This is my 2nd product I've purchased from Viltrox. The first one was for their EF to EF-M speedbooster. This one was for my EFS to EFM use. Way cheaper than the Canon version, and works great. No problems at all with mounting and AF.

What can I say! It's a Canon body cap that will fit any canon camera with EF anf EF-S mount, doesn't matter if it's a full frame, APS-C, or film. In other words, if your camera was made in the last 30 years, this cap will fit!

This worked perfectly for my EOS R to use my EF lenses.

7Dと必要なものをコンパクトにまとめて持ち歩くために購入しました。本製品に関していい点・軽い・安い・仕切りは自分で組み替えられる・中がオレンジなので、暗くてもみやすい悪い点・全体的に柔らかい・上の荷物入れの部分が小さめ（バッテリーグリップと小さなレンズなら余裕で入りますが、その他小物を入れようとするときつい）・上の荷物入れ内にあるメッシュポケットは小さくて、使いにくい、実際に入れても出てしまったりする。・外のメッシュポケットが小さめで、ペットボトルのホールド性は良くない実際に入れた感じは［下のメイン収納には］・7D＋EFS18-200／レンズフード／ハンドストラップとネックストラップ付き・EF75-300mm F4-5.6 IS USM （バッグの幅よりレンズの方が少し大きいですが入ります）・シグマ　フラッシュ　EF-610 DG 　（大型のフラッシュ／少し幅より大きいですが入ります）・隙間にフィルターいくつか入れました［上の小さな空間には］・バッテリーグリップ・予備バッテリー×2・EF50mm F1.8 II・フラッシュ用予備　単三電池×4・予備のフラッシュメモリ・小型のメモ帳・小型のポーチーーーーーーーーーーーーーーーもっといっぱい持っていきたいという気持ちを抑えて厳選すれば、そこそこ使えると思います。持てる機材を全て持ち出す事は出来ないと思いますが、目的が決まっていたり、特にスナップ撮影目的なら十分な大きさだと思います。

This is a great product to go along with the Akaso EF7000 Camera!

Very nice quality. Happy to use all my old EF-S lenses.

Fantastic upgrade in all ways to the EOS-M. Is definitely on par with other mirrorless options.+LCD screen very bright, even in sunlight+rotating LCD so can selfie-shot and also shoot from low down/on ground / holding above your head if in a crowd+add on external viewfinder came with my combo package and it works great+much improved hand grip+autofocus speed much faster than original EOS-M. Most noticeable in native EF-M lenses and STM lenses - other lenses still not that fast.I've personally used the EF 50mm f1.8, 40mm f/2.8, EF-M 22mm, kit lens, EF-M 55-200, EF 24-105L - All have VERY fast and SLR speed autofocus. It WHIPS them into focus! I'm very happy!+I love that I can swap my load-out for my needs - are you going H.C. Bresson style? Let's go with the native 22mm or EF 40mm and no viewfinder. Doing a semi-pro outdoor engagement session? Slide on the external viewfinder, and mount your 24-105L!+Battery life improved compared to original EOS-MOverall, a great camera. Its photo quality continues to perform at SLR quality. Especially for a lower price point compared to some micro 4-3rds cameras and mirrorless, I think its a great deal.

Sharp, light and small. As fast as it gets on an ef M zoom.
