  1. Wonderful shot Douglas, and thank you for not detracting us

    from the shot by giving us any boring technical details. I shall

    now down load it so that I can show it to my wife as well. All and

    all quite an enjoyable thread really, without any references to

    "domke bags" or the "bokeh of Noctilus" or " I have this very

    expensive outfit, what is the most expensive other gadgets I add

    to it" stuff.

  2. Dear Mitch, I am just being practical. For the price and weight of

    50/1, I personally would buy & carry (and I have) a 50/2 and a

    90/2.8. The 90/2.8 shot at f4 would probably produce at least

    some of the flower in focus and give a very nice out of focus

    background. Just a personal observation, I don't think we have

    to agree.

  3. Dear Andrew & John,

    To test this lens hood, I shot an evenly lit white wall (measured

    all 4 corners and centre with spotmeter) at f2, and at 1.2m (3.6')

    and got serious vignetting. I also a did the visual test (similar to

    checking 4x5 camera lens coverage with case of excessive

    movements), and this also indicated a vignetting problem. It is

    interesting that you guys don't seem to have any problems. Did

    you try the lens at close quarters ( where the light fall of would be

    more pronounced).

    Regards Sait

  4. From an earlier thread:

    "hi all, hcb used a 50/1.5 zeiss sonnar in ltm for most of the 40s,

    50s and 60s.

    I thought this was a Leica forum.

  5. Another reason lens manufacturers are re-designing their

    lenses for digital use is to reduce colour fringing. Because the

    larger digital "grain" (in relation to film grain) exaggerates this

    effect. I understand that's one of the reasons why the latest

    Nikon wideangles contain ED glass as well as aspherics.

     

    <p>

     

    For the record comparable 120 lenses have inferior MTFs to

    35mm lenses, and 4x5 lenses have inferior MTFs to 120 lenses.

    However, to get a 240mm wide output 4x5 needs to be enlarged

    about x2, 120 about x4, and 35mm about 6.6 times. This fact of

    course hides fact that 35mm film is actually sharper that 4x5 film

    and 35mm lenses have the best MTFs

  6. I will reply first to Richard. I have test scanned Velvia v Reale

    and liked what I got from the neg film (both sharpness and

    colours). I now shoot all my personal work on 35mm neg film,

    mostly Reale or NPH, depending on the project. ( I have tried

    other Kodak and Fuji neg and tranny films). I think there has

    been a great improvement on neg films with scanability, colour

    palet, grain, sharpness, tonal range, etc. But these are all very

    subjective things, and you should do your on tests to see what

    you like. It is of course very important to get your film processed

    at a professional lab, this will all but guarantee that your film will

    be correctly processed and will be free of scartches and dust.

     

    <p>

     

    Now, if we look at Jays experience with Canon D30 v. Canoscan.

    First I will give you the technical data on these equipment:

    Canon D30 - chip size 15.1x22.7mm / pixels 2160x1440 = 3.1

    megapixels x3 (RGB) total 9.3megapixels

    Canosan FS4000 - scanned area 24x36mm / pixels 3780x5669

    = 21.4 megapixels x3 (RGB) total 63 megapixels

     

    <p>

     

    The chip size on the D30 is about 60% of FS4000 which makes

    the 9.3 megapixels of D30 equivalent to approx 6mega pixels in

    relation to FS4000 for a given reproduction size. Now if

    someone can explain to me how 6 megapixels produces a

    result sharper than 63 megapixels does I shall be delighted.

     

    <p>

     

    One possibility is that in-camera sharpening on D30 was turned

    on, but that the FS4000 scans were viewed without use of the

    unsharp mask.

     

    <p>

     

    Rob, regarding direct digital capture, with 35mm high end digital

    SLR cameras, the problems are dust particles on ccd chip (or

    whatever is protecting it), lack of shadow detail, lack of high light

    detail, narrow dynamic range, high price of cameras, list goes

    on. It all depends on ones needs. If I was a press pro I would

    only use.digital cameras, but if I need top quality 35mm digital

    results, I will shoot neg film and scan it, until someone can show

    me a better way of doing it.

  7. Jay, your information is not correct. For quality digital work, the

    recommendation is to shoot neg film (not tranny) and then use a

    scanner to digitize the image. You haven't given us resolution

    figures, degree of enlargement and other factors, but I cannot

    see how a 6mb from an SLR file produces a sharper, better

    image then an over 20MB file (from a 2700dpi scanner). Things

    just don't add up. May be you can enlighten us.

  8. Here is my 5 buck's worth:

    a. If you are using Leica lenses only, it is possible to adjust the

    Hexar RF to focus OK with these, both at infinity and close up,

    from wide angle to 90mm f2.8 inclusive. I don't think it is

    possible to use Leica and Konica lenses on the same camera

    for critical results.

    b. I don't think the exposure meter is centre-weighted as

    claimed, not in a Nikon sense anyway. It is more of a selective

    wide-spot meter (bit like M6), and the sensitivity is elipse shaped

    instead of being round as in the M6. I am not sure that a

    wide-spot meter is a good basis for AE operations. I imagine

    this will be the problem with M7 AE too. I am also not sure

    whether I like the elipse shaped (as opposed to round)

    sensitivity of the meter.

    c. There is a shutter lag, and I feel that I can take three shots in

    quick succession faster with manual wind Leica Ms or Nikon

    F2/3, than with the RF on S or C setting. Shutter lag can be

    minimized by using the C setting in manual exposure control,

    and for the first shot by pressing the shutter button halfway, ready

    to go, but this does not help with the following shots.

    d. If you are shooting in the street or a public place then the RF

    feels just as quiet if not quiter than the Ms. If you are at home

    "playing with cameras" than Leica sounds better. With the RF

    even when people know I am taking photographs, it is difficult for

    them to know how many, if any shots I have taken, because there

    is no hand/arm movement advancing the film.

    e. I am not sure about film loading. I never had any problems

    loading screw or M Leicas, or Nikon 90s or F100s but have had

    the occasional "non-load" with Nikon F4s and the Hexar RF.

    f. Although RF is similar in weight to the Leica Ms, it has a more

    fragile feel. Specially some of the dials and rf mechanisms feel

    and look light-weight. The paint finish scratches easily.

     

    <p>

     

    At the moment I trust the RF more than my M4-P. If Leica's

    "legendary build quality" was real than we would not be forced to

    consider all these alternatives, for I don't think anything matches

    the tactile pleasures one experiences with a Leica.

  9. Ray has the right answer! As additional info, if you leave a wine

    bottle in a freezer for an hour, it almost freezes despite all the

    alchohol, so I don't think it would be a good idea to leave your

    camera and film in freezer for whatever reason. The film will take

    about 2 hours to come to shooting temp.

  10. Advice from ex-Turk now living in New Zealand. I go back to

    Istanbul once every 2 years to visit my parents. Best time to visit

    is late September and early October. The weather is not very hot,

    but nicely settled around 24C (Can go upto mid 30's in summer).

    Plenty of fresh fruit and vegetables. From 01 October airfares

    are cheaper (at least from New Zealand). March can be bitterly

    cold and miserable They will hand check film at the airport

    without any problems - just ask. ( I was there last October). You

    can contact me direct by e-mail if you wish, for any specific

    questions you might want to ask.

  11. I agree, it is a very 80's corporate brochure look. The difference

    is photographers tried to make models look like real people,

    where as you have succeeded in making real people look like

    models. Photogaphic source books (e.g THE BLACK BOOK)

    have been full of this type of work for a long time.
