Shooting A 35/1.8 Lens Totally Stopped Down

I decided to do an experiment shooting a Nikon 35/1.8 lens totally stopped down to f/22...on a Nikon D7500. I used aperture priority and auto ISO.

I recently posted an experiment using the same setup while shooting totally wide open at f/1.8.

One of the early things I found, especially in shade, is that the shutter speed dropped to 1/25, making it more difficult to get sharp photos.

I opened the aperture to f/16, then f/13. This dropped the ISO to a better area.

I am posting photos that I like from the shoot.

In the future, if I want a broad depth of field while shooting handheld, I will probably go with f/11. Some will likely say they already knew this without this experiment. I am aware that f/8 to f/11 is the most commonly recommended area for landscape photography.

I hope someone will be able to enjoy at least one of these photos taken yesterday at Vines Park, Georgia.

You also adjust your iso to get your shutter speed up as you increase your DOF.

Nothing wrong with these images. Some photographers stay away from f22 because of refraction. I do not go to f22 often but if it is important to use that f stop for a shot I would certainly use it.
Refraction is very well controlled today and many in camera software take care of that. Editors do the same thing. Sharpness depends more on what we do than what the lens or camera does.

If you study depth of field it could surprise you how sharp images look with the lens wide open. Many portraits are shot that way but even landscapes could look awesome if shooting a distant scene. The distance from camera to subject is important in that regard.
Using f11 and f8 is common practice with many types of photography. Have you heard "f8 and be there?" Learn depth of field although both of your experiments I am sure have opened your eyes.

I particularly like the last image.

Beautiful photos, but the high ISO makes the noise too much IMHO! I would have used a tripod and much slower shutter speed so as to get the ISO way down.

Nice pics - last one is my choice. I would have expected 1/25 to be ok for careful hand holding with IS, which should give you equivalent of 1/100+.

I believe you mean diffraction not refraction at f22

Thank you for your comments and the like. I was surprised that the ISO jumped that high, but as I have mentioned I don’t use these prime lenses that much. The more I learn, the more possibilities I see.

I like them all, but the reflections I like the most

Thank you for the compliment on the photos. As I mentioned in another response, I was surprised by the high ISO numbers, not using my two 1.8 primes that much. I agree that a tripod would solve this issue or a more wide open aperture.

Dean, is it cheating if I really enjoyed them all? That is what happened soI hope not! I am using my iPad Pro at the moment and I don’t see the noise on it apparently. They look great and the compositions are lovely!

Thank you for the compliment and photo choice. Unfortunately neither the lens or camera has IS. For more serious work, I usually use a tripod.

Thank you for the super nice compliment! I do my final editing on my iPad and the photos look OK here. I normally try to avoid high ISO numbers.
