BUT: about that difference with the shutter speed... I noticed and wondered why that happened. The camera was on a tripod on a full sunny day. These pics were 3 min apart because it took me some time to get the zoom lens to exactly 32mm. But I switched back and forth over 15 min with a couple different angles and every shot with the 32mm the camera chose 1/1000, and every shot with the 18-150 the camera chose 1/2000.

These are the two possibilities I think:

1) Some slight change in cloudiness happened just as I changed lenses (several times) which was enough to cause the camera to alter shutter speed

2) These lenses don't actually let in the same amount of light at their stated settings.

Hi,

have you checked wether the focus point is exactly on the same spot?

You should add or change the steps!

a) Use M-Mode in order to control the exposure!

b) Use Manual Focus to always focus on the same point!

(c) Always use the EF-M 18-150mm first for framing, focusing and taking the first shot. Than switch to the EF-M 32mm.)

Additionally, mark the spot where the EF-M18-150mm is zoomed in to 32mm.

I gonna try to do the same for the same lenses and maybe other lenses Cool Idea!
