Its the same lens, but Sigma has 2 different mounts. One is for Canon, the other is for Nikon |

has been... used in heavy downpour (more than once may i add!) You are an absolute muppet for using a high voltage electrical object in the rain. That's not just me taking the mick, that really is a serious warning to you and everyone else. To the best of my knowledge no manufacturer professes the waterproofing of their flash units even in their professional units; certainly none recommend it. And using high voltage in the wet? |

Omg... just when I thought I can buy 2 bodies and share the lens..............
Lol ...Btw... Nikon must be written all over my face.. I asked for Sigma 70-300 without taking my camera out of my bag... and they straight away handed me a Nikon-mount one .... ![]() |

I agree with jed on the flash in rain bit. Dangerous if u consider the voltage of the capacitor! For the record, i do not hold my camera by the flash when not in use. Trust me, if i did, it will break everytime i do it since my setup tends to weigh upwards of 7kg, not to add with a tripod attached. Canon flashes do NOT lock properly. Just check out the mechanism and u will realise it. The best thing nikon ever did was to revise the hotshoe in the sb80dx, i hope canon does it soon too! If u have to walk great distances with the flash attached to the camera, and u are walking cross country terrain (sungei buloh or worse), my advice is to keep your flash. Get a belt pack or something. I have broken the hotshoe too many times because of vibration. When the flash is left secured by just 1/2 the hotshoe, it tends to break the hotshoe.
Btw, nikon to canon adaptors can be found in the market. No AF though. |

I am an electron...if I remember clearly...physics...swimming in the opposite direction to current flow...

normally i will switch between different brands of cameras only when one particular brand has a certain good model... haha.... that was when i use normal cameras...
now when i use dslr .... i found that i would have to stick to one brand for a long time due to investments in the lens and other accessories... but i found both nikon and canon very good..... |

I had some experiences with AC shocks....my aquarium light dropped into the water and the funny thing is that the ELCB doesn't trip (maybe coz of lousy design). Now the outer metal layer is energised due to water in it and i touched it. I don't think a lot of current is flowing but the thing is that you know you are being f**king shocked like hell (i could hear myself mumbling vulgarities...think it was cbcbcbcb) but you cannot control your hand, you just hold on to it and vibrate. Luckily my wife was around and threw the ELCB to off. I also had an incident with flash cap shock during my sec sch days. Was dismantling it and forgot to discharge. You just feel the jolt and threw it away automatically. The cap was rated 400V i think . Last edited by 2100; 24th December 2004 at 02:36 PM. |

However, they do not ensure as secure a contact as the SB28 and older flashes which have the screw lock.(though prone to jamming) One has to regularly check the hotshoe and tighten if necessary with the new foot. With the older units, it was nvr required. |

I remember my physics lecturer emphasizing over and over again that "it's the current that kills, not the voltage". Never quite fully understood the whole current vs voltage concept (yet managed to pass!) but I think in this case you can't really build up enough current from 4 AA batteries to kill yourself. I could be wrong. Yes, voltage may be high, but I remember Van de Graaf generator can generate up to 50,000 volts but you can touch and still not die.
I think a better reason not to use a flash (or any electronic equipment) in the rain is that you might kill the equipment! Now THAT's definitely been known to happen. Duh! |

the capacitor is a high charge one. Caps are never rated in volts anyways. Overall, the rate of discharge of a cap is really quick and the amount of charge in it is well....high. Therefore, the current is also very high. But nvm.
Overall, i agree that the sb80dx (thats my only exp) is a bit shaky at times, but the metal securing pin holds it down so u don't drop or break it. However, the 550 uses the same concept but the pin is screwd down and also spring loaded. Just go check out your 550. Canon had a reason for it. Apparently, if the shoe breaks, its cheaper for u to repair than if u tear the whole top 1/2 off if u're using a non-pro camera made of plastic, esp those with a pop up, cos all the electronics are there (at least thats what i was told). Howerver, can someone tell them that if u drop a flash from tripod level, everything made of plastic, all habis! |

Move from Nikon to Canon in July 2004 - learning to love my 300D more and more.

hi
haha jed, u may be right about e dangers. but e shots turned out great! :P during my first reservist, e signal officer got a dose of lightning strike. and we were very close by. and since we are always called back in e rainy months of nov / dec, i think that is a greater hazard man :P |
