Great Lens at a great price, January 17, 2008 Amazon Verified Purchase This review is from: Sigma 70mm F/2.8 EX DG Macro Lens for Nikon Digital SLR Cameras (Electronics) I've never been a big fan of Sigma Zoom lenses, but their prime lenses are top notch. I've been using the Sigma 105mm and 50mm macro primes on my Canon full frame bodies so I decided to pick this lens up for my Nikon D300 to give me a 105mm equiv lens for that system.
In a nutshell, this lens is fantastic. It is very sharp corner-to-corner on my Nikon D300. It is sharp wide open at f/2.8 and stays sharp up until about f/11, where it starts to soften just a bit. Lens construction is very sturdy and typical of the top-end sigma primes. Autofocus speed is adequate but not as fast as the best Nikon lenses. It also makes a little more noise when focusing. Manual focusing is excellent with a very smooth and precise feel. I really like this lens and it may be one of the sharpest prime lenses on the market. I highly recommend it.

I bought this lens for macro and with the 1:1 ratio, it gives great pictures. With its f/2.8 at 70mm (which is equivalent to a 105mm in digital) it does work brilliantly for portraits (I thought it could be slightly slow but it is not at all!).
At this price, it is a great lens to have in your bag.

It's good, but it's *not* a constant f2.8 lens (edit: most Macro aren't!), June 7, 2009 Amazon Verified Purchase This review is from: Sigma 70mm F/2.8 EX DG Macro Lens for Nikon Digital SLR Cameras (Electronics) Bought this to pair with my Nikon D90. It's a sharp lens that's very pleasant to use. As the other reviewer said, it's a 'nice' length on an APS-C sized sensor, ~105mm. Sharpness is on par with the venerable Nikkor 50mm f1.8, IMHO. So that's great. Not unexpected though, as this is supposedly Sigma's sharpest prime lens and it's a Macro lens, which by definition has to be tack sharp. Build quality seems very good too. All in all, it's a nice lens at a good price.
Focus is slow compared to AF-S lenses, but only because there's such a huge focal range. This lens does seem hunt a lot on my D90, even in bright light. It'll often have to run the focus across the entire range to get a lock, and that's a pain. However, flipping the focus limiter switch solves it and makes it focus just as fast as my other non AF-S lenses. So that's ok. And for macro shots I'd usually be focusing manually anyway, so it's not a big deal. But it's just not quite as quick as my AF-S... Read more
