Where's the better quality when cropping -- APS-C or FF cropping in post
May 3, 2017 18:37:52 #
I will be shooting the solar eclipse in August with my Sony A7R2 and a Tamron rental 150-600mm . In full frame my camera produces a 42MP file. In APS-C mode, the file size is 18MP. Does it make a difference in final image quality if I shoot in APS-C mode or crop in post? Thanks for any advice

There are some inherent issues with crop sensors. They've gotten better. I'd say go with the larger format, get more data with which to work, and better cropping ability in the end. Bigger is better.

NO ......either way you still have the same pixel density. If making larger size images for viewing or prints, do not be afraid to use pixel enlargement.

It doesn't matter which way you crop from an image quality point of view. Truth is you are going to crop anyway, unless you need parts of the image that would be cut off by cropping in the body, it won't make a difference.

I was told lately that you need a special filter to shoot eclipses. You might want to check that out before August. I have never had the opportunity.

I think you misunderstood the question - she is asking about full frame or crop mode on the same body - not asking about using a crop sensor camera.

If you shoot both with the zoom at the same focal length, the sun on the APS-C setting will fill more of the frame. If you enlarge and crop the FF shot so the sun is the same size on both, the image quality should be the same. If you zoom in with the lens so that the image of the sun is the same in both shots, you are setting the quality of the lens and increased potential for camera shake against the resolving power of the A7Rii. My money would be on the resolving power of the A7Rii.

The larger file is always better. You had better understand the problems shooting the sun. You MUST use a quality sun filter. If you don't you are likely to destroy your lens, camera, and your eyesight. Do not let someone that does not know what they are talking about tell you a cheap way to do it.

It's a great skill which many UHH's do not have.

With my camera I don't have the option to choose between FF or crop. There are other things, where I do have options, for example: number of focus points, shutter release button or back button focus, AF or MF, and a number of others. To me all of them were a challenge, and I've tried them all to find for myself what works best. It was fun doing that, and taught me a lot about my camera.
You still have about three months to the eclipse, so I'd suggest you get your camera out and start playing.
No, unfortunately no "practice eclipse" before then, but maybe you could find a bright light (partially) hidden by a tree branch? Or even set up a Coleman gas lamp and set something in front of it to cover (most) of it? You may surprise yourself and learn some things about your camera you didn't yet know :-)

They are the same. In other words, the same lens gives the same image size (assuming image not bigger than the CF view) and the pixel density as noted above is the same because it's the same sensor.
However, if the virtual CF impinges on the image then you should use FF.
Bottom line: same lens, same sensor, same physical size of image on sensor, same pixel density.
Area of CF (real or virtual) = 366.60 mm-sq Area of FF = 855.62 mm-sq
42 MP / 855.62 x 366.6 = 18 MP , approximately.
