The notion of using a camera in low-light depends on several factors.
With a 35mm film camera or "full frame" camera, the photographer who practices good hand-holding techniques (so there's a condition) can probably hold a camera steady enough to take a shot at a shutter speed of 1/
focal-length with reasonable success. That means if you had a full-frame camera (your camera is not full-frame) then a 200mm focal length might be hand-held at shutter speeds of 1/200th sec or faster. A 50mm lens would require 1/50th sec or faster.
Your camera isn't a full-frame camera. It has a crop-factor of 1.5x. So the formula would be adjusted 1/(
focal-length x
crop-factor) or 1/(
focal-length x 1.5)
In other words, if using a 50mm lens, it becomes 1/75 sec exposure time. If the shutter speed is 1/75th sec or faster then you can probably successfully hold the camera without a tripod
if you practice good hand-holding techniques.
Some lenses have built-in image stabilization. The stabilization improves your odds of success and is usually based in stops of shutter speed... most image stabilization (depending on who makes the lens they'll call this "IS" or "VR" or "OS" or maybe something else) is good for at least 1-2 stops. Some better lenses improve it down to 3 or even 4 stops. Having image-stabilization isn't a guarantee of success... but it dramatically tilts the odds in your favor. You'll still occasionally get the shot where the stabilization didn't save you from camera shake.
Good hand-holding technique means things like:
- legs in a wide-stance (think "baseball stance") with your body weight centered over your legs (you aren't leaning)
- arms are supporting the camera from below with elbows tucked in to your stomach -- don't have your elbows out sideways)
- rest the camera on something if you can ... or lean on something solid if you can (a post, a fence, a tree, a wall, etc.)
If your muscles are working to keep you steady then your camera is likely to shake. But if you put your center of gravity over your legs then you're basically using your bones to hold yourself up -- not your muscles. If your elbows are tucked in supporting the camera from below then they "brace" the camera to your body core ... rather than supporting the camera with your arms (if your elbows are not tucked in).c You can find videos that explain these techniques.
Aside from those techniques, and the help you get from in-camera or in-lens image stabilization systems... put the camera on something that doesn't move (which could be a tripod ... or it could be anything you can find int the environment.)
Lower focal ratio lenses (e.g. the 50mm f/1.8 ... or 50mm f/1.4 are examples of low focal ratios) will allow the camera to collect considerably more light... but at the trade off of a shallower depth of field. For some subjects it might be too shallow.
