Any comments...yes.. This focal length means you'll be very close to your subject/target physically - too close for my liking but maybe it'll work for you..

Hope so - if not I'll probably change for Tamron Sp90 - Unfortunately no decent shops to try either of these lens near me. I'll use for portrait's & in general as a sharp lens anyway.

If you want the lens to take macro photos in the 1:1 magnification range don't get the Nikon 40mm. The working distance of this lens at 1:1 is tiny, really tiny. You'll be not only right on top of your subject, but you'll be heavily shadowing it with the camera and lens, plus you'll have limited space to fit lighting setups in to correct the shadowing.

For general shooting and close up work, yes it can work well, but for 1:1 I would never use a lens shorter than around 60mm. The Tamron 90mm would be an ideal lens to start with, even though it extends you'll still have more room to work with and to light your subject.

Cheers for the advice, Do you know 100% if AF works on the D3100 - I'm pretty sure it does - I can always send it back if I absolutely have to, as I have on order now (v.exited!!) It was the extension I was worried about to tell you the truth but a few people have pointed towards The SP90, whilst away from 40mm Nikon micro - I'm sure their both ultra sharp - but I do want a good crack at getting properly close up. Just reading 'close-up photography' - Bryan Peterson, pretty good, he says you get the equivalent of one and a half times mag on a digital.

Magnification never changes no matter what format you use. Crop sensor or fullframe you still get the same 1:1 magnification ratio.

That is - the size of the image reflected on the sensor by the lens is the same size as it is in real life.

However what changes is the size of the frame; a 35mm camera (film or "fullframe digital") has a larger frame size, so it captures more of the scene around the edges as compared to a crop sensor digital camera which sees only the middle parts.

The magnification is the same, however if you were to print out (or display online) photos taken by both the crop sensor would "appear" to have a more magnified image.

In ref to Tamron SP90, any particular filter I should be looking for for this lens, either for macro or general/portrait ? I like to get one pretty early on as protection as much as anything else. Also is it worth trying with extension tubes?

I swear by B+W MRC filters and have only bought these for several years now. Not cheap, but you want something with as good quality glass and coatings as your lens!

I can't seem to find what size I'd need, I think a 55m ??

Tamron website says 55mm filter thread for the "SP AF 90mm F/2.8 Di MACRO 1:1"

I'm going to try a B+W MRC circular polarizing filter - 35quid didn't seem to bad - your right, it would be a very stupid thing to put a cheapo filter on such a crafted lens, not to mention a waste of money buying it in the first place!
