Panasonic Lumix S5

Big frame, small body.




The S5 is in the middle.

There are no certified sales statistics for higher end cameras so it’s impossible to determine whether MFT is dying, as some chat sites aver. It’s probably fair to guess that all high end camera sales are falling in the face of gains made by cell phone cameras, but the new Panasonic Lumix S5, a full frame mirrorless DSLR, is interesting nonetheless.

The image shows that the S5’s body is actually smaller than that of the MFT GH5 at left. The large ‘pro’ FF S1 is on the right. I like the fact that there are several buttons available for common adjustments, in preference to the horrors of dialing through multiple choices on the rear LED display.

Panny is making the body available with a 20-60mm f/3.5-5.6 kit zoom for a package price of some $2,300. That’s a very wide lens and small maximum apertures are no longer a concern when it comes to viewing, making for an excellent all around package for those who remain reluctant to accept the general superiority of the iPhone 11 Pro and later versions yet to come. Through the lens viewing, owing to the automatic brightness correction of the electronic finder, means that maximum aperture no longer matters. That lens and a short tele fast lens or a modest tele-zoom would make for a powerful and compact kit.

Restoring engraved lens markings

Easily done.

Back in the previous century when men were Men (and women were not Men) camera lenses were set in metal and distance, aperture and related markings were engraved and filled with contrasting paint. With age the paint either fades or falls out, making for a hard to use and unattractive tool. (Modern lenses use plastic, with awful screen printed numbers. Once these wear off you are stuck).




The $13,000 Leica Noctilux of today.
Yes, they still use paint in the engravings.

I have had this issue with Leica lenses and more recently with a tool in my garage, a low range Husky torque wrench which covers the 20-200 inch pound range (1.7 to 17 ft.lbs. or 2.3 to 23 Nm). The paint in the vernier markings on the rotating barrel had completely disappeared, testifying to years of use of this wonderful tool with low torque fasteners on those relatively soft alloy cases on BMW motorcycles. This made it very hard to set torque in the relatively low, non-directional light in the garage. Easily over-torqued, once you strip a female thread in one of these engine cases you are in a world of hurt. And that’s easily done without the proper tool. Forget doing it by ‘feel’. ‘Feel ‘ is for lovers, not mechanics.

The process of restoring those markings is simple.




The affected part is thoroughly degreased using isopropyl alcohol.


The fill in paint is generously applied in all directions.


The paint is wiped off with a rag, leaving filled in, engraved numbers.

Amazon carries the paint sticks in a variety of colors. Before use, be sure to shave the end off to reveal fresh paint, as the surface layer will have dried, and store the stick in an air-proof baggie to extend its useful life. And if torque wrenches are your thing, store them un-tensioned or prepare to deal with the consequences.

Analog rocks

Wild complexity allied with reliability.

Mechanical carburetors provided the right air/fuel mixture to internal combustion motors for most of the 20th century. With few exceptions, they are now obsolete, replaced by computer controlled fuel injection devices.

While not as complex as, say, a mechanical watch, these devices are nonetheless exercises in complexity that a Rube Goldberg could revel in.

My 1975 BMW motorcycle uses two Bing carburetors and every decade or so I have to dismantle these to replace worn or rotted rubber seals to ensure that the air/fuel ratio delivered to the combustion chambers of the horizontally opposed, air cooled twin motor is more or less correct. I say “more or less“ because the nature of the mechanical complexity of the device means that precision has to yield to accuracy. Approximately right beats completely wrong in this instance. The penalty for this approximation compared with modern fuel injection systems is maybe a couple of miles per gallon lost in fuel efficiency. The reward is the parts will remain available for the next century, whereas the fuel injection system’s computers will all be unavailable by then. You can read about Bing’s long history here.

Here’s an exploded diagram of a typical Bing mechanical carburetor:

The late 1950s Leica M2, which I would argue was the best 35mm film rangefinder camera ever made, was even more complex, yet every bit as capable. Just like that Bing carb, disassembly, cleaning, lubrication, replacement of rubber parts and adjustment were simply rituals one put up with in exchange for using the best. You happily succumbed to these requirements in exchange for the sensual joy of using the finest analog machines invented by man:

My M2 was sold many years ago when better digital cameras came along. The Bings, however, soldier on after over three decades in my care. And that’s because the BMW Airhead has yet to be improved upon.

Nagel Pupille

Small and complex.

German being an ugly tongue, I quote one of my favorite jokes about the Master Race in French:

“Pourquoi faire simple quand on peut faire compliqué ?”

That’s not quite right as the original translated to “Why make things simple when complex works just as well?” but it’s close enough. And French makes it beautiful.

Never was a camera more deserving of this appellation than the 1930’s Nagel Pupille. Ostensibly a roll film camera taking 16 3x4cm images on 127 size film, it was distinguished by a fine choice of optics from Leitz, Zeiss and Cooke. ‘Pupille’ is French for the eye’s pupil, and the Germans had the good sense not to use the functional but ugly German “Schüler”.




Twin Lens Reflex, if you please.

The stock camera was an eye level finder design, but you could go Full Monty and go nuts at the same time with the twin lens reflex adapter shown above.

Putting aside that piece of lunacy, it was a great camera with fine lenses, ideally suited to the 127 film format, a far more compact version of the larger 120 size, offering 33% of the film area and delivering excellent quality. For those concerned about accurate focusing, Leitz offered a clip-on rangefinder which added little to the ergonomics of the twin lens reflex converter.

The rangefinder is uncoupled. After determining the subject’s distance, the reading on the circular dial had to be manually transferred to the lens. Naturally.

August Nagel, the Pupille’s designer, went on to design Kodak’s line of 35mm Retina folding cameras.

Werra and Bauhaus

Severe and beautiful.

The German Bauhaus movement (1919-33), headed by architect Walter Gropius, gave the world unrelieved ugliness when it came to buildings. If ever there was a model for the bleakness of the Nazi concentration camps, the humorless, colorless and severe Bauhaus style was it.

But when it comes to cameras many good things came about, perhaps the most famous being the Leica M2. Eschewing the embossed finder frames of the M3, the M2 was a study in severity and cleanliness of line and arguably the acme of rangefinder camera design with its uncluttered ‘one frame at a time’ finder which displayed 35, 50 and 90mm frames when the related lens was bayonetted to the beautiful body.

But there’s another design which takes the Bauhaus aesthetic far further and it’s that of the East German Werra.




The Werra I of the mid-1950s.

What is especially noteworthy is that the camera was designed within the Soviet block, not one known for its originality, commies generally preferring to steal designs appropriated from Zeiss Ikon and, when it comes to motorcycles, BMW. Indeed the Russkie copy of the BMW airhead bike, which goes under the name of Ural, remains in production to this day and yes, it’s genuinely awful.

But the Werra was special, with its clean lines and integrated design. While later designs added rangefinders and exposure meters, spoiling the lines, the original Werra I was gorgeous to behold. The only function on the top plate is the shutter release. Film was advanced by rotating the collar at the rear of the lens. Indeed, I recall selling these as a kid and thinking that the grinding noise accompanying this act did not predict longevity. I was right. Apertures, focus and shutter speeds were adjusted with concentric rings on the lens and the baseplate housed the exposure counter and rewind knob. And that was it. The provided hood reversed to protect the lens, along with a screw-on cap. The leatherette trim was standard black or, far better, olive green.

A beautiful design, one which was last made in the late 1960s. Examples can be had for a song, which is about what they are worth, for many were made and you probably need two or three just to get one working example.
