  • 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!

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. Of practical importance, its use is associated with a loss of 1 stop, f5.6 to f8, and this is significant because any stop higher (higher number) than f5.6 and autofocus won't work.

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. Attach it to a 300 f/2.8 or a 70-200 f/2.8 and you don't really loose much, if anything, especially on a tripod.

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. You can't really tell there's extra glass in the way either, which is impressive especially given how good the Canon L lens is.

Useful extender but a bit pricey

  • Excerpt: "...extender to go with my Canon EF 70-200 f4.0L IS lens. It extends the range to 280mm and increases the maximum aperture to 5.6. This means that autofocus on a 20D, 30D, 40D or 5D body will still function properly at any focal length. Construction ------------------ The construction is very solid (all metal) and matches the white EF-L lenses exactly so after a while you don't even notice it attached. You can easily remove the lens combo from a ...
  • Pros: Does what it says on the tin
  • Cons: A bit pricey and doesn't work with some lenses

EXTENDER EF1.4X II

  • 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。 ただサンヨンに付けた場合、印象ががらっと変わり、あたかも420mmF5.6のレンズで撮っていると言える写りです。 単焦点の望遠に関しては価格に見合う効果が有ると言えそうです。

  • 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。
