Panasonic Leica 15mm f/1.7 MFT lens

An interesting addition.

It’s not available in the US yet, though B&H already lists it:

The real comparison here for street snappers is the stellar Olympus 17mm f/1.8, which I have been using for a few months now. Regular readers will have noticed that the predominant gear byline for most of my recent street snaps published here is “Panny GX7, 17mm Zuiko” and the reasons are the same I noted in my original review. The fastest AF focus ever, unbelievable flare reistance into the sun, lovely color rendering and excellent optical quality at any aperture. The 17mm Zuiko is very much my “where have you been all my life?” lens.

So this new Panny-Leica optic has its work cut out in the competitive landscape. Fair, it’s a tad wider at 30mm FFE compared with 34mm FFE for the Oly and, truth be told, my brain is hard wired for 35mm after decades with a Leica M2 or M3 and a 35mm Summaron or Summicron attached.

But the point here is that it is heart warming to see so many lenses and makers in the MFT system – Panasonic, Olympus, Leica, Voigtländer with others like Bower/Rokinon joining the frey. And it’s ridiculous to argue that the $600 asked for the new 15mm optic is high. Have you priced Leica’s MF Summicron for the M body recently?

I was going to run a piece in late 2013 on the Panasonic GX7/Olympus Zuiko 17mm f/1.8 as the greatest street snapper combination yet, but decided to hold off until I had more experience with the outfit. Unless there is something very special indeed about the new Leica optic, expect to see that piece run in December, 2014.

Meanwhile, the hegemony enjoyed by Canon and Nikon in pro DSLR ‘flapping mirror/vast bulk and weight’ applications addresses an ever narrowing field of specialization. If you need very shallow depth of field and routinely print larger than 18″ x 24″, there’s still good reason to go with the big boys. But for everyone else, MFT solves. APS-C seems increasingly pointless to me – most of the bulk of FF and none of the pluses of MFT.

Conflicted advice? Hardly. I use a Nikon D3x/D2x and a host of legacy MF lenses, mainly because it’s fun and the investment is amortized. But light and jolly this gear is most certainly not.

The Computer History Museum – Part II

The modern era.

Part I is here.

Many of the rooms in the Museum address the modern era, which I think of as being anchored by the introduction of the two landmark home computers, the Apple ][ and the IBM Personal Computer. The Apple was more than I could afford so I bought the IBM PC in 1983 and it was modern in the sense that it used disk drives, albeit low capacity floppies, had a modem and could accept expansion cards.

But before that, in 1981 I splashed out $1,795 for the best computer I ever owned, the Osborne 1. Purportedly portable, it weighed 23 lbs.


My first computer. The Lee Felsenstein designed Osborne 1 of 1981.

The small CRT screen was supplemented with a $100 plug-in 10″ green on black one, the stock display being pretty much unreadable. Two things made this machine special. First, it was cheap by the standards of the day – the software alone came to the price of the machine if bought separately. Second, it came with a ton of said software. In addition to the lean and mean CP/M operating system, it included the Supercalc spreadsheet application (a clone of Visicalc, the first spreadsheet), Word Perfect for word processing, Basic and most importantly, Ashton Tate’s dBase II.

The Ozzy had 64KB (yes, 64KB) of memory, CP/M taking maybe 28KB of that, and as the applications were tightly written with much assembler code, things just zipped along. It never locked up – something Windows would fix for the ensuing decade of misery. If your spreadsheet or magnum opus was too large disk swapping would kick in, using the second of the two 360KB, one sided floppies. The other floppy drive was used to load the OS and app of choice, one at a time. This was before the days of graphics, so despite these limitations speed was not an issue. After a few months I added a 300 baud dial-up modem for the early days of the Internet. You can see one below the left hand floppy drive, above. It was slower than molasses.

Suffice it to say that after a few months use I was expert in word processing and spreadsheets, decent in Basic and a wiz in dBaseII. Disk swapping meant you could store pretty large databases on the floppies and the application was very competent indeed. It’s fair to say that I learned 75% of what I needed about computer use on the Ozzy, as things only got simpler down the road. The remaining 25% was Photoshop and related, a few years later. The practical knowledge gleaned from using the Ozzy was worth orders of magnitude what I paid for the machine.


The two floppy IBM PC – my second computer.

