  1. Which to choose, the 135 or 150, is objectively unanswerable. It is as

    if you were asking which is better, popcorn with or without butter.

    However, I do think it is easier to make useful comparisons of lenses

    at one focal length, say 135. Michael Davies posted a comparison chart

    at this web site for 4 x 5 lenses. The chart shows that Rodenstock

    makes a 135 Sironar N that receives 40.5 mm size filters, while the

    Apo-Sironar S uses 49 mm filters. I understand that filters in the

    latter size are far more likely to be in stock. Moreover, step down

    rings from 82, 67, etc to 49 mm are more readily available. I am

    uncertain but I believe that the Rodenstock Apo-Sironar S has slightly

    more coverage than all or most of the other 135 mm brand lenses. See

    Davies chart. I believe that the Apo Sironar S has the reputation of

    being the sharpest lens that Rodenstock makes, although it is one of

    the least costly compared to other Apo Sironar S lenses. Only the 135,

    not the 150, is considered a wide normal. Used with a roll film 6 x 7

    or 6 x 9 back, the 135 can serve as a normal lens and allow tremendous

    shift capability. You can get further specifics from the distributor

    rep, Bob Salomon, at Salomon.hpmarketing.com or something like

    that..................................................................

  2. Johnson was not using the latest super model version of the Better

    Light 4 x 5 insert that increases the file size from 140 MB to over

    300 MB. According to an ad in the Nov/Dec 2001 View camera magazine

    the manufacturer Better Light claims that the clarity and detail of

    the current digital image supermodel back surpasses that captured with

    8 x 10 film. At its website, www.betterlight.com, the manufacturer

    describes the new supermodel allows images with up to 9000 x 15,000

    pixels. The Sinar HR-Sinarcam was also discussed in the Nov/Dec 2001

    issue of View Camera. It can provide 450 MB files with 75,000,00�

    pixels. The author states that the digital back enhances his

    productivity. ........... ...........................................

    I hope that you get the picture.........................

  3. I eliminated this recurring problem of two negatives ending up in the

    same slot by using the slotted separator and clipping it into place

    after all of the negatives have been inserted. Without the separator

    and clip, agitation tends to dislodge the negatives resulting in the

    problem you encountered. To speed up outflow, I do just what Baxter

    describes. When he refers to loosening the threaded cap on the funnel

    on the upended tank, he means only part way, so that no light leakage

    occurs............................................

  4. Years ago I read of Land demonstrating color images with two black and

    white transparencies projected simutaneously on the screen, each

    transparency taken from the same camera in the same location, no

    chanmges made other than switching filters, one projector with the

    same color filter mounted on the lens as was used when taking the

    original transparency placed in that projector, and the other

    projector without the color filter used to take that image. So much

    time has gone by that pehaps I am mistaken exactly how he did it. As I

    recall, it did not matter which two color filters were used, so long

    as they were of distinct colors....................................

  5. Contemporary creativity can be found in images that are notable for

    the unexpected composition, hues, light or shadow -- be it a Monet or

    a representation of what a person sees who is high on methamphetamine.

    Ansel, Edward, Brett, Eliot, Sexton, Muench, Dykinga, and Walker are

    notable for their exploitation of composition, light and shadows.

    Creative artists make something out of nothing. They show something

    surprising in the very ordinary. They might choose, for example, the

    textured surface of a painted concrete wall with saturated blue hues,

    a large intensely red stone among a bed of dull gray pebbles, or

    yellow markings conspicuously located on a very black asphalt concrete

    pavement, as was done by Ron Lussier's wonderful work at

    www.lens

  7. Robert White UL webpage shows the Fuji Quickchange. It is claimed that

    the design overcomes the problems of jamming associated with the

    Graphmatic. It accepts standard 4 x 5 films, not Quickload or

    Readyload. I would appreciate any comments you have about this

    accessory. xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx

  8. Bob says the Technikardan. He did not give the nod to the more

    expensive Master Technika or its predecessors. This serves no stinking

    self-interest. So how is it that Bob genuinely sees the Technikardan

    faster or easier than the MT? Let me speculate. The MT weighs slightly

    less, is more compact, is more readily folded and unfolded, has a

    clamshell built in protector for the bellows, can be folded with a 135

    mm lens in place that lies protected within the folded shell,travels

    better in a backpack, and is favored by many landscape photographers.

