This lens is just brilliant. The clarity of the produced images is superb.
It can sometimes be difficult when using it hand-held, but once you figure out the settings, you will be producing excellent results.
I found that setting my 450D to fully automatic often produced images with very shallow depth of field, so now I use Ap priorty and set the aperture to around F8 ro F10.
The macro capabilities are far better than I had hoped, and this lens should be a part of any photographers kit.

The delivery took a long time and when i emailed british bargains about it, i didnt get a prompt reply and when i did get a reply it was when I had already received the item. I sent it back and got a refund in good time.

i am just an amateur, but i am highly delighted with the sigma. first of all i checked out the nikon 105mm as i believe you get what you pay for, but the extra cost just for vr didnt add up, also in macro vr doesnt help that much. so use a tripod or take more shots and pick the best one. anyway as for the lens its briliant with crystal clear images and deffinately worth the money

I bought this macro lens as I wanted to do some basic macro photography using a full-size sensor.. Firstly I can definitely recommend that 100mm focal length is ideal for starting at macro - 50mm is just too wide (probably more use for portraits) and 150mm is just too expensive.
This Sigma lens is solidly built and certainly doesn't feel plastic at all - it's part of the EX range which are the top tier of Sigma lenses (easy to spot by having a gold ring at the end of the lens). Focussing is sharp and as a keen amateur I certainly can't see any shortcomings in this lens in terms of quality (f2.8 is certainly wide enough for me as even at that aperture I can throw the sharpness on macro shots very easily - I actually found I was using f4 most the time as the sharpness was falling off too quickly so focus has to be spot on)
There are a few things I don't really like about this lens though. The auto-focus is quite slow (especially when compared to the USM Canon equivalent, albeit quite a bit more expensive), and the collar which is used to select auto or manual focus is quite clumsy and just doesn't feel right. That said for most pure macro work you're best off using the manual mode and once in that setting the control is pretty good.
My other complaint is that if you put a UV filter on you can't put the cap on - this is because the cap fits the inside of the front of the lens in a slightly different way to most lenses... easily rectified with either not using the UV filter (which is fine since the front of the glass is set a long way back from the front of the lens so is difficult to damage) or buying a suitable cap (prob £10).
