Talk:Canon EOS flash system

An article of its own?
Does this subject really warrant an article of its own? As it stands now, there are similarities between Vibration Reduction and Image stabilization and this article and the parent article TTL/EOS. As far as I know there are corresponding names amongst various manufacturer's, such as Nikon's I-TTL and D-TTL etc. As such it's not really needed to have an article describing every local name branded by various marketing departments. 85.131.27.93 12:01, 11 April 2007 (UTC) I don't care one way or the other, but as long as nobody objects, why doesn't somebody pull the trigger?

 * Merge all component parts with Canon_EOS_flash_system. Speedlite system is designed and marketted as a complete system even though some of the parts can be used alone. From a reader and context point of view the system would be best discussed as a whole. Leave redirects from ETTL, Speedlite and original article names. Mfield (talk) 17:57, 3 March 2009 (UTC)
 * Merge all as per Mfield. – ukexpat (talk) 18:27, 3 March 2009 (UTC)
 * Merge all since there is very little content specific to each model. Stuartyeates (talk) 20:03, 18 August 2009 (UTC)
 * Merge all I would NOT merge them, it discourages expansion and a lot of those flashes are VERY different and SHOULD be expanded rather than just passingly mentioned. --68.148.4.31 (talk) 22:31, 9 October 2009 (UTC)
 * Merge the individual Speedlite product pages to the EOS flash system article. The current level of detail may run afoul of WP:NOTACATALOG, thus some judicious trimming is probably in order. The presence of separate Speedlite 430EX and 430EX II articles is certainly unnecessary. Even lens articles cover multiple generations in one article (Canon EF 50mm lens and Canon EF 28-80mm lens for instance). &mdash;/M endaliv /2¢/Δ's/ 20:30, 16 April 2010 (UTC)
 * Merge These need to be merged. I'm contemplating how it will be done. I'm a little concerned over the name of the merged article. I don't know if the names are the most logical. I have similar concerns over the naming of the lens articles. In any case, that is an issue that can be addressed after the merge. It's simpliest just to go ahead and start merging as I think we agree the merger. Jason Quinn (talk) 10:15, 8 October 2010 (UTC)
 * I've gone and merged most of the articles. The new article needs to be re-written but even as it is, it's still better than the previous situation. Jason Quinn (talk) 11:41, 8 October 2010 (UTC)
 * I will take a crack at rewriting the introduction. IMO the scope needs to be defined (starting with the EX series is simply where the article is at this point) and there needs to be a bit of introduction of the optical and RF triggering that seems so central to this system.
 * Also the data tables need to be rearranged a bit. I think they're useful, because you can see how the capabilities of the flashes changed over time.
 * There is some confusion about infrared that I'll try to address. In some cases it's pretty inaccurate to call it IR because it's visible, but at least Canon seems to have a consistent approach to its use so it shouldn't be too hard to describe. AL Virginia (talk) 15:35, 30 January 2023 (UTC)

IR master on 580ex II
Hi all!

The article says that the IR master is supported on the 580ex II. There is also a reference. However following that reference I cannot find the info. Also in the instructions manual there is no "infra" word or piece of word.

Can anybody double check and if necessary correct the info? Thanks, -- ★ Pikks ★  MsG  15:32, 2 January 2013 (UTC)


 * Canon does not use the term Infrared. They only use "wireless" to describe their optical flash communication system, which has been shown to work only on the infrared band. Describing it as IR is IMO an acceptable generalization, given that the term is in pretty common use out in the real world. However, I also think the nomenclature in this Wiki should be consistent and not conflicting with Canon's published material. AL Virginia (talk) 12:41, 1 June 2023 (UTC)

Speedlite Transmitter ST-E1
"....It replaced the ST-E1" as far as i know there has never been a ST-E1

The entire early ranges are omitted
The early SpeedLites were the Canolite (011 and 133A to 299T), then Speedlite E/EG and EZ ranges, and only very recently, the EX range. The EZ430 onward especially were very highly rated. Cites:

 * The article is about the EOS flash system, so the Canolite series aren't applicable. Okto8 (talk) 19:19, 28 February 2024 (UTC)

Adding missing A-TTL flashes; separate sections by metering type?
I'm adding info on the early EOS Speedlites which are missing from the article, and I wonder if it would be better to categorize the list of models by metering type (and thus era)? At the very least it seems like it makes sense to separate the A-TTL flashes from the E-TTL and E-TTL II flashes. Okto8 (talk) 19:30, 28 February 2024 (UTC)

Model specs table needs a complete revamp
The model specs table is missing all of the A-TTL flashes, and should be set up with models on the Y axis and features on the X axis, both to maintain consistency with other articles and to limit the amount of horizontal scrolling necessary to visually search the table for a particular model. I plan to do this at some point/. Okto8 (talk) 18:15, 20 June 2024 (UTC)
