Review of YS-01
Small and lightweight
The first time I saw YS-01 was in a catalog. The image I had was about one size larger, so my first impression when I held it in my hand was that it was smaller and lighter than I expected.
According to the catalog, the underwater weight is minus 10 grams. I have this strobe attached to the macro port, and even with batteries in it, I hardly noticed its weight underwater.
Since it is not heavy underwater (which is more important than the weight on land), I think this strobe is easy to use both on an arm and on a port.
I think DS-TTL is especially effective when doing macro work.
The light level control function in the YS-01 is very convenient because it allows the user to lower the flash amount without changing the DS-TTL setting.
This is very useful for me because I used to adjust the strobe flash output on the camera body (the strobe flash output compensation on the camera body cannot be adjusted once the housing is in place).
1.9 second recycle time
I have always felt that the price of a compact strobe is a longer recycle time, but the YS-01 has a recycle time of 1.9 seconds.
With the increase in normal ISO sensitivity with digital cameras, I rarely use a full flash at actual shooting sites, and with the 1.9 second recycle time, I can use a strobe with a generous flash output and still be able to shoot two frames per second with almost no stress in macro photography. The strobe can fire continuously without any stress when shooting macro. When you encounter a great scene, the time you have to wait for the strobe to charge is very long, isn't it?
I am glad to know that this is reduced.
Easy-to-use mode switch
Personally, I really like this large, finger-sensitive switch. The lightness of the switch feels so smooth that you can easily move it with a single finger.
If the strobe is located close to the housing, I can turn the power on and off with just my index finger without taking my hand off the grip. We don't use gloves, but with a switch that is large enough to be firmly caught on the finger, I am sure it would be easy to operate with gloves on.
Convenient target light
The YS-01 is equipped with an LED target light. This target light is very useful for checking the beam angle of the strobe.
It can also be used to illuminate the subject, and even left on during night dives, it does not consume much power since it is LED. I use it with a regular target light, and it is quite a useful light, especially when shooting at night or in slightly dark caves.
