hexar af triangle on negatives

[ampguy]

anyone know what the purpose of this is?

 

[rogue_designer]

I haven't seen. Is it an open triangle along the frame edge? Might be for an easy place to mark a select?

Marks the roll as being exposed by a cult camera ... Seriously though, it's nothing else but a signature.

 

[sahe69]

To make it easier to identify film exposed with the Hexar?

edit: sorry others were faster it seems. Anyway, this is really a useful feature that I wish was used more by the camera manufaturers.

Yes, this is a very cool little thing that Konica did, and presumably not all the same model cameras have the marking in the exact same place, so you could tell which of your two Hexar AFs shot a particular roll. It's on the Hexar RF and the S3 also, and the Koni-Omegas have a way to mark little dots on the film (you can select how many you want to appear). Other makers do it also, such as Hasselblad.

ahh

ahh

So that's why Tom and Katie have been calling ... it's been useful to me, quickly lets me know what wasn't shot on the GSN, F3, and Chinon 😀

when the scientologists partnered with konica in a joint venture, this was implemented to calibrate the e-meter in the camera - it also encodes a gps microchip on the negative strip so that it records exif data as well as tracks your movements

It's a tiny triangle just outside the upper right hand side of the negative, like a nick, about 1/4 from the top. I'll have to check my other haf negatives later to see if they're at a different spot.

I have that on both my hexar black and hexar silver.

I may be wrong but I believe that Tom Abrahamsson said once that some of the old timers would put nicks in different places on different camera to identify which camera had taken the picture, when looking at the negative. I apologise to Tom in advance if my recollection is wrong, but it struck me as a really good idea.

..rushes home to check my negs..

It's on the Hexar RF..

FWIW, when I purchased my first H-AF, the explanation was that in the production process the triangle cut-out is designed so that a plunger can push the stamped metal interior out of the mold.

Yep, I've also heard this, though don't remember where/who.

All 35mm Konicas since 1960s (even half-frame) and some other Konicas, have a small index cut in a different place according to which model, on the short edge of the frame (it's usually a tiny rectangular nick rather than triangular and on the wind-on side) - thus you can identify 1. whether a Konica, and 2. which model Konica, took the shot . On Konica at least, this is not a manufacturing quirk but an aid to users/processors/or the manufacturer in matching camera to film. Also most films are easy to get the right way round when printing, but a few scientific films were glossy on both sides and had no edge markings - so this could help there too.

Tom is correct. Many pros would have the frames of their cameras notched (differently in the case of multiple, identical bodies), so as to know whish rolls of film went through which body. This way, in the event of a malfunction (sticky/dodgy shutter, etc.), it would be relatively easy to ID the problem camera and send it off for service. Marty Forscher of Professional Camera Repair did a lot of this "notching", but I don't know if he was the first to offer this service. Wouldn't be surprised if he was.

Cooleth thy jets...all the Hexars have 'em (half-moon-shaped), as does the Auto S3 (triangle). So, for that matter, might my Konica Lexio 70 p/s, albeit in a seriously different fashion (not a notch at the frame edge, but a perforation away from the frame edge, but I'd have to confirm this).

When I see a pic of Cruise or Travolta totin' a Hex, I'll believe it. The Illuminati, however, are a whole different story, but I can't talk about that...😉
