Something to note RE shutter speeds.
As a general rule, around 1/125 can be handheld.
If you’re using a zoom lens keep it twice the focal length, i.e. if you’re zoomed all the way in using a 200mm lens, then the shutter speed should be around 1/400.
If you have vibration reduction on your lens then go 1.5x the focal length.
On most cameras you can increase the ISO setting to around 400 without adding too much noise, so only go higher if you really must.
If you’re not really interested in learning how to use and get the most out of your camera then just go for the preset auto modes.
