I have a friend who wants to purchase a macro lens. I don't
think he's new to macro photography, but /is/ new to macro.

What kind of pictures does he want to take? DX-format digital or
full-frame?

One problem with short macro lenses (such as 60 or 70mm) is that one may
have to get too close to the subject to make it easy to light. That's why
Nikon makes 105mm and 200mm macro lenses.

The 105mm is interesting because it includes vibration reduction, which
means it will also be useful for handheld portraits, etc. It's an AF-S
lens, which means it won't focus on older bodies (such as the N8008).

The 200mm offers the longest working distance, but has no VR and focuses
mechanically (which is relevant only if you're using a D40). It's also more
expensive than the 105mm

Thanks Andrew.

I think he has another couple of lenses - I think "kit" lenses.
I'll ask. But I think he'll only want this for macro. Not sure
what camera either - I should have asked that too.

The Nikkor 105mm is double the cost of Sigma 105! Acknowledge it
has stabilising, but that's a lot more.

Thanks for you input.
