The other issue with K/M/S lenses (at least on the -DS) is that the

like I need an
external flash
Yes, if you want flash exposure automation with these lenses on the
DS body, you need to use an external flash unit. Pentax-dedicated
units can use the body's TTL flash metering, non-dedicated flash
units with their own auto-flash sensor work well too.
The DS built-in flash works fine as a full-power manual flash,
though: just set the aperture per the guide number table in the
manual (page 149), and be sure the shutter is set to 1/180 sec or
slower.
