My brother-in-law currently shoots with a Nikon Coolpix 5100 and he complains about the shutter lag (by which he means to include auto-focus delay). His complaint is consistent withe the review of the camera on DPReview and so he asked me what compact camera he could buy (about the same size as the P5100) that would shoot as fast as the Nikon D40 DSLR he has borrowed. I told him that I did not think any compact camera would shoot as fast as even an entry-level DSLR, but I'd try to find out. Any ideas? (He isn't concerned about subtle differences of image quality, Canon v. Nikon v. Fuji, e.g., and I imagine that any fast compact will be high end and have IQ that would satisfy him.) Thanks in advance.
