Setup
The TTArtisan 23mm f1.4 can focus to 20cm, this isn't macro but you can get some nice close-up photos, excellent for flowers. To get even closer, I attached a 10mm extension tube and my TTArtisan 23mm f1.4 lens to my Panasonic GX9 Micro Four Thirds camera.
Technique
When I tried to focus with the lens focus ring, it didn't really work. The solution was to set the focus to the minimum focus setting on my lens 0.2 (20cm). To focus, I moved the whole camera forwards and back until the subject was in focus.
As you can see from the above, to get the image in focus I had to be very close to it. The usual 20cm was reduced to about 10mm (measuring from the camera the sensor to the subject). This is not a good working distance but for static subjects it's fine.
When using the 10mm extension tube I really didn't find using f1.4 made any sense. The depth of field was so thin. F4 perhaps but often I was using f5.6 or sometimes f8. It depends on the subject, the lighting, the background. The fun of photography is often in the experimentation!

The TTArtisan 23mm f1.4 is a very reasonably priced manual focus lens. Click here for more on this lens. The 23mm focal length is not really the best (a longer focal length would be better) for close-up or macro but I thought this was an interesting experiment.
The 10mm extension tube I have is the Meke MK-PAF3A. But any extension tube will do. They are easy to find on Amazon, eBay, etc, for a reasonable price.
I also have a 16mm extension tube. Using the 10mm, I had to get very close to the subject to have it in focus. For this particular 23mm lens, I found the 10mm extension tube was best. But of course you can experiment and it depends on your lens focal length which combination of extension tube will work for you. Generally, for close-up or macro work, it's better to have longer than a 23mm lens.

As you can see from the above, to get the image in focus I had to be very close to it. The usual 20cm was reduced to about 10mm (measuring from the camera the sensor to the subject). This is not a good working distance but for static subjects it's fine.
Even with the lens set to f5.6, because the lens is so close to the subject, it can be difficult to get the subject in focus. In the above picture, on the screen you'll see some blue, that is the focus-peaking, it helps a lot. Just wait until the subject edges have a little blue (or whatever colour you are using) and press the shutter button!
Look carefully at the two pictures above. Getting that critical focus on the subject is not easy. I took these photos handheld but if you use a tripod this will be easier.
Aperture
On Youtube and the web in general, everyone goes on about aperture, how the larger it is (the lower the f number), the better. The lens I'm using starts at f1.4, that's fantastic for portrait or similar photos. For close-up or macro, a higher f number makes more sense. In the example above I used f5.6 and yet very little of the photo was in focus because I had to get so close and the subject was very small. Experiment, perhaps f8 or even higher would be better. It depends on the look you are trying to get. Here are a few example photos taken with the TTArtisan 23mm f1.4 and 10mm extension tube, at different apertures.

Cost
Are you interested in macro photography but don't know if you want to spend several hundred on a specialised lens? This combination of the TTArtisan 23mm f1.4 and 10mm extension tube is a very cheap option. Brand new the lens is less than USD 100 and extension tubes are perhaps about USD 20. Technically it isn't true macro but you are getting close and you can get some nice shots. I've used this 23mm lens because I have it in my collection. Maybe you have a different lens, that's fine too. There are so many excellent manual focus lenses at the around 100 dollar mark.
Alternatives
As an alternative to extension tubes, try a converter. In a previous article I wrote about the Olympus MCON-P02 Converter. Fit it to the front of the Olympus 45mm f1.8 lens and you have a great little macro solution. It has an advantage over extension tubes, with the converter you can easily remove it and put it back on. Perhaps you want a macro photo and then see something else that is far away, with an extension tube it's a pain, with the converter it is a little quicker to remove. The negative with the converter is that it fits only specific lenses and it is nearly 100 dollars.
A more obvious solution would be to buy a true macro lens. There's the Panasonic 30mm f2.8 macro and Olympus 30mm f3.5 macro. I've not used either of those but all the reviews I've seen boil down to them being excellent choices. Both those are around the USD 300 mark so pretty good value. If you can afford it though, I would recommend the Olympus 60mm f2.8 macro. I own this lens and I love it! Here's an article I wrote on the Olympus 60mm f2.8 macro. It is around the USD 500 mark but truly excellent!
True macro lenses have some big advantages. They were designed for macro so the image quality is optimised for that kind of photography. You will get true 1:1 macro, which means the subject will appear at the same size in your image. Also, a true macro lens makes it easy to switch between near and far. What I mean is, if you are photographing a flower close up, then you see a bird in the corner of your eye, with the Olympus 60mm f2.8 macro you can quickly change and take photo of the bird. With a lens and extension tubes you'd have to take the lens and extension tubes off and put the lens back on... the bird would've gone in that time.
There's also the Laowa 50mm f2.8 2X Ultra Macro. I've no experience of it but it's just USD 400 and it provides 2:1, meaning the image is twice the size of 1:1. Maybe an option if you need to get closer. Although you could add extension tubes to the Olympus 60mm lens to achieve this. Perhaps the ultimate solution would be the new OM Pro 90mm f3.5 macro lens. But that is around the USD 1500 mark!
Conclusion
The TTArtisan 23mm f1.4 lens on its own is good for close up photos with the native 20cm minimum focussing distance. When fitted with a 10mm extension tube the minimum focussing distance is much less and it's possible to get some excellent macro (or at least macro-like) photographs. This combination works well.
The downside is that you have to get very close to the subject. If you want to photograph insects, I'd say this combination won't work well. With the very short focussing distance you might get some shadow of the lens in your photo, that's also not good for macro as you need all the light you can get. Perhaps a longer focal length would be better... but despite this, I enjoyed using the TTArtisan 23mm and 10mm extension tube, I found it useable and fun!
