Canon Speedlite 580EX II
Canon have updated the 580EX speedlite to go with the new EOS 1D MkIII. It doesn't look like a very big upgrade, mainly a faster recycle time and a little better construction and weathersealing. However it does include an external metering sensor for non-TTL automatic flash exposure control and a PC socket for use with non-dedicated slave triggers, which could be useful in using the flash with non Canon-EOS bodies.
- Approx. 20% faster recycling time compared to 580EX
- Superior build quality, including a metal foot for higher rigidity
- Max. Guide No. 58 at 105mm setting (GN 190, feet)
- Auto conversion of flash coverage with compatible digital SLR cameras
- White Balance info communicated instantly to compatible digital SLR cameras
- Full swivel, 180° in either direction
- AF-assist beam, compatible with all AiAF points on every EOS SLR
- Dust- and water- resistance to match the EOS-1D Mark III
The popular Speedlite 580EX Flash is being replaced by the new Speedlite 580EX II Flash, which features a host of improvements, including a metal hot shoe with an improved locking mechanism for added durability, an external metering sensor for non-TTL automatic flash exposure control and a PC socket for use with non-dedicated slave triggers. Fully compatible with all EOS SLRs, the new Speedlite 580EX II is gasketed for dust and moisture resistance, making it possible for users of EOS-1 class digital SLRs and many L-series EF lenses to use flash safely when shooting in dusty or wet environments.
