Weird. I know how my Pentax multipattern metering works.

Hi,
PS: If your camera allowed you to set the aperture through the camera or the
aperture ring, don't be surprised if the chosen shutter speed differs a bit.
This is due to the rather loose manufacturing tolerance.

This is not true. Nikons do not have databases of thousands of scenes stored in the

searching and accessing it back in 1983; when the FA came out.) What Nikon did was

Let me try to clarify what I am after.

Is there any quantative way of testing the camera so that I know if it over

No, this is not true. ZX-L is a replacement for ZX-7.
The proof is at Pentax Japan web site: MZ-7 has been discontinued and no
longer listed; whereas MZ-3 and MZ-5n are still in production.
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

Ah...well, this is potentially good news. Pentax may yet bring forth a
capable medium-priced body to replace the 5n. I hope it will have a
center-weighted option that is as easily accessible as it is now on the
1p, 5n, and MZ-S.

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 perfect.

An advantage of the low cost MZ-L, you can override the film speed setting.
Lots of features in an economy body.
