Panasonic Lumix 20mm Micro Four-Thirds lens

Micro Four-Thirds

State of the art.

A couple of years ago I wrote that the real digital revolution in photography gear would be fomented not by traditional manufacturers but rather by the new breed of companies specializing in electronics and modern design, unshackled by historical investments and conventions.

Never has this proved more true than with the Panasonic 20mm f/1.7 ‘standard’ lens for the G1/GH1/GF1 micro four-thirds camera range. As the excellent piece at DPReview discloses, this 40mm equivalent lens is simply state of the art, a superb marriage of hardware and corrective software design. I would go as far as to say that it is to digital what the 35mm SummicronM, in its aspherical final version, was to film. I used one of those for years and, suffice it to say, you could buy no fewer than seven of the Pannys for the ridiculous price asked for the Leica optic today, so it’s hard to complain that the Panasonic lens is expensive.

The new Panny lens peaks at f/4, just like the Leica Summicron of old (both in its 35mm and 50mm guises) and, unlike the kit zoom, does not include shake reduction. Perhaps the shake reduction on the Olympus EP1, which is built in to the body of that camera, works, but frankly the EP1 is such a poorly executed camera for street snaps (slow focus, awful shutter lag, no proper viewfinder, mediocre optics, etc. – a joke from such a great manufacturer) that it’s not like I will ever be trying it.

So why am I not rushing out to buy one? Well, I very much intended to when it was first announced but, frankly, I have become so enamored of the kit lens with its exceptionally useful 14-45mm (28-90mm on full frame) zoom range in a very small package that I no longer want to be burdened with the task of swapping lenses when snapping on the street. Or, for that matter, carrying more clutter. While f/1.7 is nice to have, the f/3.5-5.6 maximum on the kit lens is fine for my purposes, as I am not an available light maven. And the kit lens is so good I find that I am using it at or near full aperture nearly all the time, with the built in shake reduction adding 2-3 stops, effectively, in low light, making the effective aperture range more like f/1.4 to f/2.5. The only thing I miss is the shallower depth of field that a true f/1.7 offers, but the compromise more than works for me.

March 31, 2011 update: I ended up buying one of these and you can read about it here. I returned it on April 1, 2011, as this is one of the least competent street snapper lenses I have ever used – to add insult to injury the very slow autofocus comes with extreme flare, incorrect exposure on my G1 in auto mode and an inability to orient imported pictures properly in Lightroom. Other than that its great ….

Burning the late night oil.

G1, 24mm, f/6.3, 1/30, ISO 400

Spotted late evening in Carmel, CA.

The G1’s iISO feature (intelligent ISO) determined the ISO 400 setting, presumably predicated on using a shutter speed no slower than 1/30 to avoid camera shake at the 24mm focal length. I was using aperture priority and chose the f/6.3 setting. iISO seems to settle on shutter speeds no slower than 1/30 at medium focal lengths, unless the light is so poor that an even slower shutter speed is called for. At 24mm (48mm full frame equivalent) the 1/30th is like 1/125th with the two stop gain in shake reduction owing to the OIS feature built into the lens. I have the ISO limit set at 800 as at 1600 the image really starts to break up.

The bottom line is that iISO does an excellent job of mitigating camera shake by adjusting ISO, to the extent allowed or possible.

Lightroom

Aperture is dead in the water.

Having started serious volume digital photo processing with Apple’s Aperture and finally made the switch to Lightroom almost two years ago, the following data recently released by Adobe hardly surprise me:

Clearly, I’m not the only one making the move, especially if you take into account the large increase in Mac sales in the past few quarters. Forget the upper table – Aperture does not run on Windows so it’s not a fair comparison. The lower table is.

When did you last hear of a meaningful update to Aperture or see any advertising for the product?

Those still using Aperture should be getting worried and would do well to consult my earlier piece on abandoning that major stress source for Mac performance. Aperture is another orphan application which couldn’t handle the heat in the kitchen. It’s future is …. well, what future? Have you noticed how Aperture does not even support Panasonic G1/GH1/GF1 RAW file import – maybe the most signifiant camera design to hot the market in the past year? That makes me think it’s a dying application, starved of capital as Apple concentrates on making …. cell phones.

It bears repeating – the user interface in Lightroom is not only logical and linear, it actually makes photo processing fun. That’s not something I thought I would ever write. And you don’t lose track of originals or accidentally erase them, either.
