I originally posted this to the macro forum of DPReview, but got no replies, so I'm posting it again here...
My fiance is a hardware engineer, and is trying to convince his boss to get a DSLR with macro lens to take pictures of circuit boards and components on the circuit boards in order to troubleshoot problems. The requirements are these:
Important criteria:
Can achieve manual focus accurately.
Inexpensive-- the budget the boss gave was $350, though I imagine that is probably too low.
Can produce a decent picture of something like
this in enough detail to tell whether all of the pins are soldered correctly.
Can work in indoor light without a tripod or a hotshoe flash (unless you all feel that is absolutely necessary to get decent results.)
Not-so-important criteria:
Superb image quality. He needs to diagnose problems, not make fine art.
Long battery life.
Build quality, as long as it's sturdy enough to survive a normal life.
Weather sealing.
What camera/lens combo would you all recommend? Obviously we are all big fans of Pentax here, but it doesn't necessarily have to be Pentax. Thanks!
