  1. thanks for all the help so far... I investigated a little bit further last night<br>

    and can definitely say it's not a sharpness issue. The rangefinder is aligned<br>

    properly and the lens alignment seems to be fine from what I can see on a<br>

    groundglass with a loupe.<br>

    the negs look very sharp under the loupe, in the meantime I need to check the<br>

    digital end. thanks again, Mark

  2. hello all,

    I just picked up a used Mamiya 6 (from Adorama) in good shape, with a 75mm -<br>

    the lens is bright and clear and everything is working well. Intentionally<br>

    I planned to replace my trusted old Rolleiflex with the My6.<p>

    To my disappointment, the Mamiya doesn't hold up to the Rolleiflex (3.5E),<br>

    in image quality that is.<p>

    The Mamiya images look murky and flat and lack detail... the Mamiya lenses<br>

    are said to be stellar performers. The 'flex blows it out of the water... <br>

    Does anybody here have similar experiences? Or did I just get a bad sample?<br>

    Either way, I will return the thing tomorrow morning.

     

    thanks for your help,

    Mark

  3. it all depends on your vision - if you're not happy with the 35,<br>

    ditch it. For me, the 35 is my normal lens - it gives my pics a good <br>

    feel of room and environment (my working distance with this focal<br>

    length is usually 6-8 ft.). The 50 on the other hand feels very tight,<br>

    making it almost a portrait lens, which might be what you're looking<br>

    for. Good luck with your pick...

  4. Diafine is great with the right film at the right speed.<br>

    Compared to other developers, the results can be a tad bit <br>

    flat, since Diafine "protects" the highlights - which is a good<br>

    thing for low light photography. The results definitely don't <br>

    look like your standard developer (HC-110, D-76 etc. blahblah)<p>

    That being said, I love the results of Tri-X shot at 1600 and dev'd<br>

    in Diafine. The grain is not much more than with your standard<br>

    developer @400.<br>

    I have tried other films and the results were not as great.<p>

    Delta 3200 @2000 develops a horrid grain, tones are nice though...<br>

    Neopan 1600 @2000 works well indoors in flat light, but the <br>

    shadows are blocked - this combo doesn't work well outdoors.<p>

    Some people report great results with slow films, but I don't see<br>

    the point. <p>

    To make a long story short Tri-X & Diafine is a lovely combination,<br>

    I use it 90% of the time...<br>

    Yes, it is possible to develop different films at spec'd speed at once.<p>

    Another great thing is, the solution can be used over and over with <br>

    no loss in quality (my recent batch is 6 months old and needs to be<br>

    replaced only because solution A is running low.)<p>

    Another plus is temperature independence (within reason).<br>

    The spec development times are a bit short, 25%+ gives more <br>

    consistent results.
