actually, @Reply #1 - good point! but honestly i think jumping straight to those super expensive models might be overkill for family stuff. i remember when i first got my 90D and felt so frustrated because my kids looked like white sheets in every photo... it was literally the worst! i ended up getting the Godox TT685II-C TTL Flash for Canon and it was a total game changer!! it uses AA batteries instead of the custom lithium pack, but i just use high-quality rechargeables and it lasts forever. plus it saves you a ton of cash. i also played around with the Yongnuo YN685 II Wireless TTL Speedlite for Canon which is even cheaper and feels so sturdy. honestly, i think the TTL mode on the Godox is way more reliable for beginners tho. its so amazing when you finally get that soft light! you'll never go back to that built-in flash again!

@Reply #2 - good point! i saw this earlier but just getting around to answering now. honestly the 90D works with basically everything since it still has that center pin, so dont worry about the compatibility issues you see on those cheaper rebel models. if you want to avoid that ghost look without spending a fortune, Godox is definitely the way to go over the native Canon stuff.

• Godox V350C Li-ion Battery Camera Flash is probably the best fit for your situation. it uses a rechargeable lithium battery so it recycles fast, and it is way smaller than the bulky pro flashes. if youre chasing kids around a birthday party, having a lighter setup is a lifesaver.
• Godox TT685II-C TTL Flash for Canon is a full-sized beast if you dont mind using AA batteries. it is super powerful and cheaper than the lithium versions. i usually tell people to grab some Panasonic Eneloop Pro AA Rechargeable Batteries so you arent constantly throwing away disposables.
• Yongnuo YN600EX-RT II Wireless Flash Speedlite for Canon is another solid choice if you want something that mimics the Canon interface. it is very reliable for the price, tho the build quality feels a bit more plastic than Godox gear. just make sure you use TTL mode at first so the camera does the work for you. the real trick is to point the flash head at the ceiling or a wall behind you instead of directly at the kids... it softens everything up so they dont look like deer in headlights. Godox gear is totally reliable once you get the hang of it, and way better value for a hobbyist.

The 90D still has the center sync pin, so Godox works fine. I was nervous about third-party gear too, but they are a decent option for the price.

• Godox V860III-C TTL Li-ion Flash for Canon has great battery life.
• Godox V1-C Round Head Flash for Canon is easier for soft light. Godox is pretty reliable nowadays... just make sure the firmware stays updated.
