NEX F3 - Does the lack of touchscreen makes things difficult?

Hello!

I am thinking of buying the F3....

To those who have it...or compared it to the 5/6 series - is not having a touchscreen an issue when using this camera?  If you have this one...are you frustrated by scrolling/clicking around before you take the shot?

When comparing the specs...they are all kinda the same camera.  I am guessing the sensor is the same between them.  I like that this has the flash...easy to hand off to wife in auto mode and take some photos.  Things like WIFI or extra FPS are not a deal breaker for me.  I see a lot of talk on this board with members that have 5n 6 7....not much from the f3 crowd.

What would make you skip over this one and get the 5 or the 6?  My plan is buy something and swap out the lens with adapters or go the Sigma route (30mm).  I wish this (f3) had a body only price...

Thanks!
