Small Is Beautiful:
Getting Close With the Raynox DCR-150 Macro Conversion Lens
I’ve added a lens to my camera bag, and I’m looking forward to resuming my long dormant love affair with macrophotography. The new lens is lightweight, it slips easily into a pocket, and it cost less than USD90—even when I added a protective UV filter. Best of all, I can use it with three of my four existing lenses. Care to guess what I’m talking about? Well, I’ve already given the game away in the title of this piece: My new lens is a Raynox DCR-150, otherwise known as the Macro/Close-Up Conversion Lens. Here it is on its own (left photo) and mounted on my Pentax 55-300mm zoom lens (right photo):

The DCR-150 comprises two primary elements: a compound diopter and a threaded adapter with spring arms and a clamp. You can see both of these in the left-hand photo below, along with the separate 49mm UV filter I added to the package. Assembling the lens is a snap. The diopter screws into the adapter—see the right-hand photo below—and the assembly is then mounted on an existing lens in much the same way as you’d mount a pinch-clamp filter cap. (The DCR-150 can be used with any lens taking a filter sized between 52mm and 67mm.)

How does it work? Put simply, the DCR-150 adds a macro capability to your existing lenses, allowing you to get as close as eight inches to your subject. Here’s an example of what it can do. First, I photographed some European larch cones with my Pentax 55-300 mm telephoto zoom, shooting at 300 mm:

This was taken without a tripod, and I haven’t cropped the image. (I’ll explain the white box at the top in a minute.) Using the telephoto, I couldn’t get any closer than 55 inches. Now compare that first shot with a second, taken using the same lens after I’d fitted the DCR-150 converter:

As before, I held my camera in my hand, and I haven’t cropped the photo. (Both shots were made at ISO 100, too.) But what a difference the DCR-150 made! This time, my lens was only eight inches from the subject—so close that I had to zoom out to 77 mm in order to capture an entire cone in the shot. Then, when I zoomed back in to 300 mm, this was what I got:

It’s a picture of a “spur shoot,” about the size of a wizened pea. You can see the edge of one in the white box in the first shot of larch cones.
And now, since spring is in the air, how about a picture of a lilac bud?

Once again, the shot was hand-held and uncropped— and I kept the zoom at 300 mm. Pretty impressive, don’t you think? The DCR-150 may not equal the performance of a true macro lens, but it’s easier to shoehorn into a crowded camera bag. And it’s a lot cheaper, too. So you can expect to see more close-ups on these pages in future, as I go in search of the secrets of the small world.