While the Ozzy was still pretty much a hobbyist machine, the IBM PC was polished and finished when first sold. Where the Ozzy had the feel of a garage build, the IBM PC was made to very high mechanical standards – over-engineered really and a bargain at $1,565. That’s $6-7,000 in today’s money. There was a costlier XT version with a 10MB hard drive, but that was more than I could afford. I added an orange on black 12″ display and a 9×9 pin Okidata dot matrix printer which jammed faster than a Catholic priest chasing an altar boy.

Working at Salomon Brothers on Wall Street at the time, a like machine arrived and sat gathering dust for several months before I pulled my finger out and wrote some handy Basic routines addressing security positions and valuations. The Ozzy had taught me well. Within a year there was one on every desk, all running Lotus 1-2-3.

It’s amazing to recall how slow the clock speed of the Intel 8088 CPU in the IBM PC was. Just 4.77 MHz, single core. I’m writing this on an upgraded 2009 Mac Pro whose twin CPUs run 24 virtual cores at 3.33GHz – some 700 times faster per core. But the modern machine, though it processes any sort of graphics and audio you can throw at it with aplomb, really is not much faster in real use. Back then, tight code was a requirement given the limited memory available. Now it’s an irrelevancy.

Moving on we came on the Game Room where Winston got absorbed in the many early consoles and game machines on display, not least the very capable Atari. There’s an early Pong machine on display and all it does is present two bats, one to each player, and a bouncing ball, which goes ‘pong’ when you hit it – not as easy as it seems. Many bars installed this at the time and many quarters were wasted by patrons playing this inane game.

Finally, Google has a couple of fine displays, one for Google Earth on five large LEDs:


Finding home using Google Earth.

Another lets you sit in one of the Google StreetView cars, atop which is mounted a nine lens camera – eight around and one to the sky:


Google sees all, whether you like it or not.

The remaining displays, replete with PDAs (PalmPilot, anyone?), cellphones and modern PCs, leave me cold. How excited can you get about cell phones, the original iPhone apart?

What is missing?

A room devoted to the sheer hilarity of the many predictions made about technology would do well to discourage speculating about anything further than a week out. Here are some of my special favorites – obviously Doofus must take pride of place here:

  • “There’s no chance that the iPhone is going to get any significant market share”. Steve Ballmer, Microsoft CEO (April 2007)
  • “There is no reason anyone would want a computer in their home”. Ken Olson, president Digital Equipment Corp (1977)
  • “Remote shopping, while entirely feasible, will flop.” Time Magazine (1966)
  • “The ˜telephone” has too many shortcomings to be seriously considered as a means of communication.” Western Union internal memo, 1876.
  • “I think there is a world market for maybe five computers.” Thomas Watson, chairman of IBM, 1943.
  • “The world potential market for copying machines is 5,000 at most.” IBM executives to the eventual founders of Xerox, 1959.

Compared to those the daily pap you see in the MSM about the stock market is supremely credible and accurate.


Winnie 4 years ago with the iPad1 – not making any predictions..

Dining:

After visiting the Googleplex down the road we drove back across the freeway on Shoreline Boulevard into the town center on Castro Street in Mountain View, a city which was virtually unknown until Google came along just 15 years ago, somewhat defying the Luddites’ conviction that technology destroys jobs. Now Castro Street is lined with chic restaurants and stores, including three (!) bookstores. You know, hard covers, paper, numbered pages and so on.

We had lunch at CrepeVine, which offers a bewildering array of crepes. It’s directly opposite Books, Inc.:


A bewildering array of crepes.

I went for the Tuscany with chicken on a savory crepe, whereas Winnie opted for a truly disgusting looking toasted cheese kids’ sandwich with fries. Pure glop. $20 for the lot and we sat on the sidewalk under heat lamps. My son was the youngest person there, amidst an algorithm of Googlers, and I the oldest. The distinction we brought to the assembly is that neither of us has a boss, nor ever will.


Hustle and bustle at lunch.

Sated, we chatted about our Museum visit and Winnie gave it a “Totally awesome” rating, a modern adaptation and corruption of the language of Shakespeare which translates to ‘Bloody Good’ in the mother tongue.


Totally Awesome! Winnie at the Crepevine.

The Computer History Museum is unreservedly recommended, even for Luddites.

4K displays – latest thoughts

Getting there.


Click the picture for the Seiki site.

