mm-C ... M-oTG5KpuQ much cheaper :)
