  1. We should stop criticizing the contents of the shots and thank Al

    Smith for debunking another Leica myth. What beats me is why

    would anyone want to spend thousands of dollars, carry around

    all that unbalanced weight, and put up with all the abberations

    and light fall-off at the edges, for the sake of 1 stop? Thanks very

    much Al Smith

  2. When slides/transparencies are scanned for mechanical print

    work, contrast is reduced or stays the same. When you get

    photographic prints from slides, there is no effective contrast

    control, therefore results are usually dissapointing. Professional

    labs can make contrast reducing lith-film masks, but this is very

    time consuming and thus expensive, and results are a bit more

    satisfying though not perfect.

  3. Years ago, I had a brand new M6 classic straight out of the box

    that had 1/1000 deliver 1/500; 1/500 deliver 1/350; 1/250 deliver

    1/ 150, etc. Sent back to LeicaGermany for repair under

    warranty. Camera came back with 1/1000 delivering 1/650, with

    the slower speeds also slightly out. I have sold it immeadiatly

    and bought a second hand M4-P. 1/1000 was slightly slow which

    has been locally adjusted and delivers all the shutter speeds as

    marked. By conrast I still own 2 Nikon F2's and 1 Nikon F they

    have never needed any CLA and deliver correct shutter speeds.

  4. Further to my earlier posting I also have 2x Nikon F2, an FE2, an

    FA, F3, and 20, 24, 28, 35, various 50's,55, 85, 105, 200, 300

    lenses, I use them all professionally. Also had 2x F4's but sold

    them - too heavy. Never had a shutter problem. Only service

    neeeded was re collimation on 2x F3's and 1x F4.

  5. Brand new Leica M6 "classic" purchased Dec94, from local

    distributor. Faults straight out of the box: a) Shutter slow by 1

    stop @ 1/1000, 1/2 stop @ 1/500, 1/2 stop @ 1/60 b) Two shots

    in rapid succession (at the same setting) results in second shot

    being 1/2 to 2/3 stop lighter; c) Parallax not working with 35 &

    135mm lenses. d) Uneven exposure across frame. Camera

    sent twice to Australia by local distributor for repair. Parallax

    problem remedied, shutter problems not. Camera sent back to

    Germany with a note from the supplier, recommending

    replacement. Camera returned from Germany re-built and with

    a note saying that it should never have left the factory in its

    original condition. Whole process took 6 months. All work done

    free of charge under the warranty and during this time the local

    agent kindly lent me a "demo" camera. This camera was fine

    apart from 1/1000 sec being 1/2 stop slow, which is the norm.

     

    <p>

     

    Brand new 50/2 purchased with the camera. Found to be slightly

    short focusing compared to 21, 28, 35, 90 and 135/4. Adjusted

    in local repair shop.

     

    <p>

     

    Brand new Elmarit-M 28/2.8 purchased from local distributor.

    Micro streamer like bubbles in lens. Sent to Germany, returned,

    having been repaired under warranty, after 3 months.

     

    <p>

     

    Brand new Elmarit-M 90/2.8, the red dot fell off as I took it out of

    its box for the first time.

     

    <p>

     

    Brand new 35/2(last non-aspheric) 1/2 stop under exposure at

    all f-stops. Returned. Since bought a second hand mint one, no

    problems.

     

    <p>

     

    Sold the original M6, and bought 2x mint- M2's (1 button, 1

    lever rewind) shutter accuracy & travel problems even after CLA.

    Sold both at profit.

     

    <p>

     

    M4-P (current camera) purchased in mint- condition.

    Rangefinder fine tuned, 1/1000 speed adjusted. Have to be

    careful when changing lenses in bright sun outdoors, light leak

    problems (twice) through the bottom of the shutter curtains.

    Otherwise happy.

     

    <p>

     

    Since my problem with the original M6, I know test even brand

    new equipment before I buy.

     

    <p>

     

    I think, when they work properly, Leica equipment are the most

    tectile of all photographic equipment, that is why I still use them.

  6. I use the same 28mm lenses (latest Elmarit 2.8 and Nikkor 2.8

    Ais that focuses to 20cm). Both are very nice lenses. I get the

    same feel as you do that when I shoot off centre HEADS ( or 3

    dimentional round objects), at near distances, off centre, Nikkor

    produces slightly more distortion (stretch) than the Elmarit. This

    is just a feeling, I haven't actually done any tests.

  7. Paul I have been doing very similar tests for the last five years

    (everytime I buy a new body and/or lens). My tests are done at

    1.8m (each time the same row of antique cans in my kitchen -

    these are covered in all sort and size of intricate typography and

    lines), and exactly at 50m (always the same building with signs

    on it and in open shadow). I scan a 5mm square portion of the

    film (at centre and at edge) at 2700dpi (Nikon LS-1000). At pixel

    size, as you have pointed out it indeed corresponds to about x40

    magnification producing 950000K to 1mb files - saved

    uncompressed.

     

    <p>

     

    Having analysed your test results thoroughly and compared

    them with my results, may I suggest the following:

     

    <p>

     

    1)If you haven't already done so please check both your Leica

    and Nikon F3 to see whether they focus correctly or not. I find the

    best method for this is to first shoot a frame at the best focus

    point as indicated by the camera rangefinder, then take further

    2-3 shots at TINY increments turning the focusing ring first

    clockwise, then anti-clockwise from the camera indicated point.

