Excellent Optics - However, most misunderstand how to use an extender!

The Extender EF 1.4x, the 3rd generation has excellent optics and produces impressive images (So does its 2x sibling). The purpose for using this extender to enlarge the subject matter in the image frame. Not to reach long distances. Atmospheric interference means any haziness, or heat haze will only be magnified. This extender was designed for L lenses. It works superbly with the prime lenses. I have used it with the 300mm f/2.8 ver II, 500mm f/2.8 ver II as well as the 600mm f/4 ver II. In addition, I have used this extender with the EF 100-400mm ver II. The images this combo produces is amazing considering it is not a prime lens. If your goal is to extend your reach so you can take pictures of distant subjects and expect a clear and sharp image, you will be disappointed. Even a prime lens with the extended reach will have difficulty producing a clear image due to atmospheric conditions. However, if you are taking pictures of subjects such as birds, or aircraft that fit 1/2 of the frame and wish to have images that fill 3/4 or more of a frame at distances that are not effected by atmospheric conditions, then you will amazed by the results this combination provides. Note: on a zoom lens such as the 100-400mm ver II, your f stop will become f/8 and therefore you will only be able to use a small portion of the autofocus points and in lower models perhaps manual focus will be your only choice. This is where a mirrorless camera is the perfect solution as it will allow for use of all autofocus points. Also, because of the additional reach, you will need to increase your shutter speed and expect slower autofocus acquisition in low light. This is an excellent addition to ones photography tools, but needs to be used in appropriate conditions.

extender 1.4x lll not sharp?

It appears to not be sharp at least at 4.0, 4.5, 5.0 and low apertures. Not surprised as I have had a few 1.4x extenders that have also proven to not be sharp. Very annoying...It may get sent back after I run a few more tests.

Extender EF 1.4x III limits my options.

When used with the EOS Rebel T2i body, the autofocus won't function. Your only choice is manual focus. It also will not fit onto Zoom Lens EF 75-300mm 1:4-5.6 III. But it works wonderfully with Zoom Lens EF 100-400mm 1:4.5-5.6 L IS II USM.

The distortion at long range is more than I thought it would be.

I get very sharp images!

I resisted buying one because of not so hot reviews. Then I learned that pros use them and attribute problems to user error. So, I bought one. I use it mainly for shooting birds with a 5D IV and 100-400 IS II. I have also used it with a 77D. Bear in mind the longer focal length will require a steadier hold and/or higher shutter speed. Autofocus can struggle in low contrast situations. My results improved when I practiced steady holds. The photo below was shot at f/11 & 1/500 handheld. It's also been cropped at least 80%.
