Godox iT20 Reviews
Great little flash
By Mark
Rated 5 out of 5
Date: 2026-07-17
Have only taken it out for a spin once now, but already very satisfied with the purchase. The small size makes it easy for travel or to stick in a bag just in case. Nice stripped down build and clean edges allowed me to tape some diffusing material over the bulb for some macro shots. Price point was also good.
Not something you would want at a rock concert but . . .

If you are a macro shooter, like myself, or just someone who wants a handy, light weight little flash that gets the job done at an average snapshot distance indoors, this is a good buy. It's disposable and having used lithium batteries over the years, if the rechargeable battery in this flash, a LiPo is anything like its predecessors, then it should last long enough to make it worth the money. Google AI shows 2-3 years average use or 300-500 charge cycles, so for the price, that's pretty good I think. All in all, I am very pleased with it.

What is the maximum focal length this flash can cover? Thanks
The Godox iT20 S TTL Mini Flash for Sony (Black) does not have a zoom function, and Godox does not list the focal length it works with. It is a very low-power flash, and I would not use it for a distance more than 7-10 feet at the most with a lens no longer than an 85mm. And a lens that is no wider than a 50mm.
