  1. There has yet to be a good comparison between MF and digital

    published on line (a 4x5 was compared here

    http://www.outbackphoto.com/reviews/equipment/Canon_1DS/4

    5_film_1ds.html but talk about apples to oranges! ) A problem

    with the Eos 1Ds may be wide angle color fringing

    (http://www.fredmiranda.com/1Ds_review/index_noise2.html). If

    you are doing wideangle work perhaps you would pause before

    going to the digital cameras- already their problem with those

    available having lens multiplication factors of 1.3 to 1.6. This

    problem may not be noticable to you or will likely be solved soon.

    Then again, one would think digital backs will eventually be

    affordable, full frame and therefore make MF probably again

    superior in image quality. If you are just starting, I'd probably go

    with the 14n or D1s. Remember that "obsolete" is Exactly what

    these companies want you to say, so you'll be in that never

    ending hamster wheel of feeling behind so as to cough up more

    dough. I'll bet a 1ds will last quite some time, and WILL NOT be

    obsolete in a year or two. This is a more difficult decision for

    those who already own MF gear and don't have a high volumn of

    work: Do we get out now or wait for a cheaper back?

  2. A used Pentax 6x7 w/ a135mm macro. I'll bet you don't do so

    many as to have a digital back pay for itself. Put the money into a

    high quality scanner instead or pay for each scan. Cheapo

    scanners- rated at 1200 or 2400 dpi- will give cheapo results.

    Your original negs will be top notch with either the Pentax or the

    more expensive RB-RZ.

  3. Extremely unlikely. Simple slave flashes are enough trouble UW,

    let alone an infrared signal. Its cool to pursue different methods

    UW but you'll probably have to house the 550 and hardwire it to

    the camera unless the distance to the flash is really close. Try it

    in a pool.

  4. The Nikon is slightly-maybe ever so slightly- sharper than the

    Minolta in my tests BUT the banding issue makes scanning in

    "super fine mode" necessary and therefore completely

    impractical (one hour scans). I feel for the money the Polaroid

    120 is the best value (having tested all of them), though its main

    weakness is the lack of Digital Ice.

  5. I'm not sure as to the experience of the previous poster but "any

    lens that changes focal length...is a bad choice" is simply

    incorrect. AF in macro can be limited by low light levels but in a

    practical sense the lenses function much as they do above

    water. Quite a few UW photogs do not use AF in macro due to

    precise depth of field issues, not because of theorectical

    concerns. The Nikon 105 non AF and its newer sister have been

    workhorses of housed UW macro systems for years: check out

    any "how to" book on UW photography. Also, macro is in fact

    EASIER than any other type of UW photography (and of course

    requires flash). It is true that minimum focus distances don't

    mean much- what matters more is the size of the subject matter

    you want to shoot and if a particular macro lens will handle that

    magnification. Working distance to the subject w/ the 105 is a

    good compromise between room for flashes and water column

    that might obscure your subject. Longer macros help with shy

    subjects just as they do above water but cloudy water will give

    you flatter results. The 60 is loved by many but can crowd small

    subjects and at high magnification it can be difficult to get a flash

    lined up between port and subject. I suggest finding the classic

    "Under a Rainbowed Sea" by Chris Newbert wherein each shot

    is referenced to the lens used (Canon 50mm vs 100mm

    macros).

  6. Can anyone check their flash to see if you can set the HSS mode

    "manually" w/o attaching it to the camera? The Nikon SB 28

    requires you to attach it to a dedicated camera to set it to FP

    mode(same as Metz's HSS) I of course understand that only

    certain cameras can be used with HSS.

    THANK YOU

  7. I personally prefer the 5 pt system seen on the F100 as it is

    much less cluttered than the higher end Canons. The points are

    very useful outside the center though not always used. I have

    always tried to do anything with my MF cameras that can be done

    w/ 35mm including action now that AF is available. But come on-

    do we have to lag behind 35mm again?! At these prices?

  8. I've had roller pins on my inserts loosen and fall off but that leads

    only to "late" final wind. Sounds like you have a short: maybe you

    need to send it to Colorado. Make sure you put NEW batteries in

    it, put a lens on wide open and try a shot with and w/o the insert

    out in the sunlight.

  9. If used as an exposure meter I'd set it at 100 iso w/o

    compensation. Overexposure is always better than

    underexposure w/ print films. Some would argue that these 160

    films are really more like 125 or 100 speed anyway. In other

    words, error towards over-exposure: if the coolpix looks good (@

    100), the NPS will too.

  10. If you have large black areas do @ least a 4x multiscan. As you

    said, you can see for yourself. Don't waste time w/ 16 bit color.

    I'd scan @ 3200in/300out for a master file. Finally, I found that

    slides were too dirty w/o ICE. Same slides scanned much

    cleaner in the Polaroid 120 & the Nikon 8000 so I don't know if

    the Minolta somehow picked up its own dust. No obvious winner

    in this contest: Minolta best color, Nikon sharpest by a hair,

    Polaroid "cleanest." Difficult to time, but banding w/o "superfine"

    mode ruled out the Nikon for me d/t LONNGG scan times.

  11. This reminds me of the mid-late 80's when people discussed

    whether anything (Vevia) could ever overtake Kodachrome...

    clearly a matter of timing. MF exists because it generally gives

    superior results compared to 35mm. If smaller cameras deliver

    better results than heavier MF gear and deliver me from the ball

    and chain of two round trips for processing and another one or

    two for scanning (or a $3000 scanner) and the cost of $20 a roll:

    SIGN ME UP. For now though I have just invested in another MF

    body and lens. It won't be till late 2003 when our beloved rollfilm

    is surpassed and then I may resent the built in obsolesence of

    the Dcamera and the fact that I no longer have any format

    advantage so I will just have to make good pictures.

  12. That's really the jist of it- coudn't we just combine the strong

    points. The Minolta scans were so dirty it must of been the

    scanner and not the slide. ICE was NEEDED on every scan.

    Maybe that's why it wasn't as sharp as the Nikon. But if you had

    to scan everything in "Superfine" mode to get rid of the banding

    on the Nikon:forget it! ~1 hour per MF scan! I'll be testing a new

    UMAX flatbed ($4000) next...
