herbert_hughes Posted February 27, 2007 Share Posted February 27, 2007 Hello all, I know the new 580ex has not shipped yet, but does anyone know if we will get better flash metering as compared with the Nikon flash system? Thanks Link to comment Share on other sites More sharing options...
wandern Posted February 27, 2007 Share Posted February 27, 2007 E-TTL (II) is a body function, not a flash function. Link to comment Share on other sites More sharing options...
bobatkins Posted February 27, 2007 Share Posted February 27, 2007 The 580EX II is basically the same as the 580EX with a faster recycle time and tougher construction. It should give results identical to the 580EX as far as flash metering and exposure are concerned. Link to comment Share on other sites More sharing options...
don_miller2 Posted February 27, 2007 Share Posted February 27, 2007 It appears it will improve metering over the older 580EX on the 1DIII only. Link to comment Share on other sites More sharing options...

matthew_schwarz Posted February 28, 2007 Share Posted February 28, 2007 You just reminded me about this question I wanted to ask: Has anyone else noticed that flash photography often comes out much nicer using the Nikon D100/D200 than with the Canon Reb XT/20D/30D and 580ex?

herbert_hughes Posted February 28, 2007 Author Share Posted February 28, 2007 Matthew, thats the issue I am refering to. It seems as those nikon flash is less problemactic then canon's because of the straight TTL metering, looking to get that from canon.

awindsor Posted February 28, 2007 Share Posted February 28, 2007 Herbert, I don't know what you mean by "straight TTL metering". The only digital SLRs I know to offer off-the-"film" TTL metering were some of the Fuji's. Nikon uses a preflash metering system the same as Canon. Either due to their many more metering segments or due to better algorithms they tend to do a better job but they are not "straight TTL metering". Don, I don't think that the metering will be different with the 580EX II. Metering is a feature of the body only. The 580EX already adjusts to the crop factor. What will be the case with the 1DIII is that you will be able to access the flash CFs from the camera. Link to comment Share on other sites More sharing options...
andrew robertson Posted February 28, 2007 Share Posted February 28, 2007 I know that in the early '80s Nikon had better flash than Canon, and in the '90s they had better flash than Canon, but I haven't actually seen any side by side comparisons that show Nikon to have better flash today. Once you learn how to use the Canon flashes they give good results. Link to comment Share on other sites More sharing options...
steve_dunn2 Posted March 1, 2007 Share Posted March 1, 2007 <cite>The only digital SLRs I know to offer off-the-"film" TTL metering were some of the Fuji's.</cite> <p>Canon's earliest DSLRs (the Kodak ones based on the 1N, which were sold under different model names as both Canon and Kodak products) also used TTL off-the-"film" flash metering. But all of Canon's own ones, from the D30 onwards, use E-TTL or E-TTL II and lack the OT"F" sensor required for Canon's TTL and A-TTL metering systems.</p> <p>I'm wondering if part of this discussion isn't confusing the generic term TTL (meaning that a sensor within the body does the metering based on light coming in through the lens) with the specific term TTL as it refers to an older Canon flash metering system in which metering does not use any sort of pre-flash and is done using a sensor reading light reflected off the film (or digital sensor) during the exposure. All of Canon's EOS flash metering systems (TTL, A-TTL, E-TTL, E-TTL II) are TTL systems in the generic sense, but in practice there are big differences between Canon's EOS flash metering systems.</p> Link to comment Share on other sites More sharing options...
