Hello i have purchased Canon 7d only for short film shooting.I use analog camera for taking photos so i am not going to use Canon 7d for photography.

 

I am student so my budget is limited and i can buy only one lens for shooting movie.That would be useful if i purchase one sharp zoom lens and of course considering x1.6 crop factor.

 

So which lens do you suggest me? ( one important thing for me  is that it must be f.2.8 )

I own a canon 24-70 f2.8 that i use on a 5D, it's a great lens, it may result a bit long considering the crop factor, or not, depends on your needs.

hope it helps

Thank you.I prefer wider angle than long zoom lens. I am considering

 

-Tamron 17-50 f2.8   non vc version(because i am mainly using tripod)

 

or 

 

-Tamron 28-75 f2.8

 

I dont know which one is sharper.What do you think about these two?

Have a look at this comparison tool. Both lenses have strengths and weaknesses, but it's hard to compare them across their focal lengths as they are so different. Neither looks terribly sharp at any focal lengeth at f2.8. Centre sharpness never looks that bad though. Away from the centre it looks like they can both get pretty soft. To be honest, clicking through the stops and focal lengths I struggled to find any sweet spot.

Actually I take that back - the 15-50mm looks like overall the better performing lens - particulatly at 35mm. NB - the above comparison is with the mkii version.
