Should Canon use 17-40 or 18- 135 when shooting portraits outdoors?

From the quality of the photos taken, the dog head of 18- 135 is really not as good as the cow head of Canon 17-40. However, it doesn't mean that the photos taken by 18- 135 are terrible, which can completely meet the needs of family, office, news propaganda and other occasions where the photo quality is not very high.

18- 135 is not only cheap, but more importantly, its focal length is full of the most commonly used people, and it is also known as a mirror for walking on earth. As a non-full-frame machine user, it should be your first choice to equip one 18- 135 (or 18-200).

First, only by skillfully using 18- 135 can you really know what kind of lens you need; Second, even if you have a group of tauren, it is very appropriate to have a 18- 135 (or 18-200) when you want to travel or it is inconvenient to bring a long gun and a short gun. A camera is enough, which is convenient and practical.

There are many outdoor photographers, so it is best to match 18- 135 first. If you are afraid of hanging 18- 135, and this dog has no face, then you can only go to Canon 17-40 and other tauren. You can't have it both ways!
