Electronic surprises in 2018

Motorcycles, Photography

Some great devices.

The digital world marches on and much as I fight the tide with a solid adherence to an analog, mechanical universe, there’s no denying that digital technology is superior in every way, despite having the personality and charisma of a washing machine.

One of the costliest additions to the digital household at the beginning of the year was a 65″ LG OLED TV. Thinner than an iPhone it starts very quickly, delivers blacks the likes of which were heretofore unobtainable on a television and, unsurprisingly, is reliable as a refrigerator. While I confess to being slightly discombobulated with the occasional exhortation on turn-on to update the operating system, the device is a delight to use. We are rapidly approaching the day where that 100″ projection screen setup I installed in the vineyard home will become affordable in a big screen TV. The price one year ago was $2,697. The set now retails for $2,349, a modest drop of 13% reflecting the difficulty of making fault free large OLED panels. And did I mention it’s thinner than an iPhone?


The 65″ LG OLED TV.

That big screen TV was accompanied by a pair of special electrostatic loudspeakers, as capable of rendering shoot-’em-up action as they are in plumbing the depths of Horowitz’s Steinway. There is a lot of overpriced trash in the high end speaker sector. Martin Logan has been around for ever and appears financially stable.


A very special loudspeaker – the Martin Logan ESL.

And because those electrostatic panels are not that good at moving the large volumes of air dictated by low bass notes, the main speakers are accompanied by the desirable adjunct of a powered sub-woofer.


The Martin Logan Dynamo 700 subwoofer. Low notes are rendered correctly.

But it’s always something and both the main speakers and sub-woofer demand lots of clean power so the Parasound stereo amplifier, 5 year warranty and all, joined the team:

This outfit has quickly become second nature, taken for granted like a good camera and lens.

And speaking of cameras and the analog world, what could be more analog than film? I blame two friends for my film rediscovery this year, the one a film fanatic and prof at CalTech, the other an AV technologist in Boston with a fine eye who sent me some rolls of Kodak’s Ektar. I went about the hardware discovery process in the best American tradition. I threw money at it. So I snapped up a Nikon FE, A Nikon N90S and a Nikon F100, to see which spoke to me loudest. The FE was lovely but I really missed AF as my eyes are not what they were. The N90S came in a lovely compact package but refused to speak to my old chipped MF Nikkors on those increasingly rare occasions where I brave manual focus. But the F100 proved to be the bee’s knees, a perfect melding of digital technology (AF, auto exposure) and film. Money? Film bodies are so inexpensive that after selling the FE and N90S I was but $150 out of pocket.


The finest film camera made. The Nikon F100.

Not least of the F100’s beauty is that the controls and layout are almost identical to those of the D700, Nikon’s first FF DSLR and one I reverted to after selling the big and clunky D3x. Sure the D3x delivered 24 sharp megapixels, but I really did not need those, any more than I needed the truck-like weight. The D700 boasts but 12 high quality megapixels and boy do they ever work.


The Nikon D700 – available for very little in mint condition.

Finally, long time readers will know that I am a confessed long time motorcycling addict. My 1975 BMW R90/6 is now in its 29th year with me and absent newer shocks remains pretty much in original condition, right down to the antique but perfectly capable mechanical points ignition. The sole nod the BMW makes to the electronic world is a couple of $1 relays to preclude frying of the wiring harness when the 120dB Italian FIAMM horns are worked to alert left-turning morons in cars that a two wheeled human being is headed their way.


My 1975 BMW R90/6. A product very much of the mechanical age, with awful instrument lighting.

But this year the miserably weak instrument lighting, a small sub-chassis containing a myriad of minuscule incandescent light bulbs prone to failure and hell to access for replacement, gave way to an LED harness. This was invented by a lady rider who had grown mightily frustrated with the constant failure of her stock lighting harness, not least the fact that if the generator bulb fails that it takes the whole ignition system with it. Who thought that up? Anyway, that frustrated lady rider happens to have a spouse who is expert in CAD/CAM and he came up with an LED bulb chassis which is a drop in replacement for the stock one, is so bright that I can finally, after 29 years, see my high beam indicator in bright sunlight, and which will certainly outlast me and the bike.


The stock and KatDash LED lighting harness for the BMW Airhead.

