If your lens does not have a manual aperture control ring, it will stop down to its smallest f/stop by default.

評価がほどほど、出品者の評価を拝見し若干不安だったのですがそれを払拭するご対応で、予定よりも早く着きました。ロサンゼルスからの発送で4日ほどで東京に着きました。作りが意外としっかりしていて、三脚座もついてます。mtfマウントアダプターと比較して、こちらのほうが見た目は安っぽいですが機能的だと思います。●35mmフルサイズに着ける際は、2xエクステがついたB4レンズに、ソニーの2xテレコンを合わせて計4xにしないとケラレます。B4レンズイメージサークル(11mm)2/3インチセンサー×B4内臓EXT(2倍)×別途2倍EXT=44mm(フルサイズ35mmイメージサークル)なので焦点距離はレンズ表記の4倍になります。2倍テレコンを使うとF値が2段低下するので、レンズがF2.0だとF8.0になります。●Super35mm(APS-C)に着ける際は、以下の通りです。B4レンズイメージサークル(11mm)2/3インチセンサー×B4内臓EXT(2倍)×別途1.4倍EXT=30.8mm(Super35mmイメージサークル26.8mmをカバー)なので焦点距離はレンズ表記の2.4倍になります。1.4倍テレコンを使うとF値が1段低下するので、レンズがF2.0だとF5.6になります。

Does not work. Severe vignetting when used with wide angle b4 lens and fs7 camera in center crop mode.

Für den Preis Ok. Hat ein minimales Spiel an der Kamera. Nutze es an der FS7. Nur für HD Teleobjektive mit Verdoppler geeignet. Weitwinkel vignettieren bei Super 35. Für MFT besser geeignet.

La calidad es bastante aceptable para el precio que tiene. EL problema es que al usarla con sensores de Super35 mm el cacheo de la imagen no es valido para su uso... La intentamos usar con usa Sony FS7 pero cacheaba en el 40% del zoom de una lente Canon b$4. AL comprarla pensábamos que llevaría una lente para compensar el cacheo, pero no es asi.
