Q. I'm not quite sure what to purchase and would enjoy help considering quality and budget, i'm looking lenses that i'll be able to get a very thin depth of fields as well as full focus wide angle shots.
Answer
I would consider Canon EF 24-70mm f/2.8L USM Standard Zoom Lens for Canon SLR Cameras
EF mount; standard zoom lens; Comes with Lens Cap E77U, Rear Lens Cap, Lens Hood EW-83F, Soft Lens Case 1219.
Ultra-low Dispersion glass with Fluorite elements; inner focusing ring; full-time manual focus; aspherical lens
24-70mm focal length
f/2.8 constant maximum aperture
UltraSonic Motor (USM) AF actuator

What is a good first Canon lens for my canon 7D to shoot video with?

I am a filmmaker, and I am investing into DSLR lenses. I also want to use this lens for photography.
Let me know. I was thinking to get the Canon 50mm f1.2 or f1.4. What do you think?
Answer
I hate smart people who think that being a film maker necessarily involves silver hallide acetate.
JimA doesn't have a video DSLR and so is the wrong person to answer this, as bourne out by his recommendation of a superzoom lens, the quality of which can be most kindly described as mediocre.
Sorry Jim, it's one thing trying to help, it's another racking up points on subjects where you've no useful knowledge (and being facetious into the bargain)
ANYWAY
Back to the question.
I would recommend a constant aperture walkaround, either Canons 17-55 f2.8 IS EF-s lens (very expensive) or Sigmas version, even the Non-IS version (at less than half the cost of the canon) just make sure it is the constant f2.8 aperture version.
With video you can't shoot below 1/30th and are better to shoot at 1/50 or 1/60th, so an f2.8 constant lens gives you an extra 1-2 stops of light over the zoom range compared to a ramping aperture lens.
The max f2.8 also brings the 7Ds AF system to life, particularly the centre point with its dual cross -axis phase detection.
Fixed lenses are less flexible and very fast short tele lenses (the 50mms become more like an 80mm lens on an APS-C 7D) are very tricky to keep in focus. They are great for effect but not easy to live with for general use.
If you really want a 50mm then I would get the cheapo f1.8 version, and get one of the constant aperture walkarounds.
I would never part with the cash for the f1.2 50mm. It's not worth the cash optically. The f1.4 is equal better accross most of the range.
