As I acquire items I will try and write a short item on each product with brief notes on operation and features and also talk of features the item doesn't have or can be tricked into having. This way you are not digesting sales literature but actually reading a real users report.
Most cameras you can take out of the box, put a film in and after a few seconds of fiddling with controls, start shooting. The F70 is not one of those cameras, you must read the manual before taking it out of the box. Once you understand the basic control method it becomes very easy to use.
First thing is to describe the maybe significant features the F70 doesn't
|No depth of field preview||With the lens set to the aperture desired (aperture priority or manual mode), press the lens release button and gently move the lens as though removing it. Only a few degrees movement will allow the aperture to stop down to see the effect of the aperture chosen in manual or aperture priority modes. Then twist the lens back to the home position.|
|No multiple exposure ability||Hold the back firmly closed and slip the back latch down as though to open the back, take the first shot. Then release the latch button and take the second shot. The camera is fooled into not feeding the film when the latch is open. Make sure the back doesn't open!|
|No high speed flash sync||Can't do it. Flash sync is limited to 1/125 sec maximum shutter speed, unlike the F90x, F5, F100 which can sync up to 1/4000 sec when using the SB-28 flash albeit with lower flash output and only manual setting, not TTL.|
|No LCD panel light||Now this is a pain when trying to do mode changes in the dark. You have to have a little torch (flashlight) handy and a third hand to manipulate everything.|
To understand the camera operation a little better, it may be time to look first at the part most people fear. The main LCD and the control buttons.
Unashamedly I hereby present a portion copied from the camera manual....
Controlling this nuclear submarine style battle station computer display are essentially only two buttons and a thumb wheel.
My usual cheap and stingy flat bed scanner photo.
The "Function" button is the biggest button in the left hand group and
used in conjunction with the thumb wheel selects the function (thumb wheel
dim in this view, but is on the back just below the LCD panel) .
Eight function types with no flash and ten function types with flash. In
the LCD diagram the functions are the eight fan shaped segments, the little
arrow head in the bottom of each segment indicates which function is selected.
In the above shot everything is displayed but in real life only one arrow
head at a time appears.
Summary, hold the Function button and rotate the thumb wheel to select the desired function.
Once the function is selected then release the function button and hold
the "Set" button below it. Now when rotating the thumb wheel the various
modes that can be selected within that function are indicated. When the
desired setting is reached then release the Set button and the camera is
Summary, hold the Set button and rotate the thumb wheel to select the mode within the function.
For instance, to change the metering mode from matrix to spot, hold Function button, rotate thumb wheel to function marked (15) in red in the top diagram then release function button, hold Set button and rotate thumb wheel until the spot meter is indicated, release the Set button. The mode will stay even with power off.
It is not necessary to go through all the functions in detail, but rest assured that it is a very versatile camera indeed and the simple two button and thumb wheel interface makes life simple in the long run. A half hour read of the manual will tell you everything you need to know.
In the canned program modes or in shutter priority mode, the aperture ring has to be set to the minimum (f/22 whatever, plus lock it with the little latch on the lens). The camera makes the decision on what aperture to use and displays that on the top LCD panel and in the viewfinder. If not set to minimum then the aperture display shows "FEE" instead of the current computer determined aperture.
In manual or aperture priority mode, use the lens aperture ring to set the desired aperture. As usual, the aperture ring does not have to be on a click stop, it can be anywhere.
The top LCD panel and the viewfinder will show the true aperture in one stop steps even though the actual aperture may be something slightly different. It shows the aperture change that occurs when you zoom a variable aperture lens. It also shows the aperture change when you close focus a macro lens like the AF 105/2.8 D macro.
Other buttons seen in the drawing on the left are "out" and "in", these are used to store and recall custom modes that you frequently may use. One stored mode is reserved for factory default settings and three stored modes can be customised.
On the right side are the usual shutter button, the on/off switch and two more switches for controlling auto focus area and canned program modes - portrait, sport, landscape etc. Hard to see in this shot on the right side near the thumb wheel is the auto exposure lock button.
To rewind the film at any time two top panel buttons are pressed at the same time.
I remember one person complaining in a forum about how hard it was to
take a number of shots with exposure bracketing. Obviously he had never
actually used the camera.
To set up exposure bracketing hold Function rotate to item 12 (if flash is on you can select either ambient bracketing or flash bracketing), hold Set and choose the bracket value you want. Then take the three shots, under, on, over. If you need to take another bracketed shot at the same settings then quickly press Function button and then Set button and it is ready to go again. Very quick to do. By defaulting back to normal operation after a bracket operation is the safest state to leave the camera in.
In operation the camera is very smooth to use and the noise it generates is fairly low. The mirror slap can be heard but not motor gear noise when the film winds on (unlike my very noisy N8008s/F801s). Rewind can be switched to slow mode to make it less disturbing if you need to rewind in a church or quiet place.
The flash TTL operation is handled by a five segment off-the-film sensor and is more accurate than the usual single sensor. This flash sensor has nothing to do with the normal matrix ambient light sensor which is located near the prism on top. The flash sensor is down in the bottom of the mirror box. See my other page for metering info.
The flash operation is even more clever when using an appropriate flash
on the camera (or the pop-up flash) in conjunction with a D type lens.
