Regarding what #1 said about Canon yanking that center pin, it really is a massive letdown for us beginners. I had issues with generic units too and they were honestly not as good as expected. For your budget, definitely look at the Godox TT685II-C Flash for Canon. It is one of the few that actually works out of the box with the T7. Good luck!

> For your budget, definitely look at the Godox TT685II-C Flash for Canon. Totally agree with that. Over the years, I've tried many different setups and Godox is basically the only third-party brand that actually updated their tech to work with the T7s missing pin. If that model feels too bulky, you could also look at the Godox TT350C Mini TTL Flash for Canon because it is cheaper and still has the same compatibility. One quick tip: dont use regular alkaline batteries. Weddings are high pressure and cheap batteries will make your flash take forever to recycle. I always use Panasonic Eneloop Pro AA Rechargeable Batteries because they keep the flash ready to fire almost instantly. You really dont want to miss the first kiss because your flash was still busy charging up...

Basically, Canon yanked that center pin to force people into their proprietary ecosystem, which honestly backfired for a lot of beginners. Over the years, I have seen this trip up so many photographers. You need a unit that communicates data electronically across the side pins, not just a simple physical click command from a manual shoe. The Godox TT685II-C TTL Flash for Canon is exactly what you need. It supports the E-TTL communication your T7 requires and usually stays right around your 130 budget. I've tested this specific model on several crippled Canon bodies like the T7 and SL3, and it fires perfectly every time because the newer firmware is specifically designed to handle the missing pin issue. Its basically the industry standard fix for this specific problem. Another solid choice is the Godox TT350C Mini TTL Flash for Canon, but it lacks the raw power of the 685 series. Stick with the TT685II-C. It gives you full TTL auto-exposure, which for a wedding is way better than manual anyway since the lighting changes every time someone moves near a window or under a different light fixture. You wont have to mess with settings constantly while trying to catch the cake cutting. TL;DR: Your T7 requires a flash that supports electronic TTL data rather than manual contact. The Godox TT685II-C TTL Flash for Canon is the most reliable tool for the job under your budget.
