Hi: I was hoping for some feedback. I have been using a Canon T1i with a stock zoom lens for my photography with some decent results. I primarily shoot bands in clubs and family events. I'm not a professional photographer but a serious hobbyist. I am looking to upgrade to something that suits my current requirements plus can be used to make music videos and short films. I was looking at the Sony a7s ii for it slow light capability. The issue I have is that its really expensive and there aren't too many lenses for it. Yes you can buy adapters, but then you aren't able to use the native features of the Sony. The other option was Canon 5D MKIII which has a really good reputation for an all around camera and has been the defacto for many people for years now. Some are looking for the MKIV which is to have 4K internal recording. Canon of course has tons and tons of lenses and a proven track record. Even in the comparisons, it comes out as a better overall camera but the Sony far exceeds ANY camera in the low light department. So what's your advice ? Go with the Sony a7s ii coz it will pay off down the road for short films and band pics in dark clubs and its Slo Mo and internal 4K for a hobbyist like me OR Save some cash, get the 5DMKIII and spend on lenses and lighting props and such which will pay off in the long run ? The analogy which I keep running into is: Buying a Steve Vai Jem won't make you Steve Vai.
