Long Exposures

I looked at the K3ii manual online and the K3ii doesn't appear to have the timed bulb mode that the K1 has. Thus timed bulb exposure can only be done manually via the shutter button (in mode 1 or mode 2) or via an external remote timer.

As womble has posted the K3iii appears to have the timed bulb mode upto 20 mins. Looks like the K1, K1ii, KP, K3iii and K70 have the mode but K3 and K3ii don't

Yes, I use the bulb mode and extended timer also, it's a great feature.
