Sigma DP1 Speed

This image had the green corner syndrome. I repaired it in Photoshop, but it was troubling to have to fix what was one of the better photos I captured yesterday.

While I think the online community has been impressed with the DP1’s image quality, everyone remains interested in the camera’s operating speed. Despite it’s image quality, the electronics are those of a typical compact digital camera. Autofocus is typical, being fast enough in good light and slow when it’s dim, but without the quick “snick” of a DSLR. Once focus is locked or if set to manual, the shutter lag is not really noticeable.

I need to do a better job of watching ISO and shutter speed when I shoot aperture priority. With the D300, Auto ISO lets me set a maximum shutter speed and quickly ramps up. With the DP1, there’s no indication of the ISO that the camera has set and no way to control minimum shutter speed. The manual doesn’t provide any real detail on how auto ISO works, so for now, I’m trying to watch shutter speed. Choosing ISO may be a better way to go.

I'm an MD, PhD Neurologist who left a successful academic career on the Faculty of The Johns Hopkins Medical School to develop new treatments in Biotech and Pharma. I became fascinated with how people actually make decisions based on the science of decision theory and emerging understanding of how the brain works to make decisions. My passion now is this deep explanation of what has been the realm of philosophy, psychology and self help but is now understood as brain function. By understanding our brains, I believe we can become happier, more successful people.
