Difference between Rolleisoft and Rollei Duto Filters

<p>Dear all I am new to this forum.<br>

I have searched this forum and only got some introduction about the rolleisoft and rollei duto filters.<br>

As far as I know, they are both soft filters; come in a pair of 0 and 1 version.<br>

I also noticed from people's picture of the duto filter that the glass has ecentric circles on it. Does rolleisoft filter have the same?<br>

But technically what are the differences between the two? If they function the same, which one is preferred?<br>

Thanks and regards.</p>

<p>Don't think there is a difference, duto is the type of soft focus filter it is. I've pesonally tried many types of soft filters and have yet to see anything better than the dutos for overall quality. They're best shot wide open and strength depends on the situation and your taste.</p>

<p>They are the same thing. Duto is the old designation, later the same article appears as Rolleisoft in the catalog. The difference between 0 and 1 is the amount of diffusion the lens gives. You need to shoot f 5.6 or more open aperture, the more you close the aperture the less effect the duto has.</p>

<p>I'm wondering if a Duto-type filter can be had to fit the Hasselblad 60? I don't really like the Softars.</p>

<p>Arthur, Hoya makes them, if fact I think they're the only manufacture who still does. And yes, they are better than the softars.</p>

How would you describe the difference of a Duto-Scheibe and Zeiss Softar. I have used Dutos only with Retinas and Softars with Hasselblad. Difficult to compare with two totally so different systems. Would you even have an example pair of photos.<br>

<p>Thanks for replies which really resolve my confusion.<br>

Mike, do you mean the rollei-made filters (including the duto/rolleisoft) are generally of better quality than other brands' equivalent filters? I have yet to take some shoots and compare as I am expecting to receive a duto 0 filter in a week or two.<br>

Samples of using duto/rolleisoft are difficult to be found....only a few results from fickr....</p>

<p>Karven, the quality of Rollei filters is very high, but so is Hoya. What I meant is that I prefer the "look" of the duto over the softar. Others may have different opinions.</p>

<p>Kerkko, sorry, all of my comparison shots were done some time ago on film, none of which I ever bothered to scan as they were just a comparison test--not sure I even still have them. I just prefer the duto because of its more subtle and natural "look" whereas the softars just looked more forced or artificial. Again, just my personal taste.</p>

<p>In the extreme case, the Softars give a look that reminds me of raindrops on a windowpane, with sharp and soft points of adjacent light spread across the picture. That's the result of their design. Hasselblad gives spacific suggestions on how best to use them, which may give better results.</p>

<p>Arthur,</p>

<p>Raindrop efect exists when using wide angle lens focused close and spopped down. I have had it with CFi 50 mm focused to less than 1 m and stopped to f:16. Although I suppose that in these conditions Duto would have given it's typical landscape figure to the photo.</p>

<br>

I have a Rolleisoft 1, and it appears to have <i>concentric</i> circles. I use mine on a Yashica Mat 124G, which has a bay 1 filter mount. Here's an example of the effect, shot at f/3.5, which is wide open, with Kodak Portra 400:<br>
