Cant spend $ + for a Prime Lens get an extender

  • Excerpt: I use the 1.4x with my Canon EF 100-400mm f/4.5-5.6L IS II USM Lens. This allows me to capture birds in flight at 560mm on my full frame Canon 6d. You sacrifice an f-stop in light. So far with this combination I cannot autofocus I've only been able to achieve only manual focus.
  • Pros: Compact, Consistent Output, Durable, Easily Interchangeable, Lightweight, Rugged, Strong Construction, Tack Sharp Photos
  • Cons: No Autofocus

Good Product

  • Excerpt: Upgraded from the 1.4X II to use with Canon 300mm 2.8 IS II and 1D X. Was hoping to see better IQ from II to III, but on still subjects, not seeing it. Hopefully, AF will be a little faster on moving objects which I haven't had the opportunity to try yet.
  • Pros: Durable, Rugged, Strong Construction

  • Excerpt: -I use this extender when taking photos of skiers -It does not degrade photo quality, and does the job of extending beautifully. -Unfortunately focusing with this extender is more difficult. Occasionally photos will be soft or completely out of focus.
  • Pros: Consistent Output, Durable, Easily Interchangeable, Lightweight, Strong Construction

Great accessory

  • Excerpt: Having a buch of fixed focal length lenses in your bag is great, but very expensive! This extender does that job for a whole lot less and is as sharp as without it! Good investment for any professional!

Get Closer

  • Excerpt: So far I've only had a couple opportunities to use this. I have a photo of a Bald Eagle that would not have been possible without it. Many professionals say extenders decrease photo quality. That may be true with some extenders but the picture quality with this one seems to be unaffected.

Worth it

fotoperceptions, B&H Photo
5 September 2015
  • Excerpt: Pluses: works very well on 70-200 f/2.8 II. Sharpness very similar, and you eventually might not notice it's "on". Minuses: yes, it's a stop loss and f/4 would be the widest you go (but usually close to 300 mm you'd want to shoot at f/8 if hand-held anyway).
  • Pros: Consistent Output, Durable, Strong Construction
  • Cons: Heavy, Poor in Low Light, Slow Focus

Great Product; Expensive

SteveR, Crutchfield
29 April 2015
  • Summary: This is a great product. The photos are sharp and focusing remains quick and accurate (assuming lens compatibility). However, the final cost of additional reach is quite expensive and perhaps not worth the hefty price tag to gain that extra zoom unless it's exactly what you need.
  • Pros: quick, sharp focus, small, portable
  • Cons: expensive for the total value that it brings
