Macro lenses

A brief personal history.

This piece addresses macro lenses – those which provide significant image scale when focused close. Regard this as a teaser for the unfolding story of my macro photography experience.

In Themes have their uses I ruminated on the need for themes – goals if you like – in your photography, if quality results were to be the result. After thinking more about it, I decided to do something pretty foreign, photographically, (God knows, I am foreign enough ethnically) to my way of working. So somehow the idea of a series of macro photographs came to mind.

The earliest macro optic I recall knowledge of, as a teenager, is the Kilfitt Macro Kilar. It was for 35mm cameras and went to half or full life size, depending on the model. Given that it was 40mm in focal length, that would have made for pretty tight clearance between subject and lens, making lighting tricky, but it was beautifully made and an original idea. I don’t know, but I’ll bet the aperture was manually set or pre-set, so it must have been a real handful in use. But Kilfitt had a reputation for great optics. Famous bird photographer Eric Hosking frequently used a 400mm Kilfitt Tele-Kilar on his Contarex. A rare and costly beast, Kilfitt was known (like Novoflex) for making adapters for a wide range of cameras.

Many Alpa SLRs, beautifully made in Switzerland, came with Kilfitt lenses, so the name has a long and storied tradition of providing optics to the best. Others came with Swiss Kern lenses, most famously the 50mm f/1.9 Macro Switar which focused down to some 7 inches, so maybe 1:8. Gorgeous Swiss engineering, it had the coolest depth of field indicators – colored dots would show up on the barrel as the focus was changed. I can’t swear to this but I think the lens also opened its diaphragm as you focused closer. Optical laws dictate, after all, that at 1:1 a lens loses 2 stops of effective aperture, owing to the illumination drop off in the much extended optic, before light rays strike the film or sensor. Zeiss Ikon conferred this same feature – a piece of mechanical engineering genius – upon several of its lenses for the Contarex, most of which focused especially close, if not in the macro range.


Kern Macro-Switar

Macro range? Choose your definition. For me it’s where I start seeing things I otherwise missed, so I suppose 1:4 and larger.

The first macro lens I handled was a Nikon Micro-Nikkor (never did understand why it wasn’t named a macro-Nikkor) for the Nikon F SLR. It handled well and was made in the days when lens barrels were still metal rather than plastic. That feels good even though plastic makes far more sense when it comes to cost and impact resistance. Independent tests at the time raved about it. If I recall, it focused down to half-life size (1:2) and a 25mm extension tube got you to life size, or 1:1. By all accounts it was a decent all rounder, boasted a speedy f/3.5 aperture and decent resolution at infinity, with minimal field curvature.

The first really close focusing lens I owned – hard to call it a macro – was the Corfield 45mm Lumax on my Periflex 2. While the camera accepted Leica rangefinder screw thread lenses, it dispensed with the usual cam coupled rangefinder mechanism, opting instead for a small drop down mirror, like an inverted periscope. This, through a separate eyepiece, provided a strongly magnified (if upside down) image of the center of the point of view. Great for focusing but there was no way on earth you could frame accurately at close distances, and the lens focused down to some nine inches. Nice idea though, and nicely made in Britain.

After that the closest I got to anything was using the 50mm Dual Range Summicron with those funky clip on eyeglasses for the Leica M. That got you down to some 19.5 inches – close but hardly macro. No mean feat with a rangefinder body, though, especially when you realize that correct framing was maintained all the way to the closest focusing distance. To compensate for the extra extension in the helix, Leitz mounted the lens head in a truly massive, brass base. The eyeglasses clipped to the top of the lens and failsafes ensured you could only use them in the close-up range and that you also had to use them to get into the close-up range.

Macro lenses have changed quite a bit since the above and are now easier to use than ever, as my forthcoming pieces on my experiences will show.

Easy birds

The low stress way.

I doubt there’s a bird I don’t like. Even the turkey vultures which call this area home, with a face only a mother could love, once on the wing are a thing of beauty.

The other day on our daily ramble, Bert the Border Terrier and I observed a red tailed hawk being mugged by two crows and a California Blue Jay. The jay actually landed on the hawk’s back, in mid-air, and gave him one almighty peck. He came out of the sun, rear three quarters and high, like a Spitfire in days gone by. The evil intruder promptly exited stage left. Just like in days gone by.