A better graphics card:

In anticipation of eventually adding a 4K display, I have upgraded one of my Mac Pros, with an EVGA nVidia GTX680 2GB PC graphics card. The card fits in the #1 PCIe expansion slot, where its double width does not block any of the three other slots. This machine currently uses a $220 Seiki 32″ 1080p TV set as a display, running at 60Hz over HDMI. The ROM in the GTX680 has been flashed by the seller to allow display of the opening splash screen with the Apple logo and cog wheel on start/restart. This is not essential, but nice to have when doing an Option-Restart which will display all bootable drives on the screen. If you don’t miss the splash screen, buy a used PC GTX680, for under $300. It will work fine. You can flash this yourself if you are running Windows in BootCamp – I cannot as Windows is not permitted chez Pindelski, sanity trumping choice. I bought the flashed card used on eBay for $400, compared with $670 for a new ‘Made For Mac’ GTX680.

power cables attach to sockets on the backplane board.

The former GT430 compared with the GTX680:


A significant increase in performance. Call it five times as fast.


The new card reported in System Information.
Link speed is 5GT/s.

Don’t overdo it!

Along with the ATI Radeon 7950 (200 watts maximum), also available in a ‘Made For Mac’ variant, the GTX680 is the most powerful card available for the Mac Pro which does not risk overpowering the power feeds. The maximum power available to the card is 225 watts (75 watts on each of the two PCI cables and a further 75 watts from the PCIe slot), which compares with the maximum draw of 195 watts for the card. Cards which can draw more than the 225 watts available, and thus risk damage to the Mac Pro include (but are not limited to) the Radeon 7970, 7990, R9 280, R9 290, GTX580, GTX590, GTX690, GTX770, GTX780, GTX780 TI, and GTX Titan. If you propose using any of these hard, a separate power supply is indicated.

Sound over HDMI:

Additionally, OS X 10.9.2 broke sound over HDMI (thank you Mr. Cook – Apple’s Ballmer) but a smart person has posted the fix at MacRumors and you can find it here. Be sure to check my message (#68) in that thread if you run into problems. The kext (driver) provided by the original poster works fine and HDMI once again shows as a working choice in System Preferences->Sound, delivering sound over the HDMI cable to the TV’s built-in speakers.

The state of 4K displays:

Nine months ago I wrote about the early state of play regarding 4K displays, which offer 3840 x 2160 pixel definition. Until now, the highest pixel density available has generally been the 2560 x 1600 available in 30″ Dell Ultrasharps and in the discontinued 30″ Apple Cinema Display.

Things have moved along and there are now several choices of 4K display for the Mac Pro (2009/4,1 or 5,1 and later, and new Mac Pro) user:

  • Dell P2815Q 28″ using twisted nematic display technology – $700
  • Dell UP3214Q 32″ – LED – $2,500
  • Dell UP2414Q 24″ – LED(?) – $1,200
  • Sharp PN-K321 32″- LED – $3,100 or $3,500 from Apple for the foolish
  • Seiki SE39UY04 39″ – LED TV set – $500

For reasons attributable to the genius in charge at Apple, none of these will run OS X at the usual 60Hz which delivers smooth cursor motion. All run at 30Hz in OS X, whereas the first four will run Windows in BootCamp at a full 60Hz. Way to go, Timmy! Your OS runs Windows better than it does its own native apps while Apple touts the 4K capabilities of the new Mac Pro ….

The fifth, the 39″ Seiki TV, runs at 30Hz only in either OS X or Windows, owing to hardware limitations in the TV set.

So my Mac Pro is ready for 4K but which display to use? I’m not about to pay $2-3,000 for a display and the latest rumor has it that Seiki will be selling a revised version of their 39″ TV set in Q2/2014 for maybe $800, sporting 60Hz screen refresh rates. 39″ is huge – 2.1 times the display area of a 27″ display and at twice the definition, and 3.6 times the area of a 20.5″ display. If that happens, I should be seeing 4K here soon. 10.9.3 will be required to support 60Hz and it is in advanced beta test as I write.

There are issues with 4K implementation in OS X Mavericks, not least being very small font display at 4K definition. My proposed use is simply to display large realtime charts of stock market data (my day job) during working hours, so text size is not a key driver for my purpose. However, I will be testing the display with Lightroom and Photoshop and reporting my findings in due course. Color calibration with a colorimeter should not be an issue as the Seiki TV has extensive color adjustments built in, with more secret stuff in the Service Menu, which you can access by hitting Menu->0000 on any Seiki TV’s remote.

Cheap Arca plates

From Desmond.

