So I'm trying to learn to use shorter focal length lenses. So I'm curious what can be done with them. So in that spirit:

Show us what you can do with a focal length of 35mm. (We know that on a cropped sensor it's more equivalent to 50mm, but to keep things easy, set your focal length to 35mm and shoot!)

Many cameras (mine included) cannot be easily "set" to a specific focal length (equivalent) ... maybe make it a "maximum focal length of 35mm"? In fact, on my camera the widest it goes is 36mm (what it would be on a full-frame 35mm camera).

I was thinking about that. If it's a zoom lens, you should be able to put your lens at 35mm. I wouldn't want to do maximum, because then we'd get a lot of wide angle. And 35mm really is more what the eye sees, not wide angle.

But I also realize that there's a little creep in the lenses (not literally... I hope! It seems like Art could come up with a photo for that.) Anyway, so that +/- 5 or something like that would be necessary. But I'd love to see what people do with their 35mm focal point.

Most of what I've read puts the human eye at about a 50mm focal length equivalent.

And (some? all?) cameras without removable lenses don't have a "focal length ring" which can be turned to an exact setting, but use tiny motors to move the lens assembly internally, and don't have a way to set it to an exact figure.

Don't we have challenges all the time that exclude various people from entering due to certain criteria? Don't we run a billion challenges a week that one that might not allow some entries wouldn't be that much of an issue?

ETA: Hell, we are having a solar eclipse challenge which eliminates participation from a very large number of people! Run the 35mm. Then run other focal lengths as well.

We do. But I think when we eliminate a class of hardware (I'm guessing most P&S & phone cameras in this case) it should be a deliberate, conscious choice to exclude, not an "oversight" out of ignorance.

I'd love specific focal length challenges.

All that is is wording. Stop being pedantic.
