I recently upgraded to a used D3 from a D70s and I need some new lenses on the wide-normal end. The upgrade to FX in the distant future was anticipated since I got into photography, but I came across a great deal on the D3 and impulsively bought it - spending almost all of my photography funds. The lenses I have are nothing spectacular, and some faster and sharper lenses have been on my wishlist for a while. I now have little cash to spare and desperately wanting some great FX glass, but on a tight budget. I am re-evaluating my current gear, and considered selling my D70s and 18-105 VR for some extra cash (an optimistic $300). This would give me about $500-$600 to work with for new lenses. My photography is all over the place. I have done a wide variety of projects, but my favorite has been portraiture/acting photography. (some samples in my photo.net portfolio) I always bring my camera with me when I travel or visit the zoo or aquarium, and I also go out with photographer friends and walk downtown or cool places we found on Google maps and snap away at architecture, landscapes, still life, portraiture, etc. It also doubles as location scouting for my planned shoots. It's mostly for fun, and seldom paid or trade for prints. Paid and TFP work has been product photography and portraiture. Anyways, here is the list of my current bodies and lenses: Bodies: Nikon D3 Nikon D70s (might sell for FX glass) Lenses: Nikkor AF-D 50mm f/1.8 Nikkor AF 70-210 f/4 Nikkor AF-S 18-105mm f/3.5-5.6 DX VR (might sell for FX glass) I would really like to cover the ~17-70+mm range with very sharp and fast f/2.8 zooms, but I can't afford that combination in Nikkor glass. If I give up on the fast aperture, the Nikkor AF-D 18-35mm f/3.5-4.5 and Nikkor AF-S 24-85mm f/3.5-4.5G Non-VR come to mind and fit my $600 budget. Neither of these lenses have a lens profile built into Lightroom (distortion correction). This might not be a big deal - I think I heard you can make your own profiles, or even download community made ones. If I stick with the very sharp and fast f/2.8 zooms requirement, it sounds like there might be some good offerings from third-party lens mfgs like Tamron, and in my price range. I have read a ton of reviews on Nikkor lenses and very familiar with the line up, but I am completely unfamiliar with third-party lenses. I've been reading a lot of reviews, forum postings, and looking at photos from different lenses on flicker, and still don't feel like I can make a good decision. The thought of adding a cheap Tamron or Sigma lens to my D3 makes me cringe a little, but if the optics are excellent, then I will go that route. After hours and hours or online research, it looks like the Tamron 17-35mm f/2.8-4 and the Tamron 28-75 f/2.8 are very good lenses that perform on par with Nikon equivalents and fit my tight $600 budget. And surprisingly, Lightroom has both these lens profiles built into Lightroom. Which of these lenses would you recommend? Is there something better that I overlooked? A quick note on zoom overlap: It's a good thing (for me). A 17-35 is a lens I would use when I want to go wide, and the zoom will allow me to choose from UWA to wide-normal. A lens from 24mm to 70+mm would be a lens I would use for the normal range, but could go fairly wide if needed without swapping lenses (35mm would not be wide enough in many cases, like in a small room and a wall keeps you from stepping back further).
