![]() ![]() Rather than assuming resolution for an 8x10 is appropriate, you might want a 16 x 20 viewed at the same distance. Most animals move very quickly and have long faces (-vs- a human) - so we need reasonably large DOF to achieve sharp images - almost 90% of the wildlife shots I have published are take with apertures wider/less than f/10 - and almost all taken down to f/6.3 were large animals, animals with long faces or shots where I wanted the surroundings in focus as well - elephants, hippos, zebra, antelope, warthogs, and of course lions near to us and leopards & lions up trees.Īs a shooter one has to experiment to see what works best for you and the subjects you shoot in various light conditions - take multiple shots of each using a range of settings - a banker wide open high shutter speed and then try more closed down/lower speeds to find if a better setting can be found in the light you have available at the time.Īs we consider higher resolution sensors and larger prints, you might choose a smaller CofC or consider a wider aperture limit. Wildlife shooters (that probably includes me) have less choices - shooting a Z9 with 600/4 gives a DOF of 0.37m 20m and 1.48m at 40m when using f/5.6 and 0.5m and 2.1m respectively at f/8. Almost always in the range f/5.6-f/8, rather than wide open or more closed down. Now with focus stacking so easy to automate - most of us shoot at the sharpest aperture on each lens/body - when we can use this technique. AND 100mp on a Medium Format - these having both much larger sensors and much larger diameter lense mounts).ĭiffraction is both real and has a visible impact - more/earlier on higher resolution sensors than lower ones - but is the impact of diffraction more than having an overly ultra narrow depth of focus? This is one of those tradeoffs.Ī great many landscape and product shooters use lenses stepped down to f/11-f/16 or even narrower. You could run the numbers using one of the online DoF calculators but in practical terms I don't think those varying DLA numbers make a practical difference in the field though they may help with decisions like how far to stop down when running a focus stack sequence.Ĭlick to expand.There is a reason why, before considering multishot pixel options, 62 mp is probably the highest pixel density we will see on a 35mm sensor size. For starters to achieve the same DoF for the same field of view when shooting from the same position the crop body camera would be opened up relative to the full frame camera and of course the crop body camera's lens would be zoomed out (or a wider angle lens used) to frame the same scene. I suspect the real world impact, especially comparing a full frame to a crop sensor camera will be negligible. Shooting scenics with wider angle lenses in which case for framing the same scene from the same location I'd use a wider lens on the crop sensor camera and to achieve the same DoF on the scene that lens on the crop body camera would be opened up wider and likely wouldn't push the DLA any harder than the FF camera stopped down further to achieve the same DoF for the same framed scene Shooting wildlife or portraits with long lenses I'd generally shoot wide open or very close to it with either a full frame or crop body camera and likely not reach DLA (though I guess when shooting something like a wide open f/11 lenses that are beyond DLA limits for the camera in question which may be a good reason not to use these lenses on the highest pixel density cameras) You could run the numbers using one of the online DoF calculators but in practical terms I don't think those varying DLA numbers make a practical difference in the field though they may help with decisions like how far to stop down when running a focus stack sequence.īasically I see a couple of common nature photography scenarios and don't see this making a big difference for either of them: ![]() Click to expand.I suspect the real world impact, especially comparing a full frame to a crop sensor camera will be negligible. ![]()
