The Tiffen 4 x 5.65" CC30M Magenta Filter is a color compensating (or color correction) filter for use when making color balance adjustments. It can be used to alter the color balance of a scene by placing in front of a light source or the lens of your camera. It can also be used to apply color corrections when used in the darkroom with an enlarger or to help pre-visualize color adjustments when viewing prints.

Magenta is the opposite of green and can be used to reduce green tones or casts within a scene or print. This magenta CC30 is more dense than a CC20 filter and less dense than a CC40 filter, and requires a 0.6 stop compensation for normal exposure results.

Tiffen filters are made using ColorCore technology; a process that involves laminating the filter substrate between 2 pieces of optical glass and grinding flat to a tolerance of 1/10,000th of an inch. This filter measures 4 x 5.65" / 101.6 x 143.5mm.

What would be a better fit for this lens?

A: The OP/TECH USA Snoot Boot Wide Body (XXL) will be a better fit, as it is 12 in length. It is made out of neoprene, so it will be able to fit the lens comfortably.
