What first lense would you suggest for traveling photos, shooting mostly beach whole body photos? Not too big and heavy. Maybe some what could do the blurry backround effect as well? Still deciding which camera to buy so just wondering if the same lense will always fit to all sony mirrorless cameras. But most likely for a7 II or a7III or a7rIII or a7 6000. And should I get the kit lens as well or thats just waist od money and should buy right away some better one. Or kit lens plus the better blurry one?
