I've been doing food photography for the past few months now and I've been VERY happy with the K20D and the DA Limited lenses so far.
GREAT optics. I mean fantastic optics. Helluva sharp and my shooting partner (who uses Canon) is always astonished at how good these tiny lenses are. I started out with the DA40 and eventually got the DA21 and DA70. I also have the DA35 but somehow I don't find myself using it much, I keep forgetting to put it out.
The light weight and compact size of these lenses have been great. Mounted on my Manfrotto 055 + Markins M10 is quite overkill (coming from a Nikon f/2.8 system) but my whole setup is rock solid and really easy to adjust.
The K20D's body has been fantastic. I love the viewfinder paired with the KPS U-13C 1.3x viewfinder magnifying eyepiece. The sensor (and lenses of course) has been really bringing out the detail, which is what food is all about = details!
Only gripes so far are the relatively crappy computer tethered shooting, and also the slow flash sync speed (max 1/180). Other than that, very happy with the system.
I actually use the Live View a LOT! Once you figure out its weaknesses and quirks, it's helluva useful. I hook up my camera to a portable screen/DVD player and set my camera on a tripod, then carry around the screen while tweaking/fixing the table setting using Live View. I can instantly see what I move on the table setup, instead of (1) adjusting stuff on the table and (2) going back to the camera to look through the viewfinder AGAIN and AGAIN.
I can't stress how excited I am should Pentax improve the Live View with a better LCD screen on the body (zooming in for focus checking would be so much better) and implement HDMI.
Shooting food has been such a great experience so far and a REAL challenge in lighting. My lighting knowledge has been really growing with shooting food. So is my attention to detail! I can't say how many times such a little detail could make or break a photo, little things like a tiny ingredient out of place, the way a glass is positioned (rotation-wise), how adding a tiny splash of light using a tiny reflector could really enhance the shot, and so much more.
I'm relatively new to food photography (started November 08) and here are some of the photos I'd like to share
