DP2 Quattro, Marumi DHG200 and Raynox DCR-250


While taking photos of the Christmas tree ornaments it struck me that my two achromatic lenses, Marumi DHG200 and Raynox DCR-250, have increased Sigma DP2 Quattro’s magnification factor quite considerably, despite DP2Q’s short focal length. I found that quite interesting, given that achromatic lenses are supposed to increase the magnification factor more, the longer the focal length of the lens is. Short focal lengths, like the 30mm lens of the DP2Q, are not suited for such gimmickry anyway, and even less so, if they are optimized for long range instead of close range. And this is certainly the case with the DP2Q. However, I’m going to go into more detail on that in a later blog post. Still, it is interesting to know what kind of macro subjects, and most importantly how big, one can capture with such a combo.

Since the weather was not exactly suited for taking photos outside, I took some photos in the house instead. A one euro coin was my subject of choice. As you can see down below, both Marumi and Raynox increase the magnification factor considerably. The difference between the former (5 dpt) and the latter (8 dpt) is noticeable, but in no way huge. If you crew both onto the lens the magnification factor increases to above 1:2.

Since I have a Marumi with a 52mm filter thread, I use two step down rings (58mm to 55mm and 55mm to 52mm), in order to attach the achromatic lens onto the DP2Q. The Raynox is far more flexible in this regard – but also much larger – since a special adapter with a clip-on mechanism, which makes it possible to attach it to lenses with filer thread diameters ranging from 52mm to 67mm, is included in the box. Without this adapter it can only be screwed onto tinny lenses with a 43mm filter thread diameter.
