50 exposure loads

[walter_schade]

<p>Can anybody tell me if it is possible to use 50 exposure cassettes in an LX? If so, how do you load it properly? Thanks to all.<br>

<p>LX counter goes only to 36. To load 50 exp film in LX, you need to load at 12; and you must remember you must pass the 0 mark the second time, then pass red dot, stop at 36, take out cassette.</p>

Thanks a ton for the fast reply. Your expertise is much appreciated.<br>

<p>I don't think this would work:<br>

I believe that, in order to get constant frame spacing, the amount that the take-up spool rotates for each frame decreases as the counter gets close to zero. So starting the counter at 12 would might make the first frames overlap or at least be too close together.<br>

<p>Annthony is right,loading at anything less then #36 will not work. Loading at #12 only get the<br>

film moved 10mm, less than the required 12mm, therefore all the pictures after #12 up to #0 overlap into one piece.<br>

The only way is to load at #36 as usual, then shoot pass 0, from #36 again, BUT, after passing<br>

through #36 the second time, the frame spacing will suddenly jumps to 5mm wide, in other words, every 2 frames you shoot 2nd pass #36, you lose one frame, that is to say you probably<br>

can shoot at most 46 frames .That is not too bad.

 

I rather recommend, forget about squeezing more out of 50 load in LX, just shoot it as 36 exposure film, than take it out.

There is no point in getting extra few frames, to stop at #30, then take the big trouble of push pull +press shutter another 30

times in order the reset the counter back to zero. Better still, find a Minox B or C

[anthonykosky]

<p>The problem is that the Minox doesn't have a way of measuring the length of film advanced at all (no perforations), so it has to control the amount of rotation of the take-up spool, which seems like it would be much more challenging, and a testament to the genius or Walter Zapp. <br>

As the film advances the diameter of the take-up spool increases so it has to rotate less with each wind to compensate. Presumably with a thicker film, the spacing will increase towards the end, while with very thin film they'll become closer together.<br>

<p>Using thin film such as Agfa Copex Rapid for 35mm film slitted into 9.4mm with, film thickness is 0.12mm slightly thinner than Agfapan (0.1375mm),hence the frame spacing is not as wide and even as using Agfapan, but still will not overlap for whole 36 exposures.<br>

But do not try to slitter the 16mm Agfa Copex unperforated film stock into 9.4mm for Minox, as this film stock is extremely thin, only 0.068mm, if loaded into Minox, only the first 7 frame do not overlap, the next 10 frame overlapping less then 1mm, after than overlapp >1mm; the last 4 pictures overlapping about 2mm.</p>

<p>If you still try to use the 16mm Agfa Copex Rapid in Minox, you may try to use the 15 exp load<br>

spool in lieu of the regular 36 exp spool. The short load spool is slightly thicker, you may get first 15 pictures not overlapping.</p>

<p>I use the 16mm Agfa Copex only in my Edixa 16 cameras, use the 35mm Agfa Copex slitter for Minox.</p>

Minox frame length remains constant before #0, at 12mm, ie, 1mm frame spacing, after 0<br>

the frame spacing increases to 5mm</p>

[MTC Photography]

<p>It is more efficient to use 50 load film in Minox EC. instead of LX; with the EC you can shoot pass 0, (yes you CAN shoot also at #0 and #red dot ), thru #36 a second time, then stop at<br>

#29. Push twice to pull the exposed film into cassette, take it out; THEN MANUAL ROTATE<br>

THE COUNTER DISK TO RESET THE COUNTER TO ZERO, without the tedious task of push-pull-release for 30 times.</p>

[MTC Photography]

<p>Actually you can also load the 50 exp film into LX, starting at counter at any number greater than #26, then shoot a total of 46 frames, without overlap|( the spacing is hairline thin)<br>

<p>If start at #30, shoot past 0, reddot, #36... stop at #22</p>

<p>If start at #27, shoot pass 0, reddot, #36...stop at #19</p>

<p>Do not load 50 load at any number < 27, that is where overlapping begins.</p>
