Excerpt: very well-made flash with great specs at a good price. fully featured. i got this several years ago and have been using it since without any problems. a very reliable flash. it has about the same power output as pentax 540 fgz with ability to perform popular pttl functions, like hss, wireless pttl. one beef i have is there is no button for hss, but instead you press the left arrow when in pttl mode until it says 'fp' , I guess that is sigma's own name for 'hss'.
Summary: This is a great flashgun for the price. Very powerful and the exposures have been spot on with my D200 and S5 Pro. Plenty of features but these flashguns are not made for professional use. Three of these have died on me each one only having covered around six weddings and just outwith the one year warranty period. Highly recommended for the occasional flasher on a budget but if you are a pro stick with Canon or Nikon guns.
Pros: Fantastic value, powerful, just as good as Nikon or Canon flash units
Summary: This flash offers a whole bunch of options for a relatively cheap price. The zoom covers a broad range and the slave options are what would be expected. However, there are a whole bunch of shortcomings. No PC input. So if you want to use this with your PWs, forget about it. The flash is cheaply constructed and feels that way when holding it. The design of separate buttons for tilting and turning the flash is an unfortunate choice on Sigma's part.
Pros: Powerful, Price
Cons: Cheap Construction, No PC Input, Slow Recycle
Summary: This is a really cheap flash that looks good on paper. Quite powerfull and delivers good exposure as a single flash unit on any Canon DSLR. I however puchased two units to use in master/slave setup on my 20D camera and did not get one single correct exposure. I talked to the vendor several times, but he could not help. I also searched the web for help but it seemed like I was using the correct settings.
Pros: Quite powerful, good in single flash mode (on 20D), cheap
Cons: lesser build quality, master/slave function (on 20D) do not seem to work
Summary: Nice flash very powerful and the wireless feature w/ my Minolta/Sony system is very good. I have to say that this is my first wireless flash and the creative options it opens are fun. I can't think of a negative since it sells for so much less than the comparable Sony unit. Recomended!
Pros: Excellent integration of wireless flash, powerful
Summary: Easily as good as the Canon unit - remember, E-TTL is a feature of the camera, not the flashgun. Can't see any reason to buy the much more expensive Canon (unlike lenses where I believe Canon is clearly worth the premium).
Pros: As good as the Canon at two thirds of the price
Summary: I have a Canon 20D and used a Canon flash that I had had for quite a few years. It was very similar to the 420EX. It finally broke and the cost to fix was prohibitive so I researched flashes and came down to either the Canon 580EX or the Sigma EF-500 DG Super. They are mostly equal in all ways that I could determine. The 580 has a slightly higher guide number but they are both powerful flashes and the Sigma integrates very well with the Canon body.
Pros: Most of the same features as the Canon 580EX
Conclusion: Att använda: 3 Hållbarhet: 4
Hittade en begagnad på Tradera som funkar fint. Har liten erfarenhet från liknande blixtar, men det underlättar så klart vid portträttfotografering och macrofoto. Menyerna är något krångliga och instruktionerna ganska sparsmakade. Men inställningsmöjligheterna är okej utifrån mina krav. Har noterat som så många andra att blixtfoten känns ytterst vek.
Pros: Ljusstark och relativt enkel att använda i auto-läge
