A cheap 21mm finder for the Leica

Cheap and cheerful, it does the job.

Back in the day when I owned a 21mm f/2.8 Elmarit ASPH (they were affordable three decades ago) I used the genuine Leica 21mm finder. That ran some $250 back then and it was pretty awful, with heavy barrel distortion. Today you can spend $1000 on a new one or $400 on the Zeiss (Cosina) version. Reviews suggest that the Zeiss is every bit as awful but you leave with $600 in your pocketbook.

Used beater Leica finders can be found for $300. Voigtländer used to make a couple of versions – a clunky and ugly plastic one (also sold under the Ricoh label) and a rather elegant metal torpedo type which included frames for a 25mm lens and came with a satin chrome or black finish. It’s so-so by all accounts and used ones crop up occasionally for $150 or so.

Why am I writing this? Well, when I reviewed my recently acquired 21mm f/3.5 Voigtländer VM Color-Skopar lens I suggested I would use live view to chimp the rear LCD screen as a composition aid. Well, forget that. It’s a poor experience. You hold the Leica like an iPhone, looking like a real twit, and the display is seldom bright enough to see much in bright light even when set to maximum brightness. So I shopped around and came across this dirt cheap plastic finder which ran me $26.40 shipped from a US seller on eBay:



At that price it’s not a great risk to try.

It’s not going to win any prizes for looks but, amazingly, despite the high barrel distortion (what else is new?) it delineates the field of view of the 21mm lens accurately side to side and top to bottom. It’s also very bright, has no frame lines, defeated all my efforts to photograph an image through it and weighs just 5 grams/0.2 ounces. And it’s a nice tight fit in the M10’s accessory shoe and will not fall out even if nudged. There is no lock on the foot and none is needed. It’s also tiny and fits nicely in my shoulder bag. Sharpness drops off to the sides of the view but not enough to make composition difficult. It’s also set back too far in the accessory shoe meaning that you get a part of the camera’s top plate in the view, but it’s nothing you cannot work around. See below. And it beats chimping.



Tiny.

The finder protrudes slightly behind the top plate but that’s not an issue in use. Below I take a cutting tool to the foot to mount it further forward, to see less of the top plate of the camera in the view than anything else. Plus the protrusion offends my aesthetic senses.

I have no difficulty using it with eyeglasses and the plastic should preclude scratches to my eyewear.

Try it. You might like it.

Making a better fit:

The stock finder protrudes 1/4″ behind the top plate of the camera:



Stock fitting – 1/4 rear protrusion.



A piece of Scotch tape defines where to cut the base of the mounting shoe.



Diamond tipped cutting wheel on the Dremel tool.



Cut carefully, a bit at a time, from the base and the front,
alternating cuts until the two cuts meet. A small Nicholson file is
used to clean things up.



The improved fit. The finder fits tightly enough that the
1/4″ of the foot which has been removed is not missed.
You still see the camera’s top plate at the bottom of
the view, but less of it.



It’s always something. The devil is in the details.
A small white index line is added to show the shutter speed
selected. The finder obscures the stock index on the top plate.
