What customers say about "Key Specs"
Sigma 105mm f/2.8 EX DG OS HSM Macro Lens
  • The lens appears to be very well made from plastic with a metal mount.
  • F2.8 aperture – Good for exposure and background blur.
  • Focal length is long enough.
  • It is a good focal length for wildlife macros.
  • The focal length of 105mm is perfect for me.
Tamron AF 90mm f/2.8 Di SP AF/MF 1:1 Fixed Macro Lens
  • Very useful focal length for macro and candid/portrait shooting.
  • At its widest aperture the sharpness of this lens within its tiny depth of field is top-notch.
  • As well as an excellent macro lens with 1:1 magnification, on a 1.5x crop sensor you get an extremely useful candid focal length of 90mm.
  • To sum up, this lens is excellent if you need a macro lens with a longer focal length and you haven't got £500-600 to spend on the best ones.
  • The focal length at 90mm works well in both full-frame and APS-C formats.

What customers say about "Size & Weight"
Sigma 105mm f/2.8 EX DG OS HSM Macro Lens
  • The lens weight and size are very good with the camera feeling very balanced when the lens is mounted.
  • Great sharp pictures. Good weight.
  • It is weighted nicely, and feels sturdy.
  • Very heavy and not the quietest to autofocus.
  • A very heavy lens for the size.
Tamron AF 90mm f/2.8 Di SP AF/MF 1:1 Fixed Macro Lens
  • Lens is very light and easy to carry around without bogging you down.
  • 90mm is a really good size to have in your collection of lenses for sure.
  • It is heavy but with its size you do expect that and I feel it’s essential for what you’re getting.
  • Great product. I have used with and without tripod. Sturdy build and lightweight.
  • This is a heavy lens so it won't work out easy to take with you on any trip.

What customers say about "Imaging"
Sigma 105mm f/2.8 EX DG OS HSM Macro Lens
  • Manual focus is with the fantastically large focussing ring, this is very positive in movement.
  • The auto focus and image stabilisation were incredibly.
  • The image quality on distance shots was very good.
  • Auto focus works really well and also works well for portraits.
  • Well built lens and very sharp.
Tamron AF 90mm f/2.8 Di SP AF/MF 1:1 Fixed Macro Lens
  • Focus limit switch, very handy for non macro work to speed up the AF a bit.
  • Very smooth manual focus (as expected for a macro). It's a "full frame lens" so no problems if you get a FF body later on or shoot some 35mm film.
  • I've heard a lot about the grinding noise of the auto focus, I've had no probs with that. It may be a little loud when focusing but, when you have the radio you'll struggle to hear it.
  • Focus is not fast (it's a macro) focus limiter helps a bit here, screw drive versions tend to be faster.
  • Perhaps a little slow on focus but that is a really minor niggle. But It is annoying when you need to focus quickly.

What customers say about "Features"
Sigma 105mm f/2.8 EX DG OS HSM Macro Lens
  • The lens comes in a robust, padded case.
  • True macro, this achieves 1:1 magnification at the min focus distance.
  • 9 blade aperture makes smooth background blur.
  • Landscapes or portraits all works with that great piece of glass.
  • This is excellent value for money. It is well built and handles well.
Tamron AF 90mm f/2.8 Di SP AF/MF 1:1 Fixed Macro Lens
  • Superb optics even wide open, with a 9 blade aperture for smooth out of focus rendition. Stunningly sharp stopped down.
  • Good build (plastic but decent plastic) with a nice grip for focus and metal mount. This is just fine for the price.
  • The front element is well into the body of the lens which means you are not likely to use the hood much.
  • I love the macro features of this lens but primarily find myself using it for portraiture, especially pet portraits. It's fast enough to get great actions shots from a distance.
  • Due to the recessed lens elements you are closer to the subject for 1:1 macro than you might expect.
