My wife is a relatively newcomer to photography. 2 years ago, I bought her a refurbished Fuji 6500fd prosumer to start her off. That camera has a live view screen and an EVF (albeit a lower resolution than today's offering). From the start, she prefers to use live view to compose her picture. I kept telling her that she should compose using the EVF but she hated it. I thought it is the low resolution EVF that put her off but she said that's not it.
Then when i upgrade to the K-7, I handed her my k100D and then she has no choice but to compose using the OVF. I can tell she does not like the camera very much.
So later i have some cash and i bought her the K-x. She loves it, esp considering that is has a workable live view screen. She still uses live view to compose her picture and rarely uses the OVF. Does she take worse pictures than me? I think not. Friends kept saying she has better photographic eye than me.
I guess what i am trying to say is that, as enthusiast photographer, we may prefer a certain way to take our picture, either we were brought up in that fashion, or we are led to do it in that way. It is not wrong but it is not necessarily the right way and the only way.
I would have preferred the K-01 comes with an OVF because that's how i would like to use it but it does not. I take a lesson from my wife in learning that, a picture taken from a camera is a picture how you want to see it. Whether you are viewing it thru an OVF/EVF or a live view screen has little influence how good your photo is. Of course I understand the limitation of live view when it comes to using at night but for 95% of the time, live view is just fine.
So will we be buying the k-01 even though it has no OVF/EVF? You bet
