Q. What is the 'B' setting for?

A. With the camera in "B" [bulb], position, the shutter remains open as long as you hold down the release button. Handy for long exposures of night city-scapes etc. You need to take a group of shots at various lengths of time, and hope one comes out, until you get experience doing that. Try 10 secs, 20 secs etc. up to a minute. With the Yashica Electro series, the camera itself can time itself out correctly to 30 seconds at least. A cable release which screws into the top of the shutter release button is a great help in time exposures. These shutter release cables are not only more gentle in triggering the shutter, thereby avoiding motion blurring in the shot, but also usually have a lock that can be enabled to keep the shutter open in the Bulb mode for extended periods.

Q. What are the chances of taking indoor shots without a flash using 100 ASA speed film.

A. The Yashica and Minolta Hi-Matic lenses are so fast, that if you have a room with a fair amount of sunshine coming in through the windows and light colored walls and ceiling, there is no reason that it would not only be possible, but would be a considerable advantage when taking pictures of small children.

Color negative films such as Fuji and Kodacolor are balanced in response to light on the assumption that Daylight or Daylight colored flash will be used. For that reason, artificial light indoors will, depending on it's ratio to sunlight, cause your pictures to lean toward red coloration. Often this can not be compensated for in printing. A picture taken near a sunny window in a room which has both light colored walls and ceiling should require no flash or other artificial light source.

Since you are dependent on reflected light, expect the light that is reflected by your clothing to be noticeable on the subject. Dress accordingly!

Exposures made under fluorescent light will have poor color balance. There are just too many types of these lamps to make having a selection of color compensation filters on hand feasable. The best option is to try to overwhelm the influence of the fluorescent light with a powerful flash.

The use of Black & White film removes this problem and surprisingly, a lot of photographs look better in B & W. Additionally the image in the prints is formed by metallic silver and will not fade like a color print, particularly in contact with some plastic album sleeves which are murder on color prints.

Q. How can I adjust the EXPOSURE indoors ?

A. Fortunately the procedures suggested below can be tried out without film in these cameras. This gives you the chance to make some notes and also to get the feel of the shutter release button in the exposure test mode without firing the shutter and later exposing the film unintentionally.

The shutter speed selection is automatic. To find out if a correctly exposed shot is practical indoors [ or anywhere ], simply test it.

First be sure that the shutter release 'on' lever is in position. Then advance the film so that the shutter is cocked. Set the RED arrow on the lens at AUTO. Set the Aperture to 3.5. This is halfway between 4 and 2.8. [ The smaller the number the bigger the lens opening to gather light ] Frame your shot and slowly partially depress the shutter button until a Red or Orange arrow light comes on in the viewfinder. If the Red arrow lights it means more light is reaching the lens then the automatic shutter speed selector can deal with. Turn the aperture ring to a larger number [ toward 5.6 ] until the light goes out.

If the Yellow light comes on it means there is not enough light for hand held shooting because the shutter speed is too slow. Try increasing the exposure by turning the aperture ring toward 1.7. If the light goes out, great! If not, you need to rest the camera on something or use a tripod. In ALL cases when neither light comes on, conditions for a good shot exist.

[ Unless of course the camera electronics don't work. ] See if the battery test button lights up the little window that shows the frame counter. [ This feature is not on the MG-1 ]

Obviously the smallest lens opening [ highest f. number that you can use ] that results in no lamp being on, is the one to use to get the greatest depth of focus.
The reverse is true. This makes it possible to focus on your main target and throw everything else off a bit to make your subjects stand out from surroundings. Shooting faces?.... focus on the eyes! If everything else is a little "soft" that is usually flattering to your subject.

Q. Can I use filters with my GS camera and what would the thread size be?

A. The entire G series require 55 mm thread screw in filters which are a standard size, and can be found in any well stocked camera store. Lens caps and other slip-on attachments require a 57mm size. Use of a protective filter when there is a possibility of water spray at the beach etc. is a good idea. Using a UV [Ultraviolet] filter is an all around good choice but without a short lens shade, it could pick up a lot of flare. So you need to consider this for each shot. The only lens shade for these camera is really too shallow to help much. Obviously the correct size shade would block the Viewfinder / Focus and Light Sensor.

