Hopefully the third version in the near future they will finally improve this issue. ### ā­ā­ā­ā­ā­ 5.0 out of 5 stars Much better after the latest firmware update *by A***R on Reviewed in the United States on February 2, 2020* After the latest firmware update, the focusing and speed is much improved. Iā€™d recommended this adaptor for canon users switching but wanting to keep a similar focal length. ### ā­ 1.0 out of 5 stars Seller misrepresents compatibility. *by L***N on Reviewed in the United States on May 27, 2020* Seller listed this product as fuji t100 compatible and it is not according to viltron customer support.This adapter is dangerous to the lens as it causes focus to spaz out and slams focus infinity.Terribly disappointed and frustrated with the seller. --- ## Why Shop on Desertcart? - šŸ›’ **Trusted by 1.3+ Million Shoppers** ā€” Serving international shoppers since 2016 - šŸŒ **Shop Globally** ā€” Access 737+ million products across 21 categories - šŸ’° **No Hidden Fees** ā€” All customs, duties, and taxes included in the price - šŸ”„ **15-Day Free Returns** ā€” Hassle-free returns (30 days for PRO members) - šŸ”’ **Secure Payments** ā€” Trusted payment options with buyer protection - ā­ **TrustPilot Rated 4.5/5** ā€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.uy/products/101341981-lens-adapter-ef-fx2-auto-focus-0-71x-speed-booster](https://www.desertcart.uy/products/101341981-lens-adapter-ef-fx2-auto-focus-0-71x-speed-booster) --- *Product available on Desertcart Uruguay* *Store origin: UY* *Last updated: 2026-04-22*
