Review on 📸 Enhance Your Sony DSLR Experience with the Sigma EF-610 DG ST Electronic Flash by Genene Locson

EF-610 DG ST works very well with Sigma DP2 Merrill with the latest firmware update. For me, this niche camera with great image quality was a stop on my photographic journey. In practice, I can only afford one camera at a time. I once suffered from GAS and had an SLR with lots of lenses and accessories. This flash has limitations that I didn't realize until I read the manual. There are only two manual settings, FULL and 1/16. In other words, the button on the back of the flash gives you three options: TTL, MH (FULL) and ML (1/16). Don't get confused: although this flash comes with a stand, it has NO additional features. Note that you can adjust flash exposure compensation by up to 2 stops plus or minus in TTL mode. After two stops, the TTL flash function does not work properly. To me, this is more of an observation about the camera firmware than an issue I'm having. Final comment: the EF-140's small flash is very useful for non-reflective shots as it's very powerful for its size and can be all you really need it to be. But its performance isn't enough to reflect (with homemade light modifiers) in all but the smallest rooms, the widest apertures, and higher ISOs (400).