Using a colored Special Effects or Color Temperature Correcting filter or a Polarizing filter involves making the needed exposure compensation. With the G/GS/GSN series, the only way to compensate for that, is to reduce the ASA Speed setting dial according to the Filter Factor provided with the filter. For example, suppose that you wish to use a filter that has a filter factor of 2X, that reduces the light passing through it by half. If you are using 100 ASA film. Reset the ASA film speed indicator on the camera to ASA 50 to fool the camera into providing the added exposure compensation needed. Don't forget to reset the correct ASA when you remove the filter. The table below makes a handy reference.

No adjustment is required for the Yashica MG-1, CC, CCN, GL, Minolta Hi-Matic and other cameras which have the light sensor behind the mounted filter, so that compensation is automatic.

Q. I have read that using a flash bracket gets rid of red-eye. The only ones that I have seen only displace the strobe by around 5". This is nothing like the stands pros use in a studio. Can this really work?

A.The answer is yes. Based on the number of pictures that I have taken with both bulbs and strobe guns over many years using a flash bracket, there was not a single instance of "red eye". An additional advantage of using a flash bracket is, that in the event that the strobe gets bumped in a crowded setting, the considerable leverage exerted by it will not tear off your hot shoe. On the Yashica the shoe is held in place by 3 brass rivets. Use of a bracket also provides a secure grip on the camera, and will give you an entirely new feeling of control. So now you have 3 good reasons to make that minor investment.

Q. Can I use Electronic Flash outdoors?

A. Any Electronic Flash that is not specifically dedicated to a particular camera will work with these cameras. You do NOT need to set the shutter in the flash position unless you are using your grandfather’s left over old flash bulbs with most of the Yashicas. See the Guide to your model found via the Home Page. Most will 'synch' at all but the highest few speeds. Great for lightening deep shadows on faces in bright sun. It is suggested that you do not use the Hot Shoe. Mount the flash on a generic flash bracket [widely sold] which reduces the chance of Red Eye, by keeping the flash as far from the lens as possible. It also provides a more secure and comfortable grip for the camera.

Q. The Yashica Electro shutters are Aperture Priority, but is there any way at all that I can control the shutter speed? I am hoping to get some shots of my daughter's soccer team in action.

A. That is an interesting question because it has implications for all shutter priority cameras regardless of manufacturer, which have user controlled aperture selection. I believe that Robert Spillman [writing in Amatuer Photographer, published in the U.K.] , may have been the first to articulate this in print with regard to the GT when the camera was first introduced there.

When you understand the relationship between the aperture stops and the percentage of light between them, it actually becomes quite simple to control. Each ƒ stop on the lens barrel, namely, 16 - 11 - 8 - 5.6 - 4 - 2.8 - 2 - 1.4 represents a 100% change from the adjoining setting. As the numbers get larger, the amount of light transmitted by the lens becomes LESS, because this number is NOT the size of the lens opening but is the ratio of the size of the lens opening [aperture] to the focal length of the lens. With this in mind, it is not difficult to follow the procedure.

In daylight photography, set the lens opening to maximum for the sake of simplicity. This is 1.7 on the 'G' series. Now slowly press the shutter release button until you see the red over exposure lamp. Then adjust the lens opening until both the red and yellow lamps are out. At this point your camera is set for the correct exposure with the shutter set at 1/500th sec.

If you wish to cut the shutter speed in half to 1/250th second for the sake of greater depth of focus, move the indicated lens opening on the barrel to the next 100% smaller aperture setting. For example if the lamp went out at ƒ 5.6, decrease the lens opening by 100% to ƒ 8.0
Obviously you can move from one mid point to the next. To obtain an exposure of 1/125 th second, you would move the lens by two increments to ƒ11. Try this without film in the camera to get the hang of it.

There is a really fast and reliable method of of controlling the shutter speed of an Aperture Priority camera. For example a camera used in a photography class workshop must obviously enable the student to control the shutter speed precisely to study it's effects on how an image is captured.

By using an exposure meter, which is a lot cheaper than buying another camera, the meter reading can indicate at which lens aperture to set the camera in order for the Electro shutter to select your intended shutter speed.

