Prime primer

I teach “Lenses” this afternoon (Saturday) at Vistek in Mississauga before leaving for the Sunday workshop in Timmins, Ont.

So while I am on it, let me see if I can give you some input as to why you might want a prime lens. I have explained before of course (consistency, sharpness, size, wider aperture..) but a picture, well, a picture tells 1,000 words.

Here’s my kitchen island:

Now let’s look at 1:1 pixels. Straight out of camera, and pixel for pixel; 1/80-th second at 800 ISO.

First, the 24-70 f/2.8 zoom at f/2.8, set to 50mm:

And the 50mm f/1.2 lens, also set to f/2.8:

Both are good. But when you look closely, really closely, especially at the cloth material, you see that the 50 is much sharper.

No surprise, it is stopped down while the 24-70 is wide open. But that is the point, isn’t it? In real life use the prime often gives me sharper pictures.

This fact, and a million others, in the “Lenses” course at Vistek Mississauga (after “Flash”, also a great course, if I say so). See you there perhaps!
