Both the Diffusion and Duto are soft-focus filters.
The Duffuser gives an overall soft effect while the Duto soft effect usually leaves the center sharp.
Both are particularly effective in portraiture and commercial photography.

I was shipped a scratched filter despite confirming with sales that the glass was pristine. I had to pay to have it shipped back (second time this happened). I made a simple request to be reimbursed for shipping since the defective merchandise was not my fault. I had no end of hassle to simply get refunded the $4 for shipping and do date, still have not. I would not recommend purchasing products from Adorama (at least used products) as the customer service is terrible. If you have any issues or need to return items, you'll spend an undue amount of time and hassle for a refund.
