Film, or Foveon ?

fish, or fowl?

in Sigma , Wednesday, January 06, 2016

Ah, the eternal quandary of the dilettante art photographer: film, or digital ? And if digital, which kind of digital ?  For many, the ultimate expression of film in these End Days is Kodak Portra 400, with its oh so aesthetic transparent, lucid, indeed filmic quality. Or to put it another way, washed out. And that description is not exactly unreminiscent of the way Sigma Foveon digital sensors paint the world. So, which is “better” ? The two examples here offer no conclusion, are not a test, and make nothing other than an observation.  And they’re taken with completely different lenses, so obviously the framing and viewpoint are quite different (the sign on the wall at the left of the second photo can be seen on the right of the first, beneath the stairs).  But the scene, lighting and time of day are the same.

The first, on Portra 400 120 roll film, was taken using my Voigtländer Bessa III (aka Fuji GF670). It has an 80mm lens, so near enough 50mm in old money equivalence. It’s probably the last (serious) medium format film camera ever to be designed, and it’s probably the best fixed lens MF rangefinder ever. The rendering of the Porta 400 film was entrusted to Silverfast’s NegaFix tool, scanned at 5300dpi on the OpticFilm, which at this setting easily resolves grain.

The second was taken using the quite remarkable (in several senses of the word) Sigma DP0 Quattro.  This has a Foveon Quattro sensor producing a file roughly equivalent, so they say, to a standard 39Mpix sensor. Which is quite big enough. More to the point, it produces absolutely gorgeous, natural, transparent, lucid, indeed filmic colours. In my opinion, anyway. In this case the lens is a highly corrected, good enough for architecture, 14mm, which is near enough to 21mm in old money.

So which is best ? I don’t know. I’m happy with both. They don’t call me Indecisive Dave for nothing, you know. One might expect digital to be more convenient than film, but Sigma levelled that one with a (ahem) fabulous piece of mandatory software called Sigma Photo Pro. Of course, I could also have compare with my standard, sensible Olympus digital camera. But there’s no fun in being sensible.

The Digital XPan ?

it just could be…

in Sigma , Thursday, December 03, 2015

Well, it’s here. The (maybe, possibly) “Digital XPan”. As I mentioned yesterday, I found that Amazon Germany was selling the Sigma DP0 Viewfinder kit for €780, if I followed an advertising link on an external site.  Going direct to Amazon, it was listed at €1000. Very strange, but I grabbed the opportunity, and they delivered. And it arrived this afternoon, and as soon as I could charge up the battery, I managed to escape from work for 15 minutes and took a couple of test shots, using the 21:9 aspect ratio.

The camera has a very unusual shape, but I find it quite nice to hold. It’s built like a tank, like the Merrills, but perhaps with a touch more elegance. The manual is totally unnecessary: the controls and menu on the Sigma are second to none, and the QS “Quick Select” button brings up a page which is even improved on the Merrill version.  I accidentally shot at ISO800, which would have been a disaster on the Merrills, but it’s ok here. The Foveon colours are as delicate and realistic as ever.

So, is it an approximation to a digital XPan? My very, very, first impression is that it might just be.

The Margin

avoiding the easy option

in Sigma , Thursday, November 19, 2015

This is a bit of a geeky post, but whatever. I’ve always been attracted to the more marginal aspects of whatever topic I pursue. Probably because the margins are less crowded, and I don’t have to talk to people. Photography is no exception. I’ve never owned a Nikon or Canon DSLR, although my earliest film SLRs were Canons, initially “borrowed” from my father. In the digital world I backed the Olympus horse early on, and have only ever owned Olympus interchangeable lens cameras. These days they’re getting uncomfortably popular, but I found the solution to that by settling on the black sheep PEN E-P5 rather than the much more popular (rightly so) OM-D series. Oh, I can rationalise my choices, no problem.

But my choice of the less popular range of what is still a marginal brand is totally overshadowed by what could really be my favourite cameras ever - and due to a eccentric decision by an eccentric, loss making wing of an eccentric company, it is cameras, plural - the Sigma Merrills. I’ve got two of these fantastic (in every sense of the word) devices, the DP2M and DP3M, with, respectively, equivalent 50mm and 75mm lenses. These cameras are the essence of the best in Japanese culture, but they also exhibit some of the weaknesses of small companies. Sigma is a private company run by enthusiasts for the love of photography and fine optical craftsmanship. They manage to turn a profit, too, and recently some of their lenses have been favourably compared to the best of Zeiss, and under a quarter of the price.  The lenses which are bolted on the front of these strange little “Merrill” boxes are exquisite. As, in my opinion, are the boxes.

The Merrill cameras (there are 3, but I don’t own the 28mm DP1) produce absolutely stunning output. The colour, the liquidity, the depth, the detail all remind me of the very best of slide film, only without the ultra narrow dynamic range and total lack of exposure latitude. Unfortunately, they also share the dislike of slide film of anything over 400 ASA (on a good day).

The handling is a mix of excellent and appalling. The excellent part is the electronic and physical control: the buttons, dials and menu work together to produce the smoothest, most intuitive user interface I’ve ever encountered on a camera, or indeed any other device. But then comes the rest: the camera itself is basically a rectangular box with a lens bolted on the front. It’s a very solidly constructed box, but it’s not terribly comfortable to hold. In particular the DP3M feels very unbalanced, with its relatively large, heavy lens. But the worst part is the viewfinder, or rather the lack of one. Sigma do sell optical viewfinders. I have one on the DP2M, and a Voigtlander viewfinder on the DP3M. But both offer approximate framing, and of course no readout or preview of any kind. The focus acquisition light is visible while looking through the viewfinder, but you have no idea what it has locked on to. But anyway, since there are only 9 AF points, all quite closely clustered in the middle of the frame, so actually it doesn’t much matter.

The LCD is ok, quite good actually, but my eyesight, while ok, is no longer good enough at close range to use a screen for focussing without glasses, and since I only use glasses for reading, it gets really, really awkward. Fine on a tripod, of course, but otherwise a total pain. Also, for me accurate framing is important - composition is maybe one thing I’m not too bad at, and for me it’s a very instinctive thing. Getting the framing right in camera is a major contribution to my enjoyment of photography - it’s a subconscious thing, I don’t make a big deal out of it, but when I can’t quite get connected in that way it’s very frustrating. And the Merrills really, really get in my way in that respect.

Which, ultimately, is why they spend a lot of time on the shelf.  But when I do decide to take them out, and they get all their many, chaotic ducks in a row, and they don’t decide to produce totally haywire, irrecoverable white balance interpretations, they astonish and delight me every time.  When the time finally comes to drop film, they’ll be waiting.
