The thing that impresses me most about Leica? Its innovation

01 Nov
Ok, so maybe there’s still room for innovation when it comes to memory card access.

It might sound odd to discuss the innovations of a company whose best-known product is anachronistic to the point that you have to take the baseplate off to change the film memory card, but I’m serious.

I know I’m supposed to be impressed by the company’s history, its (rather outdated) use as a press camera and the stellar reputation of its lenses. But I’m not, especially*.

I love that Leica doesn’t just have crazy ideas, but that it turns them into workable, purchasable products.

It’s not that the lenses aren’t great. It’s just that I’m not terribly impressed a company’s ability to make single focal length, manual focus lenses good when money’s essentially no object and you can individually correct every one if you have to. My experience of working as an engineering journalist always reminds me that it’s many times harder to produce a kit zoom that has to offer decent performance at multiple focal lengths, offers fast autofocus for both stills and video, includes image stabilization and can be made with a degree of consistency for something like $ 35.

But while I’m not that fussed about all that ‘red dot’ business, I love that Leica doesn’t just have crazy ideas, but that it turns them into workable, purchasable products. Even if they’re not necessarily the most affordable ones.

Take an ‘e’ (off the word Monochrome)

The Bayer color filter array is amazing. It lets spectrally-indifferent sensors perceive color and does so with a good level of resolution and fairly few downsides. Except that it steals around a stop of light.

I love the idea of a mono-only second camera. But perhaps not one that costs more than my (admittedly ludicrous) road bike.

So why not make a mono-only camera? None of the softness and noise that comes from demosaicing, and better, cleaner image capture because you’re not letting a series of color filters absorb half your light. That’s a great idea, why doesn’t someone do that?

Well, Leica has, with the Monochrom series of cameras. They do exactly what you’d hope: produce super-detailed mono images.

Of course, given that you have only one ‘color’ channel, it becomes more important than ever to avoid clipping, so I wish there was monochrome camera that didn’t meter by looking at the light reflected off the stripes painted on its shutter blades. Also, since it would need to be a second camera for me, I’d prefer it to cost less than a small car. But I have to applaud Leica for doing it, rather than just thinking about it.

What’s the opposite of Iconoclasticism?

Again, who would have thought it’d be Leica: a camera brand that added a faux winder lever onto its latest camera, that would design one of the most innovative user interfaces of the past decade?

Love it or hate it, the icon-led touchscreen interface of the Leica T series is one of the few genuine attempts we’ve seen to completely re-think how you should interact with a camera and its settings. Interestingly, the person I’ve met who dislikes it most is also one of the few I know who owns a digital Leica rangefinder (though that could be because the first iteration had some interesting quirks). Personally, though, I thought the design struck a good balance between command dials that controlled the primary exposure parameters while letting you tap and swipe the settings, just as you might on a smartphone. Certainly an ambitious thing for a ‘traditional’ camera company to do.

Settings? There’s an app for that

On the subject of smartphones, it’s long been suggested that they might provide a solution to the uncontrolled menu sprawl that’s overwhelming even the best-designed modern UI. Connecting cameras to smartphones over Bluetooth and Wi-Fi is becomes ever more easy and ever more commonplace, just as the complexity of menu options becomes unbearable, so why not pass-off responsibility for settings to the phone?

Handing off responsibilities for camera settings to a smartphone app makes great sense. I’m not sure the same is true of taking away the rear screen or adding a faux-winder ‘thumb rest.’

And, if looked at from a certain angle, that’s what Leica’s M10-D does. I’m not necessarily convinced that it made sense to keep going and take the entire LCD screen away but pushing set-and-forget settings off to a smartphone app I could get behind. An app can offer a nicer interface with better guides and instructions, meaning the on-camera interface can be stripped back to focus on the main shooting parameters. But perhaps leave me a screen, eh, Leica?

You can’t be serious?

I don’t want flippant tone to completely undermine my sincerity. I genuinely am more impressed with Leica’s innovative thinking than the specifics of its products. I’d love to see some of them more widely adopted. Like having a 36 x 24mm image capture area, that might take off.


* Full marks to every comment or blog post concluding that I don’t ‘get’ Leica. To be clear, I love shooting with its rangefinders. They deliver a unique shooting experience that every keen photographer should strive to have. Even if I wouldn’t necessarily recommend spending the cost of a hatchback (or a nice road bike) on one.

