Pentax AF-330FTZ and Hanimex 325AZ Trigger Voltage

Posted on by

Just a short post about camera flashes and trigger voltage.

Canon specifies a safe trigger voltage up to 6 volts using the hotshoe on their digital cameras. If it’s higher, it might damage the camera. So I have measured the trigger voltage on two older flashes I have lying around, since I didn’t get (m)any hits searching the interewebz.

Pentax AF-330FTZ has a trigger voltage of 3.14V
Hanimex 325AZ has a trigger voltage of 110V

So the Pentax AF-330FTZ should be safe. Hanimex 325 however, isn’t. What’s kind of scary is that I have used the Hanimex on several occasions on my 350D. Luckily no harm done (as far as I can tell).

Fordeler ved å fotografere i RAW-format

Det er ganske utrolig å se hvor mye som kan reddes i et bilde tatt i RAW-format. I bilde ovenfor kan man se at orginalen manger kontrast, og dermed fremstilles som grå og kjedelig. Bilde til høyre er resultatet etter en rask behandling i Adobe Lightroom. Kontrasten er gjennopprettet og dermed kommer fargene klarere frem. Det er naturligvis ønskelig å få best mulig resultat rett ut av kamera, men i dette tilfellet hadde jeg vært litt uheldig med innstillinger, samt at jeg skulle nok ha brukt solblender. Skal heller ikke se bort fra at UV-filteret på objektivet burde vært renset. Men er man først uheldig er det greit å vite at mye kan rettes i etterkant.

Canon 50mm f/1.4 USM Lens

Monday I’ve ordered a Canon 50mm f/1.4 USM lens at a norwegian webshop, and yesterday I picked it up at my local post office. Even though I haven’t tested it much, the results looks promising, and I’m looking forward testing it. For once it’s actually announced great weather this weekend.

I’ve did a few test shot with myself as a subject yesterday. But since my camera, a Canon 350D, has a cropping factor of 1.6, the 50mm equals a 80mm, and then it’s real hard to hold the camera and aim at oneself. The closes focusing distance is 0.45m, and of course I wantet to get more than just my nose in the picture.

Canon 50mm f/1.4 Test

Yes, that’s me.
I stopped shaving when my vacation started and.. well.. you can guess the rest.

I’ll try to publish some more photos on Flickr at the end of the weekend.