The dial of a popular incident meter is displayed here as an example. Set the ASA to match the film in use. In this case 100 ASA. Take a light reading and point the dial indicator [ H which signifies that a high intensity screen is in use] to match the illumination level which the readout needle indicates. This reading as you can see is at 64 on the outer scale.

Now look at the shutter speed / to ƒ stop range. It shows that for the prevailing light condition you would set the lens at ƒ4.0 in order for the shutter to fire at 1/500th sec. If you wanted to take a shot to see how a running stream would look at a lower shutter speed, you may decide to expose that frame with the lens set at ƒ16 which would cause the Electro shutter to fire at 1/30th second. Unfortunately the Yashica Lynx 1000 is the only camera reviewed on this site which enables the lens to be stopped down to ƒ22. This is a major advantage usually overlooked by lens makers today.

Q. The self timer on my GSN is very quirky and sometimes does not complete it's travel. Is this hard to fix?

A. The lubricant in cameras that are 40 years old or more tends to stick the self timers and sometimes they will travel almost all the way but fail to trip the shutter. Sometimes they can be nudged back, but often they jamb leaving you with an expensive repair. I urge all users of the Yashicas and Minolta Hi-Matic NOT to use their self timers. It could wreck your camera. To bring the seriousness of this hazard home, I coined the phrase “Self Destruct Lever” to describe the Self Timer. The solution is to use a shutter release cable and use an outboard clock mechansim to delay the shutter release. These devices may disappear as Digitals take over, so get one while you can.


Q. I have been entrusted with a Yashica GSN which has been in the family since it was purchased by my Dad in a PX. It still looks like new, and takes great shots. What can I do to make sure it remains that way?

A. Excersize the camera from time to time. Fortunately the Yashica Rangefinder shutter can be wound with the film advance lever without the need to have film in the camera. This may help to prevent the old lube from sticking the shutter blades and generally keeps moving parts clean.

Most importantly never leave the battery in camera when it will not be used for a while. You can store the battery by cutting 2 strips out of the plastic can that the film comes in, and threading the carry strap through it. Even if you misplace the battery, that's a lot better than having the camera destroyed if it leaks.

Do not store the camera in it's fitted case. The lining of these cases retains moisture and over time this could cause pin holes in the chrome plating to erupt with copper oxide. Most often seen in cameras from warmer and coastal areas, the pattern is almost always the same, on the wind lever, around the battery test button and the rear view finder. I have no idea why these areas are more vulnerable.

The filter ring mount on the front of the Yashica lenses is made of a very soft alloy. You can almost bend this by just staring at it. I used to joke that Uri Geller got his start this way before he moved on to bending spoons on TV. Robert Murray emailed in a suggestion that will strengthen and protect the thread. ' I have several of the GSN models', he writes, 'and with your help have brought them back to life. One trick I did find is that I look in my local photo stores bargain bins for the ugliest rubber lens hood in there I can get for near nothing in the correct size for the GSN. I cut away the rubber leaving a nice 3/8 of an inch black plastic ring I now use as a lens hood. The rubber part would be in the way of the rangefinder/meter anyway. Since this black plastic ring has filter threads it still allows for filters and keeps the dings away from the metal filter ring. Camera will still fit in the case with this attached and it really makes a good cheap hood'.

I should add that a UV filter will help, and in fact if you can find any scratched or cracked glass filters, simply break out the glass with care and screw the ring into the camera.

Q. Is there any way to take a double exposure with a Yashica Rangefinder camera?

A. On the camera bottom plate is the Sprocket Release pin to allow you to rewind the film when the roll is done without destroying the brass gears. To double expose... press in the sprocket release and hold it in... then wind the shutter with the film advance lever. It may be a good idea to hold the rewind crank just in case there is a bit of friction, so the film won't move. As you begin to wind the shutter the next time without holding the pin, it will pop out and you will be back to normal advance.

