This entire video is utterly confusing. First off - 70% of the screen footage is Google Maps. The closest the Sony rep comes to explaining why is 'meta data'. Then the software - it's 3 parts - 1) importer. Eh? Surely you don't want to re-invent the wheel. 2) prepare. Does it mean color correction? In/out marking? I am just confused about what this is ACTUALLY doing 3) Edit. How does this compare with Sony Vegas (from the same vendor)? What's the point of the software? It looks a bit like those 90s software packages that came bundled with your camera. Surely not something that need such hype? Listen up Sony - spend your dev budget on fixing the stability bugs in Vegas rather than building yet another half assed 'productivity' suite...
I started with a Canon 550D (Rebel T2i) and had the exact same question. After reading some articles on the Internet I bought a Canon 50mm F1.4. Great lens but I wish did my homework better and read about crop factor. A 50mm lens on a cropped sensor like the T3i (anything other than full frame is cropped) ends up to be more like a 80mm lens. To get the 50mm look I bought a Sigma 30mm F1.4, It ended up being one of my favorite lenses (and still is).
I suggest looking at a prime lens with a large aperture. It forces you to do two things. 1) Because it's a fixed focal length you have to think about your framing and shot a little more 2) When you work at large apertures you'll learn to work that focus ring (and appreciate the skills of a focus puller). A large aperture prime also gives you more flexibility in terms of depth of field and low light capabilities.
Another consideration is EF or EFS - if you are going the Canon route. Investing in EFS lenses means you can't use it on a full frame camera (like the 5D etc). Also consider USM vs STM - the latest Canon STM lense are great when you want to use continuous auto focus (but don't sweat it - you'll learn to do without it). Lastly - if you are serious about this hobby - take it from me - rather save a little for a quality lens than making an impulse buy.
