Excellent. I plan to use the camera in a studio with monolights.
I was reading a book at Barnes and Noble this afternoon about toy-cameras and apparently there are "2 clicks" with the Holga, therefore setting off the strobes twice. Is this true?
Yes, when you push the shutter lever down it fires the flash & takes the picture.
Then when you release the shutter lever it triggers the flash again.
So you do have to be careful in the studio
1: make sure the flash has recycled before you releae the shutter lever, so you are not damaging it by trying to make it fire before it has recycled
2: if you are photographing people warn them that there will be a second flash.
Apart from that it's not a problem & the shutter has closed so you are not getting any exposure from the second flash. I got used to it pretty quickly & just went with the 2 steps described above. If that bothers you then you could probably take the shot & then remove the flash trigger from the hot shoe & then release the shutter. No second flash. But depending how many shots you need to take you will be fiddling about with it for every shot, remove & replace. But that is another option. If you were Annie Liebovitz you could just stand there & have one of your assistants remove & replace it.
