Yeah I love my A7. I don’t generally enjoy shooting digital, but I really like the A7 because I can put my Leica lenses on it, or really whatever weird old funky lenses I find at swap-meets; and the focus assist where it outlines whats in focus in a color makes shooting manual lenses on a digital camera super easy.
I don’t know digital well enough to point you to other digital cameras I recommend, but dpreview.com is the site I use to look at all the time when I was researching digital cameras.
