28mm, f1.4 @ 1/10, ISO 1600 and a bit of light on the wall.
There’s only one thing to do: Get a lowlight lens. Mine has a max aperture of f1.4. Yes, there are some lenses that are just a bit faster (f1.2) but I like the fixed 28mm focal length of this prime lens. This lens goes to f16, but that’s not why you buy it. There are many less expensive ways to get to f16, but this one is all about 1.4. The lowlight bug shares many things with the macro bug so if you’re into getting pictures of small things, you will know what I mean. Shooting hand-held as long as possible is a cheap, yet thrilling experience. I’ve currently reached a new low of 1/10th/second and have not switched to decafe.
If f.14 is beyond where your lens opens, just dial in whatever max aperture your lens provides, crank up the ISO (I like 1600) and see what shutter speed pops up.You should know how long you can hold the camera without blurring the image. When/if you’re not certain, keep extending the time until the image is not sharp in any part.
Since exploring lowlight photography is available at a camera near you, it certainly won’t hurt to try it. Then, on a dark night when you least expect it, that little lowlight bug just might think of you as dinner. Once you’ve tried lowlight photos, let me know how it works (or not) for you.
