if the camera has geared movements, that would be a definite plus.
if not, it can take longer to get the proper movements down to get things you want in focus/out of focus....
if you're in the market, you could get a sinar p2(fully geared movements), and lenses could be gotten for a small amount more.
its your call though. many have stated on here that a sinar p2(originally designed for film), doesn't meet muster to the needs of a digital-only shooter. because the movements aren't "fine" enough for the digital sensor, they state that it is somehow unusable.
cambo makes some terrific cameras, but if you really want to shoot product/food, and time is of the essence, then I'd recommend getting the Sinar. but, in the end, different strokes for different folks...
do you have a rental house near you that you could rent an hts from? beats buying one, to find out you hate it
I personally know a few people who shoot food/products with a Sinar P2, all but one are digital only now, all shot 4x5 film back in the days. one guy's P2 is older than me . just shows you how robust these cameras really are when treated nicely, and serviced regularly(every 3-5 years). the geared tracks go out on the older ones, because Sinar used plastic gear tracks in the original ones, but replaced the plastic ones with brass tracks I believe in the 90s, due to excessive wear.
see if you can find someone near you who has a p2, they're great cameras, and plenty of people are letting em go, damn cheap! renting lenses will be easier too, since most rental houses rent lenses on sinar lensboards vs cambo ones.
