Hi based on my same question and advices here i understand we would have two options to set 70d gear for covering all peruses: first crop-lens-combo including 50 f1.4 + 70-200 f4L is + 60 f2.8 macro. Option 2: 24-70 f4L is + 70-200 f4L is + 100 f2.8 macro. Some professionals believe that ff lenses are not responding very well on apc crop cameras like 70d and some say its no problem you can us ff lenses on 70d just you need add a wide lens with lower focal range 10-20mm to your gear. And still even i am confusing Smiley Happy any pro advice?

I understood and appreciated yr approval on option 2. Just my technical question now for 70d is: regarding ef 10-20mm 3.5-4.5 usm: as u know on crop sensor camera i need wider aperture in my set; Why did u selected f3.5 rather than a lens with f2.8 or 1.8 or 1.4? Sorry for asking!

"Why did u selected f3.5 rather than a lens with f2.8 or 1.8 or 1.4?"

 

Because there is no f2.8 or f1.8 or f1.4, 10-22mm lens from Canon.

EOS 1DX and 1D Mk IV and less lenses then before!

don't i need any wide aperture in my set like f1.4 or 1.8 or 2.8? since these apertures are in some lenses 40, 50, and 85 mm which will be 1.6x on my aps-c camera, as i understand you want to say that i need in my lens-set, a lens with minimum "mm" like 10-22 although the aperture is 3.5. right?

Except for a few fairly specific applications, wide-angle lenses aren't of much use indoors. They distort a lot, and they subtend an angle that most speedlites can't handle. Since they're used mainly outdoors, they don't have to be very fast.
