Gear Wednesday – January 27th 2010 – L vs non-L glass and focal lengths
So tonight I wanted to try and make up a little for last week. Yup, I goofed and missed. So tonight I bring you L vs non-L glass. Also, I wanted to show you what some focal lengths look like from different lenses So here goes:
All images are pretty boring to look at, but are all identical. I would like to repeat this test with a much nicer shot, maybe outdoors next time.
The pictures are straight out of the camera, only resized for web. The camera settings are all:
ISO800 & shutter speed of 1/15th
First up is a Canon 24-70mm f/2.8 lens at 70mm vs a 70-200mm f/4.0 lens at 70mm
Notice how the longer lens is actually a little bit tighter than the wide angle.
Next up is a Canon 24-70mm f/2.8 lens at 35mm vs a Canon 22-55mm f/4-5.6 at 35mm


I first noticed that the second lens is a little bit brighter as well it seems to point up a little bit more. The brightness may be due to more of the lightbulb peering through.
Next up is a Canon 24-70mm f/2.8 lens at 50mm vs a Canon 50mm f/1.8 at 50mm(duh)

Again, notice how the Nifty 50 is a little bit brighter? Also, it seems to crop in just a little bit more than the 24-70.
Well…What’s the verdict? 1 lens vs 3? Let’s discuss.
