Extra Frames on Olympus Mju II? Help Required.

Thomas Keidan · Nov 30, 2017

I know this topic has been covered a little on here but I haven't found a definitive answer... does anyone else manage to squeeze some extra frames from the mju ii? I shot my first roll today and got 26 before the film rewound. Is this normal or could my DX coding reader be broken?

Thanks

We still are waiting on more information on your "quick question" on the film chamber of your sample of the Mju II.

Concerning the early rewind now:
What film cassette did you put into it? There were casettes down to 12 frames.

I put in a 24 roll of Kodak Colourplus 200 and got 26 frames from it, I hope this is able to provide more insight! Thanks

A camera that makes more out of your film... well, I would toss it at once.

Thomas Keidan · Nov 30, 2017

I'm worried that if it is not reading the information on the DX code then it is also not setting ISO properly, the camera uses DX coding to set ISO!

It's not at all unusual to get a couple of extra frames from a roll with these autowind cameras.

Dont worry. Some cameras can squeeze a frame or two more out of a roll before rewinding

AgX · Nov 30, 2017

Thomas, why do not just get your film processed and see what the camera has made out of it.

My experience is that most cameras (at least the ones I own) only use DX information for setting the ISO and ignore number of exposures.

But then there still remains a variety of means and algorithms to stop further exposing.
As far as I remember we never discussed that in depth. But seen the sheer mass od resp. cameras...

Thomas you are a perpetual worrier.
Most people would go "oh cool, I got a few extra shots from this roll...hope the monkeys at the D&P lab don't wreck them".

Explain your thought process as to why you think if the camera was reading the DX code wrongly it would affect the number of frames? It doesn't wind-on a different amount of film each shot depending on whether the canister is coded as 24 or 36: the film is literally longer in 36-exposure canisters.

With all due respects and no insult intended, get a grip, jeez.

You're right, I'm sorry for bothering everyone!

There is no "due respect there" - dude is just start outing out so chill with him yeah?

He has a point, I need some tough love! It's all OK!

You aren't bothering us.
We are actually worrying about how much you are worrying!
The 24 exposure films are long enough to be able to give 24 good exposures in a large variety of cameras. Some cameras are considerably larger than yours, and use up more leader in the loading process.
Enjoy the couple of extra shots you get. Just don't try to force the camera if it stops winding three-quarters of a frame after number 25.

I was worrying for good reason I feel, I understand that most films give a couple of extra shots but somewhere I had read that the Mju II deliberately rewinds when it hits 24 or 36 shots. This got me thinking that maybe the DX code point was faulty and not picking up the film's barcode. As the code also sets ISO according to the DX code reading I thought that this would not work at all either!

Is anything wrong with the negatives or prints from those extra two or three frames? If not, I would not worry.

Dude, you aren't bothering us. Really. I just can't believe the number of banal things you seriously worry about. And it worries us. Go out and enjoy the crisp early winter sunshine before all the wind and rain/ice/snow/hail arrives. And post up your shots.

I tracked down the manual for your camera: https://www.manualslib.com/manual/968920/Olympus-Stylus-Epic.html?page=8#manual
It specifically states that "The final number of exposures may sometimes exceed the number of exposures (identified?) on the film."
Your camera appears to functioning normally.

Yes which suggests that the camera doesn't follow the cassette code that says it is a 24/36 frame cassette and may be triggered by something mechanical such as the "stuck film piece" that Thomas was trying to get an answer on, by sensing that the cassette has wound out the film to its limit. Surely if it simply read the code then it would rewind on 24/36, wouldn't it?

Thomas has a desire to get to the bottom of things which is a good sign, isn't it?

As an owner of a Mju II I am also curious as to what triggers the rewind.

The answer to this one is a test canister of film ( i keep a canister of exposed film thats dud ) and experiment and find out .

Surely it's just like nearly every other auto-rewind camera? A mechanism senses when the sprocket-cogs fail to advance fully when the camera tries to wind on, which triggers the rewind motor. I can't see why it would be any different.

It was common and certainly not unusual to get 39 exposures from a 36-exposure roll of Kodachrome 200 professional version; I remember this very well from using an Olympus OM4 and Canon T90 and that particular emulsion over more than a decade. Of the present day, running a 36-exposure roll of Velvia 50 through a Canon EOS 1N I get 37 exposures.

In autowind cameras, film tension on the take-up spool triggers a clutch that signals the rewind of the film.

pentaxuser · Dec 1, 2017

I won't speak for the OP Thomas but the point I was trying to make has been made for me by Olyman and Poisson du Jour which is that it seems to be a mechanical or electro-mechanical system that rewinds the film on the Mju II. If it does incorporate the DX code for frames then I remain unsure how this is incorporated.

I am sure he needn't worry and it is great if he gets one extra frame but I don't think that was the whole point of his thread and it certainly wasn't the point of my post. I was curious as to what the exact trigger for the rewind is.

OlyMan · Dec 1, 2017

Narrower compacts such the OP's Mju II and his 35RC waste less film at the start of the roll (especially the manual-load 35RC) and have less unusable waste at the end, so it's very easy to get more frames than the indicated number. But the problem I've found is that these 'stolen' unexpected frames are sometimes ruined by careless D&P.
