I'm selling a used Kenko 1.4x Teleplus Pro 300 DGX MC4 Autofocus Teleconverter for EOS SLRs and DSLRs on eBay UK. This was designed for full frame and is suitable for EF mount lenses only - EFs lenses such as 18-55 won't fit because the rear element protrudes too far, but it should be OK with lenses that are designed for the APSc format but have an EF-style mount, e.g. many third party lenses, and the magnification is about right for using them on full frame. It works well with a 50mm Yongnuo AF lens, and there are some photos in the listing, I don't currently have anything else that fits. Current bid is £1.99 plus P&P; £3.89 in the UK, more overseas. Ends Sunday Oct 3rd 19:30 BST https://www.ebay.co.uk/itm/135282515954
