This is a very special lens.

Re: This is a very special lens.

Hmmm! How do they compare? They are both super sharp, they are both excellent macro lenses and also superior general use lenses. But since I got my Pentax 100mm WR lens, I hardly ever reach for the Sigma 70mm glass. Similarly when I had the Sigma 105mm Macro, I reached for it more often than the 70. I think it is just perspective and distance advantage. Even though the 70mm glass is sharp, maybe a smidgin sharper than the 100mm or 105mm lenses, the distance and perspective advantages made me reach for them. Also the Sigma 70mm lens is quite heavy compared to the 100mm WR and even the Sigma 105mm lens. The fact that the Sigma has a focus limiter didn't make any difference to my preference.

One situation where I would reach for the 70 is for shooting portraits. It is equivalent to 105mm in 35mm terms and so is ideal for head and shoulder shots. Having said that, it ruthlessly shows things like acne, wrinkles and other things people don't like to see in their portraits. For shooting children and young people though, it is magic.

Sorry, this is not very well said,but I think you see what I mean.

I notice from your signature that you have a Sigma 70mm macro.  I vaguely remember reading that the Sigma is also an excellent macro lens so as you have both I would be interested in your thoughts on how they compare.
