gud purchase bro!
its not a semi dslr
its Pro APSC DSLR from canon!
7D is though now 5 years old but still one of the best in canon when it comes to sports, wild life and action photography!
with that package its an excellent deal.
u dont need 256GB CF card, instead buy 3 or 4 CF Cards cause if one gets damaged u dont loose everything (just an advice with self experience)
also buying 32gb but 1000x CF card will make u future proof.
About lenses, choose wisely. If u r a wild life shooter then must get Canon 400mm f5.6 L, nothing short of it.
It doesnt have IS but if u want IS in same focal range then 400 mm IS will set u back like $3000+
so choose very carefully. Dont be a miser person when it comes to lenses cause lenses r everything, its like eyes of ur camera, if the glass is cheap then no matter how great a camera is, images will be like washed out, out of focus, n no details.
For inspiration, follow this guy. One of the best in Pakistan with most cheapest wild life photography gear.
