  1. I've owned almost every MF there is from a Lubitel to a Yashica D, MAT, and 124, Bronica S2, Mamiya C330-220, RB, RZ, 645 .... even a Seagull!

     

    There are some pitfalls to buying a Kiev MF camera, for one thing stay away from KievUSA! Mike Fourman of Kiev Camera is a gem as is Jenna Kaplan. The K60 is more reliable than the K88, it's simpler. I have used both 88s and a K60 for over a year with great results. The lenses resoulution numbers you find published on the web are accurate, and they are not bad (I have run a number of Rez tests myself, most of the Kiev lenses are better than the film), but if you have a K60 or an 88CM you can buy German Pentacon lenses if you want.

     

    I have found the Kiev bodies to be surprisingly good if you stay away from the period 1990 -1993 (the first two digits of the serial number is the year of mfr.) If you are worried about reliability, buy 2 or 3, they cost about $100 a throw. A lot of the bad experiences new users have are because they have not owned a 120 camera before and don't load them correctly. You have to follow the instructions with 120 cameras or else you get bad spacing and/or light leaks.

     

    I have a 30mm Fisheye that I bought out of a dealer in Moscow for $175 and it is a fantastic lens, the fit, finish and performance are all first rate. The Hassleblad 30mm fisheye is $5979, I'd be afraid to take that lens out in public!

     

    The TTL lightmeters are very accurate and are voltage regulated. They are owner adjustable and sometimes adjustment is required. The shutters I have tested are within 1/6 f/stop except for the two highest speeds (just like most focal plane shutters). The ground glass viewfinders are the brightest I have used and the waist level finder on the K60 is an engineering marvel, having about 4 different operating modes!

     

    Stick with the factory shutters, some dealers have tried to put cloth shutters in K88s, they don't fit. Aftermarket flocking is OK as in MLU, MLU is recommended. The shutters flash sync at 1/30 and slower, but unlike numerous other cameras, they will *not* fire the flash if the shutter speed is too high... another source of poor construction rumor.. but I call it good design.

     

    Today I have a Kiev 60, a Mockba 5, and a Yashica MAT and will soon have an 88CM. I am more into LF and use the Kiev mostly for astrophotography. I have no reservations recommending Kiev cameras to anyone who wants to get into MF, especially if they buy from Kiev Camera in Altlanta.

  2. >Bill - What's the deal on testing the lenses?<<

     

    <p>

     

    1. By using a standard target, I can compare lenses I do have with the

    published numbers for lenses that I don't have. Why? because I may want

    to sell one and replace it. I would even like to know how the

    individual lenses compare with others of the same type.

     

    <p>

     

    2. I can test my lenses at various distances, allowing me to choose the

    proper lens for, say, close-ups.

     

    <p>

     

    3. I can compare my lenses with each other. Knowing the relative

    sharpness of each lens helps me decide which lens to use to obtain the

    desired results.

     

    <p>

     

    4. By testing now, and in the future, I may be able to detect any

    change in a lens' performance.

     

    <p>

     

    5. It helps me to judge a film/developer performance and to find any

    weak spots in my technique.

     

    <p>

     

    6. I have aquired a taste for lenses made in the former Soviet Union.

    These lenses are often a mystery performance wise, and there is an

    awful lot of misinformation circulating about them.

     

    <p>

     

    The Edmunds target also allows me to judge the color performance of my

    respective lenses. Important for astrophotography and very hard to

    judge by "eye".

     

    <p>

     

    I shoot enough variety that I find that every lens gets used, sharp or

    not. In fact, I have often used a lens that was *not* sharp for

    portraits. I also understand that "sharpness" is more often a product

    of local contrast and edge effects than lens resolution.

     

    <p>

     

    Thanks for your interest!

  3. I use RO (pure) water and fill and dump the tank 3 times in 10 minutes.

    Pure water has a great affinity for hypo, much more than tap water. I

    learned this trick from an old timer at Kodak many years ago, the same

    one that told me about developing slide film in C41 soup.

  4. In the old days we shot Panatomic -x and developed in Accufine. Both seem defunct now. I want to test some MF and LF lenses using the big Edmunds wall chart.

     

    <p>

     

    I have some TMax 100, 400 in 120 APX100 & Arista 100 in 4x5, and Tri-X in both. I tried TMax100 in TMax developer but ran into grain problems before I lost the patterns.

     

    <p>

     

    I have Rodinal, D76, Dektol and Microphen available.

     

    <p>

     

    What would be the best combo for lens testing? Should I shoot at a high ISO? (ie: 100 at 400).

     

    <p>

     

    Thanks!

  5. I have been making lensboards for my Tachihara. I use the "bendable"

    3mm plywood for light traps and thin basswood or cherry for the board.

    They work well.

     

    <p>

     

    You need access to a scrollsaw, or you could do it by hand with a

    coping saw. (I have a scrollsaw).

  6. Andy, I'm not sure of what your problem is. Exposures too short?

     

    <p>

     

    I am using a similar setup. I use a old Kodak safelight with a 15 watt

    bulb 4 feet from the neg. My starting time with Polycontrast RC is 2

    seconds as recommended by Kodak for that arrangement. I use Dektol 1:2.

  7. Can anyone point me to a good source for "how to" closeup lighting? I'm always dissapointed in my close up lighting whether natural, flash, or photoflood. My lighting experience has been in portraiture and perhaps thats a liability eh?

     

    <p>

     

    By source I mean books, web sites, etc.

