Hi Everyone,i just have a quick qurstion if i may, i just purchased the tamrom 70/300 zoom lens for my KR, my problem is and as i'm also new and it may just be me not having a clue what i'm doing. I placed the tamron lens on the body and then set the lens to between 180 and 300 then turning on the macro switch,the problem comes when i watched a youtube tutorialand the guy did the same but he pressed his af button to zoom in and then move his foacal point,well when i do this the lens zooms all the way in,then back out,it wont focus,if i then manually change my aperture on the lens from auto to manual and set the lens to auto focus the camera won't do anything,the picture capture button does nothing and its almost like the camera has been switched off, i cant seen to have the macro lens on and get close as it can't focus and there i was thinking the whole idea was with macro was to get nice clear ,crisp images,i've only had this camera 6 weeks and i'm so done with it already,my point and shoot compact produces much better results all the time,i wanted to learn photography but it seems so complicated its just causing me stress and i thought it was meant to be relaxing,i've not taken a single picture yet worth saving and have spent in the region on£1200 quid,even got ps cs5 but can't use it either as i have no pictures,anybody wanna buy a lovely big beginners kit,complete with slingshot bag and lenses,tripod,monopod....all sorts...this stuff is all new with receipts
