Hey! So, recently, I upgraded my lens. The 18-55mm standard kit has done well for many years now. I'm still keeping it. But I want a faster lens in my arsenal. So, I got the Canon 50mm f/1.8. I'm pleased with the results. I've been taking indoor low light photos lately and the kit lens just don't cut it. The shutter speeds are too slow (especially hand held exposures).
I decided to do a little test. The light source for these photos was a small hoodrange light above an oven/stove. (I color corrected the pics since a dull yellow cast was present).
Aperture Priority @ f/1.8
Shutter Speed: 1/250
Aperture Priority @ f/8
Shutter Speed: 1/30
The shallow depth of field is quite obvious in the first photo. Even when looking at the pizza itself, certain parts of it are noticeably out of focus. The background where the baking sheet ends is blurred out at well.
The second photo was taken at a larger f stop giving a greater depth of field. The pizza is completely in focus and you can make out more of the baking sheet and crumbs in the rear. The shutter speeds I got were terrific. If I was using my 18-55mm kit lens, I would probably get a shutter speed reading of 0"3 or 1.5 seconds..not good for hand held photos.
So, yea..I'll defintely be looking for some good photo ops in the weeks to come. Good lens! (and good pizza too). :)