One of the things which irritated me about the otherwise excellent Surui K-40X ball head for my old Linhof tripod was that the Arca plates for additional cameras (it comes with one) were overpriced at over $40 each.

I needed additional plates for my 350mm and 500mm Nikkors, each with lens mounted tripod fixtures, a clamp for my Manfrotto monopod, and a small plate for the Pansonic GX7, and was not about to be hosed down for overpriced pieces of alloy with simple, machined v-notches.

Shopping Amazon I chanced on the Desmond brand of knock-offs (a knock-off of a knock-off) at Amazon and proceeded to order the following:

The first two are for the Nikon D2x and the 350mm Nikkor. Hullo! $6.50 each! (The 500mm Reflex Nikkor already has an original, overpriced, $40+ Surui). The second row is for an Arca-compatible clamp for my monopod which sports an old Leitz ball & socket head (superb!), replacing the previous Manfrotto QR plate. And the last is for the GX7, a very small plate for a very small body.


The full-sized plate for the Nikon D3x/D2x


The clamp for the Leitz B&S head. Comes with a 3/8″ to 1/4″ reducer.


The camera plate for the Panasonic GX7.

All the plates come with a D-ring for the retaining screw as well as a generously sized slot which will accept a variety of coins for torquing down.

Reactions? All fit fine. The safety locking slot/button on the stock Surui clamp works perfectly.

And the lot costs about as much as one Surui ‘original’ knock-off. In fact I like the big camera plate so much I have replaced the Surui on my D3x with the Desmond, relegating the Surui plate to the less used D2x. Life is too short for all that screwing ….


On the Nikon D2x.


On the 300mm Nikkor.


On the Panny GX7 – small enough to be left in place.
The battery/SD card remain accessible, but
you can no longer flip up the LCD.

The Desmond plates have a 0.48″ wide dovetail at the broadest point, compared with 0.53″ for the Surui. This means that fewer turns are needed on the unlocking clamp on the ball head to release the camera – 0.75 turns of the locking knob for the Desmond compared with 2.75 turns for the Surui plate. Nice.

Nicely made and dirt cheap, what’s not to like?

Full frame bargains

From Canon.

One of the signal advances for photographers has been the continuous improvement in processing software. The enhanced capabilities for shadow recovery and highlight taming in products like Lightroom 4/5 (and doubtless in others like DxO, CaptureOne and Aperture – none of which I use, but competition always does its thing) give new life to old picture files.

Case in point, my first serious DSLR was the original Canon 5D (2006). When I pull up images from that body in LR5 they appear with an exclamation point lower right alerting me that an older version of LR was used to process them. Update those to the latest version (Develop Module->Settings->Process) and your images can enjoy the benefits of the latest in processing technology.

I have gone back and re-printed some of these and the results really are impressive.


The indoor pool at Hearst Castle.

The above 5D Mark I image has high dynamic range. Updating to the 2012 Process from the original 2003 in LR5 allows easy recovery of the shadows and taming of the highlights with the related sliders. A touch on the Noise slider takes out what ails the shadows. A quick click in the Lens Profile section has the 15mm Canon Fisheye image de-fished for a linear rendition, into the Print module and the 18″ x 24″ print will knock your socks off.

Sure, neither the original 5D or its ‘pro’ equivalent 1DS Mark II had sensor dust removal, but I can assure you that my Nikon D700 did and it was almost useless. You still had to clean the sensor with moist alcohol swabs, as I now do with my Nikon D3x. The price of a lightly used, amateur owned 5D or 1DS Mark II? How about $450 or $800? If there’s a better bargain for a photographer looking to make really large prints from full frame negatives I do not know of it. And you can forget the overpriced ‘red ring’ Canon ‘L’ lenses. The 15mm f/2.8 Fisheye (discontinued), the 35mm f/2 USM, the 50mm f/1.4 USM and the 85mmf/1.8 USM ‘cooking’ variants deliver all the quality you need, at bargain prices. Just avoid the cheap and nasty zooms if you are printing big. For web display any FF DSLR is overkill.


The exceptional Canon 1DS Mark II.

Nikon? There are no FF bargains yet. The D700, which has an excellent low noise sensor sells lightly used for a surprisingly high $1,300, the D3 (same sensor, pretty much) for $1,800.

New prices of the 5D and 1DS Mark II? How about $3,000 and $8,000, respectively? Do you really need the latest and greatest or would a small fraction of the extra money be better spent on a large format printer, paper, ink and some mounting supplies so you can really show your work for once?
