The Canon compatible flashes can be used on the hot shoe.thx for the links! what about safety - is it safe to use it directly on the hot-shoe?
You have to read the product description to find out. I know the 285HV did have manual settings as it's very popular with strobists.i also crave manual settings because i'll be using the cactus triggers.
No, I believe they are correct. You can use the Vivitar 285HV off-camera (strobist) but if you were to use it on the hot shoe you could fry your camera because the hot shoe trigger voltage isn't the same as the flash trigger voltage. The 285HV isn't listed as a Canon hot shoe compatible flash.so the things i heard about the vivitar 285HV and the threat it poses to the camera is incorrect?
If the Cactus KF36 is an exact clone of the 285HV I wouldn't use it on the hot shoe of your 400D.that cactus flash looks great! i'm going to read about it and find out why i should choose that instead of the vivitar as i can also use the vivitar on the camera i assume.
That's about $188 US so you could get something like this Sunpak PZ42XC TTL Shoe Mount Flash for Canon E-TTL II for $149.95 (120 €. It has a tilt and swivel head, E-TTL II dedication, 24-105 auto-zoom head and variable power of Full, 1/2, 1/4, 1/8, 1/16, 1/32 and 1/64. Just need to find a place you can buy it from.i'd say i'd spend to around 150€
According to the Sunpak web site, that flash will work on your 400D.i couldn't find the one you mentioned samanax but i did come across this one:
sunpak PF30X flash for canon 400D for about 80€. it looks like it has everything aswell... plus - there are also dedicated triggers for the exact flash model on ebay aswell... now i just need to find out if it can fry my camera or not.