Q. I have seen Wide angle and Telephoto lens sets for sale on the web. How useful are they really?

A. One can only surmise that a 45mm Yashinon lens was selected as the primary lens on these cameras so as to give the Japanese user a little extra edge in shooting within the very confined space of their living quarters, land being at such a great premium. Distortion at that focal length can be held within pretty tight standards. When shooting extreme close ups such as portraits, this minor compromise has slightly more ramifications, than using a 50mm lens [the default standard on a SLR]. The use of the Tele Adapter would help somewhat in rendering facial features more naturally. One really needs at least a 75mm - 100 mm lens to get portrait perspective right, and the more that you drop down below that mininum, the worse facial feature distortion gets.The actual effect of these lenses can hardly be classified as Wide Angle or Tele by any means. A step or two backward or forward would do as much at indoor distances. So why even bother to tool up for production, you might well ask. According to my deep throat connection at the time, the rangefinder division used the excuse that they needed to provide a “complete system”, to be taken seriously in the trade, while in fact they were just trying to keep on par with the SLR boys. It was a time during which colour and other emulsions with ASA 25 speeds were in widespread use. Ektachrome, with the required Wratten 85 filter for daylight, was rated at ASA 16. When either lens is in place, the sharpness is reduced and the maximum usable aperture setting should not exceed ƒ4.0. Extending the range of these add on lenses would have cut the maximum practical aperture to a point as to make the lenses unmerchantible. As it turns out, when used to capture shots at long distances such as scenic views, the 0.8X ratio of the Wide Angle or the 1.3X of the Tele, can add up. The most serious disadvantage of the W / T combo however, is the inability to take advantage of what the Yash Electros are all about.....speed!   The reason is, that once you have focussed through the finder, you need to consult the conversion table on the W / T lens and reset the focus to that 'new' distance. The actual "Tele" focal length is equal to 58.4mm. The focal length with the "Wide Angle" lens is 37.7mm.Both lenses accept 72mm screw-in type filters. If the price is right, they would make a nice addition to your arsenal. A companion combo finder which mounts in the flash shoe is required. If it is missing you really can't make much use of the lenses. More data on these and similar lenses from second party makers can be found on the Classics page of this site. This may be your best source for an inexpensive replacement viewfinder. You can view or print out the Original data sheet. This is a large file [316k].

Q. My Yashica GSN is in great shape but the case fell victim to jungle rot. Does anyone still make a case for this camera.

A. The after-market real leather case for the Canon AE1/ AE1P is a perfect fit for the Yashica G through GSN as well as the MG-1 models, and will give your camera a truly luxurious look. The 'secret' is that this case does not use a screw-in fastener at the bottom which would have to match the exact position of the camera tripod socket. Instead it attaches securely to the camera with a snap button loop that goes around each of the carry straps on the camera. These cases fit several other cameras and therefore do not have the Canon Logo on them. The case will not close with the lens shade in place. Take your camera along to the store to check other cases if this model is not in stock.

Q. I read that replacing the original camera mercury battery with another type gave incorrect exposures and that compensation had to be made by adjusting the ASA setting not only with a new battery, but from time to time as the battery charge was getting lower. This is all over the internet. What's the story?

A. The Yashica Electro Rangefinder camera created a revolution by being the first automatic exposure camera that was truly all electronic. It did not require a mechanical "exposure meter" type device [a galvanometer which is very susceptable to shock] to accomplish exposure controls as was the case in other contemporary cameras. It uses a highly reliable relay instead. The designers also envisioned problems that could occur with a system that was directly coupled to the battery. Battery life changes with each click of the shutter even though by an imperceptible decrease

The illustration based on the Yashica Service & Repair Manual shows how the electrical current flows into c/ the Holding tank (Condenser), monitored by a/ the CDS (Valve), b/ Trigger Valve (Switch 4) and flows to the d/ Lens diaphragm resistor. The Battery Test Lamp should turn on when 3.9 Volts are supplied and fail to turn on when the applied voltage drops to 3.5 V.



Q. Murphy's Law and all that, what if I am up a tree surrounded by lions and drop my battery?

A. Without a battery the Yashica G/GS/GSN will fire the shutter at the default speed of 1/500 th second. This would require setting the Aperture at 6.3 for ASA 100 film in Bright Sun. Allow a bit more exposure if the lions are in the shade of the tree, say 3.5. A good time to try this out is when you are not under pressure, so make a couple of test shots the next time that you have the odd frame or two left on the roll. [By the way, dropping a battery on a lion's head has been known to make them quite cross!]
