    A small scall meter capable of incident light metering, could be used mounted on the camera the same way as as lose meter.

    The problem with older hotshoe-mounted exposure meters is either
    • they use selenium photosensor which may well have degraded
    • they use CdS photosensor which require mercury oxide button cells which are no longer manufactured (Wein air cells may or may not be available in the proper size to fit)

    The Sekonic L-208 Twinmate used to be sold with a hot shoe adaptor that could be attached to the meter. Its a decent little meter that is relatively inexpensive.

    One can make silver-oxide cells fit mechanically and electronically. But that would mean some hassle.

    But they are 1.5v and decline voltage over their lifetime, whereas CdS meters RELY upon a constant and unvarying 1.35v provided by mercuric oxide batteries. Simple substitution of alkaline or silver oxide very frequently results in inaccurate readings that cannot be simply compensated with lying about ISO...the Olympus OM-1 is one such example.

    I must respectfully differ. Silver oxide cells are very consistent over their lifetime, whereas alkaline cells are not.

    One cannot just substitute the silver oxide cells for the mercuric oxide cells, because the meter circuit's response to the incorrect voltage does not necessarily result in a linear error. If one reduces that voltage appropriately however (through an appropriate adapter or other circuitry)the meter circuit will respond appropriately.

    ok, so hmmm.

    that's a lot of information, not so much of it to make my choice easier...
    but then I don't much like my 7s.

    Well, you've got a Zorki, and Hi-Matic, and budgeting for a meter. You could sell the lot and get a Bessa, have a nice built-in meter? A Bessa R, R2, or even R3A can sometimes be picked up for a good price. If you don't mind a separate finder/range finder, then the Bessa T is worth a look, they are pretty nice cameras and *tiny*.

    only budgeting for a meter by considering selling the Hi Matic, which unfortunately isn't worth much here in the UK (sorry for assuming you may not be for the UK, but there seems to be mostly people from the States on here), the zorki isn't worth anything either...

    anyway, added all up, unless I'm lucky, I'd need to sell a kidney on top of all that for a bessa

    it still comes with the optional shoe. I got one for Christmas and the shoe was included. Still, I think it is more practical to have it in a shirt pocket.
