Hi all

i bought a yashica gtn to begin my street photography project, and i've some doubts in how to use the camera.
Is it possible to predict the shutter speed turning to the left the f-stop dial? for example starting from 1/500@f8 -> 1/250@f11 -> 1/125@f16?
know the 1/500 shutter speed shouldn't so difficult, just turn to the left the f-stot dial untill the red led/red arrow will disappear, right?

This method could be a little bit accurate? How usually do you shot?

Some one are shotting without battery with sunny 16 rule?

After how much time is better to send the camera to a cla?

Thank you all :)
 
Well... the over/under lights tell you when the camera will pick (exceed?) 1/30th and 1/500th respectively. You could turn the f-stop ring till a light comes on, then turn the other way and count stops. This will get you close.
 
And... Yes, the camera defaults to 1/500th. Without a battery, just load film and shoot sunny f/16.

I tried a couple of times to get a $20 bargain and failed. After a service, you'll have a great $100 camera.
 
Unfortunately, the Yashica GTN/GSN (and the rest of the lot) have stepless shutter timing. It cannot be predicted in the discrete, quantifiable way you are looking for. If it is any comfort, the meter (as long as it has been CLA'ed and contacts been cleaned, POD changed) is quite accurate. However, shooting with the GSN is like shooting on Aperture Priority all the time.
 
Shutter speeds can be roughly predicted if you have any experience using a handheld meter. At a given aperture and film speed, you can use a meter to determine somewhat accurately what the shutter speed will be. In time it isn't difficult to read the light with your eyes, and to guess the approximate shutter speed.

Looking outside now I can see that it's overcast, but not very cloudy. With 400 speed film in my camera, were I to set the aperture to f/8, the shutter speed should be about 1/250th. Setting the aperture to f/16 would give me 1/125, setting it to f/4 should give me 1/500th. It's not hard to predict with a little practice.
 
Red and yellow lights help to estimate speed just like OP sees it. Varying aperture, achieve either light coming on (1/30 or 1/500) and then adjust aperture to value giving you desired speed. Sure it may not achive speed you need - under certain light conditions.
 
thanks a lot for your reply, so you have confirmed what i was thinking...with sunny 16 rule i'm able to predict the shutter speed and seems to be reasonable accurate.

I hope the light meter will work for other many years from now, anyway after how much time it may be not leave me? (in average obviously)

Thank you