    With Leica you will have to do this test with every lens at 1.5m

    and 50m. Don't be shocked with the results. With an SLR I

    would recommend a wide and a tele lens again at 1.5m and

    50m. ( I have owned 2 F3 bodies - both bought brand new, and

    although technically within factory tolerances, both needed

    personal tweeking to focus spot on). Then scan and analyse the

    film as below.

     

    <p>

     

    2)I would recommend using Fuji Reale 100 Neg film for this type

    of testing. I have used Velvia, Ektachrome E100VS, Kodak neg

    films and find that neg films scan better and Reale scans best.

     

    <p>

     

    3)For scanning test negs set the scanner gamma to 1.5. Do all

    colour and density corrections on the scanner and then - MOST

    IMPORTANT - focus the scanner manually at the exact spot you

    are going to scan for EACH SCAN.

     

    <p>

     

    4)Once the scan is in Photoshop, I would recommend 2x 100

    (not 1x 200) unsharp mask. I apply 3x100 but you might find the

    result too gritty. The result will be similar to what one would get if

    one was using a good enlarger/lens combination with a

    CONDENSER, for the tests. I save the file uncompressed.

    Compression makes a bit of difference but only if you look at the

    compressed and uncompressed files side by side. To evaluate

    the scans when comparing, look at them at both at 100% and

    50%.

     

    <p>

     

    I am hoping that you will find the above suggestions, made with

    the best intentions, constructive and try them. Please do not

    hesitate to contact me directly if you wish.

     

    <p>

     

    All the best

  8. sorry for the spelling and other mistakes in my previous posting,

    it should read: "I am 95% certain that Nikon manual cameras

    (F, F2, F3, FM2, etc), Leica M's, and Hexar RF viewfinders have

    values of -1 diopter. For example if you need a +1 diopter

    correction for these cameras and want to purchase the makers

    correction lenses, you order a "0" diopter viewfinder correction

    eyepiece. If on the other hand, you want to get your optician to cut

    you a diopter correction lens to add to the viewfinder assembly

    then you ask your optician for +1 diopter lens. "

     

    <p>

     

    Best method is to take the camera with you to the optician and

    find what sort of diopter adjustment makes you happy. If you

    want the camera manufaturer's viewfinder correction than you

    have to take the viewfinder's original diopter measurement into

    account as I have explained above. On another note, If your

    perscription glasses are "progressive" that is no correction on

    the top and getting more correction towards the bottom of the

    glass frame then it is easy to use the camera + new diopter

    combination without having to take your glasses off. However , if

    you getting standard glasses then you might have to take them

    off to look through your camera + new diopter combo. I hope this

    all makes sense.

  9. I am 95% certain that Nikon manual cameras (F, F2, F3, FM2,

    etc), Leica M's, and Hexar RF viewfinders have values of -1

    diopter. For example if you need a +1 diopter correction for these

    cameras and want purchase the makers correction lenses, you

    order a "0" diopter viewfinder correction eyepiece. If on the other

    hand, you want to get your option to cut you a diopter correction

    lens to add to the viewfinder assembly then you ask your optician

    for +1 diopter lens.

  10. Seperate rangefinder made by Leitz of the same kind as used by

    Leica 1, but has no mounting bracket to attach it to camera.

    Serial no: 24236. Brassing on the edges but accurate. Black

    body with chrome dial. Any info including value would be greatly

    received. (The Leica Collectors Guide at the local library is out

    for 3 weeks !!)

  11. As far as I know, the camera and a Leica enlarger was specially

    imported for my grandad, new, into Turkey. He was a doctor and

    very interested in gadgets. He apparently also had the first

    "wireless" radio in his town. He would not have been in a

    position to first purchase a Type 1 and then had it converted to

    type II (D). Unfortunately this is all my dad can tell me ( I am 54

    and he is 88, my grandad died when I was 4!). I have been

    using the camera and the enlarger until recently. The shutter

    curtains have finally perished. I am hoping to get them rebuilt

    soon. Thanks for all the trying.

  12. I had both 135/2.8 and 135/4 at the same time. Comparing them

    side by side I decided that 135/2.8 was too heavy & awkward to

    use, specially if you are working from a bag. The goggles snag

    on everything and anything. I have since sold it . The 135/4 by

    contrast is a very usable lens and produces fab results specially

    if your range finder is spot on and worth the one stop loss.

  13. Having done side by side tests of all major colour transparency

    films for my prolab & Kodak NZ (except the Kodachromes -

    neither clients nor I like to wait for a week while they processed

    in Australia), E100VS would be the next best film, specially if

    greens are important. However, if you shoot the same scene on

    both RVP & E100VS, you will see that nothing matches the depth

    of Velvia in highlights, midtones or shadows. Beware of pink

    asphalt though, specially if you shoot through Nikon glass.

  14. jay, the brochure mentioned was from late 80's or early 90's, if

    and when I find it I will let you know, 1997 leica fotografie special

    issue leica M6 quotes 100,000 cycles, and goes on to say that it

    is not uncommon for a camera to come back for "inspection"

    after 200,000 or more exposures.
