I figured I would try something a little different today so I took the three bodies and three lenses and shot three subjects. I first shot some holly berries which hang low on one of the bushes in my yard with the 85mm f/1.4 at f/1.4 and f/4. Finally I zoomed in on a treetop at 300mm on the A99 and A900 and at 200mm on the A77 with the 70-300 G SSM lens at f/5.6 and f/8. Definitely not a scientific test as I guessed on the distance differences and I know the depth of field will be wider on the A77. All three bodies were set to 5000k for white balance, wide focus areas, wide metering, ISO 200 with SteadyShot on.
Since the tests aren’t scientific, and I definitely saw a difference in light as the sun and shadows moved, I figured I would put the shots in random order and if anyone wants to guess which one is which, feel free to comment.
Here is the first set of 85mm f/1.4 shots. Can you tell which one is which?
As you can tell, the light was slightly different as was my position. This is where I learned to shoot with the A99/A900 first and the A77 last as I shot A900-A77-A99.
I didn’t pick a determined focus point, and at f/1.4 I’m shooting with a very narrow depth of field, but the colors and other factors are still relevant. Here is a closer look. They may be in a different order.
All three render the red berries slightly different. It could be the light, it could be softness in the lens wide open. Who knows. A more fair comparison is the f/4 shots.
Here is the Zoom shot. The A99/A900 shots are at 300mm and the A77 shot is at 200mm. These were shot at f/8. I didn’t have a predetermined focus point. The point of this exercise is color interpretation and noise.
One of the bodies metered the shot significantly brighter than the other two. Here are some zoomed details.
And three others
And finally for kicks, the f/5.6 shots:
So what are the guesses? I’ll post answers as well as metering information on the next test-specific post.
