I have problem with flash recharge rate for continuous shots when I cover events.
One alternative is to use a better recharge-rate rechargable battery like enelope.
My friend recently passed me a old external flash with external battery pack. (it is very heavy). This flash is manual flash (wth one contact) as compared with Canon hot-shoes with 5 contacts.
My questions are:
1) Can I use this on 300D/30D but in Manual mode?
2) Will this flash cause long term probelm to my DSLR
3) What other problems?
