I recently bought a SLR, and I would like to ask what kind of lens should an expert use?

1. 17-40, it can be hung up when used on the 60d. The advantage is that it is cheap and will continue to be available in the future. However, the red circle lens has mixed reviews. If used well, the effect is no less than that of the junior camera. Meta lens!

2. 16-35, no need to introduce more! The performance is nothing to say,

3. 18-200 dog head, the effect is average (compared to the red circle), light, practical, convenient for various occasions, if you don’t have high requirements for image quality, then It's up.

4. 24-70 is generally not recommended for novices.

5. 35L, I think it is almost a year old. It is a humanistic lens. The problem is that novices need to find a fixed focus point. ,,,,,hehe, if I use it directly, this lens is enough for you if there are no special requirements.
