    I have one of these converters and it works perfectly. Just like the original mercury battery. They are relatively expensive though but should last a long time.

    If a comparable quality OM1+MR9 adapter is less than an OM2, then go for it. Otherwise, why bother?

    Because the OM1 is an all mechanical camera and the OM2 is an electronic, auto-exposure camera. Very different cameras.

    The only other all mechanical Olympus OM is an OM3 and they are quite a lot more expensive.

    ...But, they don't need a battery conversion.

    Have you heard of KEH.com?

    BTW, they lists OM1's that appear to have been converted to use the modern 1.5V cels.

    Despite the received wisdom, electronics aren't necessarily less durable than mechanical shutter trains whose accuracy isn't "forever" as many assume. Fact remains, any OM1 is getting to be a very old camera that possibly led a tough life with little or no maintenance.

    John Hermanson of Camtech has been an Olympus repair technician for many years. He does complete overhauls and part of the overhaul is to convert the camera to take a 1.5 volt battery. And a very reasonable price.

    *All* types of cameras will need CLAs every few decades or so.

    Most people who have actually used different kinds of cameras extensively will have had more electronic ones suddenly fail than mechanical ones.
    Mechanical ones may lose their adjustent slowly over decades (but then I have a 1968 Leicaflex SL, a 1969 Nikon F and a couple of other similar vintage cameras which are nearly spot on and probably never had a CLA).
    Electronic cameras will more often suddenly die and require proprietary circuit boards to fix (which are also likely to be what's wrong with any "parts" cameras as well).

    Re C.R.I.S. adapters: there are cheaper unbranded ones available and one can make one's own as well.

    Just a few points:
    1) The alternatives to mercury batteries are easy to use, accurate, dependable and can also be cheap.
    2) Electrronic cameras are not inherently better than mechanical ones and mechanical shutters definitely *can* accurately expose slides.
    3) For manually focusing a lens, AF focusing screens are almost always *not* better than screens desgined for manual focusing. They may be brighter, but don't snap into focus the same way. Especially with faster lenses.
    4) Newer cameras are not always better than old ones.

    Sorry for the rant....

    Not Germany, but I highly recommend Mike Spencer at http://www.camerarepairs-r-us.co.uk/. he has CLA'd both my OM1n and OM2, changed the foams and converted the OM1n to take SR44 cells. He sorted a dry joint in the meter circuit on my OM1 and he also changed the prism on my OM2.
