Switching to full-frame - A LOT of questions!
I am wanting to transition to a full-frame camera. Right now I am shooting with two Nikon D7100 cameras. I am looking to buy two Nikon D750 cameras (I think?). These are my current lenses:
Nikon AF-S VR Zoom-Nikkor 70-200mm f/2.8G IF-ED
Nikon AF-S DX Zoom-Nikkor 17-55mm f/2.8G IF-ED
Nikon AF-S Nikkor 85mm f/1.8G
SIGMA 18-35mm F1.8 DC HSM | Art
SIGMA 8-16mm F4.5-5.6 DC HSM
Tokina AT-X Pro SD 12-24mm F4 (IF) DX
From what I understand, only the 85mm will work with full frame, so the rest have to be replaced (I haven't used the 70-200mm in years, so I'm not worried about getting a FX equivalent, I just want to sell it). I mostly shoot outdoor portraits (large families to individuals) and realty (for builders, realtors, rental companies, etc.). Currently, when shooting portraits I'll use my 85mm and 17-55mm (or 18-35mm) on my two bodies. So I need a lens to replace my zooms that would be good for covering large groups. I was thinking maybe I'd get a prime lens instead of a zoom, but I don't know which prime would be best (or if I should even go that route). Here's a link to a sampling of my beach portraits: PORTRAITS
When shooting houses I use my 12-24mm for the large majority of my shots (and almost always at 12mm), I use the 8-16mm for tight spaces, really small bathrooms, etc., and I shoot the exteriors with my 17-55mm. So I'll need new wide-angle lenses. Since I'll be able to capture more with full frame, will I still need to shoot with a wide-angle and a super wide angle? Here's a link to a typical realty job: REALTY
So to recap, I want to go full-frame and I need help choosing new lenses. Thank you for reading this! Also, I am tempted to contact Adorama and see what they can do for me as far as trading in my old stuff and getting new stuff. I want to sell/trade two Nikon D7100 cameras, two Nikon D300 cameras, and these lenses above. Is Adorama the best way to go, or am I better off selling the pieces myself? THANK YOU for any help, I know there are a lot of questions in there.
