    spot meter review: bewi zoom spot

    Here is a little review of the old Bewi Zoom Spot meter.
    Before I begin, here’s an article on the meter.

    Translated from German.

    In the 1960s, the era of classic light meters ended up being the most important recording accessory. Almost all newly developed amateur cameras had integrated exposure systems.

    In parallel, although cheap cameras without built-in exposure meter. However, these often only had a fix focus setting for occasional users who did not know what to do with recording accessories anyway. The professional area covered gutters with the Lunasix and some elaborate Spotmeter from Japanese production.

    Most of the light meter manufacturers gave up at that time. Gossen and Metrawatt got together and specialized in high-quality measuring computers. The traditional manufacturer Bertram, Munich, undertook in 1968 with this elaborate measuring device a last attempt to survive with a high-quality (and high-priced) product on the market. In parallel, the BEWI BOY was built as a low-cost device. Although this BEWI ZOOM SPOT was quite powerful and technically able to keep up with the Japanese spot meters of Pentax and Minolta, he was not given a long life. Bertram finally gave up production in late 1982.

    The zoom spot has two measuring ranges LOW / HIGH, which are switched with the gun button. The measuring angle can be infinitely adjusted between 35 ° to 1 ° with the side knob. A rotary pointer on the back alcala indicates the set measuring angle. The subject to be measured is aimed at the viewfinder, the needle is locked when the button is released. The displayed measured value (1-17) is then transferred to the setting scale as usual. The device is handy and easy to use. The power requirements are quite demanding; 2 pieces of PX27 are needed.

    Values: Sensitivity 9-39 ° DIN / 6-6,400 ASA; Apertures 1-45; Exposure times 8 hours - 1/2000 sec .; Light values ​​-6 to 20; CINE 8-19-108.


    I was in the market for a spot meter and was looking for a small one, I read about this one and went searching.
    I picked one up from eBay they go for very cheap.

    I read a forum post here regarding batteries for the meter. So I picked up a couple of S27PX batteries. They fit nicely.
    Butkus has the manual for the meter online. here.

    I tested its accuracy with a comparison against a sekonic 308, and a grey card.
    After calibration it was matching the 308 in all light conditions.

    It’s quite an impressive Spotmeter. Very pocket friendly.
    Here are pictures of the meter.

    If your looking for a alternative to the Pentax and other spot meter. Try this one. It’s not for everyone as it’s analog match needle.

    My next project will be adapting a zone scale to it.

    One thing that I always check in a spot meter, is to make sure that the little circle in the view finder is aligned well with the sensitive area in the meter. One can check this by looking though the view finder and slowly bringing a black edge close the the edge of the viewfinder's circle. Test all the way around the circle with both vertical and horizontal black edges, and by turning the meter a little.

    If the alignment is off, you'll see this by examining how the light reading responds as black edges approach opposite sides of the circle.

    My first 1 degree spot meter was a Soligor (I think), and the sensitive area was poorly aligned with the circle. I had just purchased it brand new. So, back it went, and I bought a new Pentax V. The alignment was perfect in this 2nd meter.

    I've used one, they're a good cheap all-purpose meter if you don't mind fiddling with the batteries.

    I just got a Bewi Zoom Spot light meter. Did you by any chance progress with the zone scale? Would be very interested (just created the account to ask:P).
