I've been shooting with my 90D for years but I've always stuck to natural light and now I have this last minute portrait session for a graduation next Saturday and I realized I'm totally screwed without a real flash. I was looking at the Speedlite 600EX II-RT but that price is insane so I was thinking maybe the Godox V860III?
My logic was that the lithium battery would be better than AAs but I'm worried about the TTL accuracy on the 90D specifically. I really need:
Should I just bite the bullet on the Canon brand or is Godox reliable enough for a paid gig? I only have about $300 to spend...
In my experience, the Godox TT685II-C TTL Flash and Yongnuo YN685 II TTL Flash are solid. Godox has better wireless range, but the Yongnuo recycle times are actually pretty fast for the money.
The Godox V860III-C for Canon is a solid choice for the 90D and easily outperforms the Canon brand flashes when you factor in the price to performance ratio. Regarding your concerns about TTL accuracy, Godox has refined their communication with the Canon E-TTL II system quite a bit over the last few years. I havent noticed any significant exposure drift when shooting portraits, even in changing light. The lithium-ion battery in the Godox V860III-C for Canon is far superior to AA setups. It provides around 480 full-power flashes and a 1.5-second recycle time that stays consistent throughout the charge. For a graduation session where you might be shooting rapidly to catch the right moment, this is a massive advantage. If you can stretch the budget slightly while staying under 300 dollars, the Godox V1-C Round Head Flash for Canon is another option. It offers a more circular, even light pattern which is generally more flattering for portraits. Both of these units support HSS up to 1/8000s, so shooting in midday sun wont be an issue. You can definitely rely on these for a paid gig. The build quality isnt quite as tank-like as the Canon Speedlite 600EX II-RT, but for the price of one Canon flash, you could basically buy two Godox units and have a backup. It makes more sense for a budget-conscious pro... basically just buy the Godox and dont look back.
