hello .. am looking for a basic janet and john type introduction/insight into using a third party adapter with the q.
an adapter that gives me the ability to use a k mount lens .. specifically a 28-
90mm zoom.
when invited what should I set the focal length to?
should I take the 5.5 x crop factor into consideration?
would I set the fl to 450mm .. the extreme end of the zoom OR 154mm .. the wider end?
alternatively should I set the fl to either 28 or
90mm?
the adapter I have does have a very crude aperture control.
should I leave it wide open and use the aperture control on the lens itself?
do I have auto aperture control available to me? if not .. what should my starting point be? aperture control? shutter speed control? manual?
can I or do I use the leaf shutter? is it electronic shutter control only with a non pentax adapter? do I have any sr abilities? are there no sr abilities?
does the use of a third party adapter limit me to manual usage only?
what are the best settings to use?
anticipated thanks
