My first prime

I just ordered my first prime lens from B&H. The Canon EF-S (I know, I know) 24mm f/2.8 STM. 

 

I did this for a couple of reasons. First, was the fact that I've been getting a little more into street photography, and while I had been using my 18-55mm kit lens, I was finding it bulky at not so well suited for my needs. The 24mm prime, with an effective focal length of 38mm, would be ideal for me. I prefer it over a 50mm for street work. And I can use it in the field, in deserts and so forth. Then there was the cost of the lens itself. At $129 brand new, it seemed quite inexpensive. No, it is not for a mirrorless rig, but it didn't cost $2000 either. So until such time as I make the inevitable move into mirrorless, I think I got a good deal on a lens that I will be using plenty. Have any of you used the 24? What are your thoughts?

Yes, the hyperfocal distance is not quite infinity focus but close to it. I do not focus on a distant object. I focus on something beyond the hyperfocal distance, which is effectively infinity focus.

This is really easy to do with manual focusing 14mm lens. After a little experimenting on a tripod, I found the sweet spot fairly easily. As it turned out, the scale on the focus ring was spot on.

Not exactly, You use a depth of field calculator, find the dof limits for a particluar f number and set the focus for a point about 1/3 past the fist one.

Thanks guys, I've been reading up on using hyperfocal distance and have downloaded a calculator to my phone. Seems like a simple enough concept, if I can accuarately judge the distance LOL. I'll try it out this weekend.

That is one of the reasons that distance scales have survived.

Exactly.  Finding the hyperfocal distance focusing point is easier with a distance scale.

Not exactly is what I said.  But, it does work out to be nearly the same spot as infinity focus.

I browse that table every so often when I want to choose lenses to carry, and aperture settings to use.
