So ive been reading up on the hyperfocal Distance stuff.
I get the principal of it ok but how to apply it to good effect in real world situations.
Been looking here and using this calculator.
So for example, ive just picked up the Tokina 11-16mm f2.8.
If i set it at 11mm, f5.6 and set focus to 10 ft i should be good focus wise from 2.6ft to infinity as i understand it using their calculator?
Should i really convert the numbers to a 1.5 sensor crop factor of the D90 to get more accurate results, so 16.5mm in this case?
Is it best to manually focus using this technique as if you used the AF i guess you would have to focus on the ground or some object at the chosen focus distance and then lock it off.
Would there be from experience a good range of f numbers to stick to to keep other optical lens effects under control?
