verschil sigma flitsers EF500 DG ST of EF500 SUPER

[markymark]

wie kent het verschil tussen deze twee flitsers ?
met welk gamma zijn deze te vgl met canon ?

zou zijn voor canon 10d

De ST kan je misschien het best vergelijken met de Canon 420EX; de Super is bedoeld als tegenhanger van de 550EX. Let wel, de 550EX beschikt over enkele extra functies en handigheidjes, die de Sigma niet heeft. Niettemin kan je voor die prijs niet klagen, ook al is de bouwkwaliteit duidelijk minder.

Let wel op met een 10D, want het E-TTL protocol is niet identiek aan de voorgaande EOS modellen. Zorg dat je in elk geval een "DG" model koopt, want de 500 Super (niet-DG) werkte niet of slecht met de 10D. Van alle Sigma flitsers (voor Canon) is bekend dat er in combinatie met sommige EOS camera's problemen zijn met consistentie van belichting. Ik zou je dus aanraden om bij een winkel te kopen waar je eventueel mag ruilen voor een Canon flash, in het geval dat de Sigma niet correct werkt op jouw toestel.

Deze week heeft iemand nog een link gepost naar de uitgebreide E-TTL bespreking op Photonotes, maar ik vind 'm even niet terug. Misschien dat iemand anders je op het juiste spoor kan zetten.

volgens otto knap zou die sigma 500 super 100% identiek zijn aan de Canon 550. zou zelfs uit zelfde fabriek komen...

Op http://eosdoc.com/manuals.asp?q=ETTLDx is een heel mooi overzicht van functionaliteit te zien van onder andere de Canon 550EX en de Sigma 500 Super

Ogenschijnlijk zijn de Canon en Sigma elkaars evenbeeld, doch de Sigma heeft minder functionaliteit.

Zal voor veel gebruikers daarop neerkomen, dat klopt, maar graaf maar eens wat dieper in de link die Wunjo postte.

Bekijk dit maar eens:

Kleine quote uit het artikel: De verschillen

The 550EX has custom functions; the EF-500 Super does not. The EF-500 Super therefore does not provide some of the same options as its Canon counterpart.
CF 1 disables the auto cancellation of flash exposure bracketing (FEB) at the end of the three FEB shots. This way you can use FEB for the whole roll if you want, without having to reset it every time.

CF 2 changes the sequence of FEB to under, normal and over-exposures instead of having normal first.

CF 3 disables E-TTL and reverts to straight TTL. This is a very useful option when working with optical slave flash units, which can be triggered inadvertently by the E-TTL preflash.

CFs 4 and 5 control the amount of time that elapses before save-energy (SE) mode kicks in while in wireless mode. CF 4 controls whether SE is engaged after 1 hour or 10 minutes when the flash is in slave mode. CF 5 controls the length of time during which the master flash can wake up the slave flash - either 1 hour or 8 hours.

CF 6 enables or disables the 550EX’s AF assist light.

The 550EX has an AF assist light that covers a very wide area - all 45 focus points of the EOS 3 AF system, in fact. There are two caveats to this. First, the light does not cover the upper and lower focus points on the Elan 7/EOS 30/33/7 and second, the light is much brighter in the centre of the coverage area than on the sides.
The EF-500 Super is much more limited in this regard, as its AF assist light works only with the central focus point on cameras with multiple points. If you select a side AF point then the camera body’s internal AF assist light kicks in instead.

This isn’t a problem with EOS cameras with red AF assist lights built in such as the Elan II/EOS 50/55 unless the body’s internal AF assist light is blocked by a large lens or lens hood. However it could be an issue when the flash unit is used with bodies such as the Elan 7/EOS 30/33/7 or Rebel 2000/EOS 300 or pro bodies such as the EOS 3 and 1V, all of which lack body-integral red AF assist lights.

Note that the EOS 5/A2(E) and 10/10S cameras will not activate the AF assist light of any external flash unit, but this is a limitation of the body and not of the flash.


The 550EX does not cancel FP mode (high speed sync) flash unless you deliberately instruct it to. However, the EF-500 Super inconveniently cancels FP flash mode if the shutter speed drops to the camera’s X-sync speed or below. And it won’t re-enable FP mode until you set the shutter speed back up above X-sync.

The 550EX is about 1/4 stop more powerful than the EF-500 Super. (the 550EX has a rated metric guide number (GN) of 55 and the EF-500 Super a rated GN of 50) Which is part of the reason for the faster recycle time (see point 11) of the EF-500 Super.

The 550EX has an interface that’s easier to understand and operate. The EF-500 Super makes do with fewer buttons but has more menu selections to do the same job.

The 550EX motorized flash head zooms out to cover a 24mm lens. The EF-500 Super only covers a 28mm lens. Each flash unit, however, has a built-in flip-out wide diffuser panel that both makers overrate to 17mm coverage. And each flash head can zoom to cover a 105mm lens. (note that the focal lengths and coverage areas mentioned assume the use of a 35mm film camera)

Flash exposure confirmation is a small LED (light) on the 550EX and a blinking indicator on the LCD of the EF-500 Super.

The 550EX has a three position power switch - off, on and SE, the 90 second “save energy” timeout mode. The EF-500 Super only has two positions and is normally in a 90 second power save mode. However, if the Sigma unit is acting as a master or slave in a wireless setup, or is in optical slave mode, it will never shut off.

The EF-500 Super can operate as an optical slave unit. (in this mode the flash unit will trigger in response to any burst of light from another flash) The 550EX cannot. Unfortunately this mode is limited by the fact that you must apparently meter the flash output manually.

Wireless ratio control. The 550EX identifies wireless groups as A, B or C. The EF-500 Super identifies the groups as 1, 2 or 3. Functionally they’re equivalent.

The 550EX has a high voltage socket for using Canon’s Transistor Pack E or their Compact Battery Pack CP-E2. This port is also used by the Turbo, Mini/Megacycler and Jackrabbit batteries for very fast full power recycles. The EF-500 Super has no such high-voltage connector. However it does recycle 25-30% faster than the 550EX while using AA batteries.

Some users have reported compatibility problems with the EF-500 Super’s implementation of wireless E-TTL. The 550EX does not have such problems.

The 550EX works with all Canon digital cameras which support EX series flash units, including the digital point and shoots. Sigma make no claim that the EF-500 Super will work with Canon’s digital point & shoot cameras such as the PowerShot Pro 90, G1 or G2. It doesn’t work correctly with the G1 or G2. Reports are inconsistent as to whether it works with Canon’s first round of second-generation digital SLRs - the 1D, D30 and D60. Apparently it does not work correctly with the EOS 10D. Sigma have announced a DG version of the flash which is supposed to be digital-compatible (see below).

The 550EX is nicer, has better controls, is solid and reliable, feels sturdier and is pretty well guaranteed to work with all future Canon cameras which support E-TTL. The EF-500 Super lacks a few 550EX features, has some minor incompatibility issues as outlined above (particularly the AF coverage area problem), has a cheaper-looking boxier case, has a poor reputation for reliability and may not work with all future E-TTL capable Canon cameras - but it costs roughly half as much.
