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
How does the soft-spot effect differ from a standard soft-focus filter?
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.
What additional accessories do I need to use this filter?
You need a Cokin A-series filter holder and a compatible adapter ring sized to your lens's filter thread. Both are sold separately.
What material is this filter made from?
It is made from Cokin's optical resin, which is ultra-light and shatter-resistant — significantly lighter and more durable than glass equivalents.
Can I combine this filter with other Cokin A-series filters?
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.
Is the centre spot fixed in size or adjustable?
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.
