Hi everyone, I would like my Alpha cameras (A6100 and A6400) to restore the focal length setting of an attached power-zoom lens (e.g the SELP1650 kit lens) every time they wake up from energy saving sleep mode and, preferably, every time they are turned on. Unfortunately both cameras seem to reset the power-zoom focal lens to the widest zoom position at every wakeup, so I have to check and adjust the focal length setting every time I bring the camera to my eye, which is detrimental to my shooting experience. I wasn't able to find any menu option for enabling the camera body to remember and restore the focal length of an attached power-zoom lens after a power cycle: can anybody provide some insight? Thank you in advance! Paolo -
Ok.. so i have a A6400 which has an APS-C sensor.. I use a range of lenses of which include both full frame and crop sensor designed lenses.. I know using a full frame lens i get a crop zoom of 1.5x .. so for example my Sony FE 50mm becomes a 75mm, my Tamron 70-300mm f4.5-6.3 DI III RXD becomes a 105-450mm Now.. if i use a aps-c lens.. i get the exact mm yes ? ie.. if i use the Sigma 56mm f1.4 DC DN .. this IS a 56mm on my A6400 as the DC denotes the lens was made for APS-C sensors and it even has the aps-c cut out on the back of the lens. Do i read this right ? .. or do i still have to put a x1.5 35mm zoom in effect.. so my 56 becomes an 84? This is something that has always confused me... Can someone clarify just what mm i am getting using a dedicated aps-c designed lens on a aps-c sensor please! -
I have an OM 135mm lens and 2x tele-converter, giving me a lens of 270mm focal length. The manual focal length settings available in camera jump from 250mm to 300mm. Should I choose the higher or lower focal length to get the best results at 270mm? I have asked Sony, but they were of little help.