    Bob must have seen something in the Technikardan that outweighs these

    advantages. With the Technikardan, but not the MT, you have to change

    to a bellows bag to use wide angle lens, but you are not bothered by

    the flat bed that has to be dropped to ensure an unimpeded angle of

    view. With the Technikardan, you have independent controls for lens

    tilt and shift; very few flatbed cameras offer the same ease of use. I

    do not know whether the MT has this feature. With the Technikardan,

    you have a much longer bellows than the MT, easing infinity and

    closeup focusing with double agent 210 and 300 process lenses. The

    Technikardan provides center axis focusing, without the base tilt

    available with the MT. A lot of photographers find center axis

    focusing easier than base tilt; others prefer base tilt. Sure there

    are much lighter wooden cameras--some less than 4 lbs, but how many

    are as stable, have an extension of about 19.5 inches for long lenses,

    and provide as much ease of use with wide angle lenses, as does the

    Technikardan. Both TK and MT cameras can be easily equipped with lens

    compendiums (shades) supported by the camera body. The small size

    Technika/Wista lens boards are great for backpacking. Bob's preference

    is not isolated. Take a look at prior reviews of the Technikardan at

    this website, The majority of contributors (especially those with

    architectural interests) have given the nod to the Technikardan over

    the MT. I understand that former Ansel Adams assistant John Sexton

    owns and uses both and has written a published review highly praisng

    the Technikardan. A recent article in View camera magazine a few years

    ago -- I forget the author -- highly praised the MT. Several

    photography books by famed photographers David Muench and John Fielder

    mention their preference for the Linhof flat bed cameras for field

    photography. When ease of use encompasses scaling up to 5 x 7 or 8 x

    10 through use of adapters, then Canham, Sinar and Arca Swiss, and

    several other full system camera manufacturers, have an advantage, by

    selling larger format adapters. The adapters are quite expensive; the

    chief advantage is economizing space, especially when traveling.

    Bwfore committing to Linhof, I recommend that you look at Sinar,

  9. The vast majority of View Camera issues are superbly laid out. I hope

    that you continue with this high level of performance. Am I in error

    to say that yours is the only magazine that includes portfolios and

    interviews of large format women photographers? Certainly your

    magazine deserves commendation for the even-handedness with which it

    features women photographers. I notice that several women responded to

    your question on this webpage, which is almost unheard of at this

    website. I like the fact that you do discuss the photographers

    attitudes and the problem solving required to take the images

    displayed in the magazine, and I hope this practice continues. You

    invariably do this when you write articles for the pubication. It is

    the interplay between image and text that made Ansel's books on

    photography so helpful. I am of the impression that your magazine is

    largely devoted to American photographers. It would be satisfying to

    me if more were disclosed about the portfolios and commentary of the

    European or Asia large format landscape photographers. If there was

    any area in which your magazine has a shortcoming, it would be the

    unimaginative, strike that, awful advertisements by a few of the

    equipment manufacturers, in obvious need of input from a graphic

    artist. Overall I am content with your magazine as is but see no

    copellig reason why should not experiment

  10. Combine any wide angle (e.g. 75 mm lens, using center gradient

    filter) with lens shift; the wider the lens, the greater the lens

    shift, and the closer you position the camera to the ground, the

    greater the foreground emphasis (and elongation) and the greater the

    lens axis or film plane tilt needed to bring near and far into focus.

    Linhof has an instruction book that illustrates these techniques.

    Take a look at David Muench or Jack Dykinga webpages to see how these

    techniques are used by masters of far/near composition.

  11. One way to meet others with similar large format landscape interests

    would be set up or attend a weekend seminar, with instruction provided

    by a professional photographer. The seminars could be held near a

    location particularly appealing to the instructor. Lodging might be

    provided at a youth hostel. Attendees could be provided lists of

    lodging available in the area, with each attendee responsible for

    obtaining his or her own lodging. By searchig the web you can numerous

    workshops

  12. No one has made a strong or compelling case regarding the value of the

    changes in the TK45S. The owners of the older version uniformly praise

    it as being lighter and more compact. One contributor said that the

    TK45 has slightly longer extension than its successor TK45S, a comment

    that I suspect is a case of bellows envy. Some contributors mentioned

    experiencing the older version slipping out of adjustment when

    weighted down by the Polaroid back, but presented no evidence that

    this was due to the TK45 design or widespread. I have to acknowledge

    that I have experienced the same problem of slippage, especially when

    inserting a Polarid back. I thought it might be due to same grime or

    other lubricant accumulating between the surfaces that are pressed

    together to inhibit movement after I have set the levers. Alternately

    I suspect that maybe some spring had weakened with time -- the camera

    is nearly 12 years old and shows wear and tear. Bob implied that the

    event was rare, unexpected, likely easily remedied, and not a

    recognized design flaw. I am curious to know what is the corrective

    action that needs to be taken with the TK45 that has a slippage

    problem. I find it difficult to understand how the average user would

    find the indents on the TK45S preferable to degree markings, but as an

    expert, Linhof probably did verify this. I would assume that Linhof

    designed enhanced crashproof resistance of the TK45S to deformation in

    a quest for engineerng perfection. Our readership can reveal whether

    deformation of the TK45 has been a common problem. I experienced this

    deformation after my camera crashed to the ground off a cliff. I sent

    it to Marflex, Marflex fixed the problem, and I remain a happy camper.

