Is it fixed focus with 50mm or 18-70mm?

If you shoot for a long time, you will find it boring to blur or something.

Taking pictures, blurring is not as good as getting a black background board behind; When shooting people, light and shadow are more important, and people are highlighted by light.

So, let's say fuzzy:

1, large aperture. The larger the aperture, the stronger the blur ability;

2. telephoto end. The longer the focal length, the stronger the blur ability;

3. Distance from the subject. The closer the distance, the stronger the fuzzy ability.

Although I personally think that 18-55 is enough, for you, if you pay more attention to blurring, it is still 18- 105.

In addition, the portrait focal length recommended by new york photography course is 85- 135, which makes people's nose not easy to look big or flat. APS frame changes the viewing angle rather than the focal length, so maybe 18- 105 will suit you better.

Of course, each shot has its own shooting method, and wide-angle leg pulling is also very interesting.

So personally, maybe 18- 105 is better for you.