And while I am mixing analog and digital, you should know that both my tachometer and speedometer failed within weeks of one another at 63,000 miles, expertly repaired by the geniuses at Palo Alto Speedometer at considerable expense. At least I will not have to crack the instrument housing again. For all their charm and charisma, no one could accuse analog devices of coming with low maintenance costs.

iPhone you ask? Why yes, I was forced to upgrade my iPhone 6 by a felonious maker who made it so slow with software ‘upgrades’ as to be useless. I switched to a used iPhone 7 for a net cost of $300, thus denying said felon my money while reclaiming the lost speed at reasonable cost. No more new iPhones for me.

Nikon – a magnificent legacy

Cameras, Nikon bodies, Nikon lenses

The Nikon Museum in Tokyo.

Nikon honors its legacy in the extensive displays in the Nikon Museum. When Nikon abandoned the Zeiss Contax lens mount replacing it with the F mount in its first – and best – SLR, the peerless Nikon F, it was as much a statement of intent as it was an act of courage. The wisdom of that decision persists to this day when even the earliest F mount lenses can be mounted on the latest Nikon D850 DSLR.

Now with a new, wider mount in the Z6/Z7 mirrorless offerings, Nikon has finally begun to abandon the flapping mirror in favor of what is already acknowledged as the best EVF in the business, the one found in the new Z bodies.


A display of rangefinder bodies which preceded the Nikon F. The related lenses put Nikon on the map.

Leitz, Wetzlar used to be the owner of the legacy crown, snatched from it by Nikon with the Nikon F which saw the rangefinder Leica M bodies migrate from being workhorses to becoming silly Veblen goods. The working pro gives these not even a passing thought, no more than an enthusiastic driver thinks about Rolls Royces.


The Nikon F. The camera which changed everything. This camera did to the German
camera industry what Honda did to British motorcycles.

4mp is all you need

Technique

The lunacy of the pixel race.

These images are of the same subject with the two best lenses I own – the ‘pro’ Lumix 12-35mm at 25mm (50mm FFE) on the Panasonic GX7 and the Nikon D700 with the 50mm f/2 HC MF Nikkor. The GX7’s sensor is 16mp on 3/4 sq. in., the D700 has 12mp on its 1.5 sq. in. sensor. Both at 400 ISO and f/5.6.

The image below enlarges the center 40x, so a 40” x 60” print. Note the greater warmth of the Nikkor optic. To properly display focal length in the EXIF data I have installed a CPU in the Nikkor lens, which has nothing to do with its optical quality. No extra sharpening – just the default of 25 in Lightroom, no other processing:

These images display maybe 1 mp of the sensors’ pixel counts.

In the next image I have increased the GX7 sharpening from LR’s default of 25 to 70. The Nikon image is unchanged, using default sharpening:

The results are indistinguishable as regards definition.

Here you can compare the shadow details – GX7 at left. The D700 has one of the best sensors for rendering shadows in the business:

The results are again indistinguishable.

The madness of the sensor pixel race, with FF sensors now approaching 50mp, dictates that users upgrade their lenses as all the ‘faults’ of older optics are now on display when pixel peeping. The reality is that no one makes 40″ x 60″ prints and that users would be better off sticking with modest sized sensors and old lenses. The 50mm f/2 HC Nikkor used in the above dates from 1973 and can be found in mint condition for $50. A mint Nikon D700 with low shutter actuations can be had for $450 or less. And you will not have to wait all day for the images to render in Lightroom owing to the modest file sizes.

4mp is all you need.

Nikkor 28-105mm f/3.5-4.5D AF lens

Nikon lenses

A decent walkabout optic.

The heart warming facts about Nikon’s AFD zoom optics is not only that many choices exist but also that many are insanely inexpensive in mint, used condition.

My mint copy of the 28-105mm f/3.5-4.5 ran me but $78 plus $7 to Amazon for a 62mm UV protective filter. I did not bother getting a lens hood as the one for this lens is huge and mostly useless.

The rational ‘walkabout’ comparison is the 24-120mm f/3.5-5.6 IF lens which adds internal focusing for a smoother feel and extends more at both ends. I have been using the 24-120mm on my Nikon F100 with Ektar film with considerable success. If there’s a complaint it’s the generous dollops of distortion, barrel at the wide end and pincushion at the long. This needs correcting in LR with architectural subjects, a pain but not hard to do.



At their widest settings. Note that the zoom rings work in opposite directions.


At the longest focal lengths.


So how does the 28-105mm differ? Bulk and weight are much the same, the zoom rings displays a tad more stiction owing to the traditional design, the optic is faster at the long end by one stop and adds a handy macro feature.

Here are test images – you can compare with those from the 24-120mm f/3.5-5.6 by clicking here.



At 28mm, f/3.5, center and edge.


At 28mm, f/8, center and edge.