  8. I don't remember the details except that I spent hours cutting with a

    dremel mototool, but I modified one myself back in the early '80s. The

    only thing I bought was a 4x5 neg carrier and a lens.

     

    <p>

     

    The biggest problem I ran into was light falloff at the edges. Most of

    the time, however, it rather nicely matched the light falloff in the

    camera lens so it all sorta came out in the wash. I did many 16x20's.

  9. You guys have talked me into going for the 203 7.7 Ektar. They also

    have a couple of shorter Ektars in Supermatic shutters, a 127mm f4.7

    Graphic and another without the X sync. A 127 *plus* the 203 f7.7 would

    fill out my kit, but I am not sure if the 127s are Wide Field Ektars.

    They list both as covering 4x5, but the refernces I see in the FAQs

    here are to the WFs.

     

    <p>

     

    So, should I also get the 127 4.7? Do I want to go for the one with X

    sync because it's likely newer? The exchange credit I have will cover

    both lenses almost. Or should I forget the 127 unless it's a WF?

  10. Howdy guys,

    Thanks for your help in the past.

    I am looking for smaller lightweight lenses for my Tachihara. I am returning a Rotelar 270mm because it was too big, too heavy.

     

    <p>

     

    I am thinking of a Geronar 210mm f/6.8. It appears to be light weight and compact. I'd rather have a Xenar I think, but none are available.

     

    <p>

     

    I also need a close up lens in the 135 or 210 mm range. I have a 90mm Angulon and a 150mm Caltar S II. I am wondering how a slightly longer Angulon would work at 1:1. I think they made a 105 or 120? I doubt the Geronar would be very good at 1:1 and I don't know if the Caltar is good. My goal is to have a lens that I can carry in the field for landscapes but also use for a flower sized close-up. My 6CM SLR is just too heavy!

     

    <p>

     

    It amazes me that these used LF lenses sell for much more now than new in my 70s and 80s catalogs!

     

    <p>

     

    Any recommendations will be greatly appreciated.

  11. The Epson TWAIN driver does unsharp masking at scan time. This *is* the

    best spot in the chain to do it. Because the scanner driver has all of

    the physical pixels available to it, it is possible to actually

    increase sharpness as long as you aren't scanning at max optical

    resolution. (like increasing DMax with a higher bit count ADC) The

    problem is finding out whether any particular driver actually does

    this. I'm still not sure about the Epson driver.

  12. Exposing at ISO 80 and decreasing the development time by 20% made a

    huge difference. Perhaps allowing the D-76 a day or two to "season"

    helped. (I wonder if my using RO (pure) water has anything to do with

    it?)

     

    <p>

     

    Now I can see every step on the Kodak scale and the shadows are smooth

    while the overall density is up. The sharpness is better as well. I can

    see all this with a loupe.

     

    <p>

     

    Anyway, this is a much better starting point. Thanks!

  13. Yes, I mixed it about 2 hours before I used it. I used RO (pure) water.

    I don't see how it could have oxidized but I suppose anything is

    possible.

     

    <p>

     

    I have some Microphen I could try, but that's primarily for pushing I

    think. I also have some Rodinal on the way.

  14. I received the Arista film. First, it's the same thickness as the Kodak

    and Agfa film, perhaps a tad smaller, .0078 vs .0082.

     

    <p>

     

    I shot some test sheets using the scale in the Kodak Prof. Photoguide

    and other stuff, developed in D-76 1:1 according to the instructions on

    the box and scanned. I used 2 #2 reflector photofloods and calculated

    the exposure using the Kodak Master Photoguide for photoflood lighting

    at ISO 125, 5:1 lighting ratio so I got some light shadows in the pic.

    I used a quick disk to get a bellows compensation of 1.1. I bracketed +

    - 1 stop using both shutter speed and f-stop. Negs that should have

    matched did.

     

    <p>

     

    The highlights somehow have too much contrast. From Zone V up, the

    scale is stretched giving the soft shadows a harsh appearance. Zone 3

    density is OK. There is quite a bit of grain and local contrast is only

    fair, no real "edge effect".

     

    <p>

     

    So far, I don't like the results. Perhaps D-76 at 1:1 is the culprit.

     

    <p>

     

    What am I doing wrong? - Thanks in advance.

  15. I have collected a number of film holders here and discovered that older wooden holders are generally about .005" "deeper". I have one that came loaded with old Ansco film and had a paper sheet underneath.

     

    <p>

     

    Using a micrometer on my Tachihara back, the ground glass position is nearly identical to the older wooden holders. When I calibrate the depth of the glass, put in a wooden holder, the depth is within a few thou. The plastic holders are about .005" too close.

     

    <p>

     

    What gives? are the newer holders made for thinner films?

  16. I changed the eGroup settings, you don't have to become a member to

    access the files section. Anyone can download the file(s).

     

    <p>

     

    Any questions, just ask. The technique that this scale implements is

    found here on the LF site (Paul K Hansmas 4 page article). The scale

    saves you having to measure the near and far focus points on your

    camera rail then calculating the difference and looking up the f/stop

    in TABLE I of Hansmas article. The scale provides that reading direct.

    You just note the position (mark the rail) at either near or far, focus

    on the second point (far or near) then read the best f/stop directly

    from the scale.

     

    <p>

     

    If anyone would like me to print out a copy for them, send me a SASE

    (email for address) and I will send you a printout. You do need a

    decent printer (600dpi+ is best) and a accurate graphics program to

    make your own printout.
