At ISO 3200, at wide-angle, it can throw a lot of light. Sony claims about 45 feet -- "Strong flash up to 14m (ISO 3200/Wide end)" per an on-camera sticker -- and from what we've seen, they're not far off. Sure, as you boost the ISOs you'll gain more reach with any strobe unit, but the H3 can throw a lot of light at high ISOs, even in telephoto. We had no problems lighting up a framed print from 25 feet away at 380mm at ISO 3200, for a perfect exposure. At ISO 3200 at 38mm we also were able to light up an entire 50-foot wide front yard, including a very mature maple tree. While it's not the most exciting image we've ever shot, it does lend credence to the on-camera sticker's claim. Yes, you lose a good deal of resolution and there's some noise, particularly in the blocked-up shadow areas, but that Bionz engine handles it pretty well. For long-reach, low-light situations, the powerful strobe and/or image stabilization should help you nail must-have shots when other cameras will simply leave you in the dark. Of course, with any camera, it's the low ISOs that have the absolute best image quality, but there are times we'd rather bring home must-have shot at high ISOs, warts and all, than no shot at all. You'll want to lose the whole lenshood for wide-angle shots with strobe at all ISOs, or you'll get barrel shadows in the bottom of the frame. Also, there's no flash burst mode whatsoever.
