Hi, Hopefully this query isnt irrelevant or this list, if there is somewhere else I should be askingthis please feel free to direct me there.
I´m new to the DSLR wold viathe Samsung GX-10, which is basically a rebadged Pentax K10. I´ve used it mostly with the2 kit lenses it came with and noticed a small oddity but live with it as it didnt affect my overall use, however I have just purchased a Sigma 18-200mm DG F3.5-6.3 and now the problem is more serious as I am effectively unable to use the lens. Before trying to work out how and whom to contact (this was bought online) I thought Id ask those more knowlegable in these areas. Basically, the default setting on the camera is to have the option Use Aperture Ring (Custom2 Menu, 3rd option on the screen) set to Off. However I noticed that mine was set to On; which I might have done when trying to use an old K mount lens a friend let me try on my camera. When I set it to the default value of Off, the auto focus fails to work on the kit lenss and it can only be used in manual mode. I didnt worry too much about this as I just left it set to On and continued to work with it. However when I received my new Sigma 18-200mm lens the other day it would only work in manual mode and this proved to be the case regardless of the setting on the Use Aperture Ring option. So I decided to try and work out if it was the lenses or the camera. My brother has a K10 and I checked his setting it was set to Off and tried both my kit lens and my Sigma on it and they all worked perfectly in the Off setting. Likewise his kit lenses behaved in the ¨odd¨ manner on my camera that mine do. Hence I decided it must be the camera. As I understand it, with my rather limited knowledge; which is basically some very quick learning from various web sites, the lens and the camera exchange information via the contacts on the mount. Could any/some of these contacts be ¨messed¨ in some way so as to be conveying incorrect information and short of trying to get Samsung to fix this is there anything I can do/try to see if I can correct the problem (without invalidating any warranty). I´m figurin gI´m going to have a tough time explaining this to a help desk so just wanted to make sure by consulting those in the know.
