This is not true. Nikons do not have databases of thousands of scenes stored in the
cameras. (Think about the technical problems in storing this much data and instantly
searching and accessing it back in 1983; when the FA came out.) What Nikon did was

But then if the built quality were better, wouldn't it be a "higher class"
model then? I think Pentax should drop the 5n and made the 3 as affordable
as the 5n, things would have been more "per

Canon has had some problems with their metering lately, notably the severe
underexposure that the early Elan II's, EOS 3's, and Elan 7's (?) were
doing. I belie

If you think Petersen's Photographic and Shutterbug are great authorities, that may be
part of your problem. Did anyone see the MZ-S "test" in the May 2002 Shutterbug? It
seemed as if the tester hadn't used an auto-exposure camera before. He says Tv stands

The ZX-L manual says that the camera *does* offer center-weighted metering

An advantage of the low cost MZ-L, you can override the film speed setting.

For me, I have never rated slide film at the rating on the box. This goes
back to the 60s and continues to the present. I have always rated the film
1/3 stop faster (32 instead of 25 etc).
Metering habits also have a huge bearing on exposure. Very seldom do I use
the indicated exposure given by a
