I’ve been snookered in my attempts to find a decent, repeatable way to get my new 24mm to shoot some technically difficult shots by not having the ability to preset the lens up to take advange of hyperfocal distance. Prez laughs at this because all the ‘old school’ gear that he has, all have quite detailed and wonderful crafted scales on the aperture ring. But ever since NIKON guilded that ring to go to the G series(guilded) and incorporate electronics for automation … the capability has to be figured out another way for the shooter, who wants more than automation.. and wants to craft his/her images….
The setup,
Lense is 24mm @ f/16, near distance ~2 feet, far distance: infinity…formula results is to manually set lens focus at 4′….. (see below app screenshots)
The problem, there is no 4′ marking on lens…(the max marking on the feet scale is 2.5′) and there is no focus target available at the four foot length.
The Solution:
It dawned on me this weekend while coming across this problem again….. This time when I checked my cameras scale, I noticed that the meter scale ended at 1 meter, (where as the foot scale ended at 2.5′). Knowing that a meter is ~3.3, I manually set my lens so that the 1 meter lined up, just to left of the lens scale marking. I took the shot and wallah, the Image was sharp from 2′ to infinity……
Just wanted to pass it along, I’ll be checking this out on some more over time and will also see if this idea is useful on other lenses……
As you can see from the information, if you can set your lens focus lenght at 4 feet @ f/16, you’ll be able to go to go for just about any near to far limit situation and have your Image sharp thouought, not wickedsharp…because you do loose some crispness relying on HFD…….
