B+W 72mm Close-Up +4 (NL4) Filter – FIlter Close Up BW

B+W 72mm Close-Up +4 (NL4) Filter – FIlter Close Up BW

Overview

The B+W +4 diopter close-up lens is the right power for additional close-up range with the 50 mm lens (up to approx. 1 : 3) when the B+W +2 close-up lens has reached its limit. This is the maximum power for telephoto lenses with focal lengths of 85 mm (to approx. 1 : 2.1) and 100 mm (to approx. 1 : 1.9), but you should stop down to at least f/8. With a 35 mm focal length, pass straight on to the B+W +5 close-up lens.

Features

• Especially useful for simple close-ups
• Fascinating shots of flowers, insects, and small objects
• Suitable for analog and digital cameras
• Low-cost, straightforward entry to close-up photography

Close-up lenses
As clearly illustrated, the stronger the close-up lens, the closer you can get to the subject with the same distance setting and the larger the image you can obtain. A longer exposure time is not necessary.

B+W close-up lenses can be combined, but for quality reasons and to prevent vignetting no more than two lenses should be mounted over each other. The values are simply added together.
