Digital Cameras Photo Reviews of Sigma 70mm F/2.8 EX DG Macro Lens for Pentax Digital SLR Cameras

Customer Review: Amazing hunk of glass and metal
Summary: 5 Stars

After researching macro lenses and considering my uses, I decided that I would get more use from a 70mm macro than other focal lengths such as 50 or 105. I see this lens as primarily a 70mm with macro capability for my purposes. And it is a great lens. Very sharp for all distances. Very nice color, contrast, etc. Solid construction, smooth focusing both manual and auto. This is a hunk of gear that is excellent in almost every way.

And HUNK it is. Heavy, big. Be prepared for this. Use a can of peas to get the idea. This isn't a complaint; on my Pentax K10D, it balances well and is a pleasure to hold. But it will start weighing you down after time around the neck.

My negative comments: The lens hood should be sized tighter so that it stays in place when reversed and you place it in a bag. The Sigma 'EX' crinkle finish is fine but not my favorite. The supplied case is bigger than it needs to be and yet doesn't provide much padding.

My most used lens. I didn't know that 70mm on an APS-C sensor (105mm equivalence for 35mm) would be such a nice focal length but it has become my new 'standard' lens.

Description of Sigma 70mm F/2.8 EX DG Macro Lens for Pentax Digital SLR Cameras

This medium telephoto macro lens is ideal for both digital SLR cameras and 35mm film SLR cameras. The 70mm focal length gives an equivalent field of view as our popular 105mm macro lens when used on digital SLR cameras with an APS-C size image sensor. The design of this lens makes it suitable for taking pictures in all situations from infinity to 1:1 macro, both with natural light conditions or flash. A Special Low Dispersion (SLD) lens and two high refractive index SLD lenses provide excellent correction for all types of aberrations and produce an exceptional level of optical performance. Sigma..s super multi-layer lens coating reduces flare and ghosting, and helps create a natural color balance. The floating focus system provides extremely high optical performance from infinity to 1:1 Macro. A "Focus Limiter Switch" in incorporated on the lens, improving the speed and accuracy of autofocus by limiting the focus range. A screw-in lens hood is included for convenient use of circular polarizing filters. * Pentax mount does not have an aperture ring, therefore depending on Camera model some functions may not work.
