Field test Yongnuo YN-E3-RT in Music Room of Mission Inn Hotel

Yongnuo's YN-3E-RT transmitter with built-in infrared autofocus assist beam was instrumental in this picture. ISO 400 1/30 f4 with 17mm lens Canon 5DMark2 using 2 600-EX-RT Speedlites placed about 10 o'clock and 3 o'clock set to 1/8th power.

I got my hands on Yongnuo’s YN-E3-RT at the end of last year.

I used it at several ‘event’ type settings and so far I have to say I am pleased with the results.

My first impression of the Yongnuo YN-E3-RT was that it was worth the risk, now that I’ve used it on actual jobs with confidence, I have to say I am very happy with my purchase.

Keep in mind the build isn’t as good as the OEM Canon version.

I suppose that’s why you’re paying a lot less–at least $174 less!

Canon’s ST-E3-RT is $264 and Yongnuo’s YN E3-RT is $90.

Here’s a recent image I made using the Yongnuo’s YN E3-RT transmitter.

Here's a view of the Music Room where this is the only source of daylight.

I was in the Music Room of the Mission Inn Hotel and Spa.

That room is dark even during the day because the lone window is at the back of the room and it doesn’t light the dance floor.

The other end of the Music Room of the Mission Inn Hotel & Spa. Pretty, great atmosphere but when it comes to lighting, it is like a dungeon. If you look carefully you can see my 2 Speedlites on lightstands

If you photograph enough events like this where there is action on a dance floor, you will realize even if you light the area, either your camera or you need to manually focus on your subjects to make a picture.

Since I don’t run out and buy the latest greatest gear I learn to adapt to the limitations of my equipment.

Presently low light autofocus is something I have to deal with since I shoot with a Canon 5DMark2.

My old eyes are making it harder to focus in low light as well.

So I am very thankful for the built-in autofocus beam of Yongnuo’s YN E3-RT transmitter.

While it is true most of my low light images will have subjects in the middle because of the grid that is emitted, it is still better than not having my subjects in focus.

On the very dark dance floor using 2 Canon 600EX-RT Speedlites and Yongnuo YNE3-RT transmitter, I was able to get a good area in focus. ISO 400. Dragging the shutter at 1/10sec f5.6 with 17mm lens. Canon 5DMark2