    I would appreciate some contribution by Bob as to what is the nature

    of the problem and how it arises, that led to enhanced strengthening

    of the standards on the TK45S and decision to put in

    indents.................................................Regards,

    David.....

  13. I erred in saying that if you buy the TK 45, all you have is the 4 x 5

    format. I forgot about the fact that Arca and TK 4 x 5 cameras can be

    used with roll film backs, allowing 6 x 12, 6 x 7, 6 x 6, and 6 x 4.5

    formats, and Polaroid 545 & 545i film holders, with Polaroid films'

    unique dimensions. When lens shifts are used with these smaller

    formats, you will encounter more situations where you will not see any

    light dropoff, that otherwise might occur with the 4 x 5 film format.

    Thus, you will more frequently not have to use the center filters that

    will involve a loss of 2 f-stops. I do not know how much lens shift is

    required before any light dropoff is noticeable with the XL 110

    lens--the wider the coverage of the lens, the less likely you will see

    light drop with lens shifts. Light drop off is very noticeable for 4 x

    5 format with shifting of the Rodenstock 115 mm lens. Have you checked

    the price for the Rodenstock 82 mm center filter for that lens?

    Similarly, if you adopt the strategy of bying the Arca Swiss with

    lenses that barely cover 5 x 7 or 8 x 10, for later upgrade of you

    camera to that format, you will encounter the problem of light drop

    off with lens shi

  14. The current model is the Technikardan 45S, successor to the TK45. You

    may want to compare the T45S with the TK45--the changes are barely

    noticeable. Whether you buy the Arca or TK, you cannot go wrong--both

    are great cameras. On a calm day you likely will never experience any

    problem with lens shake with either camera fully extended. TK45's

    small lens board is advantageous when you have to store several lens

    in a camera bag or pack. Arca Swiss larger bellows opening accomodates

    lenses with larger rear elements, the type of lenses you might buy if

    you want the lens to cover both 4 x 5 and 8 x 10 formats. Most field

    photographers avoid the 8 x 10 format lenses because they cost too

    much, weigh too much, are too bulky, and the filters are

    extraordinarily expensive. With TK 45 you have only the 4x 5 format

    camera. It folds up to the size of a textbook. It is extremely easy to

    focus with whatever focsl lenght lens. With some of the 4 x 5 Arca

    Swiss models (not all), you can buy a kit to upgrade the camera to 8 x

    10. Field photographer Jack Dykinga has a website showing landscapes

    taken with the 4 x 5 Arca-Swiss F Compact. Arca Swiss offers an Orbix

    that allows geared axis tilt, but I am unsure whether the Orbix is

    available for the F Compact, or is available only with the M-series.

    The geared axis tilt is overkill for landscapes--you do not need it

    and it adds weight. People have different preferences regarding center

    lense tilt vs base lens tilt. I prefer the center axis tilt of the TK

  15. Dear Dan:

    Check Robert White in UK, Badger Graphic, and B&H Photo Video in US

    for prices on top quality new field cameras. They all have websites.

    Over the years they have maintained a good reputation. You may also

    want to consider buying a mint condition used camera. For example,

    Keeble and Schuchat in Palo Alto, CA, has about a half dozen used mint

    4 x 5 Technikas, with asking prices in the $2500-$3200 range, all

    predecessors to the current MT2000 model. View Camera magazine usually

    has numerous ads for used mint Technikas and Technikardans. Asking

    price on a mint TK45 (predecessor to TK45S) usually lies in the range

    of $1500-$2000. The TK45S has a slightly sturdier upright standards

    and weighs a few ounces more. You may also want to consider buying a

    less than mint condition camera and have it rebuilt or refinished.

    Replacement of bellows on some 4 x 5 cameras can cost you more

  16. None of these cameras have the geared movements of the Arca-Swiss or

    Sinar-P. Longer bellows of TK allows use of 210 mm lens at double

    focal length to attain 1:1 image while Technika limits user to 180 mm

    lens at double focal length for 1:1 image (absent use of Wista

    extender). You use the lightweight compact 210 mm Schneider G-Claron

    f9 process lens at both infinity focus of landscapes and for closeups

    of flowers. The longer bellows extension of TK is better adapted for

    use of 300 mm lens for closeups and portraits. Then TK has

    indents/markings that ensure precise transfer of front lens tilt to

    back plate glass more readily with indents/markings. Technika has an

    advantage in that no change of bellows is needed when choosing wide

    and long focal length lenses. Be aware that with either camera, the

    tapered bellows will limit the maximum accommodated diameter of rear

    element of the lens. However, the small lens board (96 x 99 mm) will

    ease storing lenses in ba
