Sebastian...I think I understand what you are intending to ask. If my answer is not to the question you intended to ask, please let me know, and we will figure it out.

A general rule for a long time has been to use a shutter speed no longer than 1 divided by the focal length of your lens. For a 50mm lens, the slowest shutter speed would be 1/50 second. This is a general rule, and is considered valid for all focal lengths.

Of course, some people can hold a camera more steadily than others, so some may meed to choose a faster speed, and some may be able to use longer exposures. And now that lenses and some camera bodies have image stabilization, it is very often to use longer exposures with equipment having that capability.

One caution...this is a general guideline, not a hard and fast rule. Some may try to complicate it in all sorts of ways, including your sensor size and all sorts of things. Ignore all that. It is a simple guideline based on the physical relationship between the lens and the sensor.

Enjoy shooting, and please stay safe.

If your jpg processing doesn't measure up, shoot RAW. JPG is not for everyone. When I say raw is not worth the effort, It should be understood I'm speaking for myself, not everyone. I've noted several times that for some, like billnikon, shooting RAW may be the only way to shoot. When I speak of raw zealots, I'm not necessarily talking about you just because you always shoot in raw. A raw zealot is one who constantly pontificates that RAW is for everyone, and exaggerates to the extreme the benefits of raw. There are a small handful of those, and when they show up, I enjoy the banter. BTW, I often shoot in RAW and never to my knowledge insinuated that no one should ever shoot in raw. It's benefits for most, imo, is the last thing most need.
