| Latest Review Posted | Sigma EX DC J 10-20mm F4-5.6
Bought secondhand for £180 and in first class condition. First impressions very favourable. Looks and feels like a real quality lens. A small downside to that is it is a little hefty. But balances well with the K5.
Optics are supreme. Perhaps a little soft in the corners at 10mm when wide open. Stopped down a little though and its brilliant, right through its focal range. It also resists CA pretty well. There is some vignetting at 10mm but can be corrected in post.
Focus is just screw drive on the pentax version, Nikon and Canon versions get HSM for the same price......why???? A little unfair. But that said it focuses well enough and not too noisy either. Focusing is done internally which means no rotating front element, which also means no problems using a polariser or Grad filters with this lens.
Finally, value. Always a trump card for Sigma and they play it well again with this lens. Represents truly excellent value for money, new or secondhand. Most reviews put it ahead of the similary priced Tamron 10-24. A way below the price of the Pentax 12-24 option.
My only reservation would be whether it represents the best option when compared to its stablemates from Sigma. Sigma also offer a 8-16, 10-20 f3.5 and 12-24. All of which are optically superior to this lens. And the EX 10-20 f3.5 only costs an extra £50 new and for that you get the HSM focus motor, constant f3.5 and a notch up in optical quality. |
