Question: What is the difference between two photos? Why?

Hint: I used a 16mm lens.

Answer:

Can you see that the flash is concentrated in a small circle in photo 1?

Well… you know that when you zoom, or change lenses, the flash changes its zoom, right?  But the widest zoom is 24mm, and I shot at 16mm. That is the top picture. The zoom circle is too small for the picture.

In the bottom picture, I pulled out the plastic “wide angle adapter”, the transparent plastic square you can pull out to cover the front (not the white sheet). This is not a softener; it is merely the 14mm adapter”. The zoom device for wider than 24mm. It makes the beam wider, see picture 2.

That’s all: when you zoom wider than 24mm, pull out the wide angle adapter.
