SIGMA DP1s, overcoming the long close focus distance

The only annoying thing on the DP1s is the long close focus distance, that avoids the use of the cam for product-like shots.

To overcome this, a friend of mine thought on using a closeup filter lens.

I followed his recommendation and tried with a 4 diopter lens, On top of the HA-11 adapter:



Magnification is really improved. (Don't pay attention to the following two pictures, are shot handheld @ 1sec, so they are awfully blurred, but are good to show the magnification).

Without the closeup lens:



Same distance, with the closeup lens on:



Quick samples: 1/10s, F4, ISO200



100% crop of the last one:



Another sample:



This may solve the problem.
Although the results are not bad, maybe I should try with a better lens. This one is a cheap chinese one...

Hi,

You should try an achromatic close-up lens, with two elements. Those lenses are color corrected and have less fringing.

Thanks, Afshalders.
Do you know a brand, or where can I find one?
Thanks in advance.

If I remember well the Sigma's close up lens dedicated to the DP series is a two element achromatic. The model is the AML-1 and it's rather expensive.
