roguewave Posted January 23, 2008 Share #1 Posted January 23, 2008 Advertisement (gone after registration) I just purchased a Metrawatt / Leicameter MR as an additional aide to getting up to sped with the M3. Along with my trusty Gossen Digisix, I hope to get my eyes back into shape to forcast EV better. Any insight/ help about the use,care & feeding would be much appreciated. I have drawn on your wisdom & good graces in the past without fail and stand before you anxious to learn. Thanks again for all the input and recommendations past & hopefully the near future.

I used one for many years on my M3, and it was very easy to use, and accurate as long as it was working! It eventually was beyond repair when a botched previous repair (by a company in East Anglia whose name I cant remember) meant the switch inside broke. You will need to do something about the battery which is no longer available, I used the Wein cell alternative. Gerry Quote Link to post Share on other sites More sharing options...
cocker Posted January 23, 2008 Share #3 Posted January 23, 2008 Hi Ben, i have a black one and a chrome one. I find them both reliable when used with my M2. It's said that you get an indication of the metering area if you bring up the 90mm lens frame lines. As Gerry said the main issue is battery power. I have a little adapter sold by a business in the UK that allows you to use currently available batteries. MR-9 Adapter. Replacement for PX625, PX13 or MR9 discontinued Mercury cells..

luigi bertolotti Posted January 23, 2008 Share #4 Posted January 23, 2008 Do you need its original instructions ? I remember a site in which you can find good reprints of old manuals... but haven't saved the link, sorry... Quote Link to post Share on other sites More sharing options...
Irishimage Posted January 23, 2008 Share #5 Posted January 23, 2008 I have the black version (MR-4) also and use it hand held with my IIIc and IIIg, i'v also installed the Wein Battery and use the battery check before any shoot. Find it very accurate outdoors in good daylight conditions but a little bit of a guessing game when it comes to indoor with available light. Still a beautiful little meter .

earleygallery Posted January 23, 2008 Share #6 Posted January 23, 2008 As above, the metering area is approx. defined by the 90mm frame lines. These meters are getting on in years now, the VC meter (which is also shoe mounted but not coupled) or a good handheld meter is definately a better option.

Joop van Heijgen Posted January 23, 2008 Share #7 Posted January 23, 2008 Advertisement (gone after registration) I do use the Varta V 625 U (1,5 V) for the Leicameter MR-4 on my M4. The meter gives good results. The MR metering is somewhat shorter, but that gives no problems. My Leica RE gives on 'integral' the same results as my Leica meter, and the RE have an excellent meter system.... Leicameter MR-4 Quote Link to post Share on other sites More sharing options...

Hi Ben, Leica Meter MR instruction manual, user manual, free PFD camera manuals Here is the original MR manual. The MR4 differs only slightly.

Guest tummydoc Posted January 24, 2008 Share #10 Posted January 24, 2008 The MR-9 adaptor adds about 1mm of thickness compared to the PX-625 battery. That's rarely an issue with threaded battery compartments, and even fits OK in the CL, but the MR meter's battery compartment cover is a thin, pivoting piece prone to breakage. The added thickness of the MR-9 bulges the compartment cover outward and puts a lot of strain on the pivot. It is a simple task for someone who knows how to recalibrate the MR for 1,5v batteries. The silver-oxide version retains its accuracy over time whilst the alkaline version tends to lose voltage (and hence, accuracy) as it is used-up.

roguewave Posted January 24, 2008 Author Share #12 Posted January 24, 2008 Keith, you have my highest admiration. We call someone like yourself, ready willing & able to assist a True Boyscout. Hard to get through life without them. Thanks for the links, very interesting reading. Gerry, sorry for your loss. Luigi, Keith's got you covered. Noel, Thanks for the info on the Wein Battery & check off system. JoopThe Varta is available widely in NYC, thanks for the head's up. Richard, I 'll call leica NJ to see how many months they'd need to relcalibrate and release. A good option for the summertime. Vinay, very enlightning. I'll take this to heart. To all thanks for the assist and getting me up and running. I posted my 1st image with the M3 and am happy to say, I loved the whole process all over again.

Guest tummydoc Posted January 25, 2008 Share #13 Posted January 25, 2008 I do use the Varta V 625 U (1,5 V) for the Leicameter MR-4 on my M4. The meter gives good results. It is often the case that due to age and/or corrosion, some older CdS meters designed to function with 1,3v will have "self-adjusted" to where a 1,5v will give passable results, at least through part of the metering range. True re-calibration requires adjustment of both potentiometers (low and high range), otherwise the metering isn't linear (i.e. it is accurate at one end of the brightness range but increasingly inaccurate toward the other end.)

That's correct; personally I do use the MR to get an impression of the light; I do not need a very precisely metering; the MR is more made for a general metering and fast photographing! Most photographers needs too much time with metering.... The M6 metering has made the M Leica very slow in use... Quote Link to post Share on other sites More sharing options...
bill Posted January 25, 2008 Share #15 Posted January 25, 2008 The M6 metering has made the M Leica very slow in use... God, I feel better now... Up to that point I was coming close to agreeing with you! I was going to have to have a lie down in a darkened room to recover - but there, right at at the end, you did not let us down - a nice unfounded sweeping Joop-ism presented as an incontrovertible "truth". Plus ca change... Regards, Bill Quote Link to post Share on other sites More sharing options...

They love people who can say everything that no one can disagree with while no one can understand what they mean.You have an art in doing that. We in England have a word that describes that but its rude so I won't say it here. I would love to see some of your pictures - do you have a link?
