In the first jeep test, what some people are seeing as contrast differences between image 2 and 3 looks more like a slight difference in exposure to me. Note the skid plate under the front bumper and tires. It's noticably less dark in image 3 than image 2. It's almost like there's more shadow detail which is why I'm thinking an exposure difference.

In fact, many elements in the third jeep photo are lighter than the second photo. Look at the leaves on the branch over the garage door, the shrub in the background on the right of the jeep. Even the windshield looks brighter on the third jeep which is all highlights.

If the difference between 2 and 3 was contrast the highlights would be brighter and the shadows darker. But I'm seeing everything in image 2 is a bit less exposed leading to the appearance of more contrast and saturation.

Is it possible one lens is alowing slightly more light, resulting in a slight increase in exposure?


This may have been my fault. I used manual exposure settings and in the first test all three were slightly different apertures--F2, F2.4, and F2.5. I did change shutter speeds, but this may have resulted in differing exposures given no additional post processing (no exposure changes in post). Sorry about that! Second test with both at F5.6, this should not be an issue.
