zackiedawg you are awesome and just the type of person I was looking to find. I have tons of point and shoots and an old SLR (still uses FILM

)
Thanks - and no problem. I actually have several film cameras still around the house - including my Pentax ME-Super and Canon EOS-IX that I still used into the 21st century, and Konica and Chinon SLRs that I bought as packages with lenses so I could use the lenses on my NEX. I've had digital cameras from Sony, Minolta, Pentax, and Canon too - so I've gone all over the map!
Sony seems to have the best low light reviews, but it seems the Olympus Pens have the fastest auto focus.
That's about right - but remember too, those are straight tests - the Oly isn't THAT much faster than the NEX in normal use for most folks, and the NEX isn't THAT much better in low light in normal use for most folks. It's generally those more rare shooters who really need to push the limit, either in action focus speed or extreme low light handheld.
So you think the Nex 5N would be a good choice? Does it have a manual focus setting?
Indeed - most of these cameras, including the NEX5N, have manual focus ability. They are switchable between auto or manual focus, can work with all manual focus lenses, or can even use a hybrid mode (Sony calls theirs DMF, or Direct Manual Focus), whereby you can autofocus a scene, then grab the focus ring and fine-tune the focus manually before shooting.
The NEX-5N certainly looks like one of the nicer ones out there, with a ton of features, a nice tilting LCD, touch screen, high ISO ability, an optional electronic viewfinder option you could get in the future if you decide you want one, and the very cool multistacking ISO, HDR, and sweep panorama modes which work very effectively. Just make sure you like the way it feels in your hands. Don't worry too much about any of the controls with the NEX or Micro 4:3 cameras - they may not seem well laid out, or lacking too many buttons, but all of these are highly customizable, allowing you to assign all your most-used controls to the buttons of your choice.
As I said my terminology is, well non-existant, but one thing I like about the old SLR is the ability to turn the lens and "choose" my focus point.
While most folks stick with autufocus on digital cameras, you actually might occasionally enjoy playing with manual focus or even a manual lens or two - because the manual lenses on these cameras really delivers that feel of a classic SLR - there's something enjoyable about a nicely damped manual focus lens.
I read on a few other cameras that you can tap the screen to pick the focus point.
As far as I know - most of the Micro 4:3 cameras with touch screen can do this, and the NEX-5N can do this. There is a slight difference in how they function - the micro 4:3 cameras can allow you to touch to both focus and fire the shot, while the NEX-5N allows you to pick the focus, but you still press the shutter button to shoot. Either way, it's a neat feature.
I would love to be able to use those old lenses on a digital camera but they are just so darn heavy to lug around the parks all day.
They're definitely heavier than the native lenses, but depending on the lens, some can be pretty nifty. The short primes, like 50mm F1.7s and 35 & 40mms with an adapter can actually be as small as the kit lens, and not much heavier, plus just deliver a satisfying experience turning an aperture ring and focus ring to shoot 'old school' style. Still, though I have over a dozen manual lenses for my NEX, I still do the bulk of the shooting with the 18-55mm kit lens just autofocusing, as it's just the most convenient.
Maybe I have to go back to
Best buy and play some more (I prefer Best buy to the camera stores since mine has a lot of high end SLR stuff and they dont hover over you like they do in the speciality camera stores)
That's a very good idea. You may find you really like the style, the grip, the feel, or some key feature of one particular model over another, and you really aren't going to make a bad decision no matter which you go with. Try to tune out any reps that do try to talk you up, as they may be biased towards a particular model and might sway you away from your instinctual choice.
