Ever wonder what the real-use difference is between RAW and jpeg on the Sony A580? Check out the crops below. The large image below is a crop from a set-up shot of a newly remodeled kitchen. Although I didn’t use this particular image, I did notice the differences in files when doing some PP. I normally shoot cRAW for everyday jobs, and full RAW for more important stuff. The A580 has no cRAW like the A700 and A900, so I decided to shoot RAW+jpeg because I haven’t messed much with the A580 RAW conversions, and didn’t want to have any surprises in post processing etc.
The A580 creates a fine jpeg along with a RAW image, and I was surprised at the smearing in the fine image. The Sony A580 is very capable for interior photography, (and all photography for that matter), but I wouldn’t advise using jpeg, there’s too much luminance smearing, Sony should allow this to be adjusted, hopefully in a firmware update.
You can clearly see the jpeg is wiping out the cabinet wood grain completely, and the back splash tile has no detail either. Specs for the shot; F/7.1, ISO 200, 1/5sec, 20mm (30mm equiv). No sharpening has been applied.
