A Stunning Shape From Sigma

A Stunning Shape From Sigma

I frequently pass by the Sigma racks in the storeroom but foolishly never stop to pluck something from the shelves. My fault, because I am missing some of the most intriguing lenses in the place. The shooters who use Canon or Nikon camera bodies get a better chance than I to test things out. And someone with a Nikon Full-frame DSLR will be the one to take an interest in today’s lens.

The dear old 105mm lens has been the mainstay of the portraitist for a long time – when mounted on a 24 x 36 camera it is perfect for head and shoulders and upper torso shots – such a good combination of focal length and depth of field that these lenses are frequently ground with a wide maximum aperture. f:2.8 is common and then it’ll run up to f:1.4 in the premium ones.

f:1.4 for this length is a sizeable chunk of melted sand and demands the best design for the resolution and freedom from distortion, It looks as though it also demands the best possible barrel mounting – this is what Sigma has supplied in their 105mm f:1.7 Dg HSM lens.

But you pay in size – thats a 20¢ piece, not a 5¢. That’s one serious lens hood and metal barrel.. and look at the mounting foot…

Okay, you can remove it, but the fact that it has an integral Arca/Swiss profile suggests that this is a lens that needs some rugged support. I found myself longing for a Nikon DSLR to try it outside, because I cannot remember seeing a lens a clean and clear as this one  straight out of a box. Of course it is entirely compatible with the metering and aperture controls of this and the other mounts it serves.

I must pull more Sigma off the shelves and see what they are making these days. If you’ve the body for it, you can take one home.

    Impressive chunk of glass!
    Any chance of taking a look at their super telephotos or long (600mm) zoom lenses? Worth a trip to Jandakot I’d say!

      What a temptation. Now how do I persuade the management to let me out of the front door with a very long lens and a very expensive body…hmmmmm
