K5ii no 1/180th Shutter option ?

Hey guys, thanks to you i recently discovered that my K5ii's flash sync speed is 1/180th! However i cant seem to get that shutter speed on camera. A fairly odd thing.

Camera basically jumps from 1/160th to 1/200th. Is there a way to change shutter steps in menu like iso ?

A setting of 1/2 EV steps should give you 1/180th sec. The EV step setting applies to ISO, f-stop and shutters speed as well as compensation settings.

This, you apparently set the exposure steps in thirds of stops instead of half stops. It can be useful at times, not so with flash.
That's one little more reason to get 1/250s flash sync... it's on a full stop, not on a half stop. Marginally more convenient, but still...

Not sure if these other members have a K5 ll models but it has nothing to do with setting your EV steps to 1/2 instead of 1/3 using these cameras, other models it may. I can get 1/180 using either one on my camera when using a flash and ISO 100+. From my experience what it does entail with these models, or at least on mine, is the Expanded Sensitivity setting in the custom menu. So with that selected ON, allowing for 80 ISO and you have your ISO Sensitivity AUTO Setting in your record menu selected in a range from 80 to the max or whatever range, when you select an 80 ISO with your flash instead of the standard ISO 100+ your camera at times will jump from 1/160, may briefly show 1/180 and then go to1/200. Sometimes it may fluctuate between using 1/180 and 1/200. With these cameras selecting an 80 ISO can give you the equivalent of a 200 flash sync speed. Although it will show as 1/180 in your info.

So if you want to change it form going to 1/200 either turn off the Expanded Sensitivity or just use ISO 100+.

it's great to know this, thanks a lot !

Look at the speeds for 1/2 stop (step) settings:
Shutter speed | Ober Photography Tips


ImageLiner.blogspot.com: Fractional Shutter Speed and Aperture Chart


K5II specifications from English manual page 317 : Shutter speed: Auto: 1/8000 to 30 sec. Manual 1/8000 to 30 sec. (1/3 EV steps or 1/2 EV steps), Bulb

When set to 1/2 EV steps 1/180th sec will be an option when using the eDial to set the shutter speed.

1/2 EV steps may not be as useful to many shooters but it is the default setting on some of the bodies.

I am well aware of sync charts but it is really helpful your posting them.

Yep it says this. So it shows capable of doing both 1/2 & 1/3 steps most modern cameras will and are selectable so I don't get your point in showing this.. But I do stand slightly corrected, I mainly use 1/3 steps with my camera. Setting it on 1/2 mine will go to 1/180, per your post and charts, but wont go to 1/200 even using ISO 80 or at least it didn't when I tested it. Given that then it wouldn't matter if one were using Expanded Sensitivity or not as long as one uses 1/2 EV it will be limited to 1/180. I like mine at 1/3 showing going to 1/200 at ISo 80 so I will keep it where it is and use my other ISO's accordingly. Granted this is not an option with any other Pentax cameras that do not have ISO 80 capability and setting them on 1/3 EV will limit them to 1/160 sync as indicated in your posted charts.

Yep it will and at 1/3 EV 1/200 showing will be an option if one is using ISO 80 and 1/180 at ISO 100+.

Except that regular flashes (i.e., non-HSS flashes) won't be fired at 1/200s anymore.

Contrary to your first post, the availability of 1/180s (i.e. the sync-speed) as a shutter speed has everything to do with the EV step chosen and nothing to do with ISO settings.
