Aperture Settings

Please excuse my ignorance in this question. We have two K30s at home and with two DA 3.5-5.6 18-55mm Lenses. In Manual mode we are sometimes locked out for a going to the MINIMUM aperture setting. Stuck at F4.5 sometimes 5.6, either way I can never set either camera with either lens to F3.5. Been searching the web, searching this forum, unsuccessfully looking for answer. Maybe I am not using the correct search terms. Either way I am looking for answer to this query. Many of my other lenses work perfectly for never been stuck for a min aperture setting.

Any information would be appreciated.

Probably a daft question:- are you checking at 18mm?

The minimum aperture changes based on the focal length - so the more telephoto you've set your lens, the higher the minimum aperture will be. This means that at 18mm zoom, the minimum aperture will be 3.5; at 55 it will be 5.6, and it changes somewhere in the middle. You'll just have to either shoot at a shorter focal length or get a better lens.

Hope that helps!

Thanks Jellinga, that was awesome information. Never looked at lenses properly for understanding that. That was awesome.
