Yes, the AF mechanism is a bit slow, noisy, and fragile. Yes, the vignetting is pretty high and the corners are soft wide open. Yes, the Canon hood is an extra expense and is worthless. It is not an "L" lens, very far from it.

But, none of that matters. This is the closest thing to a universal lens in the lineup. It is the smallest and lightest lens which makes carrying it very easy. It is one of the least expensive lenses in the lineup. The 32mm f/1.4 and the 22mm f/2.0 are the only two lenses I would consider using indoors in low light. However, the 22mm focal length means you are much less likely to literally get backed into a corner than with the 32mm. The minimum focus distance is only 15cm. Even wide open, the center is quite sharp.

The image quality is good enough and it is the only lens in the lineup that I know I could take anywhere in the world, at any time, and get a very good photo. Some of the other lenses are nice too, but they are either too dim and/or the focal lengths would put my back against a wall.

I'm curious. Is the 22mm f2 lens really slow for auto focus and noisy? Is the 22mm lens slower in focus compared to the 15-45mm kit zoom lens?

Yes

Is the 22mm lens noisy enough for the focusing sound to be recorded in video either with the internal mic

Yes

or an external mic?

Maybe

I'm considering getting the 22mm lens so that's why I'm interested. Thanks!

The 22mm is not awful in any of these regards, but it is not as fast or quiet as the other EF-M lenses.

Another question on the 22mm f2 lens please. What is the closest focusing distance of this lens? I'm hoping to use it as a ghetto macro lens, lol.

It works quite well for that purpose.

As MyM3 stated, the minimum focus distance is 150mm, or 6 inches. Anytime you see minimum focus distance (MFD) it is measured from the image sensor plane. The EF-M 22mm lens is 24mm long. The mounting flange of all M series cameras is 18mm from the image sensor. The front of the EF-M 22mm is 42mm from the image sensor (18mm + 24mm = 42mm). So, the closest you can get an object to the front of the lens is 150mm - 42mm = 108mm. For those living in the colonies, that is 4.25 inches from the front of the lens.

I don't know of any Canon lenses that focus any closer that are not dedicated macro lenses.

Wow! So the 22mm lens can focus on an object 4.25 inches away? That's quite close! Might you know what that would be roughly equivalent to in terms of ratio? I seem to recall when I had my Nikon and Hasselblad macro lenses, there were ratios such as 1:1 for 100% life size, 1:2 for 50%, etc. I'm guessing those ratio numbers are only used for lenses designated as macro, not "regular" lenses?
