One of my interests over the last two years has been cemetery photography. Usually, I use a zoom with a wide range for flexibility. Since it is rather slow, I usually wait for sunny days to do my shooting.
However, yesterday it was nice and gray outside, so the light was gorgeous. It was somewhat dim, though, so on a whim I pulled out my 135 f/2.0 (which I usually use for portraits and indoor sports) and headed out to see what sort of results I could get with it.
Wow, what a lens... Everytime I use it I think, "Uh, why don't I use this all the time?"
Here is a comparative example of two shots of the same subject, one with the 24-200 Tokina at 24mm in bright sun and the other with a 135 f/2.0 under even, gray light.
As you can see, there is no comparison. Of course, I had to get 100 feet away and shoot through some trees to get the shot with the 135, but still..... what a difference. There is a reason they still make primes, BTW, and this is and example of it.