The little incident (I don’t carry the 5D with a 400mm lens on our walks, so no picture!) renewed my interest of snapping some action at one of the several bird boxes scattered around the estate, so being a lazy bugger, I set the 5D up with that old stand-by, the Vivitar 283 flashgun, together with that sweet little wireless remote.

Now I wasn’t about to hang about outside while the birds obliged me, so I left the whole thing high upon the old Linhof tripod and repaired to the kitchen, to watch things with those Trinovids, wireless transmitter in hand. True, real pros would have built a blind complete with air conditioning, but I’m a simple fellow at heart and it took the residents of the box some five minutes to return to business as usual. In fact, ten minutes later the bluebirds were using the 5D as a handy perch!

Flash was essential to light the shaded area, and the 5D’s less than stellar shortest flash sync shutter speed meant that a short light duration was called for. The 5D was at 1/180th, but the flash is no more than 1/1000 second in duration and that prevails in this instance. So motion blur is simply not an issue, precarious as the Linhof may look at maximum height. The chair in the picture was required as I am shorter than Michael Jordan.

Now while I may be a proud owner of signed copy of ‘An Eye for a Bird’ by the great Eric Hosking, one of the finest bird photographers ever, I have long known that I am simply not going to challenge the best of the best in this genre; but a few happy snaps make the realization easier to live with. On the other hand, given that his famous owl picture was taken by the bird as it flew through a light trigger, I can honestly say I worked harder than Hosking did on this one – I was the one who pushed the button.

These are small birds – the above snap is from one half the original even though the 400mm Canon lens was at its closest focusing distance, so it’s as if I was using an 800mm lens!


Nest building time. Same data as above.

And if you really believe that good photos can be taken with lousy gear, this is an example where only the best equipment could do the subject justice. Time to get the Rot out of your thinking.

Venus

No, not the planet.

Everyone knows this one:


Botticelli. Venus, 1486. Uffizi, Florence.

And here’s today’s version:


Towel advertisement, 2008

Maybe not as powerful a rendition as with that Raphael but a good effort nonetheless, the towel replacing the hair. Notice how the towel has been cleverly sculpted to imitate the shell in the original.

And if you are wondering where you saw that backdrop before, look no further than Hearst Castle’s pool:

Enjoying processing

Hard to believe, really.

I confess that the two words in the title of this piece are ones I would never have seen writing together. To me processing is simply a mechanical step that stands between the snap and its realization. A necessary if boring interlude which should be made as fast and automated as possible to let the picture show itself to the world.

If the increasingly rapacious hardware needs of every latest version of Aperture saw me abandon the product rather than spend more money on newer, faster computers seemingly every six months, then I can only report that my first few months with Lightroom have been nothing short of bliss. Relatively speaking, that is. I still hate to process but now I don’t have the endless frustrations of spinning beach balls and lost originals that were becoming Aperture’s specialty.

First, Lightroom runs happily even on our ancient G4 iMac and second, it simply cooks on my current bottom-of-the-line MacBook (1.83gHz C2D, 2gB RAM). Second, while the interface may lack the polish of Aperture’s, who cares? You no longer need Aperture’s pretty screens to distract you while you wait for the beach ball to disappear. In Lightroom you are already three snaps down the road of production and output. In other words, Lightroom is an industrial grade tool for users who need fast, reliable throughput.

Even round trips to Photoshop are not that bad. Once CS2 is loaded (it takes 30 seconds on the MacBook as it’s running in Rosetta PPC emulation mode) a round trip to take advantage of special features not currently available in Lightroom takes a minute or so. Mostly this is to use ImageAlign or the Transform function to correct skewed and leaning verticals. Other than that, pretty much everything I need to fix a picture is in Lightroom, and I would hope that distortion correction will be added to the next full version of Lightroom in a few months.

A related benefit is the easy ability to craft import and processing presets – nothing more than one click settings which confer a bunch of preferred adjustments on your image, with full preview and undo abilities. I should add that I use RAW exclusively for my source images, whether from the 5D or LX-1.

So I’m not about to say processing is fun, but Lightroom simply makes this step as painless as anything since Polaroid gave the world instant snaps.

This building in San Francisco’s charming North Beach neighborhood is being patched up but all I could see were rays of light falling on the wall. Plus, of course, a touch of Bonnard in that strangely inclined table.
