I believe sony dslr of that era were the first ones to have live view and it was pretty terrible. What about tethered shooting?
quoting from pentax forums.
"Proper' tethering isn't supported on the K200D, in the sense of 'remote display at full resolution and with remote control of the camera'. But 'pseudo' tethering CAN work fine three ways with the K200D. And it will achieve exactly what you have asked.
I've verified the first two methods , the 3rd is a guess.
(1) Make sure 'Instant Review' is enabled. Then connect the AV cable supplied in the K200D box to your K200D and your PC or an external video monitor/TV. Any photo you take is then instantly displayed on the external video display, for the period of time you have selected for instat review.
(2) Make sure that 'Digital Preview' is enabled. Then connect the AV cable supplied in the K200D box to your K200D and your PC or an external video monitor/TV. Any photo you take is then instantly displayed on the external video display for as long as you choose, and if you like how it looks you can choose to save it, discard it etc, as per usual.
(3) via something like an Eye-fi card. I think it probably works on the K200D.
(1) and (2) have limitations - the output image is only at standard definition PAL or NTSC resolutions, and requires that you have a device with an AV input, but it works."