Roger Cicala finds innovation sealed inside the Sony 35mm F1.4 ZA

Sony FE 35mm F1.4 ZA teardown

We’ve already looked at Roger Cicala’s teardown of the Canon EF 35mm F1.4L II, where he showed it to be a heavy duty design with extensive adjustability to bring it back to spec after a period of abuse. LensRental’s look inside the Sony FE 35mm F1.4 turned up a lens designed with a radically different approach. It’s easy to over-interpret the differences and start trying to picture the different use-cases they’ve been designed for, but even if you don’t want to extrapolate so far, it’s fascinating to see how unconventional Sony’s approach is.

Taking a more linear route

The most fundamental difference Cicala highlights between the two designs is how the focus elements are moved. The Canon uses a traditional helicoid design – rotating the focus element along a helical track, in much the same way as manual focus lenses would. The Sony design instead uses a piezoelectric drive to push and pull the lens element along a rail, meaning that there’s no rotational movement occurring at all. Instead it can be shuffled back and forth in very fine increments.

Sony calls this design ‘Direct Drive SSM’ (with SSM standing for Supersonic motor), and it’s based on technology used for in-body image stabilization in Sony A-mount cameras, hinting at the speed and precision that such systems can provide. It’s distinctly different from the linear motor technology used in the FE 55mm F1.8, which you can see in operation here.

Direct drive SSM

The Piezoelectric drive mechanism is fascinating, and we saw it embedded in a cut-in-half FE 35mm at CP+ last year. It involves a drive element that can be expanded or contracted by applying an electric current. Expanding it slowly moves the lens out along its mounting rail, but the connection to the rail is designed to slide in response to rapid movement, so rapidly contracting the drive element leaves the lens in the more distant position but with the drive element retracted. Repeating this pattern of slow extension and rapid contraction progressively nudges the lens away from the drive element. Pulling the lens back again involves reversing the process: rapidly expanding the drive element so that it slips through the clamp, then slowing drawing the lens back in, one step at a time.

Why do it this way? Well, it’d certainly be quiet and it allows very fast movement, giving the lens possibly the fastest focusing we’ve ever seen in this class: when paired with the a7R II’s phase-detect AF system, autofocus is quick and precise. A single element able to move quickly back and forth in tiny steps lends itself well both to contrast detection focus in video as well as being able to reverse directions when subjects erratically switch between approaching and receding.

Adding a snap to aperture-by-wire

Another interesting design detail is the switch for engaging and disengaging the stepped, clicking aperture. A weather-sealed switch pushes a small, sprung ball bearing against a series of tiny teeth, to give tactile feedback as you rotate the aperture ring. However, no other mechanical connection is engaged: the aperture is entirely controlled by-wire, with a sensor detecting movement of the aperture ring and relaying it to the aperture motor.

Locked on place

The other major difference between the Canon and the Sony is the philosophy behind lens alignment. Where the Canon had a series of shims and adjustment screws to allow the different elements to be re-aligned, and re-centered, the Sony has most of its elements glued together in one giant module. This whole module then has three shims offering only a small degree of adjustment. LensRentals’ testing of its copies suggests this adjustment isn’t sufficient to give the consistency you might hope for.

Individual replacement parts are not available for after-market repair: the only option is to slot a whole new module in, with limited adjustment to ensure its alignment within the lens barrel. This approach means Sony has a good level of control over the alignment within each module but means the lens is harder and more expensive to service if it goes out of alignment or if the front element gets scratched.

In summary

The construction and adjustment isn’t quite as extensive as in the Canon but, as Cicala highlights: nor is it in most lenses. Instead it appears Sony has designed its lens so that it’s durable and everything is fixed in place, whereas Canon has built its lens to be tough but accepted that as a photojournalist’s workhorse, it’ll need to be beaten back into shape every now and again.

it’s clear, though, that Sony has built this lens to be tough: not only is each element individually positioned, rather than being spaced apart, relative to another, but Sony has included extensive amounts of weather sealing at every step of the design (just look at the size of the rubber gaskets, in the picture above). Cicala concludes: ‘This lens has the most rubber gaskets I’ve ever seen. The weather and dust resistance in the lens itself should be superb.’

Here’s a video showing how I created my own “air brush” system. It’s a quick solution for you when you are in a pinch! While I wouldn’t recommend it for long term use, or for detailed airbrushing, it’s a quick and easy way to make your own air brush effect when you need it! I also tried the Stampin’ Up markers and Bic Mark It with the air can, and was able to get great results, but the brush nibs on those pens means you have to hold it a little bit better, where the chisel tip on the copics was easier to hold to the tip….
