yo guys, can someone share how difference is flash among them? i am current using canon 40d.. wanted to get a 2nd hand flash to try out. most of the photos taken are target people expressions and places at time...

can someone share what are the differnt kind of flashes suitable for me and any good but not tt ex flashes available?
 

whats your budget? whats ex to you may not be ex to others..
 

but why some flashes costs only abt 200 plus while some can cost up to 800?
 

but why some flashes costs only abt 200 plus while some can cost up to 800?

some reasons i can think of:

- guide number (flash power output). Higher = more $$$
- swivel function
- auto-zooming (can follow your camera lens' focal length)
- automatically adjustable output based on metering (TTL or similar)
- wireless capability
- last but not least: BRAND
