My point was that the change in effective aperture isn't an "option". Every 105mm macro lens will have the same light loss at close focusing distances.1/3 of a stop isn't as much of a difference- or as noticeable- as the 1.5 stops the 105mm VR loses
Recently had checked out these two lenses and their reviews are very impressive.
105mm cost only $480 and 150mm costs $700. By no way their price mark can catch up the Nikkor 105mm's $900. Reviews say the only differences are:
- Slightly noisier AF with Sigma (not important)
- Slightly slower AF with Sigma (not impoartant)
- No OS (as VR in Nikon) with sigma
In shooting macro VR seems less important because i will use tripod or shooting at high SS in daytime. But as i mention i am thinking of using macro lens to shoot portrait too. So i have a few questions here:
- Does Sigma 105 or 150mm macro AF on Nikon D40?
- Has anyone used one or the two Sigma macro lenses and how is the quality? I get told third party lenses have shorter life span but i wonder how short?
After studying your stated needs and responses, I suggest you upgrade to the D7K. This would give you the versatility you've mentioned in your original post. And, you might discover an entirely new dimension shooting with the bright 50-1.8 on the D7k.
The following is a thread I started on Nikongear earlier this year during my quest for an appropriate macro lens.
Choosing a Macro lens around 100mm
I call your attention to nfoto's comments on the Sigma. Bjørn is probably the most revered Nikon reviewer in the world. His praise of the CV-125 is the reason for the high demand and its consequential cost
My suggestion is sometimes we have to start building from the ground up. IMO, you need a better camera.

For Sigma lenses, you have to look for "HSM" in the title. That indicates an in-lens focus motor. Unfortunately, the 105mm and 150mm macro are not HSM lenses. Take a look at the Tamoron 90mm f2.8 macro. They just released a new version that will autofocus on the D40 and it's got a great reputation. Should give you the length you need, too.Does Sigma 105 or 150mm macro AF on Nikon D40?
Edit: Oops. I was mistaken on the 150mm. It is an HSM lens. I would still check out the Tamron, though.

That said, the Sigma was very good. It's just that my personal opinion is that the Nikon is better.
