I imagine this problem has been covered here before, but I'm gonna vent anyway.

After maybe 10 rolls of film, my new (used)early model TL-120 apparently now is giving different exposures on the pairs. They look at least a stop off. The f stops openings look the same size thru all the stops, and testing the speeds at the slowest ranges doesn't reveal any obvious lag.

Of course, between the last time I shot with it and finally developed the slides, I sold my Spud! ;-/

At least I have enough decent backlog for maybe a year or two on the MF folio...

I have never heard of that before, Lattie. I highly recommend you contact 3dworld and tell them about the problem. I had aproblem with my camera and their customer service was stellar.

Hi Lattie,

No chance that you might have maybe attached a filter to one lens - then got distracted and forgot to attach the other filter to the other lens?  It might sound silly but I've been silly and done it myself before.  I once did a whole shoot with a twin rig and had one lens cap still in place on the camera that I didn't look through!

Only other thing is that I have noticed slight differences in my own TL120 but mostly with very contrasty films where I notice the difference in the edges of any black areas in the shot.  I've never had it happen using Provia 100.  Just a thought or two.  Hope it helps.

regards,

Harry Calderbank

Haven’t played with my TL-120 for a while (but I expect to take it to the ISU Congress later this year) but I can’t help wondering if a failing battery could possibly cause this problem?

I replaced the batteries not long ago - but that's a possibility (anyone else had that experience?). When the last battery's were dying out - the shutter speed just defaulted to 1/1000th, as the manual says it would

I bought this already used, no warranty now - I can still get OK service?

I think Bob Aldridge's guess is a good one. It's hard for me to imagine what
would cause the difference unless it was some kind of linkage to the
apertures, but you've mentioned they look similar.

As far as warranty goes it will not hurt to contact 3D world. I believe they
will fix your camera for the cost of shipping it round trip. That would
probably be cheaper than taking it to a repair shop that's never seen one
before. And mine was back in about 8 days. Pretty amazing service.

Good luck!

I had the shutter speed issue with dying batteries when shooting a fashion show. The flash goes, and I hear a click with no idea that I'd discovered I lost 5 rolls.

The low-battery shutter could be defaulting to 1/1000th, with no flash sync. I don't usually use the prism unit, which gives a battery indicator.

John mentioned to me that cold weather can give shutter problems - and I was attempting to shoot a freezing waterfall!

Yours has a battery indicator? Now that's spiffy.
Can you tell us what it looks like or snap a picture of it?

fwiw, I don't think I'd expect a _low_ battery to behave the
same as _no_ battery. 'twould be interesting to have you
drop the battery from your camera and see if your shutters
again fire correctly.

> John mentioned to me that cold weather can give shutter problems

To be clear, I mentioned that the shutter on my TL120-1 is
currently un-reliable when the camera gets cold. That's not
to say that my camera can't be used _in_ the cold, just that
I can't let it whole unit reach that temperature.

I didn't explicitly mention, and maybe should have, that my
TL120-55 works flawlessly regardless of the temperature.
Since it is nothing but a TL120-1 on which I have bolted
55mm lenses, I don't think there is anything inherently
wrong with the shutter design which precludes its use in
cold weather.

Cool!

I thought the exposure red/green lights (in the earlier model) flashed or gave some indication of a low battery. I guess I have to look into the manual again ;-)

I think the question is if by "unreliable" shutters in the cold, do you mean a speed difference between the lens pair, or a generally inaccurate, if matched, speed for both.

Mine beeps when it is low battery. I don't think there is
any indication on the meter.

I mean "no workie". When the camera chills to about 15F, I
can press the button on my TL120-1 and the shutter does not
operate. I suppose in that regard we could say they are at
least synchronized.... at 0/100 of a second!
