The Tiffen Series 9 Split-Field 2 Filter consists of a close-up lens cut in half. Half of the filter is a close-up lens while the other half is open. It is available in magnifications ranging from +.5 through +3.
A macro shot of a rose with an old woman in the background? A close-up of a rock with a mountain range in the background? Tiffen Split-field filters give you the freedom to achieve these kinds of effects.
With this filter, one-half of the photo receives a close-up effect while the other half is normal. In this way, it is possible to have both very close and far subjects in focus at the same time. Or, one-half of the picture can be out of focus for special effects. Commonly used for floral and landscape photography where sharpness near and far is important.
