My current phone is a Galaxy S5: F/2.2 aperture, 1/2.6 sensor, 16 megapixels. With that I can take detailed closeups of bugs and such. I typically shoot a photo as close to the subject as focus allows, then crop the result to enlarge the subject. I don't even use the zoom feature because it just blurs everything.
I'm forced to upgrade and am having difficulty determining which phones have cameras that might best suit my needs, for instance:
- Galaxy S7: F/1.7 aperture, 1/2.5 sensor, and 12 megapixels.
- Moto Z Force: F/1.8 aperture, 1/2.4 sensor, and 21 megapixels.
- Asus Zenfone 4: F/1.7 aperture, 1/2.55 sensor, and 12 megapixels.
How do I analyze such data to determine how to best suit my needs?
Would, say, an F/1.7 aperture enable me to get physically closer to the subject than a F/2.2 aperture, thus negating the need for increased megapixels to allow for cropping? Or is there even a correlation there?
How does pixel size even factor in? Or focal length?
