GUARANTEED THE BEST INVESTMENT YOU'VE EVER MADE IN QUALITY.
Did you know that most modern enlarging lenses produce sharper prints at f8 than they do at f16? They do, try it. Stopping down your enlarging lens to f22 or f32 is devastating for print sharpness.
The reason for using small apertures - f16, f22 or even f32 - has been to compensate for mechanical errors in the enlarging process. It has been necessary to compensate for poor alignment between the stages on the enlarger, and to compensate for the natural light fall off produced by the taking lens and the enlarger light source.
New modern "long focal length" camera lenses have little or no light fall off.
Durst enlargers are the best built enlargers in the world. They are all adjusted to very tight alignment tolerances. Durst CLS1000, CLS1840, CLS2000 and DL2000 Dichro heads are the most even light sources on the market. With the NEW Durst PROLA lens adapter it is now possible to squeeze the last few drops of mechanical quality from a Durst enlarger. The NEW PROLA allows adjustment of alignment between the negative stage and the lens stage to an accuracy of 1/2000 Inch. (1/100 of 1mm).
With the NEW Durst PROLA lens board you can print top quality - tack sharp to the corners - fast and efficiently at f8 or even 5.6.
