Next Lens: 105mm f2.8 or 85mm f1.8 - One or both?

When shooting macro do you have to stop the lens way way down to have any DOF? If so then I can definitely see the usefulness of having VR when hand holding shots, especially if indoors on a subject that you may not be able to adequately illuminate.

RE: VR on a Macro - wouldn't know, neither of my macros (Nikkor 105 or 60) have VR. But I have not found it lacking. Most but not all of my macro are shot without tripod. Did some extreme close-up with magnifying filter(s) on my 105mm and then I needed my mini tabletop tripod - moving it a fraction of an inch made all of the difference in focus.

Well I'm seriously tempted to pull the trigger on the Tokina right now just based on the price to performance ratio, looks to be an amazing lens. The D750 can help me get by not having VR since it takes such great photo's at high ISO, I can pump up the shutter speed a bit to compensate....

Decisions decisions decisions!!!

Most people will close down the lens quite some when shooting macro. f/16-f/22 is not an uncommon aperture if you want enough DoF at 1:1. You're working with such a thin DOF that you're either required to stop down or shoot further from the subject and crop in.

And since aperture comes at the expense of shutter speed, especially if you shoot without flash, you often benefit of VR. At these magnitudes even the slightest movement has dramatic effects. Which is why tripods are often used although they're highly impractical for a lot of shots.

At 1:1 shooting an FX at f/8 will only have a DoF around 1mm if my math is correct. In macro everything is small.

10 Gauge -- I echo the general consensus so far. Since you included the macro requirement, I'd definitely get the 105 first. As for the Tokina vs Nikon vs Sigma 105s, I have no idea which is best, but all the info I've read about each leads me to believe they are probably so close in performance, you wouldn't notice much, if any performance differences. Another option is the Tamron 90mm f/2.8 Macro. Of these, I have the Sigma 105 f/2.8 Macro, but I only bought it a couple weeks ago, so I haven't had enough time with it yet to form a good opinion. So far so good. My only complaint about it to this point is it makes a funny noise when the OS is turned on.

105mm is a good focal length for portraits; you'll only need to get a little further from your subject than you would with the 85. The only real disadvantages to it vs the 85 that I know of are that it won't give you the extremely shallow DOF the 85 will and if you're taking group portraits in tight quarters (inside a small interior room, for example), it can sometimes be difficult to get enough subject distance to get everyone in the group in the frame. For most shots, most of the time, you likely won't need to go wider than f/2.8 even though it's nice to have f/1.4 or 1.8 capability for the rare shots you can benefit from the extra speed and razor thin DOF. 85mm is a better portrait length for indoors, but depending on where you're shooting 105mm will work great a high % of the time. It's only when you're constrained for space or you're shooting large group portraits when it might be too much FL.

If you're really serious about portraits, I would definitely consider getting a fast 85mm in the future, though.

I definitely think I'm going to go with the macro first, and may forgo the 85 all together and spend that money on a UWA instead. It's starting look like a Tokia 11-16 and a Tokina 100....

You do know the Tokina 11-16mm f/2.8 is a DX lens, right? You probably want the Tokina AT-X 16-28mm f/2.8 Pro FX?

I can't imagine going 16mm on an FX body but that's just me... I'm far more tempted by the Sigma 18-35mm F1.8 DC HSM but then I'm addicted to the Sigma Art lenses in general.

Nope I missed that COMPLETELY. Thanks for saving me a headache!

I love my 85mm on fx for the working distance it gives me with the models..105mm would be too far away for me..

It occurs to me that the Tamron 90mm Macro would be a great compromise between the 105 and 85 - 90 is so close to 85 as to make no dif - and it has macro. I know there are those who like it, a lot. I don't have one and since I already have a 105mm Nikkor no point. But maybe some 90mm Tammy owners would give their impressions. If I were in you boots I'l look closely at that one.

I looked in to the Tamron as well but it doesn't seem to score as high in the benchmarks for sharpness. The Tokina is still tempting me for price and performance.
