Rated 3 out of 5

works well with APS-C, bad vignetting @ wide angel

flash works well on aps-c bodies, thanks to the small form-factor, however at focal lengths of 20mm or lower, you can see a lot of vingetting where the flash just doesn't cover the whole sensor

Sony 28RM

I have had this for a few weeks and have used as a bounce flash indoors and direct (fill) flash outdoors. It is powerful for it s size and produces nice results. It slips onto my A7C hot shoe without much effort however it is a very tight fit on my A7IV which is strange. I have read that it is a common issue on both the A1 and A7IV. It works fine once pushed home but be careful not to break it!

Great little flasgun

Having bought 3rd party flashguns in the past I decided to try a Sony flash with my Rx10 IV. The flash is very lightweight, portable and quite powerful for its size. I have it works very well with the rx10 and exposure seems far better than other flashguns I have used. The only disappointment is the head doesn't swivel.
