Overview

The Cokin A188 Softspot filter belongs to Cokin's long-established Creative Filter System and produces a distinctive effect: the centre of the frame retains mild diffusion for a gently softened look, while diffusion increases progressively toward the edges and corners. The result is an image that naturally guides the viewer's eye to the subject at the centre while surrounding it with a dreamy, almost ethereal quality. This makes the filter particularly well suited to portrait photography, where it can smooth skin tones and soften distracting backgrounds in-camera without post-processing.

Manufactured from Cokin's proprietary optical resin, the A188 is notably lighter and more shatter-resistant than comparable glass filters, a practical advantage when working on location or switching effects frequently. As part of the A-series (S-size) system, it slots into a modular filter holder that attaches to your lens via an adapter ring — both sold separately — and can be combined with other A-series filters for layered creative effects. The square format allows you to slide the filter up, down, or sideways within the holder, giving you some control over where the sharp centre falls relative to your composition. For photographers who enjoy crafting effects in-camera rather than relying solely on software, the Softspot offers a tactile, immediate creative tool at an accessible price point.

Pros & Cons

👍 Pros

  • Creates a naturally focused centre with dreamy peripheral diffusion in a single filter
  • Ultra-light optical resin construction is shatter-resistant and easy to handle in the field
  • Compatible with the full Cokin A-series modular system for stacking with other creative filters
  • Sliding the filter in the holder allows some repositioning of the soft-spot effect

👎 Cons

  • Requires a separately purchased Cokin A-series filter holder and adapter ring to mount on a lens
  • Fixed soft-spot pattern offers limited control over the size and intensity of the diffusion zone
  • Optical resin surface is more prone to scratching than glass filters and needs careful handling
  • A-series size suits smaller lenses; larger front elements may require the larger P-series system instead

Frequently Asked Questions

A standard soft-focus filter applies diffusion uniformly across the entire frame. The Cokin A188 Softspot keeps the centre of the image relatively sharp while progressively increasing diffusion toward the edges, drawing the viewer's eye to the subject in the middle.
You need a Cokin A-series filter holder and a compatible adapter ring sized to your lens's filter thread. Both are sold separately.
It is made from Cokin's optical resin, which is ultra-light and shatter-resistant — significantly lighter and more durable than glass equivalents.
Yes. The Cokin A-series filter holder can accommodate multiple square filters simultaneously, so you can stack the Softspot with colour, graduated, or other creative effect filters.
The soft spot is fixed on the filter itself, but you can shift its apparent position by sliding the filter within the holder. Changing focal length also affects how the transition zone appears in the final image.
