Hi Nathan!I would also like to welcome you to Atlanta!This is a great place to live except for traffic sometimes,LOL!As for photographic opportunities there should be plenty,just go up and down Little Five Points area where you live,the night life can get colorful and festive at times.Honestly there is much to be offered like many good size cities.
As for walk in Pentax stores ,well you will be disappointed as NO big store is going to carry Pentax.I think this is a trend across the country not just here.You may find an occasional store with something(Frys had a K7 recently but not even a battery
) so I shop off internet and here for my gear so no problem any way.KEH,yes the store is here but not walk in but good deals to be had sometimes. Wing's was mentioned and Mike the owner(really an older family bizz) is a friendly guy but a small shop,mostly used gear,well picked over but sometimes a gem may be found.For other gear other than brand specific like Pentax is the store known as Showcase,a well established photostore.Used by a lot of pros here and has a large staff and inventory lacking Pentax of course.But if you are needing a tripod or a bag or the likes you want right now this could be the place,worth the visit anyway just to check out.Also they have a Photography school there also(different nearby building)with decent instructors IMO at a reasonable price and is also a good way to meet a few camera type people and brush up on some skills if needed.There are also several small camera clubs and meet-up groups also that are active and can give you things to do here.I know of the one in Decatur that is very active and near you.So unless you get board easily you should not have it bad here I promise,it is what you make it!
So what brought ya to Hot 'lanta?.....
