In rough order, my preference is:
- Tokina 28-70mm f/2.6~2.8 (Either the PRO or PRO-II versions)
- Tamron 28-75mm model A09 (Early models have aperture rings, later ones do not)
- Another 35-70mm f/2.8D
Thanks for this advice, benveniste. I found a Tokina 28-70 2.6-2.8 that looks basically new, and it does not disappoint. It is amazing that you can buy a pro quality lens at this price if you are willing to forego a focus motor in the lens and VR.
For those who stumble on this thread from Google, here are my thoughts on the Tokina:
1) You zoom by turning a ring, instead of the push-pull of the Nikon 35-70mm 2.8. I don't really mind the push-pull type lens, but I am more familiar with the ring, so I appreciate this.
2) I LOVE that the zoom and focus move in the same direction as real Nikon lenses. I am aware that most other manufacturers do it differently, but I use only one 35mm system - Nikon, so this keeps it very easy for me. I have a Tamron I almost never use because it is awkward and slow for me to do so.
3) I did not realize it, but although the front element turns with the focus, it is set back in the barrel. What that means i that screw-on filters do not turn when you focus, because the barrel doesn't turn. You can set your polarizer and forget it. This is great.
4) The image is great. I mean really, really great. My Nikon had the haze problem (though not all of those Nikons had that problem), but this Tokina doesn't. The photos really "pop".
5) It focuses down to 2 feet. I don't know what the official close range is supposed to be, and I don't know if that is good for this type of lens, but it seems close to me, especially at the 70mm end.
6) It has an aperture collar, so I can pop this on any of my film Nikons and use it. I can't do that with newer lenses, even if they do cost several time more.
7) This lens has some kind of "clutch" to change from auto to manual focus. It takes some getting used to, but is no more difficult than having to flip a tiny switch on the side of the lens with your fingernail. The fancy new lenses that automatically switch between AF and MF are the ideal, but this lens is not that.
I have been using it with my D700 to familiarize myself with it, and it focuses as well as any first party lens of similar vintage I've ever used. If you are thinking of getting one of these, I say go for it. I don't shoot pictures of white walls and diagrams, but the photos this lens is putting out for me are in sharp focus and contrasty.