The flash sends out up to maybe 16 very small normally invisible flashes
just after the mirror goes up and before the shutter starts moving. In
conjunction with the distance information from the D lens the pre flashes
test the scene sector by sector until the logic works out in which sector(s)
the subject is located. Some assumptions are made, like, if no or very
low reflectance from some sectors then they are assumed to be unimportant
background so are ignored in the final flash output control. There is no
single clear explanation I have seen of how this logic works, every description
I find has a slightly different story. When you are using a non D type
lens then the same multi segment decisions are made but the lack of distance
focussed information may lead to different results. The pre flashes are
reflecting off the face of the closed shutter at this time. This pre flash
sequence adds no apparent delay to the shot being taken.
Once the logic is happy with where the subject is located then the pre flashes stop and the shutter is opened and the flash fired at the appropriate time, now the critical segment (or more) is the area where the camera knows the subject to be so that segment(s) of the five segment flash TTL meter is the area that controls the flash and when to turn it off. At this time it is measuring the light bouncing off the actual film surface.
This more clever flash control allows a person to be anywhere in the frame against a black sky background or even a reflective background like a mirror and the person will be exposed correctly.
Remember it is the distance measured that counts so if you have three people spaced out so that one is close to you, one a bit further away and one further away again, then it will be the person you focus on that gets the correct exposure, the others will be under or overexposed depending on their relative distance to the focussed subject. People have complained that this feature does not always appear to work but the suspicion is that they are judging prints where the lab could have got the print density wrong by averaging it over the whole scene. The only way to test this feature is to run a slide film through under all possible configurations and then judge how good it is. From there on, better communication with the processing lab is the only way to get good results.
If experimenting with this feature, comparison flash shots can be taken by turning the camera to manual mode where the pre flash test sequence is not used, only the five segment TTL sensor is used to measure the light coming back off the film surface.
Reputedly the Nikon system is way ahead of others in tricky situations but remember that the pre flash sequence is turned off in camera manual mode and when the attached flash head (SB-28 etc) is not pointed straight ahead. Set the flash head down 7 degrees as though doing closeups or set it up/sideways for bounce flash and the pre flash sequence is turned off. So far I am not sure what happens when the flash is attached to an SC-17 cable and held away from the camera.
If using a remote slave trigger like the SU-4 or an SB-26 set to slave mode, then the pre flash sequence or red eye reduction must not be used. False triggering will occur. Go to manual mode to disable it.
Even though the ambient light metering and flash TTL metering is very clever, it still won't work correctly in 100% of cases, but it does dramatically improve the situation over earlier efforts.
A comment in the camera manual under the section Exposure Compensation
lets users know that they know the camera can't do everything....
"We do not recommend using any manually or automatically applied exposure compensation when using Matrix Metering. If you identify an extreme condition under which Matrix may have some difficulty, such as a severely backlit scene or one with extremes of contrast, we recommend using your camera's other built-in meters, Centre-Weighted or Spot. Ultimately, only you know what the subject or part of it requires in terms of exposure measurement."
It's a very nice camera to use with a very good function set. The only
things I may miss from time to time are depth of field preview and multiple
exposure, but it can be tricked to do both those anyway.
My wife has been using the nice, simple, but works well Pentax MZ-50 and on one photo outing when she had battery problems she borrowed my F70 with the Nikon 28-105 lens and had no problems even though I left it in aperture priority mode and she had never used the camera before. OK she didn't have to change any mode settings but she was doing both daylight and night time exposures with it on slide film and all turned out perfectly. Plus she said she liked the feel of it and how it worked.
Some people think that the F70/N70 is an "underpowered" amateur camera
but it really is a better camera than the F90x/N90s as it has more features
built in (and you can trick it for DOF preview and multiple exposure) and
a slightly more modern auto focus module. Unfortunately it doesn't have
the same size auto focus motor as the F90x/N90s, but it does handle the
S model lenses with the ring motor built in. For a carry anywhere camera
it is light and has the advantage of the pop-up flash.
Sean Mulcahy asked...
I am trying to use my N70 in Aperture Priority mode with flash, but
it seems that whatever aperture I select the view finder screen shows over
When I use the Portrait mode it all seems to work, with the N70 selecting an aperture that I tried in the AP mode.
Is the meter lying to me or am I totally confused?
I tried all the fiddles on my F70 and the answer seems to be....
When you pop up the flash in any auto exposure mode (with one exception below) the shutter speed is limited to 1/60 up to 1/125. OK, the 1/125 is the fastest shutter speed you can use and still get full flash coverage of the frame, the computer limits the slower speed to 1/60 to try and stop camera shake being evident if you've got reasonable background light. Trouble is, depending on film speed and aperture chosen (if in Aperture Priority mode) that 1/60 to 1/125 range may show either under or overexposure in the LCD display. Which will show up in the background exposure, but the flash will be OK.
If you go to the "portrait" or whatever program mode, the computer doesn't tell you it's under or over, it just doesn't want to bother you with this fact.
The "cure" for this is to use appropriate film speed for the situation if you want backgrounds properly exposed in your flash shots, if you keep getting overexposure indication then it appears you are using fast film in daylight and attempting fill-flash. A neutral density filter may help with the background light but will decrease your flash range something savage.
If you were getting under exposure message then you could select "slow sync" mode (flash symbol + "slow") where the shutter, with flash on, will select speeds as slow as 30 seconds. You will need a tripod for this mode.
It appears that the camera is trying to help you but also in some modes it confuses you a little by displaying more information than is probably needed at the time.
And Hi to Shirley,
The flash does vary but I think your problem may be the printing. The print labs just average the scene and all shots of different densities come out looking the same. Ask the lab to print with same density through the test shots.
