## Description

Canon 1.4x EF Extender III (Teleconverter) WHITE COLOR

Review: Use it with my Canon EF 100-400mm f/4.5-5.6L is II USM. It is the sharpest zoom on the market, and the loss with this converter is minimal. Yes you do lose one stop of light, but the IS of that lens is so good that it does not cause issues.
Review: As an amateur photographer who lives in Alaska and loves to shoot wildlife I was wanting this badly and finally grabbed it right before I went on a bear viewing trip. Design: As with everything with Canon, these are really well designed and work perfectly. They even updated the color on these to help them match better with the newer version of the 70-200 and the 100-400, so that is a nice bonus. It is light but still has some good weight to it so you can feel the quality construction. As for the use of this, it works perfectly with the EF lens series. I can also verify that it works with the RF-EF adapter on the mirrorless cameras. REMEMBER THAT THIS WILL MOVE EVERYTHING UP ONE STOP ON THE CAMERA and EFFECTS THE AUTOFOCUS POINTS. MICRO-ADJUST THE CAMERA TO ENSURE BEST FOCUS or, like me, your photos will just seem to be slightly soft on focus Cost: I purchased it for $340, currently $429 Overall: I am a Canon equipment user and this is just another in a long line of great products Positives: ++Cost (but I got it almost 25% off) ++Design Negatives: --Autofocus effects --F-Stop adjustment Would I recommend: Absolutely/Borderline. Absolutely I would buy it again, borderline if you are not sure what to do with the other settings on your camera. Photos attached with the adapter on

### ⭐⭐ Review
*by D***I on 28 October 2019*

This product is fantastic when it works. It doesn’t fit non-L Canon telephoto rear EF mounts. Works best with L series telephoto primes. Advised to check the list of compatible lenses before buying. When used with Canon crop sensors like 80d one gets 2.2x zoom with 24 mp resolution. That’s great at 300 mm focal length for birds or wildlife. Buy it if you can put it to good use.
