Reddit mentions of YONGNUO RF-603C-II-C3 Wireless Remote Flash Trigger Kit for Canon 1D 5D 7D 10D 20D 30D 40D 50D

If you have a tripod, you could always use something similar to this. I got one so I could take pictures of my entire family, instead of just the wife and kids. It works wonders!

Im going to apologize in advance for links, im on mobile.

I have this yongnuo flash https://www.amazon.com/dp/B00PGTOX26/ref=cm_sw_r_cp_apa_i_cDbdBbQERE1DE

And this trigger https://www.amazon.com/dp/B00JVEXRE2/ref=cm_sw_r_cp_apa_i_YEbdBb9TKN17R

They both work extremely well and reliably. I'm not super well versed in off camera flash but you could easily keep the yongnuo on camera and optically trigger the canon or remote trigger the yongnuo to have both flashes off camera as you described with the 2 products I linked. Good luck!

I started with Yongnuo and half my kit still consists of it.

You go from triggers, to flash, to a trigger made to work seamlessly with their flash.

Highly Recommend espically for a first/beginner set up.

Also went through this decision process just this past weekend. Everybody goes for Godox, but me being the different guy that I am decided to go with Cactus. I bought two units (they are dual function; they serve as transmitter or receiver so you just buy these. This particular one is the HSS version. They have a cheaper $46 non HSS one) and will work with practically any flash including the Olympus FL-600R I already have. (Yes I know I can use the optical slave feature, but I hate optical slaving.) I had to go to Cactus's website to order the trigger cable, which will allow me to use this set as a remote trigger when mounted on a camera. (I have some notion of using it as a dual-camera setup one day, for action photography, to get two shots at the same time etc.)

Another route is Yongnuo. This is the dirt-cheap option and would get you well under your $200 budget. Yes it's for Nikon or Canon but it will trigger your flash by way of the universal pin, you would just have to be in 100% manual mode no TTL. You would then order Yongnuo speedlites (less than $80) which are again all manual but would work with the transmitter without an additional transceiver. (so you could pop a half dozen of these boogers at the same time if you wanted.) I have myself used this setup with my Olympus M10 as a test once, and it worked - again, I just had to dial my flash settings in manually.

Canon's optical trigger system does flash on camera but I believe it is timed to not actually light the picture. If you want radios, Yongnuo 603 system is simple enough and can even be used as a remote shutter release for the camera when not using it for the flash. https://www.amazon.com/YONGNUO-RF-603C-II-C3-Wireless-Remote-Trigger/dp/B00JVEXRE2/ref=sr_1_3?ie=UTF8&qid=1466616933&sr=8-3&keywords=yongnuo+trigger

You'd have to do the research to find what's compatible with your camera, but what you're looking for is in the realm of these, which I've been using for the past few years: https://www.amazon.com/YONGNUO-RF-603C-II-C3-Wireless-Remote-Trigger/dp/B00JVEXRE2

So perhaps something like this? https://www.amazon.com/Trigger-Altura-Photo-Wireless-Shutter/dp/B00CMF9HFA/ref=sr_1_5?keywords=wireless+flash+trigger+canon+t3i&qid=1574649407&s=electronics&sr=1-5

Hope this was helpful, good luck!

These are super handy for a remote flash trigger

They also function as a a remote shutter. I have 4 of them now and use them quite a bit.

In case you want to give them a shot, they're cheap and cost effective.
