Summary for Sigma 70mm F/2.8 EX DG Macro Lens ...- Macro With Exceptions
Notes on Sigma 70mm F/2.8 EX DG Macro Lens ...- I must qualify my review by stating that shoot macro lenses in manual. I shoot flowers. I never goto 1:1. I'm using it on a Nikon D80 and a Nikon D300.
The Sigma 70 is a nice lense. It's well built. It handles well. Color is acurate and contrast is good. My only issue with this lens is it is not sharp at F18 to F22 which is common amoung many macros. If I stay at F16 with moderate magnification then it stays sharp. As a matter of fact its shrpness at normal magnification is identical to the Sigma 50mm macro and Tamron 90mm macro. When I want higher magnification I goto a longer lens which is why I have 50mm, 70mm, 90mm and 105mm macro.
If you want to do macro work at less than 1:1 and you stay away from F18 and F22 then this lens will work fine. I gotten some great shots with it.

Notes on Sigma 70mm F/2.8 EX DG Macro Lens ...- Optically the Sigma 70mm macro was a decent lens for macro, but not a good all purpose lens at all. The build quality really turned me off. I tried the Tamron 90 macro, better build quality, better optices for both macro and general use. Decided on the Nikon 105 micro with vibration reduction. About 300 bucks more but a world apart in build quality and optics. A truly professional lens. In fairness though, I have to say that for the money, the Tamron was OK.

Notes on Sigma 70mm F/2.8 EX DG Macro Lens ...- After a lot of research, reading reviews and looking at sample photos from different macro lenses I ended up buying this one. It's my first macro lense, so I I don't have personal experience from other comparable lenses. But I do really love this lense.
It is quick with focusing and has smooth manual focus.
The picture quality is amazing. I especially like the soft blur of out of focus objects the lense gives.
One reason why I chose this lense was that it has coating layers on the glasses that limit glare in photos where strong light is in the frame.
The build seems really solid, and is a bit heavier than other lenses of the same lenght. It balances well with my canon xti.
Overall I'm very satisfied and I will take loads of beautiful pictures with this lense.

Notes on Sigma 70mm F/2.8 EX DG Macro Lens ...- 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.
