I was curious to see how these two lenses compared, so I mounted both on my A7, put the camera on my most rigid tripod, with OSS disabled, a 2-sec. timer on the shutter, ISO 100, daylight white balance, f/5.6 for the 70mm and f/6.3 for the 200mm (both being the widest aperture that the SEL24240 could manage at those focal lengths). Unfortunately the Oregon weather didn't cooperate, so the light changed as clouds came and went. But I hope it didn't affect the results of the test. On all of these, the SEL24240 is on the left and the SEL70200 is on the right. Here's what I got: The scene at 70mm. 100% crop of the center of the frame: And the right side of the frame: At 200mm, the scene: Again, a 100% crop of the center of the frame: And the right side of the frame: And the relative size of the lenses themselves: For those of you who are curious to see more, I've posted some sample images from the SEL24240 in this thread.
