I have several old 6 mp DSLR’s. That is adequate for most of my photography. I do wish they had higher ISO capabilities tho.
We are reaching the point where lenses may not be able to utilize all those megapixels.
Still, I wish I could afford one of the new models with their super sensitive sensors.
For cell phones, I doubt the lenses can utilize that much resolving power plus they take up a lot of memory.
I use a GH4 and love it.
For Christmas for me, I got a macro lens for it. I have taken one picture with it.
I was sick with a bug lately on top of the dentist doing some work.
I’ll turn it on some day.
