With- and without Raynox DCR-250

This blog post is a simple demonstration of the effect of adding a Raynox DCR-250 close-up filter to my Panasonic Lumix DMC-FZ300 24x superzoom bridge camera. Both photos are full-frame, that is, uncropped.

Without Raynox

A set of keys for my apartment at The Beacon of Groveton (BoG) is shown in the first photo. I chose keys for the subject since most people are familiar with the typical size of door keys; the slightly smaller key (far right) is a mailbox key.

The camera lens was set for “Wide Macro,” with a focus range from 1 cm (0.39 in) to infinity. A Canon MT-26EX-RT Macro Twin Lite was attached to the front of the camera lens using a new Sensei PRO 52-58mm Aluminum Step-Up Ring to adapt an old Canon Macrolite Adapter 58C (58mm) to the lens. My Raynox DCR-250 close-up filter wasn’t mounted on the front of the MT-26EX-RT.

With Raynox

Part of a single key from the set of keys is shown in the last photo. The same key is shown on the far left side of the first photo.

For this photo, my Raynox DCR-250 close-up filter was mounted on the front of the Canon MT-26EX-RT Macro Twin Lite attached to the camera lens.

According the B&H Photo Specs page for the Raynox DCR-250 close-up filter, its magification is 2.5x. The actual magnification might or might not be 2.5x, given the fact that the camera lens was adjusted for slight telephoto zoom in order to eliminate the vignetting caused by mounting a 43mm filter on a 52mm lens. All of that being said, the last photo clearly shows the magnification is increased dramatically in contrast with the first photo!
