Excerpt: This is the first shoe mount flash to pair with my first SLR. So far I am impressed by the features of the flash using iTTL controls. Bounce flash is capable for anywhere with the amount of tilt and swivel. So far I have been able to use the flash on about 150 pictures on one set of AA batteries. I have not had any problem with cycle times.
Pros: Consistent Output, Easy To Use, Fast Recycling, Versatile
Excerpt: I've owned this flash for about a year. It works well and has been durable enough. It's good for P-TTL while mounted on the camera, and it works well as a bounce flash. I've also found it useful as a hair light and fill light while doing portrait work.
Pros: Power, value
Cons: Cheezy hot shoe, Few manual controls, no sync port or slave
Excerpt: When I upgraded my DSLR to a new T3i, I was shocked my older Sigma E-500 wouldn't work with it. After 6 happy years with that flash, I decided to go with its modern cousin that works with the newer cameras.It has been reliable and accurate so far, handling the TTL handshaking with camera with no effort on my part. I use it as my primary flash, from close work (with the built-in diffuser) to bounce flash for family and pets.
Excerpt: I have other flash units that work (after a fashion)but every time you want to use bounce flash or some sort of light modifying device the result is usually gross underexposure. The Sigma EF-610 has the power to do the job.
Excerpt: I bought two flashes and I've yet to use them at their full potential. But for the price and the power they put out I am pleased with them so far. Now I have to get a transmitter so I can trigger them remotely.
Pros: Fast Recycling, Good power output, Good price value, Powerful Output
Excerpt: After much researching of flash units I decided to purchase this Sigma unit for £107 on Amazon UK. First thing you notice when opening the box is just how big this unit is, it looks even bigger when attached to the tiny K-r.
