Excerpt: This is a very nice camera. I love its weight and compact size in comparison to my 5D. Convenient carry camera. Picture quality is excellent. It has a good feature set given its reduced size covering most photograph situations other then non flash low lighting siutations. However, its short battery life caught me by surprise and is a disappointment. Battery life is noticably worse than with other Canon EOS cameras.
Pros: Easy To Use, Fast / Accurate Auto-Focus, Fast Shutter Speed, Good Image Quality, Good Image Stabilization, Large Clear LCD
Excerpt: I bought this lens to replace the 18-55 mm kit lens that I damaged on a previous trip. This lens autofocuses very quickly and is extremely quiet. I initially wasn't sure the autofocus was working because no sound was being made at all. The STM is great! The glass isn't the fastest, but the 18 mm-end is great for landscapes, and it's nice to have the 55 mm-end for closer work. Given the price, it's a nice lens to have in one's bag.
Pros: Consistent Output, Fast / accurate auto-focus
Conclusion: The 18-55 mm IS STM lens is great for video.It smoothly & noiselessly glides from subject to subject. For stills the focus is lightning fast. Super sharp lens. At closer distances at 18mm, barrel distortion is very pronounced. I have not noticed it at normal distances. The plastic bayonet mount contributes to its light weight; but I prefer metal. The electronic manual focus takes getting used to.
Excerpt: I have a 70D (previously a 60D) and my wife would never use my camera because she found it too large and needlessly complex (I have single point autofocus, AI Servo, back button focusing, and manual modes enabled all the time). She wanted something smaller that wouldn't weigh a lot, be large, or too hard to use but still offered superb image quality and the ability to use additional lenses.
Summary: This lens is basically on point with the standard 18-55 kit lens that comes with other Canon lenses. It is decent for the cost however it does not provide anything extraordinary for this type of lens. Although the minimum aperture is unimpressive, the image stabilization really does help in a pinch. I have found that I use the 22mm pancake lens much more often, due to its impressive optics and standard field of view.
Excerpt: I got this lens because of the STM feature. Tried it on my 70D and it works great outdoors. Nice sharpness and you can't hear the lens focusing - it's like magic. Not too good in low light however. But my L lens is not good in low light either and you can hear the focusing (a light buzzing sound). I give it 4 stars becuase the mount is made of plastic. I also ordered the 40mm STM and that one seems to be more solid with a good weight since the mount is made of metal.
Summary: This is my back up camera kit so it wont get a hard workout. Very satisfied with images but they are not in L-series class, still with a wee bit of post they are quite good. The build could be a bit better so not a candidate for long term use in a demanding environment. That said it is a good value for the money.
