Photoelectric, Photography Review

  • Summary: Used on my 70-200 f4 IS and Canon 40D, this converter has given very good results. The trick is to use it with the 70-200 zoomed all the way out to 200. Used this way, the images are very sharp.
  • Pros: Lends flexibility to existing compatible lenses. Lighter than getting a dedicated long telephoto lens, great image quality.
  • Cons: Image quality degrades when lens is not at full telephoto - no zooming. Pricey!

Canon 14XEF II 1.4x Extender

  • Summary: Neat little way of boosting the range of your L-glass. I've actually owned the 2x Extender as well and to be honest never really got on with that. I had sharpness issues and focusing problems, which I seem to be free of with the 1.4.

Look out for detail

  • Summary: The 1.4x extender is designed to provide that extra few mm of focal length when distance is the challenge. I bought it to add-on to the Canon 100-400mm zoom L series f5.6 lens and it works as the Canon spec says it should. It doesn't fit my Canon 70-300mm EF lens.

Very good - best with IS lenses

  • Summary: It does what it says on the box - extends the focal length by 1.4! I use it with a Canon 400D and a Canon 70-200 F4L, so it extends the range to 280 at F5.6, which isn't bad at all.

EXTENDER EF1.4X II

11 May 2009
  • Excerpt: 70-200F2.8L購入後に、Joshin Webで41,600円(ポイント4.160円分)で購入。 純正という事と、ケンコー等のテレコンに比べ値段も高いので画質には期待していたのですが正直「こんなもの?」いう感じでした。 RAW撮りで現像時にシャープネスやコントラストを調整し色にじみ等の調整でなんとか満足出来ましたがJPEG撮って出しだと不満が大きかったのは事実です。 他の方の作例を見ますと同じ70-200でもF4系は開放からでも中々の写りという印象ですが、F2.8Lの場合、開放から2絞りは欲しい感じです。...

  • Excerpt: EF135mm F2L USM EF200mm F2.8L II USM EF300mm F4L IS USM EF400mm F5.6L USM EF70-200mm F2.8L IS USM EF100-400mm F4.5-5.6L IS USM で使用しています。 思ったほど描写の劣化もなく、AFの速さも気になるほどは落ちませんでした。 長いレンズだと、マウント部の強度が気になりますが、レンズを抱えるようにして使用すれば問題ないでしょう。

  • Excerpt: 328のお助けとして、購入しました。 簡易的に画角が変更出来て、遠征時には助かります。 100−400にも使いますが、暗くなります。 割り切った使い方なら、お勧めです。

  • Summary: Produit de qualité professionnel pour usage avec des zooms série L principalement de chez canon. qualité de fabrication sérieuse . Je l'utilise sur un 70-200mm L IS F2.8 . une fois l'extender en place cela revient à un 90-280mm qui ouvre à F4.0 Je ne pense pas avoir découvert le maximum de cet...
