View Full Version : using the "T" setting question

14-Nov-2011, 07:12
I have a 180mm f5.6 Schneider Symmar S MC, Copal. Last evening I was taking some shots at dusk and needed to keep the shutter open longer than the 1 sec max on this shutter. I thought I could set the speed to "T" press the release to open and press the release to close the shutter after the number of seconds I wanted.
It didn't work that way...I pressed the release and it opened the shutter but when I pressed it again it did not shut?

I am embarrassed to ask this basic question but what is the "T" for and what is the proper way to use it?

you have it correct- press to open, press again to close

No need to be embarrassed. The way you think it should work is the way it should work.

... so now you still need to figure out why it didn't work for you. Did you use a cable release or the release lever (it really shouldn't natter)? Does the shuttter otherwise work as it should? I would suspect that the B or T levers (inside parts of the gutys) are gummy and your shutter might need an overhaul. If so, you'll probably also notice that the 1 sec timing is slow and sluggish too.

I will check to 1/sec speed to see but it seems to be fine. The x/sync port will not trip my flash either?

You need to get your shutter serviced. There's a number of good service people. We should have a sticky or FAQ for that.

Could I get some recommendations for a good service facility? That would be a good sticky.

KEH, Atlanta. Only 25 miles from you , isn't it?

There are others that people like: Carol Miller at Flutot's in CA; Paul Ebell, somewhere in the midwest I think; Steve Choi in CA.

If the shutter has not been used much, it may loosen up just by being exercised (fired) a bunch of times.

That being said, if it's to that point a CLA (Cleaning, Lubrication, Adjustment) would still be in order to ensure reliable firing and times.

Just make sure that you're not using a cable release that has a ring-lock. Some of these have a screw flange that acts like a "B" setting, holding the plunger down.

On occasions, this can feel like it's released when it hasn't, not allowing the second firing to release the "T" setting.
