Architectural interiors can be as easy or as complicated, expensive, as you want to make them. It depends on the amount of time you want to put into the shoot and the time you're willing to spend in post.
First, there are two time in the day when the outside light balances with the interior, dawn and dusk. If you have the option to shoot at those times you can have an evenly balanced ratio of inside outside light. Shoot the reverse angles using the window light to light the room during the day, then be ready to get the in/out views at dusk.
Second, use fill light. I have used flashbulbs, blue photofloods, studio strobes or on camera flash. They all work, results depend on your effort.
Third, Take a tip from the cinematographers and filter the windows with either neutral density material or a combination of 85B and neutral density material. In the film days I used to use the 85B/ND material when we shot in 8x10 or 4x5 film. We used Tungsten balanced film because it handled the long exposures better.
Forth, Post production manipulation. HDR, or similar.
And always tripod your camera.
Good Light and Good Shooting!
You seem to be asking two different questions. Do you want a long lens for night-time sports or a fast wedding lens? For general sports with your half frame D500, I'd suggest a 180mm f2.8 and for a fast wedding lens a 35mm f1.4.
To Reinaldo: Sorry, but APS-C is hardly full frame. At 23.5 x 15.6 mm your A6000 sensor is slightly less then half frame when compared to the Standard of 24 x 36 mm for Full Frame. It is therefore a crop semsor camera.
I'd say take the 610 as I say full frame over half frame every time. Going to Europe I'd worry more about backup and try to carry a second body and second lens. Have a vreat trip!
First for interiors, tripod and level the camera. On my half frame, D90, I use a Tokina 11-16. On my FX body I use my 20mm.
The best lens is going to depend on what you're shooting, how you want to work and the camera you use. For copy/animation stand work, the 60mm MicroNikkor on a full frame or the 40mm MicroNikkor on a half frame body.
My Nikon Coolpix AW100 has GPS as does the current AW130. I usually have it in my jacket pocket as part of my edc. I'm too old to always carry a DSLR as I did in the film days.
Tripods under $100.00 are mostly junk. I use an old Quick Set Traveling Samson with a head where I cut down the camera platform to fit Hasselblads. I have used this for 8x10 Calumet and Deardorff csmeras down to my Nikons. In high winds i hsng sandbag weights from the lower center colum.
Sorry, but the combination of stress and, I hate to say, age did it to you.
If you don't need the full frame 36mp sensor for large prints, consider the D7200 for your needs. Half the price of D500, uses your lenses. Unles you have a bad case of GAS.
The Department of the Interior runs HABS. Check with them, they have very specific archival requirements. If you're not processing your own film you have no business shooting for HABS
Quit reading, except for science-fiction, and take pictures and make prints.
