EF-610 DG ST Flash
Perfect Lighting, Full Automatic
The newest addition to the Sigma line of flashes is the most powerful one yet, now offering a Guide number of 61 which translates into 61/m (200/ft) and designed to work with the latest TTL auto exposure systems of all the most popular digital and film SLR cameras. It features TTL automatic flash exposure control for easy operation. The auto zoom function automatically sets the optimum illumination angle in accordance with the lens’ focal length in a range from 24mm to 105mm. When the built-in Wide Panel is used, the flash can cover the angle of 17mm. For bounce flash, the flashgun head can be tilted up and to the right by 90 degrees, or to the left 180 degrees. It can also be tilted down by 7 degrees allowing ease of use for close-up photography. In addition to automatic mode, the flashgun also features a manual flash mode, making it possible to set the flash power to full or 1/16. When the flashgun is fully charged, a confirmation “ready” light will be emitted and the flash exposure level can be checked through the camera’s viewfinder. Also includes Auto Power-Off function to help save battery power.
Dimensions (W X H X D): 77mm×139mm×117mm / 3.0in. X 5.5in. X 4.6 in.
Weight: 320g (11.3oz.) (without batteries)

Very important issue with this flash: There is a built in diffuser that if you pull it out turns off the TTL Feature. The flash becomes manual. I found that out the hard way when I let my wife take some professional photos for me. The diffuser must be pushed all the way back where it must hit a switch. You can't use it with the flash set on TTL.
Edit Oct 16, 2014
Initially I gave this flash 5 stars but the fact that it doesn't work well after a few months of light use I wouldn't recommend these anymore. The TTL is nice but you out grow it quickly and the high or low options just aren't very practical for most shots.Read more ›
1. It takes literally minutes to initially charge, even with fresh batteries. This is extremely annoying if I just want to grab the camera and take a quick shot.
2. The interface is absolutely atrocious. Each mode has a use but they're unintuitive and the button interface is clunky. I don't expect a touch screen but it'd be nice if we'd progress a bit from 1980s watch designs.
Works perfectly on my K-7. Get some gels and get flashing!
* It only has three stopping positions when you tilt it upwards, and the first is maybe 80 degrees; the last is a bit backward.
* The battery compartment door is very poorly designed; it comes off easily and is tricky to replace (it isn't designed to purposely come off, it just does).
* There are only three modes in which it can operate: ETTL II, full power, or 1/16 power
If you're only interested in lots of light straight forward, or angled nearly straight up for bounce, in ETTL II mode, then this is definitely more cost-effective than a Canon flash.
I did not want to spend a lot of money on the flash as for me this niche camera with great picture quality is a stop along my journey of photography. I can only practically afford to own one camera at a time. I once suffered from GAS and had an SLR with many lenses and accessories.
There are limitations to this flash that were not clear to me until I read the owner's manual. There are only two manual settings FULL and 1/16. In other words, the button on the back of the flash gives three choices, TTL, MH (FULL) and ML (1/16). Don't get confused: although this flash comes with a flash stand it does NOT have any slave functionality.
Note that you can adjust flash exposure compensation by 2 stops plus or minus in TTL mode. After two stops, the flash's TTL functionality does not appear to work correctly. For me, this is more an observation about the firmware on the camera than a problem I am experiencing.
Final comment, the small EF-140 flash works very well for non-bounced shots, as it is very powerful for its size and could be all you really need. But it is not powerful enough for bounce (with homemade light modifiers) in anything but the smallest rooms, widest apertures and higher ISO's (400).
