Hi there
New here tend to ask daft questions, love daft replies
Just found the above but have no idea what "transistorized electric eye " is
In fact there seems to be very little on this camera that i can find
thanks
wendy

Hi Wendy.
Not a camera or a brand with which I'm familiar but I suspect it's some form of either autofocus or focus assist device.
Also, feel free to start an introduction thread. Let us know who you are and what you're into. It's a great community and forum and always good to have new folks join the film fanatics.
Regards, Paul.

Its looks too cheap for a sophisticated system like auto focus It hails from 1971
Halina was founded by Dr Haking Wong who comes from Hong Kong That always makes me laugh sounds like a song title
I know halina had about this time someform of auto exposure but I am clueless to this electronic eye
Its full title is Halina easy matic computer which seems a tad advanced for the year unless it was just an advertising ploy
I dont collect old cameras they just seem to appear in my bag
I will post some images if anyone is interested

Great - look forward to seeing them.
Don't forget to check out the various podcasts, etc as well as the forum.

The electric eye is just for auto exposure. The circuit probably has a bc107 in it somewhere to justify the 'transistorised' tag.
The camera takes 126 film. Not sure you can get it anymore.

Thanks Peter
I assume this would be done by shutter speed ? or was it selected apertures must have been rudimentry if it was

This isnt the most inspiring camera but I love the cheap and affordable ones as these are the money makers for the top line camreas
The explosion of phone cameras can be disasterous for the big camera companies if they dont get into that market and ultimatly for the ameuters
-
usually, these systems vary the shutter speed using small electromagnets. It probably releases the front shutter and uses the transistor to time how long before releasing the back shutter.

Don't know. If there's no manual aperture then I would think it's got a combined aperture/shutter mechanism - the shutter opens a variable amount so alters the aperture. If it is working you could probably tell just by watching the shutter as you fire it while pointing it towards and then away from the light. You should see a difference.

Would that not give an odd negative?

No. The shutter is in the lens. It's like having the aperture at some setting smaller than maximum aperture. It just makes things darker.

Ah I was thinking a simple leaf shutter due to the cheapness of the camera and didnt really consider a multi leaf shutter, Its a thought
-
It may be simple. Some of them are just two parts cut as a V that overlap. It's the fact it's in the lens that means it won't have any strange effects.
-
It's true, most modern point and shoot combine the shutter and the aperture. But this is an oldie, so I'm tempted to think it's probably closer to a Polaroid's shutter in design than anything else...
But either way, it works just fine.
-
You might be right Francois but combined aperture/shutters have been around for at least forty years that I know of. Minolta Hi-Matic F for instance.
-
Just checked mine and you're right.
-
You have a easy matic Francois and its a shutter aperture set up
Is that correct
Jumping the threads gets confusing for my wooley head

I think he meant he has a Minolta Hi-Matic F.
-
Yep, it's a Hi-Matic from Minolta... and it's probably my ugliest camera. Not that the design isn't interesting, but mine is so dented and held-up with tape that it's a miracle it still works! It's the one that had a frozen focus and heavily dented filter threat that I had to straighten using a hammer and a dowel! Not pretty but it worked.