At 50mm, f/4, center and edge.


At 50mm, f/8, center and edge.


At 105mm, f/4.5, center and edge.


At 105mm, f/8, center and edge.


In summary edge performance at the wide end is ghastly at full aperture; you need to stop down to f/8 to make it useable. The 24-120mm optic is far better in this regard. The edges from the 28-105mm get progressively better as the focal length increases. Whereas the 24-120mm lens shows chromatic aberration (easily fixed in LR) the 28-105mm has none. Not published here, distortion characteristics disclose that the 28-105 shows mild barrel distortion at 28mm, disappearing at 50mm or longer. That is much better than the 24-120 which barrels greatly at 24mm and pincushions north of 50mm. Neither optic does a particularly good job of rendering out-of-focus areas, both yielding results that are too ‘busy’ for my taste. The 28-105mm lens shows no light fall off at the edges at any aperture or focal length. I have found that the later lens correction profile in LR for the 28-105mm f/3.5-4.5 G VR optic (the one with no aperture ring) works well with this earlier AF D lens.

Handling of both optics on the D700 DSLR and F100 film SLR is excellent. They balance well, zoom rings lack any gritty feel, AF is as fast as you need for all but sports subjects and as I always use aperture priority with aperture control transferred to the lens, the aperture ring on the 28-105mm is easier to access as the lens is less steeply pyramided at that location, making the ring more accessible. Not a big deal in practice.

The macro range on the 28-105mm is accessed by setting the focal length between 50 and 105mm and focus between infinity and 0.5 feet. The switch on the barrel is flipped and you get a very handy macro lens with a focal length range of 50-105mm. The long focal length setting is especially handy as it allows better clearance between the front of the lens and the subject. This is the closest I could get at 105mm:




The magnification ratio computes to 1/4 life size.

Sharpness, even at f/4.5 in the macro range, is excellent – fully useable.

Conclusion: If you need 24mm (which is much wider than 28mm) and useable edge performance near full aperture at the wide end, the 24-120mm is the better choice. If you prefer a minimum of post-processing to remove distortion the 28-105mm is to be preferred. The construction quality and material choices (more plastic) of the 28-105mm are lower but hardly a deal breaker and the macro feature is both useable and the optics excellent. Weights of the two lenses with filters are 16oz for the 28-105mm and 20 oz for the 24-120mm.

It’s a nice choice to have to make with each lens selling for well under $100. I have both!

Apple discards the college business

Macintosh

Silly-priced new MacBook Air.

Apple just announced the new MacBook Air and it’s priced at an over-the-top $1200 for the base model with a 13.3″ display.

You will not be seeing this much more:

Yes, this silly-priced MacBook Air confirms that Apple is strictly in the Veblen Goods market, where a premium price is seen as attractive, a low one as a disincentive to conspicuous consumption.

Consider: Wireless ear bud speakers at $120. Cellphones starting at $800 + tax + annual service contracts. The Apple Pencil to draw on your iPad at $100. All commanding 50% profit margins because someone has to pay for that ridiculous over-the-top flying saucer HQ:


Hubris. The Apple HQ building in Cupertino.

I’m writing this on a 2010 Mac Pro tower. In its faultless 365/24/7 life it has had one upgrade of GPU, CPU, RAM and SSD storage. I expect it to continue to deliver fault free daily performance for another decade, at 70% of the speed of the latest throwaway machines. When parts fail – and they seldom do – they are easily replaced with a screwdriver or two and readily available. The chassis design dates from 2006.

My MacBook Air is the last 11″ 2015 model made. I would upgrade this $800 machine annually as, with associated tax benefits, the upgrades were free. Then the 11″ was discontinued never to appear again. It weighs just 2.38lbs and is a handy portable companion. At 11″ a costly ‘Retina Display’ would be money wasted. It’s the perfect traveling machine whether for college student or businessman. But you can no longer buy it new. So now the aspiring student will buy a Chromebook with comparable specs to the new MacBook Air for, what, $450?

In a decade Apple has abandoned its core constituency, the pro A/V market. It has abandoned college students and the impecunious. And now it sells ridiculously overpriced, glass-backed, fragile cell phones for $1000 and up.

Strange business model for the coming recession.

Strategy? Given that technology changes at the margin for desktops, laptops, tablets and cellphones are very slow, I’m increasingly focused on upgrading to 2-3 year old tech, as I did in moving from an iPhone6 to an iPhone7 for a modest $300 net a few weeks back. No $1000 cellphones for me. I get 80% of current performance for 30% of the cost. That solves.
