How about Canon 70d kit? 18- 135mm lens enough? Or 18-200mm? I hope professionals can give me advice.

From the point of view of photography, Canon 600D 700D is enough, of course, 700D is better, the pixel is higher, the continuous shooting is faster, and the focusing system and maneuverability are improved!

70D 18- 135MM is enough! If you want to travel all over the world, of course, 18-200MM is better! However, from the perspective of future upgrade, 18- 135MM is more reasonable, and 70-200MM and 100-400MM can be purchased in the future.

In fact, Canon 700D 18- 135MM is very good and cost-effective. Compared with 70D, not much difference!

As for the problem of blur in place, not only a large aperture lens is needed, but also the distance between the photographer, the subject and the background! The closer the photographer is to the subject, the farther the subject is from the background, and the more obvious the blur is.
