Sony A7 vs A7R: Part 2, Flare

Sony A7 vs A7R: Part 2, Flare

In the hot seat: Is there really a difference with flare between the new Sony A7 and A7R?

Lets find out. First, I noticed flare most with wide angle lenses pointing into a bright light source, like the sun. So lets setup the tripod, set the camera on manual, and try some wide angle shots with the CV 12mm f/5.6 and Canon FDn 20mm f/2.8, the first is at f/11 and the latter at f/8.

I positioned the sun in the frame until I noticed large flare spots form, and then took a shot in manual mode with each camera in the same spot. The angle could be a tiny bit different since I had to swap tripod plates.

What do I see in the following photos? The A7R handles sensor flare much better than the A7. I don’t know that the A7 is problematic, but it definitely doesn’t like the sun directly in the frame. Would it prevent me from buying it for my uses, shooting events/weddings, general shooting, etc? No. Which would you get if you wanted to shoot mostly landscapes and night time cityscapes? I would get the A7R.

If you look at the first set of images from the 20mm, notice the rainbow pattern around the flare spot. I couldn’t get the lens to produce the little orbs today, but will try again later, with maybe the sun closer to the center, regardless, the A7R has much cleaner looking flare spots.

For the second set of images, the flare to the upper left is just the lens, not the sensor. Again, the A7R is maybe a little cleaner.

    A7 have sensor internal reflection problem

    The “flare” problem (in fact due to reflections off the A7’s sensor cover glas or AA filter) has benn documented by many others and is, just one example, discussed e.g. here: http://www.dpreview.com/forums/thread/3613281

    It appears to occur with most lenses (not limited to wide-angle), even native FE lenses (2.8 35 and 1.8 50) but NOT on the A7.
